Well I picked up a set of LR3 18" wheels to mount a set of tires to run in the winter. I was all set to get a pair of the coopers and then read that you cant run chains on them for lack of clearance. Where I live we have some short but very steep hills that I have always needed chains to get up when it snows a lot as well as when we have much ice. Also when going up to the mountain skiing, I have been required to have chains on (only once but now I know it can happen). Anyway I have read that you can run chains up to a 265-60-18 (30.5") but am wondering if they would go on a 275-60-18 (31"). Or is there a way to run them on the coopers? What if I raise the ride height all the way up? I really only drive this one on pavement. Thanks for the help or any suggestions.
