I do the same as [MENTION=227213]wphamilton[/MENTION]. A daily spot check on each. I keep my eye on the front at stops. I try to do a thorough look over every few weeks.

That being said I just went out and did a full check.I was paranoid something was wrong and the thread reminded me I wanted to check.

After the puncture I got last week I want to ensure no problems happen. It was a big hole and I used a duct tape boot. It was the rear and could stand to be replaced after the hole.

I have never worn an adult bike to the threads. I have had more problems with sidewalls on my schwalbe failing. So I am vigilant about checking them.
