Marietta, GA | Hi All
I'm a relativly new rider and i see people talkinng about the difference between 38 and 40 pounds in the tires. being a new rider, what difference is there with 2 pounds, what effects can be seen by varying the pressure? i know in a car, it affect tire wear, but i'm assuming on a bike it has to do with handling.
thanks,

Central Maryland | Your tires will last longer with 40psi |

Green Bay, WI United States | I agree with willtell but there are so many factors involved with tire pressure and also rear shock pressure. They go hand and hand, especially if your two up. I ride regularly two up and the 40 PSI pressure is what I run front and rear but still have to adjust the shock PSI, not sure why but I can have the same air pressure and have a bottom out situation and the next ride do nothing with the shock pressure and do not experience any bottoming out. Her weight does not change that much (did I just say that?). I have never had tire problems other than a whine in the corners when they need to be replaced and I have that now. Hope this helps and as I always say;

| tire pressure grows with riding heat. You get more life if you run 40psi. Buy a good gauge and in summer months check the first of the month and when it gets really hot 95 plus check twice a week. You'll find tires loose about 3 to 4 pounds in that length of time. Yes its a pain but when you get 15 thousand plus and tires coasting over $200 the checking pays off.

New Mexico | I can feel a 2lb difference in handling, so try to keep it pretty tight.
This last summer I installed a Duran TPMS and am very happy with it.

I don't have the tire monitor but no doubt you can feel the difference in handling. |

New Bohemia, VA | Check the tire pressure cold, 40-41psi is what you want. Hot, it will increase to 45psi or more, do not adjust. I can tell the difference if the tire pressure goes below 40. |

| I also have a TPMS and keep my tires religiously aired (cold) to 38 front, 41 rear. I get around 16k between tire changes at those pressures. My belief is that for every 1 psi you are low, you lose about 1k of tire life.
And tire pressure can change daily, especially with changes in ambient air temperatures between seasons!
I also ended up changing my air compressor's tire chuck for one with a center that 'catches' the tire valve core instead of the ones that tend to push if off to the side. The standard tire chucks have a tendency to bend the tire valve core, which can allow it to catch the side of the valve, and not seal completely.
Keep an eye on your valve core and make sure it's not bent. If it is bent, they are cheap to replace....
