Thanks you guys for setting me straight. I always thought it was
in millimeters, I didn't realize it was a ratio. I guess that's why
offsets always confuse me and I always have to look at the diagrams
to make sure I get it.
For the record and for better or for worse (OK - worse, much worse),
I'm currently running 215/45/17s. The rims are 7inches wide
and I'm not happy with the steering characteristics at all so
I'll be looking for 17s by 7.5 or 8 (preferably 8 - can you say Boleros :)?)
and will look to run 235/45 as I think it is the narrowness of
the tire combined with the weight of the car that is screwing up the
I've found that while I love my V8Q, the steering in particular is much
more luxury than performance - more play in the wheel and I can drive it
with my pinky.
