In my ongoing quest for the "most proper" tire application for my upcoming particular setup, I have heard from various members here that a 9' wheel will accomodate up to a 275mm! Now after checking on various brands and their application charts, I have noticed that most manufactures are calling for no smaller than a 9.5 in. wheel & up when the tire is a "30" series (275/30/19) but if you go up on the aspect ratio to 35, then they list a 9' in. as able to work?! Now the reason this is obviously ($$$) a concern is that after narrowing down my dimension range there are only two brands I'm interested in! Ironically they offer slightly different sizing. So after painstaking research my 2 options are:

1. 235/35/19 Front & 265/30/19 Rear (280 treadwear!)

2. 245/40/19 Front & 275/35/19 Rear (220 treadwear)

Both of my choices have AA traction and are Max Performance!

Option two is the way to go.... 235/35/19 is EXTREMELY low profile. Also, it will not fill your wheel well ANY more than it is with your current 17" set-up using your existing suspension....
Actually, using option 1, the rear wheel well gap would increase by 1.25mm(NOT noticable to the eye)
Read the following and pay special attn. to the "radius" measurements. Radius is the distance from the very center of the wheel to the very edge(including tire)
Option 2 means that your fronts will fill the wheel well .35"(almost 1/2") more, and the car will be raised .35"(almost 1/2") higher. Again, not very noticable to the eye but easier on the wheel, a little more clearance, and no sacrifice in performance. Your rears will fill the wheel well .3"(8.3mm) more and the car will be raised .3"(8.3mm).
My 20's will fill my wheel wells EXACTLY 1/2"(12.5mm) more and raise the car EXACTLY 1/2"(12.5mm) more than the 18" SSR did using 245/40/18, and 265/35/18.
Dont forget how small a mm is...Having your fender gap as small as possible will offset any small change in the height of the car.....Tiny
