[V8] Tire Fitment

Tue Aug 3 02:05:41 EDT 2004

I have run 255/40-17's on 17x9 et 35 wheels without clearance issues.

Given the same wheel offset, here are some calculated dimensions...

nominal tire size | diameter | tire width | inboard increase | outboard increase
215/60-15 | 25.16 | 0 | 0 | 0
255/40-17 | 25.03 | 1.57 | 1.535 | 1.535
235/40-19 | 26.4 | .79 | .895 | .895
245/45-19 | 27.68 | 1.18 | 1.089 | 1.089

The two 19-inch tire sizes are .62 and 1.26 inches too tall,
respectively.  That latter one is fairly significant.   The
inboard/outboard increases in width are less than my 17's, but given
the extra height, the fitment will depend at least partially on tire
shoulder profile (shape), with wheel offset being a mandatory factor
to consider.
