Tire pressure?
on: August 27, 2020, 02:29:23 AM
My riding is a true 50/50 mix of gravel and pavement. My other bikes with tube tires I usually run a lower air pressure for the gravel. My 2020 500X is my first experience with tubeless tires and I'm wondering how low can I safely go with air pressure? I've  been experimenting lowering pressure down from the 29 / 41, I'm now down to 24 / 36.

Your good with those pressures-but don't forget with the skinny front tire if you lower it to much and hit a hole or good size bump you could bend the rim-seen it happen many time including myself

If you're regularly riding on unsurfaced roads and trails, you'll benefit from lowering the rear further still to improve grip and traction...

for info. I run 28psi front and rear all the time (with TKC80 tyres) both on and off road/mixed terrain riding - maybe dropping them to 25psi if things are particularly soft or rocky.

I wouldn't go much below that (as Motorboy suggests) to protect your rims, and to keep tubeless tyres seated - certainly no lower than 20psi in that regard.

totally agree: 30-28psi all the time, sometimes as low as 25 at the rear. I learned it the hard way !!!!

Thanks everyone for your thoughts and experience  :763: I think I'm going to leave the front at 24psi and my next ride drop the rear to 32psi.
