Where to Find a Tire's Required PSI Pressure Rating

Question:

I have a tent trailer and got the following tires. But I cant seem to locate the cold psi rating. Attached is a pic if the side wall, I know that 102 isnt correct. Any insight you have would be great.

Your trailer tire will have a lot of information noted on its outer sidewall. This will be molded into the rubber. Some of this information will be fairly small and may require wiping down the tire to remove any dirt in order to see it. The type of information noted on a trailer tire includes the tire size, for example 5.30-12 as with yours; its weight Load Rating; correct cold PSI tire pressure and sometimes a speed rating letter code. The tire's correct pressure will be noted somewhere on the sidewall.

Trailer tires should ALWAYS be fully-inflated to their maximum rated cold tire pressure. A tire cannot deliver its rated capacity unless properly inflated.

Most likely your tires have a PSI rating of 80- to 105-psi, depending on its weight load range, but checking the tire sidewall will confirm. All tires in your size are shown on the linked page.
