Can't decide on tire size for 15x8
I bought a set of wheels for my new to me MSM. They are 15x8 ET+25. I have a problem in that I cannot decide what size tires to buy.
205/50R15
or
225/45R15
This car makes between 200-250 rwhp (much closer to the latter) and I don't plan on doing anything competitive with it, though I appreciate walking with a big stick if you know what I mean...
Halp?

GRM article in the December issue considered exactly this question. On track, the 205 and the 225 both delivered almost identical times on a 15x8 with Rivals. The 225 had a little more grip but steering response was better with the 205 because the sidewall was stiffer. A wash in the end according to Andy Hollis.
On a street car, you should probably do 225. It will give a better ride. The 205 falls outside the "lawyer-approved" range for a 15x8 wheel.

My wallet really likes the prices on 205s too. My neo gens have served me great through half a dozen track days and numerous street miles. At $63 a tire (I think), I can't complain. They were ~2 seconds slower than mobius's 225 rivals, both tested on my car on the same day, on a two mile, 1:34 lap.

TBH I am going to order a set of 15x9 6UL's whenever they are in stock again anyway so these are just a stopgap. I think I will just get a set of RT615's in 205 for now. Should be enough to tame the little tiny turbo.

I love my federal 595 rsr's, not saying they are amazing or anything compared so some of the more expensive rubber. But for the price they are hard to beat. Coming from shitty all seasons they blew my mind in the twisties.
