Johan A Marais Posted March 1, 2009 Posted March 1, 2009 Currently I am on Kenda Nevada's on my MTB. Tubeless... I need to know the correct pressure to ride these on in sandy, rocky and wet conditions. Do I have the back and front on the same pressure or will the back always be harder than the front? I weight plus/minus 74kgs on a good week Currently I am on 2.5 bar on the front and 3.0 bar on the back.
turtlek Posted March 1, 2009 Posted March 1, 2009 Moonman i weigh 60 so there is a bit of a weight difference but i found that riding 1.8 on the front and 2.2 at the back is perfect for me i could suggest going a bit less on both but also play around and find that pressure that works for you, if you start too high you will slide around corners instead of turning round them and if they are too soft your tire will roll off P.S. What is a bad week?????
Johan A Marais Posted March 1, 2009 Author Posted March 1, 2009 Mmmmmm - Thanks, the slipping and sliding is what happened today and the track was very sandy and loose.Again rider A130 suggested that I am riding on to much tyre pressure...
turtlek Posted March 1, 2009 Posted March 1, 2009 sandy courses i go less in front but slightly more on the back but in general i keep my pressures about the same a nice benchmark is that when you sit on your bike there should be a decent bulge ast the bottom of your tire but not so much that it feels spongy
Gert Janse v Rensburg Posted March 1, 2009 Posted March 1, 2009 1,8 back and 1,7 front..... RaceKing tubeless and MountainKing respectively.... did sani like this...... I weigh 58kgs.... works a charm for me....
thatcap Posted March 1, 2009 Posted March 1, 2009 your best performance is gonna be 28psi front, 30psi rear. i weigh 74 and thats the pressure i run.
Johan A Marais Posted March 1, 2009 Author Posted March 1, 2009 Thanks hubbers, some good feedback here... The end result is that I need to drop it slightly and see how it goes then. Yours in Cycling!!
KlapperKnop Posted March 1, 2009 Posted March 1, 2009 ZIPP has a very nice chart according to your weight .... for road racing, the front has less pressure than the rear .... KlapperKnop2009-03-01 12:31:26
TYGA Posted March 2, 2009 Posted March 2, 2009 If you ride rocky often make sure you don't ride your tires so soft that you end up damaging your rims. I was marvelling at how great tubeless was and how you could crank across rocks without getting pinchflats but when I changed tires I noticed quite a few dings in my rear rim.
MTB Hout Bay Posted March 5, 2009 Posted March 5, 2009 I weigh 90kg and ride Kenda Nevada front & Kenda Small Block 8 on the back. I mostly use 2.0 bars on the front & 2.2 on the back for most conditions. I'll only go harder if the terrain is less technical with more road for better rolling resistance.

I weigh 81kg's and also use 2bar in front and 2.2 bar at the back. works in all conditions. I suppose 1.8 and 2 bar could work for someone as light as 72kg's
