My wife and I are close to getting a new MX, just working out a few things yet, (insurance, etc). One item I have been trying to get clear(er) answers on is tire life. I've reading forums all over, and some users are replacing in 10k miles or less, while others say they get 35k more. I know weather, and driving habits influence this answer a lot, but we do not worry about snow in Florida, just extreme heat, and neither one of us is speeders, so we won't be drag racing around town. We also both work from home, so no long daily commutes either. What is there best (20 inch) tires to use on an MX and should I be worried about dropping 1k per year into tires.
