Tire size recommendations

Hi,
What Rims did you come across?
Not all Rims for these are clearanced the same for Brake Rotors or backspaced identically for the wheel-wells, but providing the Rims are for the 05’-09’ S197’s and you don’t go too far with width or run monster Calipers or brake rotors, you should be OK.

Originally, i was going to stagger width on my 2008’ GT with 19’s. To clear with no issues my staggered Tire/Rim target size was 255/40R19’s up front, 285/35R19’s out back. Tires...Nitto555G2’s.
I can assure you with a near stock GT you’ll have much improved traction on the Asphalt.
Lots of good tires out there, made for best performance under specific conditions..
A Physics law..”Friction is independent of surface area”. I have to remind myself of this.
For Tires, it holds a simple meaning:
..wider is not always better.
(Ok, I agree it does look pretty cool, lol.)
Have Tires in mind already?
A good resource to view S197’s with various Tire combo’s folks have already put together
on A.Muscle.
Best of luck!
