Hi, I've searched the threads and seen a lot of discussion regarding tires, but nothing regarding pressure. I'm running Kenda 270's on front and rear. The KLR recommended pressure is 21 psi for both front and rear. The Kenda max load pressure is 33 for front and 40 for rear. Riding mostly on roads but getting out onto the occasional jeep trail. Do you suggest that the KLR recommendation be followed or the tire manufacturer? Or somewhere in between?
