Evening all,

A quick question.

Whilst searching the threads I found conflicting information on the uk spec wheel offsets.

One stated : Front 35 and Rear 45.

 

The other : Front 45 and rear 35.

 

Can any one tell me without doubt which is correct?

 

 

Many thanks.

1st one mate, however you can move away from those figures a bit and when getting BIG wheels and wide, the offsets can be a lot different.

Thanks,

I have seen the offset calculating tool which is most useful for working out wheel sizes http://marksink.com/tire_wheel_offset/offset.html.

 

What would be a good bit of additional knowledge to go with this for Zeders would be :-

 

Given standard offsets front and rear and a car that still has Hicas engaged.

 

How much clearance remains before a wheel will foul or how much wider can a wheel be before it will foul.

 

Two clearance dimensions needed for the front and two for the back. One clearance dimension for wheel to wheel arch (outboard) and the other for wheel to running gear (inboard).

This information coupled with the offset calculator would help to get the fit right.

 

Personally I am looking at fitting 18" rims and following Legraths guide of an 8.5" front with a 235 35 tyre and 9.5" rear with 265 30 tyre. I wonder though, when I get to a wheel shop how restricted I am going to be by offset, width etc and this is where I believe clearances and the calculator will come into their own.

So if anyone has any figures please post them.
