I have a 05 6spd coupe with stock 245-40-19 on the rear.
I want to increase the width of the tire to 275/35/19.
Is anybody running this tire size on the stock 19's?

 

no, they're too wide for the stock rim.

 

How wide is the stock, rear rim?

 

^ the rear 19's are 19x8.5. the front is 19x8.

 

Then I will have to stick with the stock size?
For the front and rear?

 

That question has been asked many times, and explored to death. My answer is no, but other's disagree. My recommendation would be to use 255/40/19s in back and 245/35/19s in front.

Look here for another long thread.
