I check and adjust the tire pressure monthly as needed to factory specifications 31 psi front, 35 psi rear. New tires bought at 42,710 miles, (3rd set, I believe, as car was pre-owned). Car now has about 54,250 miles on it and front tires look like they will be down to tread wear indicators in about 6 months. No leaks from front thrust link bushings. Could be a couple of bent rims or alignment issue? Tread wear appears to be even.
