Hi

I am after some replacement alloys for my cab and need some help with alloy\tyre sizes.

I want to go down the 16"\17" route and need to know the maximum width on rear as I don't want to change suspension or roll arches etc, can anyone help?

Thanks
Naz

Don't put 17s on, bmw, alpina, hartge, racing dynamics and Schnitzer used up to 16s for a good reason.

I'm pretty sure 205 and 225 are the max width for 7.5 and 8" rear wheels.

17s will give horrible ride quality.
If it ain't broke, fix it till it is

Thanks for the replies guys, I have been offered some 16" alloys with a 9J rear together with a 195/45/16 stretch, would this be OK?

I have 17" at the moment and they are not too bad, but obviously if I can get a better ride with 16s then I may go down this route...

No, stretching tyres is stupid.

Should be okay depending on the ET of the wheels :)

The ET is 20, they are a staggered setup as the front rims are 7J and the rears 9J....?
