how do you go by the recommended PSI? i mean you said you go by what is listed on the sidewall.. if you go by that you'd put in exactly what it says.. but your recommendations are a little less. How do you calculate that? Your recommendations are different (90% and about 88%)Now I wouldn't necessarily recommend 50+, but I always go by the max psi rating on the tire's sidewall. If it says 44, I recommend 40. If it says 51, I recommend 45. If you put 32 psi in a tire that has a max psi rating of 44, you WILL see uneven tread wear.
just curious...
