Tire Pressure

[tski97]

What is everyones opinion on tire pressure. Do you use the number on the tire or what the trailer says. My trailer says 35 and the tire says 50.

Run what the tire recomends.

RE: Tire Pressure

Trailer. Just as on your vehicle the pressure is based on the load. This assumes the trailer's recommendation is based on the boat load. There is a ratio of pressure to load, that is why auto manufacturers will recommend you bump up the pressure if your carring a large loads.

I went by what was on the trailer...50 psi.

RE: Tire Pressure

The tire carries the weight. The trailer tag does not know what tire is on the trailer.
To really answer this, you need to know the weight being put on the tires.
Each tire has a rating of pounds, at a specific air pressure. If the weight of the boat, trailer, gas, gear, and anything else being carried by the trailer tire is a lot less than the weight rating on the tires, you can get away with lowering the tire air pressure.

You will get better gas mileage with the trailer tires inflated to their max pressure.

A fully inflated tire flexes less, and does not build up as much heat internally. Many tire blowouts are caused by the tire being underinflated, and then it flexes more, gets hotter, and actually ends up at a higher pressure than normal, and then the hot weakened rubber gives out.

Absolutely!! You should run NO less than 5 lbs. below max. Side wall break down and separation will occur MUCH faster if under inflated.

I run 60 psi in mine...........single axle.

I run 80 psi in mine, single axle with load range E tires iirc.

Goodyear advises to set tire pressure of their Marathon radials according to what the trailer specifies. Note that the placard on trailers state the recommended tire pressures for the MAX weight the trailer is designed to carry.

From Goodyear information statement on their Marathon trailer radials:

Of course if you have Carlisles or some other brand of trailer tire, it may be best to follow other recommendations on this thread. :grin:

Interesting discussion on the MC forum too... Take note - there's a guy that had really bad luck with the Carlysle tire.

I've had bad luck with all these tires but what I've found perhaps was not bad luck but age. After 5-6 years of little use and stroage outside, the tires get tired and need to be replaced. That being said, I run mine near the max pressure regardless what the trailer says. I also make sure to bump my tow vehicle pressure when the load is added.

Another tidbit for ya.............during winter storage, if your boat stays on your trailer like mine does, and you leave the wheels and tires on instead of jacking the trailer up and taking them off, bump the air pressure up 10 lbs. above the max to help support the side walls.

Max tyre pressure is stated on the wall of the tyre, don't exceed that for safe use. Check the pressure with the rig loaded for transport, that is with wheels on the trailer. And stick with a reputable brand.

thanks all for the replies. I think i will try 50 psi and see how that works.
