Not to mention "pinch" flats. I never go less than 15 - 18 psi and can see no reason to. With a big heavy bike and a big heavy hunk of strapping stud (me) on the KLR, I reckon you'd be flattening tires at lower psi. CA Stu

Stu- I would disagree... It depends on the sidewall of the tire that you're running. I would not go below 15psi on a Kenda K270 (especially in the front) but on my Gripsters I went well below 5 psi w/o any flats. The sidewalls on the gripsters are much stiffer and thicker than the Kenda's and I don't have any reservations about running them that low (sometimes you need to when it gets hairy on those tires). Just look at the run-flat tires, most incorporate a super stiff reinforced sidewall to support the car and prevent rim damage. Though not exactly analagous to our situation, I think it does illustrate the role that sidewall stiffness/toughness plays in preventing flats. Zack

any lower and rim locks come into play. I've run as low as 10psi measured with a shitty guage so it may have been lower. Didn't use rim-locks didn't have a problem. Not saying you couldn't but I didn't. A pretty good enduro rider (AA class for those who care) I know says the other trick is to take the nut off of the valve stem so if the tire does spin on the rim, it doesn't necessarily have to be catastrophic to your tube or to your day's riding pleasure. dat brooklyn bum

How many rim locks do you have in the wheel?  Changing a tire with one rim lock is easy, two rim locks presents other problems but can be done.  I usually start and end at the valve stem to install a tire.  I treat a tire change with a rim lock included the same way.  You should check your rim tape anytime you have a tire off but pay attention to where the rim lock was to see that the rim tape hasn t damaged the rim tape.  Watch that the tire bead goes under the rim lock and not over the top.  That happens and makes seating the bead impossible or very difficult.  You also need to watch that the tube isn t under the rim lock so it doesn t get pinched when you tighten down the rim lock.  Once the tire is installed, I always inflate the tube to seat the bead, then I deflate the tube to relax the tube and then re-inflate it again.  I tighten the rim lock and snug the nut on the valve stem after I check the air pressure.  You can install the washer and nut or nuts on the tube how you like and they will probably work.  The order that most new tubes come from the factory is: tube, cupped washer, first nut, rim, and last second nut if you have one.  If you want too use only one nut, it can go either inside or outside.  Honda and some other dirt bikes use a large hole in the rim to allow movement of the valve stem when you run low air pressure.  They also use a rubber seal over this hole to keep out the muck that we all run through.   Now if you have two rim locks, the installation procedure is completely different.  Let us know what you got.
