Thanks for the responses. I think more aggressive riding definitely has something to do with it. As far as I know we just have plain ol' gas year around, no ethanol, so I don't think that's a factor, but I could be wrong. I just checked the tires a few weeks ago, but it's gotten colder since then, maybe it's time to check 'em again. Although I just had a flat fixed up front so that one should be correctly inflated. Guess it's time to back off the throttle and ride like I drive my truck - like an old lady!
