What PSI Should Trailer Wheel and Tire be Inflated to In Size 5.30-12  

Question:

Hello I was reading some of your replies to other customers regarding the proper PSI for a C rated tire, size 5.30-12. I have an old pop-up camper chassis that Im using as a trailer for hauling all sorts of things, dump runs building Material pickups, etc. The post I read last it was recommended that you always go to the max range ad PSI and fill them up while theyre cold. The question I have about that is on my current set of tires, it states 80 psi cold in one place, but on another part it says inflation above 32 psi could cause fatal blow out. So Im a little weary to start pumping more into these things without hearing first from an expert. Im also looking for a recommendation on a decent set of replacement tires with this size, two of them and I need them on rims with four lugs. Thank you in advance I appreciate the time.

Sounds like maybe you have more than one brand of tire on your trailer and there is multiple PSI requirements based on that. It is correct that you should always run the max pressure in the tire listed on the sidewall otherwise capacity is diminished and likelihood for failure is increased. For a wheel and tire in your size of 5.30-12 and a wheel bolt pattern of 4 on 4 like you need the part # AM30790 would be a really great option.
