120 psi on 26x 1 3/8" tires?
I need some new tires on the Sports, and happened upon the Bontrager T1's. My present (original?) Regency tires have a max. pressure of fifty-five psi. These new Bontragers have a psi of one hundred and twenty. What are your thoughts on running high-pressure on Westwood rims? Even if I preferred it, which I tend to doubt, would it be safe? Would it be safe to run 120 p.s.i. tires at 50 p.s.i (which I presently use)? I have taken the Sports on informal club rides with older riders, and the higher pressure would help me to get up the hills. I don't want a jarring ride quality, though. What is the thinking on these tires, and why are 26 x 1 3/8" (590) tires manufactured at road-tire psi?

I doubt the 26 x 1 3/8” version is rated at 120psi. (The 700C version, maybe.) I’ve never seen a 26 x 1 3/8” rim with hooked beads, which are needed for such a high pressure tire.

You are correct. Trek just confirmed that this size is rated from 70-100 psi. That still sounds a little bit strange for a 3-speed, though. I am not understanding what kind of bike this tire is designed for.

But - tubed clincher wasn't a choice? I don't think I am the only one who still riders them. (Should I run out and buy a lifetime supply of tubes? A nitrogen gas filled freezer?))

There are tandems and perhaps loaded tourers riding on 26x1-3/8" tires, somebody had to make tires suitable for them!
Indicates a strong tire casing, so likely durable.

I skipped the Bontragers and committed to some N.O.S. vintage 590's, which are Michelin, made in England white-walls. I just did not want a harsh, high-pressure ride. Thanks for the suggestions, Jeff and Surfer.
