The year 2001 also looks a bit dodgy because the Superb MK2 didn't come out until 2008...and the Superb MK2 with 1.6TDI engine didn't come out until 2010. So it must be 2010 or later.

Is the specification 6Jx16 ET35 5/100 57.1 such as the Alcar 6664 listed on mytyres, oponeo, and autodoc? If so, then go for a 205/60R16 if it will fit in the spare wheel well. If it's a bit too wide, then go for 195/60R16. 205/60R16 is a cheaper and more common tyre size than 195/60R16.

The biggest front brakes fitted to the Fabia MK3 are 288x25mm, so 15" rims will fit all models.

Those rims on facebook won't fit the Fabia, because they have a 5/112 hub centre bore. Fabias use a 5/100 hub centre bore, so 5/112 won't fit. Those 15" alloy rims are in the VW Golf parts catalogue, as shown below. 1K0601025CA Aluminium rim BRISTOL 6.5Jx15 ET50 5/112 57.1 1K0601025CA 8Z8 Diamond silver https://www.lllparts.co.uk/catalogs/vw/RDW/GOLF/474/6/601/601050 The biggest front brakes fitted to the Fabia MK3 are 288x25mm, so 15" rims will fit all models. The specification of the 16" wheels on the Fabia MK3 is 215/45R16 7Jx16 ET46 5/100 57.1 The specification of the 15" wheels on the Fabia MK3 is 185/60R15 6Jx15 ET38 5/100 57.1 Skoda has a competitively priced "alloy rim accessory catalogue". Often these will be the same alloy rims as the factory ones, but with a different OEM part number cast into them...and a consequently much lower price. The four different styles of 15" alloy rims for the Fabia MK3 shown in the Skoda accessory catalogue weigh between 7.5kg and 8.3kg. If you make a note of the OEM part number shown for any of the alloy rims shown in the Skoda accessory catalogue, you can order them from any VAG parts department. For example, 5JA071495A 8Z8 is the OEM part number for the "Propeller" alloy rims. 8Z8 is the associated 3-digit colour code, and means silver. Fabia MK3 6Jx15 ET38 5/100 57.1 alloy rims (from the Skoda accessory catalogue) https://eshop.skoda-auto.cz/cs_CZ/alu-kola/c/alloyWheels?sort=priceAsc&q=%3AscoreDesc%3ArimDiameter%3A15%22%3AcarType%3AFabia%2BIII%2B%282014%2B%29# As well as the standard 185/60R15 tyre size, you might also want to consider a slightly oversize 195/60R15 on those 6J rims as this would not only give an even better ride, but better protect the alloy rims from kerbing damage (because the sidewalls will bulge out about 3mm more each side, compared to the narrower 185/60R15 tyre size). See the chart below for the actual inflated tyre width of these two tyre sizes when fitted to a 6J rim width. Notice that the actual inflated width of the tyre isn't usually the same as its "nominal" width. The "nominal" width is what's shown on the tyre's sidewalls. The actual inflated width of a tyre always depends on the rim width to which it is fitted. Actual inflated tyre width 185/60R15 fitted to 6J rim 195mm 195/60R15 fitted to 6J rim 201mm Vredestein Quatrac 195/60R15 88H https://www.camskill.co.uk/m138b0s7993p202144/Vredestein_Tyres_All_Season_Car_Vredestein_Quatrac_6_195_60_R15_88H_TL_Fuel_Eff_%3A_C_Wet_Grip%3A_B_NoiseClass%3A_B_Noise%3A_70dB Another option is 15" rims from the Fabia MK4. These are 0.5" narrower than the Fabia MK3 rims. so would not only better protect the alloy rims from kerbing damage but give a slightly better ride. These "Hadar" rims are only 7.2kg each, so are a little lighter than the Fabia MK3 alloy rims. 185/60R15 fitted to a 5.5J rim would give a similar amount of protection from kerbing damage as a 195/60R15 fitted to a 6J rim. As you can see in the chart below, the 185/60R15 fitted to a 5.5J rim width is 12mm (about 0.5") narrower than a 195/60R15 fitted to a 6J rim width. So although the 185 tyre is now 0.5" narrower than the 195 tyre, the rim it is fitted to is also 0.5" narrower...meaning that the sidewalls on the 185 and 195 tyres both bulge out from the alloy rim about the same amount...resulting in a similar amount of protection from kerbing damage. Actual inflated tyre width 185/60R15 fitted to 5.5J rim 189mm 185/60R15 fitted to 6J rim 195mm 195/60R15 fitted to 5.5J rim 195mm 195/60R15 fitted to 6J rim 201mm For ultimate ride comfort and rim protection 195/60R15 fitted to a 5.5J rim could be the way to go. The one very minor disadvantage with fitting a 185/60R15 to a rim with an ET40 offset is that it moves the centre of the wheel 2mm inwards compared to the standard ET38 offset, so by using the slightly wider 195/60R15 this very minor problem is completely negated. In fact some markets used a 195/55R16 tyre size on a 6Jx16 ET40 rim on the Rapid (which was based on the Fabia MK3)...so using a 195 with an ET40 offset on this chassis has already been done by Skoda.

If you need new centre caps for the alloy rims, you should be able to order them from any VAG parts department. They should fit those Audi rims, because they also use a 57.1mm hub centre bore.

You can order a spare wheel kit from any VAG parts department using OEM part number 5E0093860F. The kit includes everything except for the actual space saver spare wheel, which would need to be ordered separately. I suggest you first order just the spare wheel kit (without the actual space wheel). Then you can work out if you can fit a full size spare wheel. As you have a VRS facelift, you will need at least 17" rims to clear the front brake calipers. I doubt you would have enough room for a 225 tyre width, but maybe a 205/50R17 fitted to a 6.5Jx17 ET49 5/112 57.1 steel rim (from a VW Caddy 2020 onwards) would fit...but there might only be enough room for a space saver spare wheel.

8D0601025C is the same OEM part number as 8D0601025C Z17. Z17 is simply the associated three digit colour code, ie. Avus silver. 7Jx16 ET45 5/112 57.1 is one of the Skoda approved rim specifications for the Superb MK2.

Is the 12.36 Volts measurement taken directly on the battery terminals? If you measure the Voltage at the cigarette lighter socket, the reading will be less than when measured directly at the battery terminals. If the Voltage is 12.36 Volts measured directly at the battery terminals, then the battery voltage is too low. I've recently got a new Varta (Silver Dynamic) lead acid battery, and 3 weeks after fully charging (using a Bosch fully automatic smart charger with a low 3.5 Amp charge rate) the voltage was still over 12.7 Volts without it being connected to the car or used. So with a good battery, the Voltage will hold up well even if it's not being used. If you've got a good battery, a car should still start even after 6 to 8 weeks of the car not being used.

On the Superb MK3, a 15" rim won't clear the front or rear brake calipers. This is because the smallest brake discs that the Superb MK3 uses is 312x25mm front and 300x12mm rear. Skoda do supply a 205/55R16 6.5Jx16 ET46 5/112 57.1 spare wheel from an Octavia MK3 for the Superb MK3. However, this is clearly an economy measure and not a very good choice for owners who are a little more discerning than Skoda. Octavia MK3 205/55R16 6.5Jx16 ET46 5/112 57.1 spare wheel https://eshop.skoda-auto.cz/cs_CZ/rezervni-kolo-16-neplnohodnotne/p/5E0601011J As you can see in the chart below, the 205/55R16 is a whopping 4.9% smaller than 215/60R16. Outside diameter of tyre 215/60R16 664.4mm 205/55R16 631.9mm (4.9% smaller outside diameter than 215/60R16)

The Roomster has either 256x22mm or 288x25mm front brake discs. If it has the smaller front brake discs then 14" rims will clear the front brake calipers. If it has the bigger front brake discs then 15" rims will clear the front brake calipers.

What make and model of rear shock absorbers did you purchase? I've looked at the Skoda parts catalogue and there aren't any increased ride height springs and shock absorbers for the Roomster. Finding suitable rear shock absorbers for the Roomster couldn't be easier, because there is only one OEM part number for the rear shock absorbers on the Roomster...1J9513025F Skoda part catalogue https://www.lllparts.co.uk/catalogs/skoda/CZ/RO The standard suspension on the Roomster is similar to increased ride height suspension on other similar cars such as the Fabia MK2. A similar thing happens on the Yeti, where the standard suspension on that car is similar to increased ride height suspension on the Octavia MK2. Hence, you can't get increased ride height suspension on cars like the Roomster and Yeti because their standard suspension is already increased ride height.

As you can see in the chart below, the 125/70R16 tyre size has an outside diameter a whopping 10.9% smaller than the standard 16" Octavia MK4 tyre size. Even a 5% difference would be quite a lot. Outside diameter of tyre 205/60R16 652.4mm 135/90R16 649.4mm (0.5% smaller outside diameter compared to 205/60R16) 125/90R16 631.4mm (3.2% smaller outside diameter compared to 205/60R16) 125/85R16 618.9mm (5.1% smaller outside diameter compared to 205/60R16) 125/80R16 606.4mm (7.1% smaller outside diameter compared to 205/60R16) 125/70R16 581.4mm (10.9% smaller outside diameter compared to 205/60R16) The Seat Leon MK3 does have both 125/70R16 and 125/70R18 listed in the Seat parts catalogue as shown in the link below.

125/70R16 is tiny. Is it 125/70R18? If it is 125/70R18, then you could use that because it is the correct size space saver tyre for the Octavia MK4 (even though it has an outside diameter a little bit smaller than the standard Octavia MK4 tyre sizes)...and will be fitted to a 3.5Jx18 ET25.5 5/112 57.1 steel space saver rim. The kit is all you need (apart from the actual spare wheel) and includes support for the carpet, etc. Octavia MK4 spare wheel kit 5E3093860B

Bilstein haven't given you any specifics about why they wouldn't fit or be suitable. If the Scout was tested, why weren't the Bilstein B6 shock absorbers for the Passat B8 Alltrack suitable bearing in mind that both cars use almost the same springs...so close that Kilen/Lesjofors sell the same front springs to use on either car. Until recently, I think Bilstein would have said the same thing about the Superb MK3 with standard ride height. Bilstein can't recommend anything unless one of their engineers signs it off as safe...and that clearly hasn't happened.

Will an inflated 225/45R17 7Jx17 ET49 5/112 57.1 fit in the spare wheel well without raising the carpet? If not because it's too wide, you could consider using a 205/50R17 6.5Jx17 ET49 5/112 57.1. The VW Caddy 2020 onwards uses a steel rim in this specification rim. The Caddy uses a 215/55R17 on that size rim, which is too big for the Octavia MK3. The 205/50R17 would better match the 225/45R17, compared to the more common 205/55R16 6.5Jx16 ET46 5/112 57.1. However, I don't think it would be a big advantage using a 205/50R17 6.5Jx17 ET49 5/112 57.1 rather than the more common (and Skoda approved) 205/55R16 6.5Jx16 ET46 5/112 57.1 because it would be best to fit either to the front so that the unbalanced car understeered rather than oversteered. 5E0071497A 8Z8 is from the accessory catalogue, and aren't factory fitted alloy rims. The factory fitted equivalent is 5E0601025E 8Z8. Not all alloy rims in the accessory catalogue have a factory equivalent, and vice-versa. Notice that the format xxx071xxx means the alloy rim is from the accessory catalogue. The xxx601xxx format means they are factory fitted rims or are from the normal Skoda parts catalogue. When purchasing new, xxx071xxx alloy rims are often well under half the price of the equivalent xxx061xxx rims. This is so that Skoda can compete with aftermarket alloy rims on price. There aren't always direct equivalents, but 5E0601025E 8Z8 and 5E0071497A 8Z8 do appear to be the same rim, except for the part number. They both have a specification of 7Jx17 ET49 5/112 57.1 and will normally be fitted with a 225/45R17 tyre size on the Octavia MK3. Most of the secondhand alloy rims will have the xxx601xxx format, because they are far more common than alloy rims supplied from the Skoda accessory catalogue.

Until recently, the Bilstein B6 standard ride height shock absorbers weren't listed in the Bilstein catalogue for the Superb MK3. So they were saying exactly the same thing about those, even though the Bilstein B6 shock absorbers for the Passat B8 also fitted the Superb MK3.

It sounds like the car's shock absorbers aren't very good. I expect the Bilstein B6 Alltrack shock absorbers would transform the ride and handling. If the ride is a little firm, it would be a simple task to change down to 17" wheels. Perhaps 225/55R17 7Jx17 ET40 (oversize tyre size on standard rims) or 215/55R17 6.5Jx17 ET38 (standard tyres on Kodiaq rims). 225/55R17 is an Alltrack tyre size. 6.5Jx17 ET38 5/112 57.1 steel rim (from Kodiaq) https://eshop.skoda-auto.cz/cs_CZ/plechovy-disk-17-/p/5QF601027J+03C Ratikon 7Jx17 ET40 5/112 57.1 alloy rim (from Kodiaq, same specification as Superb MK3) https://eshop.skoda-auto.cz/cs_CZ/alu-kolo-ratikon-17-kodiaq/p/565071497A+8Z8

The difference in sidewall height between the 235/45R18 and 245/45R18 tyre sizes is 4.5mm, or 5mm rounded up to the nearest millimetre. Sidewall height 235/45R18 = 105.75mm 245/45R18 = 110.25mm

The front and rear springs are very similar between your Superb MK3 280HP Scout and the Passat B8 Alltrack. The Passat B8 Alltrack has slightly stiffer springs, but only about 0.25mm increase in wire diameter which is about 5% stiffer. The front springs are so close that Kilen/Lesjofors sell the same aftermarket front springs to replace both 5Q0411105HS (your front spring) and 5Q0411105DP (Passat B8 Alltrack front spring). Lesjofors 4095142 front spring (sold to replace both 5Q0411105HS (your front spring) and 5Q0411105DP (Passat B8 Alltrack front spring) https://www.autodoc.co.uk/lesjofors/15270767 The 151mm ground clearance for the Superb MK3 Scout seems incorrect, if the Passat B8 Alltrack is 174mm. The Superb MK3 Scout is clearly increased ride height just like the Passat B8 Alltrack. If it wasn't, you wouldn't have almost the same front and rear springs as the Passat B8 Alltrack. As the Superb MK3 Scout springs are similar to the Passat B8 Alltrack springs it's probably better to use the Bilstein B6 shock absorbers that are listed for the Passat B8 Alltrack on the Superb MK3 Scout, rather than the standard ride height Bilstein B6 shock absorbers. The Bilstein B6 shock absorbers for the Passat B8 Alltrack are probably a little longer than the Bilstein B6 shock absorbers for the standard ride height car. This is because the front shock absorbers on the standard ride height car use bump stops with a 70mm height, whereas the front shock absorbers on the increased ride height car use bump stops with a 90mm height. So if the front shock absorbers on the standard ride height and increased ride height cars were the same, using 90mm bump stops would reduce the front suspension travel by 20mm on the increased ride height car. Hence, it would make sense for the increased ride height car to have longer front shock absorbers than the standard ride height car.

Lesjofors 4285707 are the same as Kilen 63106, and are both made in the same factory in Sweden.

The problem with those charts is that they assume the speedometer is 100% accurate when on standard tyre sizes. Car speedometers will often over-read by up to 5% when on standard tyre sizes, so it's worth checking with GPS.

If the centre bore is too big, eg. 66.6mm instead of 57.1mm you would have to use spigot rings. Spigot rings are different from spacers, as shown in the photo below. If you don't use spigot rings with a rim that has a hub centre bore that is too big, you could get wheel vibration because the rim might not be centred on the hub. I don't like spigot rings so would never use rims with the wrong hub centre bore. Photo of spigot rings

Bilstein 36-300075 is being sold to replace nine different rear springs, so is unlikely to be an exact match to 6Q0511115K. You could end up with a high rear end and/or rear springs that are too hard. Sachs 996657 is only being sold to replace 6Q0511115K, so should be an exact match. There are other springs that are also only being sold to replace 6Q0511115K, including Kilen 63106 and KYB RH6401, so again these should be an exact match.

Those charts are wrong because the widest part of a wheel isn't the rim, it's the inflated tyre. Actual width of inflated tyre 225/40R18 fitted to 7.5J rim 224mm 235/40R18 fitted to 8J rim 235mm So if you fit a tyre that has an actual inflated width of 235mm instead of 224mm, it will be 5.5mm closer to the strut assuming the offset is the same. If the offset is 3mm further out it will be 2.5mm closer to the strut. What is the full specification of the Audi rims you are looking at? The full specification looks something like this: 8Jx18 ET43 5/112 57.1 There was a big change in the hub centre bore when the Audi A4 B8 came out in 2008...the hub centre bore changed from 57.1mm to 66.6mm So if the rims are from one of these later Audi A4 cars the hub centre bore will be too big.

You might have difficulty finding all terrain tyres in the 205/55R16 tyre size. If so, perhaps consider oversize 215/60R16. However, 215/60R16 has a 4.3% bigger outside diameter than 225/40R18...which is a lot. Another consideration is the increase in radius, 215/60R16 has a 13.6mm increase in radius compared to 225/40R18. It's possible you could get rubbing with such a big change, although that might depend on what rim specification you matched the tyre to. 6Jx16 ET43 5/112 57.1 from the Karoq might be a good starting point. Steel rims in this specification weigh a surprisingly light 7.6kg. By comparison, your current 18" alloy rims probably weigh over 12kg.
