Tire Air Pressure

[Greg986]

What tire air pressure are you folks using? The recomended numbers from Porsche or something else? Lower pressures

for spirited street driving? Different pressures for maximum mileage? Any help would be appreciated.

I know that for my motorcycles using pressures different from those recoended by SuZuki result in better tire

mileage and handling. Take care, Greg

I apologize if this subject has been frequently discussed before. I searched this forum and could not find any

such messages.

The Porsche recommended air pressure gives a fair amount of understeer, which Porsche's lawyers probably figure is good from a liability standpoint. I run 30-31 PSI in front and 36 PSI in the rear and it seems to work fine for me. At least, that's what my tire pressure gauge says and I've never calibrated it

I don't get excessive tire wear, but also keep my tires properly inflated and balanced, and get an alignment every two years or so.

I run 30-31 front and 35 (maybe 34 next fill) rear and watch tire wear closely. Turn in is improved and it is not tail happy at all. Rears worn out at 20k miles, but evenly worn. Fronts still good but have reached old age. And I've never had an alignment.

Yep, I also run 31 front / 35 or 36 in the rears. I have not had an alignment since owning the car (it's an 01), and still have even wear on my tires. LOL. Steering wheel points perfectly straight as well as the steering itself, so never bothered to get it tinkered with.

I have an 03 S and I run 38 front 40 rear. I like the feel a lot better. Not as soft in corners.
