the french manual says 1.25 kg front and 1.75 kg rear, for a mixt use.

But for a dirt use, a enduro use, i would put 1.5 kg or less 1.00 kg.

what do you think about this?

thanks

PostSubject: MT21 Tire Pressure   Thu Aug 22, 2013 11:31 am

nahoj,

I'm running an MT21 on the front (MT 43 on rear), I comfortably air down to 14-16 PSI (0.98 to 1.12kg) for aggressive off road riding so your are in the right range. FWIW I run the MT43 at about 10-12 PSI (0.7 to 0.84kg) off road.

The one issue that I run into is aggressive and non linear wear of the center knobs when I'm running low pressure and riding on the street. I don't trailer my bike anywhere so getting to the trails always means some amount of road riding - I'm trying to get in the habit of airing up for the tarmac, down when I hit the dirt then hand pumping back up for the ride home.

Good luck and have fun!

Joe

Depends on whether you have rim locks. Without rim locks, I always stay above 15 psi, which works well for pavement and mixed use. With rim locks, I run 8 to 12 psi for dirt and they still work OK on pavement.

Yes, dhally makes a great point! I forgot to mention that I'm using rim locks front and rear and agree that going too low without them would not be wise thumb
