Wheel and tyre size fit

[Polo GTEye N9]

Anyone know from experience what non VW ie Advanti 17x7 wheels and tyres 225/45/17 fit or too wide/high? Cheers Al

Would depend on the offset Al. But I do know that no one has managed to fit a 225/45R17 on a polo yet. I would suggest 215/40R17 as the biggest you can fit without fender work, but once again that would depend on the wheel offset

Hoyhoy.

I know that 225/45/16's fit.

What spec rims Eddy?

If you're lowered, 215 / 40's are all you want to play with without work. Even then, some plastic needs some rubbing to sit reasonably with stance at the rear.

Work to top-mounts can make a huge difference, but not a light undertaking.

And they would be a full 25mm less in diameter than 225/45r17 wouldn't they?

P.S. I'm running 225/45/16 (rims = 16 x 8 with 35mm offset) for the track which is a common semi size (but not in a road tyre) & is a lot smaller in height than the 215/45/17 & only 5mm higher than the 215/40/17.

Thanks for the replies and shared knowledge guys. Will not be going to attempt that size fitment. Cheers Al

Semi on topic, but what's the biggest tyre you can fit on stock rims?

what's the biggest tyre you can fit on stock rims?

That would depend on one's definition of biggest tyre, but as far as I can tell:

In terms of diameter, 235/80 R16 is the largest tyre that can be fitted on 6.5J x 16 wheels.

In terms of width, 255/70 R16 is the widest tyre that can be fitted on 6.5J x 16 wheels.

[rgvlee]

And for the non-literal interpretation what is the widest tyre you can fit on stock rims that will actually fit inside the guards on the polo


215?

[Diesel_vert]

205/45 R16 (which I realise is the factory fitted tyre) is the widest tyre that should be mounted on a 6.5J x 16 rim while keeping a 9N Polo GTI roadworthy.

215/45 R16, 215/40 R16 or 225/45 R16 tyres (listed in ascending order of section width) should be mounted on a 7.0J x 16 rim or wider. Mounting these tyres on a 6.5J x 16 rim would render the vehicle unroadworthy, but that's not to say they can't physically be mounted on a 6.5J x 16 rim, with the usual caveats (cash payment, no receipts, no records, etc).

[VWindahouse]

There was a larger wheel which was an option for the GTI, something like an Exor iirc which was 17x7 so you can go larger and be legal

[Diesel_vert]

Yes, one would ideally want a wider rim (whether they be 16" or 17" rims) in order to mount tyres wider than what the factory rims (6.5J x 16) would normally allow.
