Thanks for sharing your unfortunate experience. I’ll take my own advise more seriously now.

I think the gains are pretty marginal but they do give a little benefit, which is useful if racing. It also depends on the type of cycling. Time trialling on smooth roads benefits from higher PSI. In track cycling, the tubulars may go up to 200PSI. I’m sure the top track Cycling teams have researched benefits of high PSI.

However, for road racing, you wouldn’t want such a high PSI as you will get better cornering at 90PSI than 150PSI

I have experienced inflating tyres to their max and then leaving the bike in full sun for a few moments, and the tyre exploding. So I would go along with not leaving the bike in a hot car.

Is there any reason why you pump your tubulars up to 160psi? I’ve read on a number of websites that inflating them that high doesn’t have any benefit, and if anything just makes the ride more uncomfortable. I’d be interested in knowing your reasoning behind it, I find at 100psi mine perform fine.

Long fast descents eg Col du Glandon can heat up the rims, and if your pressure its too high, can cause them to pop. Lots of riders on the Marmotte find this out every year, and have broken bones to prove it.

I always ride at 80psi unless I’m racing. 80psi is fine, and I’ve been puncture-free for 3 years.
