I recently purchased new nitto terra grapplers (285/60/18) and the rear left tire slowly is leaking. Now ive noticed this since i bought them, but it seems after each time i "re-fill" the tire with air, it leaks out faster, like over a couple weeks or so. Whats interesting, is i had the same problem in the same wheel on my previous set of tires. If the wheel is cracked or the chrome is peeling, is there any way to fix that, besides buying a whole new wheel itself? Has this happend to anyone else? Opinions, tips, and any suggestions would be great! Thanks in advance
