I am in need of some new tires. It's a dd. I need an all around good tire. I need a little traction in summer and I need a little bit of traction in the winter, and wet conditions included. Did I also mention that I am cheap? Sears has some Bridgestone Superguard assurity for a good price and I was wanting to know if any of you guys have had heard of used them. The size is 245/50/R16 Is this an ok size to use. Anyone with some suggestions? Thanks
