Why so high?

Well as they say, "variety is the spice of life". Everyone has a different view on how to do things based on their personal experiences, what their dad always did, etc. But it is my understanding that the pressure rating on the sidewall is the maximum safe pressure the tire mfg recommends for that particular tire. The automobile mfg will list their recommended tire pressure on the door sticker. This supposedly is the best pressure to use based on the vehicles overall weight, weight distribution and handling characteristics. I believe my truck says to use 35 lbs. I assume this is just a "standard" to go by for all around or common everyday use, so I guess different conditions could warrant using a different pressure, higher or lower, within reason.

Unbeknownst to me, I took delivery of my truck with 45 lbs in each tire. I didnt check the tire pressure until I had driven it for about 6 weeks. I quickly dropped all of them down to 35 and fretted for a week or two that my mediocre gas milage might fall even further. Luckily that did not come to pass. I guess every tire has a range of pressures in which it can operate safely and efficiently. Even though I'm certain that tire mfgs include some "safety factor" in the max rec tire pressure they list on the sidewall, I personaly am uncomfortable testing that limit....GL to all...keep on truckin.

Over psi. is better than under. (My opinion). Less contact = less friction. Your looking for opperating temp. Go light if your checking it cold yankees. Sport bike wise they allways seem to play out on me down the center no matter what. I allways run em low. Partly cause when you get em up on the hiney they steer better. Something about the way the side wall crushes. Comes back around to the neww age tire idea. You seen what's happenin to the burgers Right? Think they ain't skimpin on this kind of meat. Oh hell no.

 Truck or bike, hard ones slide better.
