Ill start with my current set up first rears are 19inch Goodyear Eagle F1 run flats and the front i have 18inch goodyear eagle f1 at first i loved the tires and buying the set for 400.00 total from my buddy who had them on his 06 corvette is not a bad deal either. since the weather is getting cooler here in Phoenix AZ ive noticed my fronts lose 10 PSI after ive driven all day and find myself putting air in the front tires every day i took them over to goodyear and there are no leaks and are in good shape. and having the run flats in the rear i find it hard to get good traction on take offs. ive been thinking of getting new tires a few people have suggested Nitto SSR but im open to suggestions at this point

I would give these a look if traction is an issue and you have a wide enough rim to fit. 19's aren't the best size for traction on these cars.

Don't have tire suggestions but if you've had your tires looked at and you are still loosing air not associated with pressure drop due to temperature or altitude changes, then you might look at your valve stems...especially the needle inside to make sure it's not gotten loose and leaking air. However, if you have good valve caps then the needle probably isn't the issue. Also I've had cracked rims leak air before...so that's something to look into. It's sometimes hard to find. That's the only suggestion or ideas I can come up with. Good luck.

soapy water in a squirt bottle might help. spray around the beads and valve stem. if its leaking, it will show.
