My car came with the 19" wheels and I have my eyes on a set of aftermarket 20s.
I'd really like the added protection of a thicker tire. I also think it looks better. I want to know if I will run into any problems if I ran a 245/40 and 275/35 combo.
I've read conflicting information on this forum and can't seem to get a solid answer. Anyone out there running this tire size? Anyone with some real answers?

Not sure if you have tried this. ut they do offer tire size estimator apps. The one i use is car calculator app.
Its nice to use so you can calculate the correct ratio front and back. the last thing that you would want to have is the front wheels turning at a different rotation and the back and hurt the driveline of the car.
