I need some advice. I REALLY need new tires, and I was thinking of hanging on to the ones I have which are tiny and look so stupid, until october so I could buy studded ones, then regular tires in the spring. I was thinking I dont want to get new tires incase something happens to my Jeep in the winter and I'm stuck with a set of tires I dont need. I was going to get 31x10.5x15 tires. Is it worth it?
