Hello I was wondering what the S.O.P. was for filling your tires back up after dirt riding? Do those little CO2 cartridges supply enough pressure or are they just kind of an emergency thing? Has anyone tried to use a small electric pump off the bike? If so what brand/model? Makes a world of difference letting out some pressure when hitting the dirt, but my favorite spot is miles away from the nearest gas station so I have to ride miles on half flat tires...which bites...any ideas, thanks Mark.

I once attended a tire seminar at a BMW rally by DUNLOP tires. The representative recommended using the recommended tire pressure of the motorcycle manufacturer. However, he stated to find the correct cold pressure, check tire pressure cold, then ride your motorcycle for at least 15-20 to warm the tires. Then, re check the tire pressure and if the pressure increased more than 3-4 pounds, the cold pressure was to low. In other words the tire pressure difference should never be 3-4 lbs. greater warm/hot than when the tire is cold. Also remember that the rear tire heating will be different from the front tire because the rear is driving or pushing the motorcycle forward therefore more friction/energy is changed to heat. for what it's worth - steve [Non-text portions of this message have been removed]

That's the best tip on tires I've ever gotten, Thanks! Marshall in Afton, Ok '95 KLXC3 "Blackhorse"

Yes, this fits in with the 10% increase limit I was taught. Andy Chesley Jennings, La. KLR & R11RA

Ok list here is the questions of the day: When checking tire pressure, are you suppose to (a) check before you go riding or (b) check after you have ridden and warmed up the tires? I have noticed that there is about a 3 to 4 psi difference in tire pressure when checking before riding and after riding. I am new to the world of duel sport and wasn't sure if there was any adverse effect running the tires low or high. Checkout Dual Sport News at http://www.dualsportnews.com Be part of the Adventure!

Low pressure on the street =tires get hot and wear out a hell of a lot faster than they should High pressure on the dirt = like riding on 2 rocks, tires don't grip for shit (sorry, that should read "doodoo") Think about ten speed bicycle tires vs. mountain bike tires.

I would generally do (a), since if the pressure is wrong then you'll know about it a lot sooner i.e. before it might make a difference to your safety.

There would be. Tyres generate heat from the flexing they do. Tubed tyres may make a bit more heat as the layers of tube and tyre flex against each other and create some more friction than you might get in a tubeless tyre. There is no harm in knowing what your warm tyre pressures are like. If you suspect a pressure problem out on the road, you don't need to sit around waiting for the tyres to cool off.

Ideally, you set the pressures for the conditions. RM goes into this in more detail in his post. Mister_T Melbourne Australia

I set my new Kenda's to 33 psi front and rear for the initial street break in. What kind of pressures do some of you use. I have used as low as 20 psi on logging roads and trails but I am not running rim locks. I was also running 33 psi on the street with my old IRC and found that they seemed to work fine on most gravel roads too at that pressure. I ride about half and half and would like to get at least 3500 out of the tire. Some of you have reported 5000 miles out of these Kendas, what pressures were you using.

Thomas, I have been using stock air pressure on the Kenda 270's.. apparently I should run higher on the street. In the dirt I am, as you, running around 20 psi... I di get 7k mi on the rear,,, on the first front and is wearing uneven, traed blocks that is. Dan P Graham WA.

I ran about 28F and 35R and got 5k out of the rear. The front is at 8k miles and still has tread left, but not much. For off-road, 20 and 20 is a good starting point.
