Bigger wheels and tyres

Post by PICKLEBRANTON »

Whats the maximum tyre wheel combination that can be fitted with a standard suspension height. I currently have 16" 7j rims and am guessing van 80 profile tyres. I am trying to achieve a better ratio as have a big engine that revs high

Ideally you want to match the factory diameter tyres so your speedo is accurate. VW fitted 185/82 14", so with a 16" height, 7" width wheel you can have a 205/60 16" tyre which is within a mm of factory dia. and I'll recommend 32psi & 34psi f/r tyre pressures.

Of course you could always fit 60 profile tyres on the front to keep the speedo honest and 80 profile on the back to improve the gearing.

Forgot to mention this is just to the rear so will not affect the speed reported. I was thinking of 80 profiles. Would that extra 20 mm cause an issue do you think? The back sits a bit lower than the front so this would level things out a bit

That's what ' have now all round and thought 80 at the back. Will I get clearance with 7j?

Sounds like I will get away with it. I could always get gas shocks if the back bottoms out. Should give me just over 10% better final ratio
