Well my tires are starting to look like they will be needing replacing soon. Right now I have Toyo proxes 245/45/17 and like them alot. I got them when I had about 15,000 miles on the car (car now has close to 50,000) due to the fact the stock goodyears were defective. I have 2 questions, I heard the biggest I coud go was a 255 tire on the stock rim. If thats true should I go with a 45 or 40 sidewall. Or should I keep the stock 245/45/17 size tire. And lastly what are some good tires that are price comparable to the stock goodyears and the toyo's I currently have.
