Re: Trailer tire pressure.

But on cars, & trucks, I intend to keep doing as I always have been for 45yrs,

Oh, 'my bad, I thought the thread was titled Trailer tire pressure. And I'll keep running my passenger vehicles at a constant 35 psi year round. Sorry, I'm not anal enough to adjust pressure based on how many passengers I have. You'll be pleased to know, however, that I may change, seems as I may only get about 85,000 out of this set. Agreement is not required or expected ... ;)

Re: Trailer tire pressure.

Something else to consider with those smaller trailer tires is that lower pressures don't afford the same rim protection. There's less rubber between the rim and road on a small tire. Things like pinched sidewalls and heat build up all come into play. Besides, most boat trailers don't do much running empty, the only weight differences most see is between the amount of fuel gear on board the boat itself.
If the tires are riding too harsh, then maybe a lighter tire may be in order?

I have one trailer that did double duty, it hauls both my trihull and my aluminum Starcraft. With the 5.30x12 6 ply tires, it rides well with the trihull, but with the aluminum boat, its like it's riding on rims. The trailer was fine with the lighter boat until I upgraded the tires to accommodate the heavier trihull. I finally ended up getting another trailer for the lighter boat now with lighter duty tires to solve my problem.

Neither am I, as I said, I find the right pressure for the maximum load of the car, or truck, and maintain it there.

Jeez, only 85,000? My last vehicle bought new, a 2002 Santa Fe LX 4WD V6 had BFGoodrich long trail T/A's and was traded in for a new 2005 Tucson LX after 3 1/2yrs and 87k miles, and there was still maybe 10k or more tread life left on the tires! and I didn't really bother to check the tire pressure much, or get regular rotation, or unnecessary alignment, and despite that they still wore well, & evenly! But, that was average for that particular vehicle, with those tires, according to the Santa Fe forum, in fact some members got 100k out of these.

Here's a bit of inflation info from a reputable source:

not to get too far away from the original thread here...but having read the above statement, i gotta say a BIG AMEN! BROTHER! i dont rotate my tires or get front-end alignments, and have yet to have wear problems. to me its kinda along the lines of replacing the races with the bearings...ya know... your tires are gonna have their own particular wear pattern based on their location. You start rotating and re-aligning, its kinda like upsetting the delicate balance of nature :D

as far as my trailer tires go... ive got em filled up to the max that the sidewall of the tire says, it happens to match what the sticker on the trailer says. but if i was a few pounds off, wouldnt bother me too much since i generally go about 4 miles round trip.

Re: Trailer tire pressure.

I replaced the tires on my boat trailer this year, not because the tread was low or because they were worn out, but because they were old. Heck, according to the amount of tread that there was left they were probably good for another twenty years. I always inflate the tires on all of my vehicles or trailers near or to maximum, but one thing that I know for sure is that they run cooler. On my former 92 Dodge 4x4 with the Cummins Diesel I had over 100,000 km on a set of Michelin XPS Traction tires and was running them between 75-80 lbs pressure, before I replaced them and they showed no uneven wear. Mind you I do rotate the tires on a regular basis on my vehicles.
