17" S Lite All Season run flats PRESSURE
I noticed that when cornering (not that hard!!) that my tires squealed. I immediately suspected low pressure.
I checked them this morning after a 40 mile highway speeds ride (warm) and they were all sitting at 28 to 29 PSI... Seemed LOW to me when the sidewall pressure recommends a MAX of 51 PSI and they were "warm."
I've just let them sit in 50 degree weather for about 45 minutes and now I'm going to increse the pressure to ~38 PSI. I'll check the door panel to be sure... My question is at what pressure do you run your All Season run flats?
I'll be switching to steel wheel/Blizzaks in a month or so BTW...
TIA,
Dave

I increased my pressure to 38 PSI with the gas station built on gauge (you know those big brass pressure valves that pop out to the indicated pressure) and then I checked it later with my handy-dandy DIAL gauge (0 - 100 PSI) and it read 35 PSI! What to believe?? So I ran to "Autozone" and got myself a 0 - 60 PSI gauge ($7.95) and checked it and it, too, read 35 PSI. I'll be topping off to 38 PSI when I leave again. I'm tending to believe the two personal gauges over the gas station brass thingy.
Well I've got a 66.3 % chance that I'm right anyway, lol...
Thanks for your replies.

I try to keep mine right at 38, but it's a constant struggle; they're always losing pressure, *way* faster than standard tires do, in my experience. Within a week, I bet I lose 5 psi per tire...
I think you wasted eight bucks on that pencil-style gauge. I've read that they're crap. Supposedly the best kind are the dial-type gauges. I've got a digital one, but I'm not sure I trust it, either...
