The max tire pressure rating isn't the same for all 145R12 trailer tires so you'll need to look on the actual tire sidewall for the load range which should also state the max tire pressure rating. We recommend filling the trailer tires to the max tire pressure rating listed on the sidewall while cold. The Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire part # AM10140 for example has a load range e rating with 80 max psi.
