Wheel Offset

[Bernie]

This afternoon I finally got my Goodrich tyres, and fitted the wheels to the car, only to find that the front ones sit proud of the wheel arches by about 5mm either side.

This is a bit of a pig, as they are exactly as per Pilgrim spec, as discussed above. Not sure what to do now - they look good, but they aren't going to pass the SVA. Looking underneath, I reckon that where Pilgrim say -10 offset, the should say -20, though I suppose that could make the wheel hit the chassis. I could perhaps spread the wheel arch a bit, or maybe go to the SVA with the donor wheels.

As I know I'm not the first - what did everyone else do?

Is it the tyres or the wheel rims that sit proud of the wheel arches? The SVA test covers the actual wheels and not the tyres. If you have oversize tyres that are wider than the wheels it is not necessarily a fail point. I speak from experience as my Robin Hood failed on this point last year and the SVA tester explained what I had to do to rectify it.

If the tyre extends out further than the wheel arch, they measure it by holding a plumb line against the top edge of the tyre, then measure how far in it is to the wheel rim and to the wheel arch.

Thanks Daz

I did the bit with the plumb bob, and if I'm really accurate when I screw the front down, I think I'll be in by 1 or 2mm each side - thats if they haven't changed the rules by then.

I wonder about skimming the surface of the brake disc centres a bit - they seem to be quite fat, and don't help.

Given the number of Sumos, there must be more experiences out there...
