[urq] tire/wheel size

[Ingo Rautenberg]

Brandon,

I'll chime in.  When I bought my first V8 with those same wheels it came
with 205/65 15 tires instead of the called-for 215/60 15 ones. And, no, they
weren't too narrow.  Actually rode very smoothly.  I don't think you'd have
any problem running those tires on those wheels.  Think about it.  Audi OEM
for the Ronal 15x8 wheels used 215/50 series tires.  205's have a 10mm
smaller section width = 0.4"  and your 7.5" width wheel is 0.5" smaller.
You'll be fine 8-)

Ingo
