What's the correct 19" tire set up?
 

I''ve got a Performance model with the 225/45x18 stockers. I'm going with 19" ADR M-sports, 19x8.5 frt and 19x9.5 rear. I've seen people here with 245/35x19 frt, and 275/35x19 rear. I've also seen 285/35's.

From what I can see the stockers are 25.9" diameter. Toyo T1s 245/35's are 25.9" diameter. However their 275/35 are 26.5", a full 0.6" TALLER than the stockers. Won't this not only cause loss of acceleration and an inaccurate speedo? What am I missing here? I want w i d e r tires but isn't it important to maintain the OEM diamter? Help!!!

245/35 & 275/35 is the closest to stock that you will get ...

it is the optimal setup (assuming you don't have some 10.5"+ wheels inchers in the rear)

remember the rear stock tires are LARGER than the fronts OEM, 225 vs 245, so I think it is much less than .6"

just looked it up, stock 040 in 245 is 26.7" diameter, less than 26.5" (toyo)

Thanks for the info guys. I guess the 245 & 275 setup is the way to go. Now I have to find someone who stocks the Toyo T1's! :D
