I've just brought a mk2 polo breadvan and need to no how wide wheels can i go on it thanks bill

5" with a sensible offset to be honest. 6" or so and you'll need to roll the lip back. Any more than that and it's arch pulling.

Any more than 7" and you'll be wanting arch reconstruction...

sorry to thread hi-jack but are gt steels with 165 65 13s gonna be ok?

I had rolled my arches but when I put the GT steels back on there was loads of gap left in the arch. I had that exact setup as well.

6" is really your limit if your not wanting to touch the arches much. Even then our gonna have to fold the lips in on themselves. make sure you keep an eye on offsets as well as they are extra important on a square. I had 13x6 ET30 wheels on my car and I had to pull the arches out quite a bit to make them fit, idealy you wanna stay as near to ET38 as you can.

depends on how you define go on. My mate ran 7-14 ET 26 RH Cups with 195/45-14 Dunlop with rolled arches

i dont really want to roll the arches yet
