Trailer tire pressure

[kozachok007]

I recently purchase a boat/trailer and noticed that the tires on the trailer are at 15 PSI even though MAX tire pressure marking is listed as 60PSI. Should I bring them up to 50PSI and leave some room for expansion due to heat?

Re: Trailer tire pressure

Take it to a tire dealership and ask them to check for the correct tire pressure. You don't want to guess the pressure if you are not sure. Call them and tell them the make of the tire and what is the recommended tire pressure, they will tell you. Good Luck.

Put more air in them before you take it anywhere though, 15 PSI is way low. You'll wear tires in a bad way and possibly wreck a wheel if you hit a bump going fast. If you're worried about too much pressure, you don't have to go all of the way up but make sure that they match. I keep mine around 55 PSI and most others that I know of call for about the same. Make sure that your gauge is good, if in doubt just get a new one.... you'll use it later, I guarantee.

most trailer tires are in the range of 50 to 80 lbs. inflate them to whats on the tire. low air pressure is the # 1 reason for trailer tire failure. low pressure causes them to run hot, besure they are ST rated trailer tire. car tires don't belong on a trailer.

60 PSI is the cold tire pressure. The expansion due to heat is already taken into account.

What a great thread! I just checked mine this weekend and they were at 22lbs. Tire rated at 50lb COLD. So I aired them up to around 46lbs (maybe I should go ahead and go up to 50?). Anyway the trailer towed WAY better and the tires weren't nearly as hot. I couldn't believe I hadn't checked the tires since I bought the boat earlier this season.

Just glad I didn't have a blow out!

pump 'em up to 60..........and make sure your spare is in good condition - if they've run a long time at 15, they could blow at any second..................

Re: Trailer tire pressure

Tire pressure should be checked before every trip. It wouldn't hurt to do it on the tow vehicle as well. I believe the number is 80% of the vehicles on the road have at least one underinflated tire.
