Hello all happy new year !  I wondered if a set 6.5j 17" steel wheels would meet requirements for my mk2 2.0 tfsi VRS? They are brand new and off an Octavia 1.8 fsi so the PCD and bolt pattern are fine with an ET of 50 which is also fine. They have a new set of 205/50R17 tyres as well. I just need to know if I can just change my wheels over without hindering anything or too much . comments very welcome Many thanks. 

Sounds all good, but what size tyres are on the car now? 

Cheers toot, they are 225/40/R18 alloys . Just to confirm after researching rims & tyres for Octavia family I can only find 7j for the 2.0 engines 170psi - 200psi and the 6.5j 17" are fitted to the 1.8 tfsi 160psi. 

* current tyre set up is 225/40/R18 on 18"alloys (7.5J I assume) looking to fit 205/50/R17 on a set of 17" steels on a 6.5j - I suppose when I mean meet requirements I mean will the change in tyre size effect speedo reading tolerance and is there any safety concerns being 6.5j on a 2.0 tfsi. I'm just doing a sanity check in-case I have overlooked something stupid (which I do time to time lol.. )

 

Sit the wheels / tyres side by side.  No real difference in circumference,

 / total diameter.

No issues with the speedo. It over reads now and will when you fit the new ones.

Nice one toot, that calculator is very useful thank you. Sanity check over and now time to make the purchase and the change. Thank you

helpful specification I found for my 2011 mk2 vrs 2.0 tfsi Octavia wheel rim and tyre: for the VRS you need a minimum of 16" rim (due to the size front callipers) and 6.5j on the width

• Bolt pattern (PCD): 5 × 112
• Center Bore (CB): 57.1
• Thread size (THD): 14 × 1.5
• Aspect ratio: 40 — 65
• Smallest — Largest tire size: 195/65R15 — 225/40R18
• RIM SIZES BELOW:
• Diameter: 15 — 18
• Width: 6 — 7.5
• Offset: 47 — 54

If they are Kodiaq steel rims the specification is 6.5Jx17 ET38 5/112 57.1, not ET50

 

205/55R16 are a much cheaper tyre size than 205/50R17.

 

However, being a VRS you may prefer the lower aspect ratio.

 

205/50R17 tyres are usually fitted to a rim with an offset of ET50 on the Octavia MK2. So using ET38 rims is like fitting 12mm spacers to the ET50 rims, as 12mm spacers changes the effective offset of ET50 rims to ET38.
