215/45-17 on a 7x17 rim... WRX
225/45-17 on a 7.5x17 rim... STi '01-'04 JDM and USA
225/45-17 on a 8x17 rim... STi '05-'06 USA
235/45-17 on a 8x17 rim... STi '05-'06 JDM
235/45-17 on a 8x17 rim... EVO

This is the common thinking on rim width and tire width. These are all Factory spec.

dbarnblatt, that list is spot on. If all you're ever going to run is 225/45-17, there is no reason to get 17x8 wheels vs 17x7.5, unless you like the stretched look.

The '05-06 STI (with 8" wheels) has the unusually wide RE070, which is 235mm wide, despite the number printed on the sidewall, so that is a bit of an exception.

The 225 won't look stretched on an 8" rim depending on the tire.

Here is a pick of my old setup. 8" rims 225 45 17 ES100's. Straight sidewalls, no streching. I gaurantee my 225 45 17 ST215's would not looked stretched on an 8" wheel.

Oh, I'll play:

-wagon w/ rolled fenders
-Prodrive springs
-about -1.5 F/R
-Falken (FK451)
-17x7.5, ET48

I need help deciding between 235/40 and 235/45. I think I may bend a rim with the short sidewall of the 235/40 and the car is street-bound except very infrequent HPDE or autox.

Don't mean to hijack--only to supplement.

All of these are part of the "simple" answer you want.
With a 17x8 wheel, What kind of setup would facilitate the widest possible tire?

And what are the side effects of going with the widest possible tire/wheel? (possibly 8.5 to 9 in. wheels also).

Maybe Hankook's marketing plan is putting big numbers on narrow tires???

.....my 235/40 hankooks were a bit wider than the 225/45 falken 215's that they replaced....

....and the rpf-1's in 17x8 would be a great choice for a wrx

Black to reality.


Dude! If you can get the 8" wide rims with 235's (either 40 or 45's) do it! You can way tell the difference between 7.5 and 8 when using the wider tires. Way more grip, way more stable. I've been running RA1's in 235/40-17's on 8" wide torques at the track (on my wagon) and it ownes! Some of the time I leave the RA1/Torque combo on and run in the street for a few weeks if I get lazy. Then when I switch back to my street tires which are 225/45-17 on 7.5" wide torques the car just feel squirley for a few days until I get use to driving the narrower tires and rims again. I couldn't believe the difference. The one thing I can't tell is the difference in the weight.
