How does everyone else maintain 35 psi in their tires? I have inflated my tires over a bit at the gas station in the evening and in the morning I check and drop the psi, as required.

Let's say for example . . . your tire pressure is a cold 30 psi in the morning. I then drive down to the local gas station and the psi has risen to a warm 35 psi. Is it safe to assume that I can inflate that said tire to 40 psi?

Or does the psi actually rise that much from driving. Saw the other thread about psi and that generated this question. I didn't want to jump in and ask about this on someone elses topic.

I notice that my pressure rises about 2 psi from cold pressure (no hard driving). If I'm low (which has only happened twice in a year), I over fill slightly and leave myself the opportunity to purge some pressure after the tires cool down. Being a couple of psi high isn't going to be a problem for a couple of hours.

Thank you.

get an air compressor, only takes a few minutes to get my tires to 35 psi. I do this in the morning, every Sat before I go out while the tires are cold, and use a digital tire pressure guage

make sure your car's not in the sun too long in the morning before you check your
tire pressure cause that side of the car will show higher pressure than the shaded
side.

check your tire pressure in the morning in your garage every 1-2 weeks.

Now there's a thought. The reason for my concern is that, I have never riden on rims and tires of this size (19" OEM). And as such, it seems that + or - a lb. or two will make a big differnce.

Thanks for eveyones' comments and thoughts, as usual.

Unless you drive very hard and fast, your tires won't rise more than a couple PSI on your trip to the filling station.
Set them at 38 psi there and then lower them to 35-36 in the morning b4 driving.
Best to have a small foot/hand pump and a good digital gauge to be able to maintain your tires anywhere.

Thank you for another great suggestion.
