My insurance companies says I can have rims up to 8 inchs wide aslong as they have a 0-5mm positive offset. Can anyone help me on this one?

It's the increase in width "center to center" of the rims.

MrT

How do I find out what rim have what offset?

The manufacturer/supplier should be able to provide this info. You could measure them if you have access to them or it might be stamped or cast on the backside of the wheel somewhere.

The insurer is specifying this so that your track remains legal I assume. +ve offset rims place the wheels further under the car (reducing track width) while -ve offset rims place the wheels out further (increasing track width)

Do you know if the a factory rim would be within this limit? such as the 16inch el/ef xr8 rims?

Thanks for your help

Sorry no I don't. But if your using optional wheels available from Ford on a car with the same basic suspension I don't see how they can justify knocking it back.......they are an insurance company though

I was under the impression that a zero offset rim was one having equal width either side of the parting face at the brake. Therefore negative offset has more rim inside this line and positive offset has more rim outside this line. As track width is measured from centre of wheel to centre of wheel, it's more important to stay close to the offset of the factory fitted wheel. ie if your rim is 1 inch wider, you want 1/2 an inch inside and 1/2 an inch outside the original rim. (if possible).
