The best I can do is, hope that someone didn't park on the ends and lock my bike up to that. Fat bikes aren't for everyone, that's for sure. I'm debating about when I get my next set of rubber, that I go with a 26"x3.5".
I'm almost positive that when I parked on the end, once at work. Someone thought I was just being a jerk and let out the air in my rear tire. Jerks. I pumped up the tire (arm is still sore two days later) and I haven't had any issues with it.
- Be mindful where you park.
