Is 125 PSI Inside a Load Range G 235/80-16 Trailer Tire Too Much While Warm

Updated 07/25/2019 | Published 07/24/2019

Question:

When I fill my tires cold to the recommended 110 lbs g rated in the SW desert, the traveling pressures often top 125 lbs. Should I be concerned with this?

The recommended cold psi rating for your Westlake 235/80-16 Tires will take into consideration the increase in both temperature and pressure as they warm while in travel so no, you should not be concerned. I don't really have a max psi while warm but if the temperature inside the tire reaches more than around 160 degrees then you could be at risk of a blowout. If you want to be more cautious of your tires then your best option is to install the TST TPMS for RVs part # TST-507-RV-4-C which will monitor both pressure and temperature so that you can be alerted to any potential blowouts.
