The Toyo may not have 4 grooves around the circumference, as sellers use generic photos. For example, you can see that mytyres is using the same photo for the following four Toyo CF2 tyre sizes: Toyo CF2 175/60R14 https://www.mytyres.co.uk/rshop/tyre/Toyo/Proxes-CF2/175-60-R14-79H/R-273326 Toyo CF2 175/65R14 https://www.mytyres.co.uk/rshop/tyre/Toyo/Proxes-CF2/175-65-R14-82H/R-252106 Toyo CF2 185/55R15 https://www.mytyres.co.uk/rshop/tyre/Toyo/Proxes-CF2/185-55-R15-82H/R-235623 Toyo CF2 195/45R16 https://www.mytyres.co.uk/rshop/tyre/Toyo/Proxes-CF2/195-45-R16-84V-XL/R-235657 175/60R14 is not a common tyre size. As you are buying a set, I suggest you use 175/65R14 instead. This will give you a lot more choice, lower prices, and a better ride. 175/65R14 has the same outside diameter as 185/55R15 and 195/45R16...which are two sizes that are sometimes used on the Felicia. As you are driving on mountain roads, I suggest you use all-season tyres that have the 3PMSF symbol. These will grip better on loose surfaces. And if the temperature in Greece drops below 7 degrees Centigrade you will have more grip than summer tyres. As you mentioned Hankook, here's the Hankook Kinergy H750 all-season tyre. It's a directional tyre which I'm not a fan of so I would be looking at the Vredestein Quatrac 5 or Dunlop Sport All Season in the 175/65R14 size. https://www.mytyres.co.uk/rshop/tyre/Hankook/Kinergy-4S-H750/175-65-R14-82T-4PR-SBL/R-378203

The tow-bar rear springs can also be called heavy duty rear springs, as you don't need a towbar to fit them. Tow-bar/heavy-duty rear springs tend to have a wire thickness about 0.5mm thicker than standard, which makes them about 10% stiffer than standard. If the OP feels that his rear springs are too soft, then fitting 10% stiffer rear springs isn't going to make the ride "crashy". Kilen actually recommends the tow-bar/heavy-duty rear springs for the OP's car, whereas gknautomotive recommends the standard rear springs. Rear springs are always going to be a compromise simply because of the widely different rear axle weights that you can have. Just two front passengers and there's not much weight on the rear springs. Add two or three rear seat passengers and all there luggage, and maybe add a large caravan into the mix and the standard soft rear springs will start to become overwhelmed. So maybe a 600kg rear axle weight with a lightly loaded car to 900kg with a heavily loaded car. Clearly, no one pair of rear springs are going to be optimal for all conditions. It's not just the spring rates, but the tyre sizes that play an important part in ride comfort. 195/65R15 and 205/55R16 are good, whereas lower profile tyres can reduce the ride comfort by an easily noticeable amount.

When you order a car with a factory fitted towbar, you will get stiffer rear springs that don't change the unladen ride height compared to the same car that came out of the factory without a towbar. However, it's not so easy to change the front springs without changing the unladen ride height. For example, if someone with a standard ride height Octavia MK3 1.6TDI fits front springs from a standard ride height Octavia MK3 2.0TDI the ride height will increase. This is because the 2.0TDI engine is heavier than the 1.6TDI engine.

If you only want to swap front to rear tyres once during the tyres lifetime, then you need to decide in what ratio the front and rear tyres would wear out if you didn't swap them front to rear. For example, if you expected your front tyres to wear out twice as quickly as the rears then you would swap after the fronts had worn down by two-thirds of their usually life, and the rears would have only worn down by one-third at that point. So if you had 6mm of usable wear you would change over when the fronts had 4mm of wear and the rears had 2mm of wear. Then all four tyres would wear out at the same time. If you only had 4.5mm of usable tread depth (for example, if you like to fit new tyres well before they get down to the legal minimum of 1.6mm tread depth) and your tyres wear down in the ratio 2:1 (ie. the fronts wear down twice as quickly as the rears), then you would change front to rear when the fronts had 3mm of wear and the rears had 1.5mm of wear. Then the rears (that are now on the front) would wear down by 3mm while the fronts (that are now on the rear) would wear down by 1.5mm. (ie. 3mm + 1.5mm = 1.5mm + 3mm)

The Kilen online catalogue lists both standard ride height springs and increased ride height springs for the Octavia MK3 estate 1.6TDI 105HP. https://web.tecalliance.net/kilen/en/parts/cars/assigned?assemblyGroupId=100113&targetId=58766&typeNumber=58766&targetCountry=AT&groups=188&brands=176&page=0#@brc/brands:Car;targetType:cars/assem:SKODA%20OCTAVIA%20III%20Combi%20(5E5%2C%205E6)%201.6%20TDI;targetType:cars;targetId:58766;typeNumber:58766;targetCountry:AT/lnkparts:Coil%20Springs;targetType:cars;assemblyGroupId:100113;targetId:58766;typeNumber:58766;targetCountry:AT;groups:188;brands:176;page:0 The following springs will increase the ride height by about 15mm Front spring with 15mm increased ride height (OEM part number 5Q0411105HN) Kilen 23132 KYB RA1122 https://www.autodoc.co.uk/car-parts/oem/5q0411105hn?search=OEN Rear spring with 15mm increased ride height (OEM part number 5Q0511112BD) Kilen 63141 KYB RA7155 https://www.autodoc.co.uk/car-parts/oem/5q0511121bd

215/60R16 is the normal size for 16" Karoq tyres.

I haven't done this particular job, so probably best to ask someone with hands on experience.

There's no need to change the ride height. Just fit rear springs that are two weight ranges stiffer than what you have at the moment. Up until about 2008 Skoda did fit firm rear springs to the Octavia and Superb, but many owners weren't carrying much weight around in the back so they found the standard suspension too hard. Hence around this time Skoda started fitted rear springs that were two weight ranges softer. All you have to do is go back to what Skoda did before they softened the rear suspension. You probably have 5Q0511121AD or 5Q0511121AE rear springs. Simply change these to 5Q0511121AF or 5Q0511121AG rear springs. Check the wire diameter of the rear springs that are currently fitted...probably around 10.75mm. The 5Q0511112AF and 5Q0511121AG rear springs have a wire diameter of around 11.25mm, so around 10% stiffer. https://web.tecalliance.net/gkn/en/parts/1/87627/detail?targetType=cars&targetId=59078&typeNumber=59078&groups=188#@brc/brands:Car;targetType:cars/assem:SKODA%20OCTAVIA%20III%20Combi%20(5E5%2C%205E6)%201.6%20TDI;targetType:cars;targetId:59078;typeNumber:59078/lnkparts:Coil%20Springs;targetType:cars;assemblyGroupId:100113;targetId:59078;typeNumber:59078;groups:188;brands:1;page:0/detail:87627;brandId:1;articleNo:87627;targetType:cars;targetId:59078;typeNumber:59078;groups:188 https://skoda.7zap.com/en/cz/octavia/oct/2016-753/5/511-511000/ (1) 5Q0 511 121 AD coil spring 2 PR-1JA+0YD (1) 5Q0 511 121 AE coil spring 2 PR-1JA+0YE (1) 5Q0 511 121 AF coil spring 2 PR-1JA+0YF (1) 5Q0 511 121 AG coil spring 2 PR-1JA+0YG https://skoda.7zap.com/en/cz/octavia/oct/2016-753/5/511-511000/ Kilen 63140 are sold to replace both 5Q0511112AF and 5Q0511121AG and are available on ebay for under £32 each. https://www.ebay.co.uk/itm/234236638466?hash=item3689977502:g:PQEAAOSws-hhaMT2

It looks like there are two versions of the 7.5Jx18 ET51 5/112 57.1 Neptune alloy rim depending on colour, as shown in the chart below. Make a note of the OEM part number for the version you have and do a search on ebay.co.uk and ebay.de Most of the sellers of secondhand alloy rims are trade sellers. They usually ask for quite high prices and will often wait months for a sale. It's a buyers market with older alloy rims, as there are large numbers of older cars getting scrapped all the time...and there simply aren't enough buyers for all these large quantities of secondhand spares. I expect you have the 1Z0601025AD version, as that is common and the other version seems to be very rare.

OEM part number for 312mm Audi TT front brake discs 8N0615301A It's best to use 310mm front brake discs rather than 312mm front brake discs as they are improved. 310mm have a minimum thickness of 22mm, whereas 312mm have a minimum thickness of 23mm. So 3mm of wear allowed on the 310mm discs, but only 2mm of wear allowed on the 312mm discs. 310mm and 312mm front brakes discs are interchangeable as they cover the same build codes and ATE don't sell the 312mm version. https://www.autodoc.co.uk/car-part The Audi TT MK1 uses an ATE front brake system (calipers, carriers, etc.) 310mm front brake discs s/brake-disc-10132/audi/tt/tt-8n3/17143-1-8-t?criteria[200][0]=310&criteria[100][1]=VA Audi TT MK1 front brakes https://audi.7zap.com/en/rdw/audi+tt+tts+coupe+roadster/att/1999-229/6/615-615025/#1

235/45R18 will be a good fit for a 7.5Jx18 ET51 rim when fitted to the Superb MK3 (or Passat equivalent). 215/50R18 will stretch the tyre to the max on a 7.5J rim, as the ETRTO allowable rim widths are 6J to 7.5J for that tyre size.

I have no problems with a 40HP car and 0-60mph in 20 seconds. I was just pointing it out as having so little power is quite unusual these days. If they made a 40HP electric Duster I might be interested. It might only cost about £2000 extra if the manufacturer didn't increase their profit margins as a Duster wouldn't cost much more to produce. However, that would upset the applecart and reduce sales of more expense cars on which larger profit margins are made. The lack of rear legroom in the Dacia Spring is a joke, although it's not the only cheap car that has that problem. It must be easy enough for manufacturers to make a car 2" to 4" longer so that there's a decent amount of rear legroom.

It looks like someone has repainted them, as this is what the silver metallic colour looks like. https://eshop.skoda-auto.cz/cs_CZ/kolo-z-lehke-slitiny-x-trem-19-pro-octavia-iii-rs/p/5E0071499B+8Z8 Many secondhand ones will be slightly buckled, as the super low profile 225/35R19 tyres offer the rims very little protection from pothole damage. If you do keep them, fitting 235/35R19 tyres and using the same tyre pressures as you would use for the standard 225/35R19 tyres will help a little against pothole damage. Fitting 235/35R19 instead of 225/35R19 only increases the sidewall height by 3.5mm, but the combination of using the same tyre pressures as 225/35R19 should combine to form a worthwhile improvement to resistance against pothole damage. Also 235/35R19 is only about 1% bigger in outside diameter than 225/35R19 so you will hardly notice the difference in gearing. Another problem with these super low profile tyres, is if you get a slow puncture as by the time you realise that you have one you may already have buckled your rim. The pothole resistance problem is bad enough when using standard tyre pressures on super low profile tyres, but when you are underinflated it won't take long before the car hits a bump in the road that buckles the rim. Check where the air is leaking from. You might just have a slow puncture. You can use soapy water to help find the lead, or remove the wheel and dip it in water. It's possible the rim isn't buckled. Sometimes a tyre fitter will damage the rim where the tyre bead sits against the rim, or the rim where the tyre bead sits may simply need cleaning up. Having air leak past the tyre bead is a common problem with alloy rims, but often easily solved with an alloy rim refurbishment.

No wonder your ride is so good...you went for the narrower 6Jx16 ET50 winter rims instead of fitting the 205/55R16 tyres to the wider 7Jx16 ET45 standard rims. Fitting tyres to narrower rims makes the sidewalls flex more easily and therefore gives a better ride.

195/65R15 and 205/55R16 are both Golf/Octavia sized tyres. People sometimes buy secondhand Golf MK4 6Jx15 ET38 alloy rims fitted with 195/65R15 tyres for their Fabias. I haven't heard of anyone that hasn't had problems with rubbing. 205/55R16 would be even worse as although it has the same outside diameter it's 10mm wider and uses less offset. You will only know for sure if you don't have a rubbing problem if you have tested the car in all conditions, with the suspension being fully compressed. Fitting tyres with little to no clearance is a bad idea. Sometimes you might not get rubbing in a straight line, but rubbing could occur under cornering forces such as driving around a roundabout or when there's a heavy load.

The outside diameter of either 205/55R16 or 215/55R16 is too big for the Fabia MK3. 185/65R15 or 195/55R16 is as big an outside diameter as you can go on the Fabia MK3. 185/60R15 tyres fitted to 6Jx15 ET38 5/100 57.1 rims is a standard fitment on the Fabia MK3, so maybe try that size...although the higher sidewalled 185/65R15 would provide even more comfort. 215/45R16 does give a "relatively" hard ride. 185/60R15 or 185/65R15 will be a lot better. If you want to stick with 16" rims, you need to change your relatively wide 7Jx16 ET46 rims to something narrower such as 6Jx16 ET35 (from the Skoda Scala) and fit 195/55R16 tyres. Steel rims are also available in this size and offset. However, the 15" option is better for comfort than the 16" option, but 195/55R16 on 6J rims is still a big improvement over 215/45R16 on 7J rims. 6Jx16 ET35 5/100 57.1 https://eshop.skoda-auto.cz/cs_CZ/kolo-z-lehke-slitiny-nanuq-16-pro-scala-kamiq/p/654071496B+8Z8 6Jx16 ET35 5/100 57.1 https://eshop.skoda-auto.cz/cs_CZ/kolo-z-lehke-slitiny-nanuq-16-pro-scala-kamiq/p/654071496C+FL8

225/45R19 is extreme on the Octavia MK3. That's a bigger outside diameter than Superb MK3 tyres.

On the Octavia MK3, the 19" rims use 225/35R19 tyres. Due to the super low sidewall height, they are very prone to buckling and other rim damage. Best to get them checked before handing over any cash. It's not unusual for 3 out of a set of 4 to be damaged. Make sure you have good breakdown insurance. A big pothole can easily take out both left wheels resulting in a big problem if you only have one spare wheel.

For the Octavia MK2 Scout, you could try 215/60R16 on 6J or 6.5J rims with an offset between ET43 and ET50. Perhaps rims such as 6Jx16 ET43 from the Karoq, or 6.5Jx16 ET43 from the Audi A3. The standard Octavia MK2 Scout uses 225/50R17 on 7Jx17 ET50 rims...hence with the narrower 215/60R16 tyre changing the offset by 7mm. This will keep the outside of the tyre's tread in roughly the same position in the wheelarch.

The problem with 8Jx18 rims fitted with 235/45R18 tyres is that the sidewalls don't bulge out much, so the rims are very exposed to kerbing damage. Going for a narrower 7.5J rim fitted with slightly oversize 245/45R18 tyres would massively improve rim protection as the sidewalls would bulge out quite a bit. 7.5Jx18 ET46 Alloy Rim https://eshop.skoda-auto.cz/cs_CZ/kolo-z-lehke-slitiny-trinity-18-pro-superb-ii-octavia-iii/p/3T0071498J+8Z8

It sounds like the 8Jx18 ET35 wheel from the wrecker is aftermarket as standard 18" Octavia MK3 rims don't use an offset anywhere near ET35. It's worth checking to see if one of your 225/40R18 wheels fits in the spare wheel well...I'm not sure it will fit when inflated (it probably will when deflated). If it doesn't fit (too wide) it might be worth considering 205/50R17 fitted to a 6.5Jx17 ET38 steel rim (or alloy rim) from the Kodiaq (as a spare). The VRS needs at least 17" rims to clear the calipers on the 340mm front brake discs...hence you can't use the usual 205/55R16 tyre fitted to a 6.5Jx16 ET46 steel rim (as a spare). 6.5Jx17 ET38 5/112 57.1 Steel Rim from Kodiaq https://eshop.skoda-auto.cz/cs_CZ/plechovy-disk-17-/p/5QF601027J+03C Octavia MK3 Spare Wheel Kits (Jack and foam, etc., but doesn't include the spare wheel) Notice that there are three types shown on the link below.

It doesn't make much sense getting a full size spare that doesn't match the specification of the other wheels, especially when it's so easy to get a 7.5Jx18 ET51 5/112 57.1 rim. It's not just the Octavia MK3 that uses the 7.5Jx18 ET51 5/112 57.1 specification 18" rim. The Golf MK7 and some other cars in the VW/Audi/Seat/Skoda group also use this specification.
