I don't disagree as those recommendations apply to original equipment tires.I always recommend the following the vehicle information placard recommendations.
My recommended pressures (per the owner's manual) is 30 psi front & rear for normal use. For sustained high speeds (130 mph) it goes to 32 front and 34 rear. The maximum tire pressure cold for the OEM tires, which were the F1 Supercar EMTS was 41 pounds. I believe the 30 psi base recommendation WAS NOT focused on a soft ride, because the tread wore out in the middle first when I ran 30 psi, which the signature of an over inflated tire.Forum,
Thanks for all the feedback so far. Another follow-up - Does anyone know if tires sold in Australia have different pressure ratings than those in the US - or if they at least have different numbers stamped on them?
I guess the question is - is the `32 PSI thing an American specific pressure geared towards a certain plush ride?
What I've learned so far is that my run flats with 29 psi cold should be pumped up about 4 or 5 psi and then tested for ride/performance. With the temps around 100 lately I'll also keep an eye on how the PSI's rise as they warm up.
Good question, but I suspect the answer is complex. I suppose in theory it could because the amount force not "dampened" by the tire effects the suspension. It gets complex from there though (at least for me) because the suspension consists of a spring that actually absorbs much of the force at a rate (speed) controlled by the damper (shock absober) in both the action (compression) and the correspnding reaction (rebound). Even this is an oversimplication because other suspension components and even the "suspended vehicle" ultimately get some of the force. After all is said and done, the answer beats the heck out of me. Bring in the physicist.Question: does a higher inflation pressure affect damper ("shock absorber") life?
Oh, now I seem to remember. Isn't there some need to make sure your TPS street wheels are not within a certain distance of the track so your onboard computer won't pick them up?No TPS on my track wheels. Since I check them after every run, there's no need. When on the track, you KNOW when a tire goes down...
