Tire pressures
« on: July 04, 2019, 02:19:20 AM »
Z Force 800 EX 2018, just fitted 27-9-R14 and 27-11-R14 CST/Maxxis Behemoth 8pr.
Any views on tire pressures, bearing in mind these are radials speed rated at 130 kmh,
CST state on their specification 22 psi, seems a bit hard maybe ok for the road.
I am riding on Hard pack, loose over hard and some bits rocky, from what I have seen on
promotional videos its looks very much like you guys have on your west coast.
I´m looking for a suitable pressure for this kind of terrain we do very little rock crawling at
low speed its nearly all fast trails at mid to higher speeds.
Any of you guys have experience with this kind of tire on this terrain ???

Never over 12psi. Mostly between 7 and 9 psi. I run between 7 and 8 on my Reapers and they are 27" 8ply radials. Run a little higher on rocky stuff to help stop sidewall pinching. Less on regular trails and mud. Most tires fit these CFM wheels looser on the beads then other wheels so don't go under 7 otherwise you can pop a bead just making a hard corner sometimes. Now if you do a lot of asphalt driving stay around 9-10. It will help with wear.

My Wanda tires are stiffer than stock but I run 6 in front and 7-8 in back and this is a good compromise. I find the maker's recommended 10 and 14 to be crazy hard and I suspect it's more CF Moto's way of helping boost up their rather poor stock ground clearance.
22 is insane, book a dental appointment in advance.
