two questions?
i just change my run flats to non run flat, are the tire pressure remaining the same 36psi front/39psi rear

tires size are 225/40/r18 255/35/r18 rear

im interested in filling my tires with nitrogen. anybody ever got it done? is it worth the money, also i read it improves the ride quality

i did not feel any diffidence and i kept my pressure front 37 rear 40

there is a wheels and tires forum for that type of question. The nitrogen issue is more suited to maintaining PSI and resolving the gas expansion factor when the tires warm up.

Most people keep the same PSI, though dropping 1-2 will improve ride and handling at the cost of increased wear. Nitrogen is nice if you go to the track or live in an area with wide temperature variations and don't want to check your pressure occasionally. Otherwise, not worth the cost.

Nope. That's another way for them to take money out of your wallet.

Especially since your tires are already filled with 78% nitrogen.

Nitrogen... what a freaking scam.
