Downsizing wheels NLC

[smee]

Looking to replace the 18s on the Octavia with 16s.
Is there a conversion chart or site for tyres to keep the rolling radius the same?
Currently have 225/40/18s which is a) hopelessly impractical for my job and b) no use for winter.

Thanks

205/55/16 or 205/50/17 would work well.

You've probably already considered this, but make sure that 16s will clear the calipers..

You selling the 18's???

Will try fit a mk5 golf gti??

Was going to keep them maybe depending on how rubbish the 16s looked but may sell. Would need 2 new front tyres however

Is it an Octavia 1 or 2?

Octavia 1 = Golf 4
Octavia 2 = Golf 5 (different stud arrangement).

Not sure about width and clearance etc of course..

Octavia 2 = 5x112

Post up a picture, tell me they're £200, and when I can pick them up

The Octavia 18s will fit the golf no problem.

16s will also fit the vRS- that's the smallest size you can go and still clear the calipers. Tyre size should be 205/55/16. That's what size your spare will be if you have one.
They will look pap though, especially on the rear.
I use 17s for winter and changed the A3 ones I had for TT ones for this winter and they have a lower offset and they look better.
I'd suggest 17s may be a better compromise?
