Tire pressure KDW2

That's a lot of pressure.
Stock tire pressure is 30psi with a 245
With a 295, you could run a lower pressure since the footprint is larger but the cars weight has not changed. You'd have to experiment, but 27-30psi would be the range

no KDWII's are diff, they have a max at 51psi ( to seat it at install) but average psi is like 39-42. I have my KDWII's fronts at 40 and my backs at 38-39

yeah mine took about 65 but they are all 275's, theres another thread in tech here about traction and he runs his w/ like 28, thats pretty low. Im pretty sure 36-39 is where you want to be for performancemerc123 said:

A really good way to check is buy one of those laser temp guns....an accurate one. Go drive your car for a while, get out and shoot the tires across the tread and check for equal temp.
If the center is hotter than the outsides, your pressure is high and you need to drop pressure. If the outsides are higher, then you need to add air.
If you are wearing more in the center now, that's a pretty good sign you need to decrease pressure as the tire is bulging out

Correct me if I'm wrong, but doesn't plus sizing your tires require you, or suggest that you, add a couple of PSIs? From my understanding, it has to do with the load index of the different sizes of tires. They talk about it briefly on Tire Rack and Discount Tire Direct in the info section.
That laser temp gun idea is cool. I think I need a new toy...I mean tool.

that is due to over inflation.
i work at a tire shop, and i'm sure you should NEVER run 40 psi in your tires!! the pressure on the sidewall is the MAX a tire can hold. it doesnt matter how much it takes to seat a tire. hell, i've put 120 psi in one to seat it, that doesnt mean you need 50 psi to run it.
just run 32 psi and you will be fine. anythiung over taht is just stupid. 40-50 psi is for 2500 series trucks! the size doesnt matter you can run a 215 or a 295 and they will still be the same PSI.

no they are not!!
you can run any brand or type of tire on the same car at the same PSI. as you said that is the MAX pressure. and you can excede that limit to seat them. trust me i have been doing low pro's for the past 4 years.
i run 32 all around
easiest way to check if your over inflated is to leave two nice 20ft long tire tracks (up to you to decide how) and check the width of the markings you left behind
