He easily weights 400 (probably 500) pounds. The problem is that his leg muscles are really weak so when he goes over any sort of bump in the road he can't get out of the saddle and let his legs absorb the shock so inevitably gets a pinched flat. He's gotten a pinched flat each time he's gone for a ride as he's not exactly nimble on this bike.

So what are the options? He's tried upto 32mm tires and they didn't work as the inflate upto 85PSI and even the Serfas Seca's which go upto 120PSI (in a 25mm) didn't work.

Any other suggestions? Is there some sort of tire liner he could use? The guy is really trying and I want to help him out.

On a related question, his weak legs means that at the end of a ride he can barely get of the bike let alone stand up. Not sure if its a circulation problem or something else.
