Now correct me if I am wrong... the first number is how tall the tire is,the second number is how wide it is and the third number is the rim size.
If I am correct, I have 265/70/16 now,but don't want to get new rims( in fact I LOVE the stock rims that came with my SR5) nor do I want wider tires. So I should probably want to go to maybe a 270 0r 275 tire? I thought I read somewhere that I could go to a 32" tire max without any issues,but I am not sure if they were addressing a newer Tundra or my year.My game plan is to buy the tires from a place like Tire Rack,but of course if I do that,I can't test to see what size would fit without any issues. This is why I am doing my homework and asking folks who know much more than I do.
