Square setup

[Cheesypuff]

Hi, could a tyre expert suggest tyre sizes for an 18" x 8.5 square setup please? I haven't got the foggiest

I just searched 'square setup' and there are quite a few results.

 

Are you wanting a square setup on the tyres or staggered?

[Cheesypuff]

Well the wheels will be a square setup 8.5 all round. As the oem six spoke wheels are also a square setup 8.0 all round but are fitted with wider tyres on the rear than the front I thought that would be the way to go, is that right?

[Stew]

People have done both hence me asking.

 

I guess ultimately tyre size would come down to how you want the car to look and how aggressive the offsets are.

[Cheesypuff]

Offsets are 30 all round, maybe fitting spacers later. I just want to keep as close to standard as possible really.

[Stew]

With 8.5s and 30 offsets you'll need spacers.

 

I always feel that if you are changing wheels then you might aswell get it right first time.

Nothing wrong with having a square setup with your wheels, but you MUST keep the stagger between front and rear else you'll end up with a horribly oversteery car that's going to try and kill you at every attempt. Keep it a minimum of 20mm like stock is (i.e. 225/45/18 and 245/45/18), or increase the rear size if you want more grip at the rear.

That's answered my question thanks.

I hope there's still some owners here who care about handling

Not that dramatic and going too wide will result in understeer. A few combinations here:
