Wait a second - the tire print says "maximum cold inflation pressure 44 psi" (or words to that effect). Now they wouldn't say inflation and cold if it was not ment to indicate while operating on the vehicle just like the maximum load weight (at the max pressure).

well I'd imagine they're right about them taking 100 or so PSI... because they have to take 30-40ish plus survive knocks. I don't know what the hell they were on about for the max sidewall pressure though.
by the way, was on a long summer highway trip once, pulled off for food, checked the tire pressures, read 50 psi, when they were inflated to 36 psi cold, nearly went and let pressure out..doh!.. after we had eaten .. checked them again and they were down to 40.. |
My car owners manual, and my motorcycle manual both recommend increasing the tire pressure for any kind of high speed, or extended distance travel, a 4-5psi increase seems to be most common.
I have never had any issue at all with running 50psi, dead even tire wear, awesome traction in snow and rain, I replaced a pair last fall after running over a bunch of hard ware that was on the road poking a 3 holes, two nail holes and a good quarter inch hole thru my tire at 50psi, plugged it and added some sealant and drove another 2,000 miles with it again at 50psi before getting the tire replaced. |
Every time you hit a bump or pothole, the tire pressure spikes. Overinflation may bring the tire somewhat closer to its bursting pressure, but if that were really a problem, we'd surely have heard about that here.
That said, tires can burst from overheating, in extreme cases. Hard braking makes heat that is transferred to the tires. Surely more a problem for jet aircraft and racing cars than economy cars. |
The only problem I ever had with this is when my girlfriend gave me a Mazda 323 when I lived in Hawai'i. The car was in okay shape, and ran great. I have no idea how old the tires were, but within weeks of overinflating the tires to less than sidewall max, 3 of them seperated (I mean the tread form the rest). You may ask why I didn't deflate them to norm... I wanted to replace them, anyway, and did experiments with different pressure.

but yes, tires are the things that absorb most of the bumps in the roads, the shocks just keep the tires on the ground and to keep the car from boucing up and down after a bump. now if you think about it for about 12 micro seconds if thje tires are stiffer than factory now, then the energy absorbtion is now beign doen by the ball joints and cv axels and whatnot, which isnt what their designed to do and COULD wear out prematurely if the car has cappy ball joints, etc. but yes usualyl factory specs are low to make the ride seem comfy so id bump em up a bit but not too crazy |
