I personally do 35 psi. More or less tends to make the tires not contact the road correctly. Just make sure when you check it, the tires are cold/ haven't been driven for a couple of hours.
is it in a spot where a plug will work? ie. in the tread rather than the sidewall?Found my slow leak. There is a nail in the tire . I have no money for tire.
you can still plug it for less than 10.00 dollarsThe tires have 77k miles on them. Also have sidewall cracks and only about 3/32 tread. Not worth patching.
