How much tire pressure?

[aicabsolut]

I've ridden those Specialized tires. I also recommend 120psi. Closer to 100 and I got pinch flats.

Even though I'm light, I like the handling of a firm road tire, and I don't notice the supposedly rougher ride. I race on my Michelins at 110psi, even in the wet.

This is what I posted in that other thread:

Tire Width=20: Pressure(psi) = 0.33 * Rider Weight in lbs + 63.33
Tire Width=23: Pressure(psi) = 0.33 * Rider Weight in lbs + 53.33
Tire Width=25: Pressure(psi) = 0.33 * Rider Weight in lbs + 43.33
Tire Width=28: Pressure(psi) = 0.33 * Rider Weight in lbs + 33.33

I always inflate the tires to the max pressure allowed, and never had a problem.
If they are underinflated you run the risk of getting way more flats.

Thank you all VERY much for your input. Your advice is much appreciated.

Happy cycling!

I think I remember someone saying to do this because it makes the bumps a bit gentler on the hands. But I don't know the science behind two wheels with different levels of rolling friction.

I keep my front wheel slightly under-inflated compared to the rear for exactly that reason. I was having a lot of issues with my hands, and this really helped for me.
