Trailer tire pressure


aqh

Recommended Posts

Hi, agh...

This question came up some time ago. A Forum member was frustrated that he received only about 3-4,000 miles out of his trailer tires. Obviously, he had under inflated tires which will cause premature wear.

All said and done, I keep mine at 60-62 p.s.i. and their highest pressure rating is 65 p.s.i. No problems. Mine have about 8400 miles on them with no sign of wear.

I have always run my trailer tires at the max pressure listed on the side of the tire.

There are factors other than underinflation that may cause trailer tires to wear abnormally fast. One of those is allignment of the trailer axles. Don't assume that they cannot get out of allignment or even that they came from the manufacturer properly alligned. I have one trailer that continually chewed up the left front tire and inflation had nothing to do with it. The damned front axle was bent on the left side and was that way from when new.

Not all trailer tires are created equal. Goodyear Marathons seem be be made both good and bad. Some seem to last forewver while others have a habit of coming apart.

Final suggestion. CARRY 2 SPARES! An extra wheel and tire, the tire can be used, is not that costly and will give great peace of mind. There is a very uncomfortable feeling when you have lost a trailer tire and used the spare and you are still in the boonies. And, trailer tires [real trailer tires] cannot be had generally except from tire dealers and some of the small ones have to

bring them in.

Finally, remember that car tires are NOT suitable for trailers. The sidewall design of a car radial is too soft and flexible for trailering. And don't consider your trailer as a place to get the last few hundred miles out of your old car tires. Think of the value of what is in your trailer, and then consider getting proper tires.

Sorry to have gotten preachy, but trailering safety is something I have championed for the past 21 years.

Hi, Howard...

(Thank you for chiming in on this subject. Thought it may ring your doorbell.)

agh...

True info from Howard. He has been a proponent for attention to "Trailer" questions for years. Not just tires. He has brought up practically every iota of trailers to include "not the trailer", rather, the tow vehicle's "hitch receiver", of which, most people take for granted.

Bearing grease, tire pressure, load levelers, anti-sway bars, tow vehicle capacities, trailer capacities vs. load, tongue weight (very important subject) all come into play here.

An observation I have made, most recently within the parking lot at the AGNM in Buffalo..."ball hitch grease". Went out to my truck in the evening, walked by roughly 8-10 pick-up trucks. NONE HAD GREASE ON THE BALL! This is a definte no-no. That hitch is moving canstantly as you tow. Without grease, obviously, it is a "metal-to-metal" zone. (I take a hand held grease gun prior to hitching up, grease the ball, grease the receiver end of the sway bars, DO NOT GREASE THE TRAILER END OF THE SWAY BAR AS IT MAY CAUSE IT TO EXIT PREMATURELY".

On this Forum, in my opinion, is a lack of taking advantage of its engine. Go to the top of this page, click on "SEARCH". Suggested search words: Trailers, Enclosed Trailers, etc." You will find a miriad of veteran, and, not-so-veteran experiences with trailering.

Howard and Peter offer excellent advice and I can't really think of anything to add. I run the maximum tire pressure that is noted on the sidewall. Just got back from 42 hours of total towing since the grand national in Buffalo, Ohio, etc, with no problems. Trailering can be dangerous and deadly if not respected and short cuts are taken. Search the achieves as there is a wealth of good information there.

Good point Ron. ....and let us not forget the mishap that the folks from Florida went through on their way to the AGMN with their car. They are very lucky people.

......Being a race fan, after every race NASCAR gives out the "Goody's Headache Award" that goes to the driver who has had the worst luck during the race. Maybe the club could get one of the pharmecutical companies to sponsor something like this for the national meets. I know just off the top of my head in June you had someone who had their car shot at on their way to Hagerstown, in July you had the accident in West Virginia that damaged the car and totalled the trailer on their way to Buffalo.

....It sounds like there are two candidates that have earned an award and/or a few bucks for their troubles and that is one award that I have no interest in trying to get.

A relative tip came to mind a few days ago. A good friend had a punctured trailer tire on the way to a recent Meet. He recounted about having to jack the trailer up via a good Samaritan...you do not need a jack on a dual-axle.

I carry a 15" long piece of 4x4 that is cut (beveled) on one end specifically for the possiblity of a flat.

i.e...if your right rear tire goes flat on the trailer, simply put the 4x4 in front of the right front tire, pull the trailer until the right front is dead-center..."instant jack". (or, look for a suitable, angled rock along the berm of the road.) Provided that your trailer tires are inflated to the max, the good tire will lift the deflated tire enough to change it.

P.S...make up 4 beveled 4x4's and you can use them for wheel chocks if you must unhook your "loaded" trailer in a designated trailer parking lot at a meet, hotel, etc.

All,

Thanks for all the tips. I will cut some scrap 4x4 shortly.

I just returned from the NAOC meet. I saw the bullet hole in

my friend's trailer and his '23 Olds. He was headed to the

Hagerstown meet.

Later,
