This is basically a copy from my post to the front tube. These are great on my Honda CRF250R. Install was a breeze and I know these can take a beating. I am a heavy rider so casing jumps and hard landings can be tough on my wheels, but I never have to worry with the heavy duty tubes and my big butt now. They are running strong and will continue throughout the rest of the year. I run them around 11 to 13 PSI based on track conditions. Also, I always change out my tubes when I put on new tires, just a good habit to get into because they wont last forever. Bridgestone and Motosport.com probably love me for that, lol. Recommended!
