These will be for the street.
My 15x8's are for track tires.
And no I won't buy another set of wheels.

225 pros:
- meaty!

205 pros:
- $45 cheaper

edit: they're the same weight

Would 225's on 15x7's corner harder?
Would they feel/handle funny due to the narrow rim?
Would the sidewalls look funny?
Would 225's camber-wear faster?

Tirerack specs say 7.5" rim is standard for 225's,
- allowable range is 7-8.5".
- (for 205's it's 5.5-7.5", 6.5" standard)

 

205

 

I just received my 205 Rivals today. Going on 15 x 7's

 

225's would also ride softer/comfier

but I'd still get the 205's because they'll be fine, be cheaper, and be lighter

 

They aren't lighter, Jason was looking at the wrong line in the Tire Rack specs. The 225s and 205s are both spec'd at 20 lbs. The price difference is also $11/tire, not $45.

$11x4 = $44, round up to $45 for the set.

 

Jason was accidentally looking at the 225/50R16s, not the 225/45R15s.

No comments on differences in feel and cornering grip?

 

They'll both grip about the same, but squeezing 225s on a 7" wheel won't have as sharp of a turn-in feel as the 205.
