I purchased a 2009 Cardinal had them change tires as 8 yrs old. ST 235-80-16 were stock tires recommend 80psi for max load for rim of 3100 lbs. they changed tire and put on ST 235-85-16 max on sidewall of 95 psi and for load 3800 lbs. I went to,tire dealer to see if I could run them at 95 psi on the rims. They said run them at 80 psi and that would be fine good for 3200 lbs per tire. I had them put in steal valve stems and balance tires. Question is,would I,be ok with 80 psi. That is more tan enough for the weight so I,believe it would be ok?
OK?? Probably, but experts say run STs at max pressure, for cooler running, less flex, scrub, etc. If wheels are only rated to 80 psi, I would not air to 95 psi. IMO, it makes no sense to over tire, then lower pressure, to work with lower rated wheels, when the OEM E rated tires are adequate, and lasted 8 years, with no issue.
I know tire dealers like to sell what they have on hand, but I would have requested ordering the proper tire, or looked elsewhere.
