I suggest you stick to the genuine Skoda jack and foam kit. As well as the jack locating correctly on the jacking point, they aren't expensive. So many of these universal jacks will take the paint off and cause rusting on the jacking point...so best avoided. The jack and foam kit for the Superb MK3 (not 272/280HP or hybrid models) has an OEM part number of 3V0093860D and is listed at 2199CZK (about £75.54) on the "skoda eshop cz" website. I doubt they ship to the UK being a Czech website but you should be able to order it from any VAG parts department using the 3V0093860D part number. This kit will include everything except for the actual spare wheel. If you have a 16" Superb MK2 wheel it probably has a specification of 205/55R16 fitted to a 7Jx16 ET45 5/112 57.1 rim. This would have an actual inflated width of about 220mm, not the 205 that you see on the tyre's sidewall. It might be the case that a tyre with an actual inflated width of more than 215mm will lift the carpet in the boot, but you might get lucky (or maybe not) with this 220mm actual inflated width spare tyre because the ET45 offset is 4mm more than the 205/65R16 fitted to a 6.5Jx16 ET41 rim that one owner tried and succeeded with, ie. it didn't lift the carpet. A 205/65R16 fitted to a 6.5J rim has an actual inflated width of 215mm. The standard 16" wheel on the Superb MK3 is 215/60R16 fitted to a 6.5Jx16 ET41 rim, and that has an actual inflated width of 221mm and does raise the carpet slightly when fitted in the spare wheel well. jack and foam kit for the Superb MK3 (not 272/280HP or hybrid models) OEM part number 3V0093860D (listed at 2199CZK which is about £75.54) https://eshop.skoda-auto.cz/cs_CZ/sada-pro-vymenu-rezervniho-kola-16/p/3V0093860D A possible spare wheel which has been successfully tried on a Superb MK3 (not 272/280HP or hybrid model) is a 205/65R16 fitted to the standard 16" rim, ie. 6.5Jx16 ET41 5/112 57.1 Vredestein Ultrac 205/65R16 95W (Euro label A A 70dB) https://www.mytyres.co.uk/rshop/tyre/Vredestein/Ultrac/205-65-R16-95W--/R-454757 Alcar 8426 6.5Jx16 ET41 5/112 57.1 steel rim https://www.mytyres.co.uk/rims/details?vehicleId=182143996746511472&rimCode=ALCAR8426

They are called Luna alloy rims from the Superb MK2 with OEM part number 3T0601025K as shown below. The standard offset for the 18" Octavia MK2 rims is ET51, whereas the 18" Superb MK2 rims use 5mm less offset, ie. ET46...so the centre of each wheel moves out by 5mm each side in the wheelarches. 3T0601025K 7ZS (chrome coloured metallic) 7.5Jx18 ET46 5/112 57.1 https://www.lllparts.co.uk/catalogs/skoda/CZ/SUP/632/6/601/601080

The sticker in the boot only has a small selection of the car's build codes...perhaps around 40 of them. The car might actually have around 180 build codes, so a lot more than what is shown on the sticker in the boot.

There's a seller on ebay who can supply all the car's build codes and factory options for about 3 Euros (about £2.50). This will tell you what wheels the car came out of the factory with. According to Jurid on autodoc, the Octavia MK2 2.0TDI 140HP has 288x25mm front brakes discs, so 15" wheels would clear the front brake calipers.

If it's the original stop-start battery it will probably be the inferior EFB type rather than the superior AGM type. Probably best just to fit a new battery and see if that sorts the problem out. Varta are one of the best car batteries, so good that even Bosch rebrand them as their own. Varta have a battery finder on their website, although it's best to take physical measurements of the battery that's currently fitted. It's probably 175mm width and 190mm height, but length can vary in approximately 1.5" (38mm) increments...depending what the size is. The capacity that's marked on your current battery will also give a good indication of what size it is. It's something like 60Ah for a size 2, 70Ah for a size 3, and 85Ah for a size 4. Although make sure you do your own research so that you don't end up guessing. A length of 242mm (about 9.5") is a size 2 battery, a length of 278mm (about 11") is a size 3 battery, and a length of 317mm (about 12.5") is a size 4 battery. Bear in mind that AGM batteries have very low self-discharge compared to SLA (Sealed Lead Acid) batteries. I can't comment on the self-discharge rate of EFB batteries because I've never had one of those. Varta car batteries https://www.varta-automotive.com/en-gb/battery-finder

According to the Yokohama website, Geolandars aren't just AT (All-Terrain) tyres but they also have the 3PMSF symbol, which means they have passed a test for good traction in the snow. Having the 3PMSF symbol means a tyre is winter rated. So whether it's off-road, mud, gravel, snow, etc. the Geolandars should be able to cope. I've always found it strange that the Geolandars are listed in the summer tyre section, even though they have the 3PMSF (Three-Peak Mountain Snow Flake) symbol and are therefore all-season tyres as well as AT (All-Terrain) tyres. I suspect it's because they are all-terrain tyres that they put them in the summer tyre section...perhaps that's the traditional place for AT tyres.

All the factory fitted 16" alloy rims on the Yeti are 7J wide, ie. full specification 7Jx16 ET45 5/112 57.1

On the Yeti, Skoda fitted both 205/55R16 and 215/60R16 to 7J rim widths. On all of the Skoda cars over the years, Skoda fitted both 205/55R16 and 215/60R16 to 6J, 6.5J, and 7J rim widths. Hence, 7J is the widest rim that Skoda have fitted 205/55R16 and 215/60R16 to over the years. 6.5J is probably the most common rim width that Skoda have fitted 205/55R16 and 215/60R16 to over the years. The Scala fits its 205/55R16 to 6J rims, and the Karoq fits its 215/60R16 to 6J rims.

As you are keeping your 7Jx16 ET45 rims, changing from 205/55R16 to 215/60R16 would make sense.

The Octavia MK3 Scout uses 225/50R17 fitted to 7Jx17 ET45 5/112 57.1 alloy rims. The 17" rims on the Karoq also use 7Jx17 ET45 5/112 57.1 alloy rims, albeit with 215/55R17 tyres. However, these Karoq 17" rims are one option but with the 225/50R17 tyre size. Karoq 7Jx17 ET45 5/112 57.1 alloy rims https://eshop.skoda-auto.cz/cs_CZ/alu-kola/c/alloyWheels?q=%3ApriceAsc%3AcarType%3AKaroq%2B%282017%2B%29%3ArimDiameter%3A17&text=#

As a general guide, with the 205/55R16 tyre size on the Superb MK2 anything between 6J and 7J for the rim width and ET40 and ET45 will be ok. With the 205/55R16 tyre size, you could also consider ET46 to ET50 offsets, but the centre of the wheel will be pushed into the wheelarch resulting in a sunken look...especially as the offset approaches ET50. Bear in mind that 205/55R16 6Jx16 ET50 is a winter wheel specification for the Superb MK2 suitable for the use of snow chains...but unless you need to use snow chains there seems little point using an offset more than ET45. Skoda approved wheel specifications for the Superb MK2 205/55R16 7Jx16 ET45 225/45R17 7.5Jx17 ET49 225/40R18 7.5Jx18 ET46 As you can see in the ETRTO chart below, 205/55R16 can be fitted to a rim width between 5.5J and 7.5J...so using rim widths between 6J and 7J is not pushing the limits of what is possible. Skoda themselves have over the years fitted the 205/55 tyre size to 6J, 6.5J, and 7J rim widths on various Skoda models...but Skoda have never used 5.5J or 7.5J rim widths with the 205/55 tyre size...so you could say sticking to 6J to 7J rim widths for the 205/55 tyre size is a conservative approach. ETRTO approved rim widths for passenger car tyres 205/55R16 5.5-6.5-7.5

See the chart below. If you changed from 235/40R19 to 245/40R19, then you need to multiply your odometer by 1.012 to take into account that you are now travelling 1.2% further than your odometer indicates...assuming that the odometer is 100% accurate (unlikely) when on new 235/40R19 tyres. However, if you were basing your old fuel consumption figures on worn tyres, then the difference will be even more...perhaps you need to add about 3% to account for 6mm of tread wear on the old 235/40R19 when comparing to new 235/40R19. Outside diameter of tyres Old 235/40R19 with 6mm of tread wear 658.6mm New 235/40R19 670.6mm New 245/40R19 678.6mm (1.2% bigger outside diameter compared to new 235/40R19) New 245/40R19 678.6mm (3.0% bigger outside diameter compared to old 235/40R19 with 6mm of tread wear)

According to the gknautomotive.com online spring catalogue, the Superb MK3 1.6TDI 120HP estate has the following standard ride height springs.

There's a serious problem of an out of round tyre, caused by the tyre's beads not being fully seated on the rim. This fundamental problem needs to be addressed first. There might not be any problem with the tracking.

You can easily see (to a trained eye) that the tyre isn't fully seated at the top where it says DAVANTI. It's probably why the tyre has overheated at that point (ie. localized overheating) and destroyed the tyre. It's nothing to do with incorrect tracking, and also explains why the tyre didn't feel balanced and was losing air pressure. Because the tyre's beads aren't fully seated, the outside of the tyre is no longer round...which is why the tyre has suffered localized overheating...and the resultant delamination at that point. No amount of adding weights will correct the problem of an out of round tyre. Because balancing a wheel with weights, you need to make sure the outside of the tyre is round...by making sure the tyre's beads are fully seated on the rim.

It looks like that cheap Chinese Davanti tyre isn't fully seated on the rim. The tyre fitter was really incompetent not to have noticed that. When a tyre fitter fits a tyre to a rim, he should inflate the tyre until the tyre's beads are fully seated on the rim. If he is having difficulty fully seating the tyre's beads, he should remove the tyre from the rim and apply more tyre lubricant to the tyre's beads...and then try again to fully seat the tyre's beads to the rim. The problem may be that the cheap low quality Chinese tyre isn't fit for purpose...which may have contributed to the tyre fitters difficulty in fully seating the tyre's beads to the rim. If the tyre fitter couldn't seat the tyre's beads fully to the rim, he should have rejected that tyre and chosen another tyre to fit. Is the wear the same around the full circumference of the tyre?

Most summer tyres in size 225/45R18 are Y speed rated. For example, mytyres are currently listing 161 summer tyres in size 225/45R18. 152 of those tyres have a speed rating of W or higher, so only 9 of those 161 tyres have a speed rating of V or lower. It might be cheaper for Skoda to purchase Y rated tyres in this size compared to V rated tyres because it's the Y rated tyres in this size that the tyre manufacturers are geared up to manufacture in large quantities. It also means that Skoda can fit all of the 225/45R18 summer tyres that they order in to any Octavia MK4 including the ones with a top speed over 150mph. For the Octavia MK4, "skoda eshop cz" are showing that Skoda supply H speed rated winter tyres in size 205/60R16 and V speed rated winter tyres in sizes 205/55R17, 225/45R18, and 225/40R19.

If they are genuine VAG alloy rims the OEM part number will be cast into the back of the rim. They might be 1Z0601025AD 7ZS as shown in the chart below. There's a black version shown in the "skoda accessory catalogue" which might still be available to order new from any VAG parts department by quoting OEM part number 1Z0071498A. Notice that alloy rims in the "skoda accessory catalogue" use the format xxx071xxx whereas the factory alloy rims use the format xxx601xxx.

215/40R17 is an expensive and hard riding tyre size. 15" wheels such as the standard 185/60R15 fitted to 6Jx15 ET38 rims would make a lot more sense. 15" tyre sizes in general are much cheaper than 17"...often less than half the price. Here is just one example, and I've listed 5.5Jx15 ET40 rims from the Fabia MK4 rather than the standard Fabia MK3/Rapid 6Jx15 ET38 because the slightly narrower 5.5J rims not only helps to improve the ride even more compared to the wider 6J rims but the tyres' sidewalls will bulge out slightly more resulting in even better protection from kerbing damage.

You would then have your old wheels to resell and recoup some of the cost. The UK price for the wheel trims might be a little more than the Czech price when ordered through a UK VAG parts department. Although you can get 17" tyres that might be a small improvement over your current 17" tyres, these 15" tyres will put the car's ride in a completely different league.

Someone suggested that Skoda stopped sticking the white build code label in the spare wheel well area after around 2015/16. So you might not have one, although the exact date Skoda stopped sticking the white build code label in the spare wheel well area might vary from model to model. However, Skoda only included around 40 of the build codes, when the car might actually have around 180 build codes...so most aren't included. There's an ebay seller that can supply all of the build codes for about 3 Euros (about £2.50). Search "skoda vin decoder" on ebay to find the listing.

It would be interesting to hear if anyone else with an Octavia MK3 diesel VRS 2WD pre-facelift also had 312x25mm front brake discs. Perhaps Skoda started fitting the smaller front brake discs before the facelift...perhaps from 2016. However, it's always best to check the car's build codes to be sure what equipment was fitted in the factory.
