Wheel size.

Hi guys. Wondering if anyone knows what is the minimum size wheel that wil fit on a 2022 VRS and clear the calipers. Am thinking about trying to put a real spare tyre together.

If it uses 340x30mm front brake discs, then 17" rims will be the minimum diameter to clear the front brake calipers.

 

The standard 17" wheel size on the Octavia MK4 is 205/55R17 fitted to either a 6.5Jx17 ET46 or 7Jx17 ET46 rim.

 

One non-standard option could be 225/50R17 fitted to 7Jx17 ET45 rims from the Karoq, such as the rims shown below.

@shempy   Do you want a Real Spare with the identical tyre circumference / total diameter to what is on the car.

 

Or are you after an Emergency Spare / Steel wheel narrower and tyre that fits in and is not lifting the floor and nearly an identical circumference of tyre?

Thanks for the replies.Not overly impressed with the space saver supplied.Was hoping to have a tyre with the same diameter (if it fits in the wheel well) Doesn't need to be quite as wide as my road tyres.

17 inch is a bit tight for a petrol VRS which has bigger front brakes, it will fit but might clash with the balance weights 18 inch would be better with 225-45-18 tyres.

If that were true, you wouldn't be able to use the car in the winter in some parts of Europe because Skoda don't approved any wheels bigger than 17" for the fitment of snow chains to the Octavia MK4.

 

The following information about snow chains is in the Octavia MK4 owner's manual. You wouldn't be able to use the 16" wheel option with the 340x30mm front brake discs.

 

Skoda approved tyre and rim combinations for mounting snow chains (Octavia MK4)

205/60R16 6.5Jx16 ET46

205/55R17 6.5Jx17 ET46

 

A Kodiaq owner once posted a photo of his 17" alloy rims clearing his 340x30mm front brake discs...and it showed that there is plenty of clearance. Like the Octavia MK4, Skoda don't approve any wheels bigger than 17" for the fitment of snow chains to both the Kodiaq MK1 and Kodiaq MK2...and all Kodiaqs with more than 150HP use those big 340x30mm front brake discs.

 

The Superb MK3 owner's manual also shows that you can't fit wheels bigger than 17" with snow chains...and the 272HP/280HP models have those big 340x30mm front brake discs.

 

The below Octavia MK3 VRS has 340x30mm front brake discs because it's a pre-facelift model...and all pre-facelift VRS models have those big 340x30mm front brake discs (even the diesel VRS). It was only after the facelift that the diesel VRS models were fitted with the smaller 312x25mm front brake discs...whereas the petrol VRS models kept those big 340x30mm front brake discs. You can tell it's a pre-facelift model because the headlights aren't split.

6.5x17" rim with 205/55 tire is the smallest approved tire for the mk4 TSI RS Octavia with 340mm brake discs.

These are homologation approved dimensions from factory:

Thanks all. Really helpful.

That's incorrect, I had two pre-facelift vRS diesels, a 2013 with the 340mm discs and a 2016 with the 312mm discs.

Was the 2016 Octavia MK3 VRS a 4x4?

 

Was it built for the UK market?

 

Ferodo and Jurid on autodoc list just the 312x25mm front brake discs for the Octavia MK3 2.0TDI 184HP 4x4, so it looks like the 184HP 4x4 model never used the 340x30mm front brake discs.

Both were FWD UK cars.

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.
