Tire Pressure - CyldesdalesDavidK

I weigh over 200lbs and wonder what all of you other bigger riders are doing as far as tire pressure is concerned. It seems that we need to run our tires at a higher psi as compared to smaller riders. For instance, if I try to run my tires at 40 or so I find that they bottom out to the rim. Thanks. DK

40 PSI sounds a bit low for a Clyde running clinchers. I weigh about 210 and have been running about 55 PSI. I haven't had any pinch flats, but I have bottomed out my michelins on some bigger roots.

I like to run my tires as low as I can get away with without pinch flatting. I'll raise the pressure on really rough stuff to keep from pinching, or if it's a really smooth course.

It'll depend alot on your riding style, terrain, and what size tires your running.

The last race I did was a bumpy course but didn't have any rocks or roots. I didn't bottom the tire at all while riding, but did a few times on my less than gracefull remounts later in the race as I got tired.

yes, 55 psi is a good starting point. I'm 230+ and run anywhere from 50 to 75 psi depending on terrain. yes at anything in the 40's you'll feel the rim bottom and pinch flats are common. It's a sad fact of life that most cyclist just don't get. So we ride with less traction to fight flatting. Also try to pick as smooth a line as possible and you may get to lower your pressure

215lbs. running 45-50psi, no pinch flats yet, too soon to tell if the foam is of any benefit or just marketing.
