Trying to go to Murray tomorrow, I hooked up the boat and looked at the tires(brand new). They look low so I need to go to station for air. I looked for psi and it says 80psi, would that be right? Just wanted to know before I did anything. Thanks

what type tire and size that would help !!!!
Ok sorry, it's a 5 30-12 Power King.
that is the correct psi for that tire I would put them at 75 psi cold and when you run them down the road they will build up the pressure as they warm up !!!Quote:

That PSI on the tire is for the maximum weight the tire if capable of carrying. The lighter the boat the less pressure you would need for a compromise between correct pressure and best ride and wear. Same thing goes for the tires on your car, the recommended PSI for each individual car is on a plate usually inside the door frame. This PSI is usually a good bit under the maximum rating on the tire because the tire is made to fit many different size and weight cars.
Problem on a boat is you don't have that info on the trailer since you can out a variety of boats on it. I have the same size tires on my Tracker and I fun about 55PSI in them. I estimated the weight of the boat, motor etc. and had my tire dealer look up the recommended PSI for it.
You won't do any short term damage if you run 80PSI, but if you made a lot of long trips you could get some uneven and premature wear if 80 is way to much for your needs. but if you got a heavy fiberglass boat with a big outboard, then you may need maximum pressure in the tires.

Trailer tire safety tips
- Maintain pressure at the maximum PSI recommended on the tire’s sidewall for cool running, load-carrying ability and lowest rolling resistance.
- Keep a cap on the valve stem to prevent contamination of its internal rubber valve.
- Always carry a spare and check its pressure along with your trailer’s other tires.
- Don’t overload trailer tires. Maximum load is listed on the sidewall. Single axle tires can handle 100 percent of their rated load. Dual axle tires must have their loads reduced by 12 percent below the rated amount.
- Visually inspect your tires before each trip. Check the pressure before you use your trailer. On long trips you should check your tires’ pressure every morning when the tires are cold.
- For long-term storage: cover your tires for UV protection or keep them in a cool, dry place.
- Replace every three to five years, regardless of tread wear.
I run max pressure in all my trailer tires regardless of weight of load. I've never had any problems, but that's just my experience.
hmm....and I thought all boat trailer tires ran at 50 psi. Well, that's all that mine has always said. Guess I just didnt buy the right tire that says 80 psi. Run at the pressure the tire calls for.
I had A trailer I hauled a front end loader on and seemed every time I had to move it blew at least one tire was running 60 lb. in um
got to looking and saw max air 90 lb. cold. I thought 90 lb would blow that tire in a thousand pieces so I wrapped up with 3--4 chains to
keep it from killing me completely dead and pumped er up to 90 == that solved the problem. -- just my :twocents
Way back when, I used to work out with a Quality Engineer from Continental/General Tire in Charlotte. He often told me that tires performed better when pressurized to their max cold pressure. Something about less heat buildup and better sidewall stiffness. More air pressure may also give you less rolling resistance, hence better fuel mileage. He also told me OE grade tires (those that come on new vehicles) were the best tires you could ever get. As an aside, he also told me Michelin had the best quality tires, at least back in the 1990s. Given that, I would go with the trailer manufacturers recommendation on tire pressure as the low side range, and the max sidewall cold pressure as the high range. I have always run mine near the max with no issues. On passenger cars it can make the ride noticeably harder.
I know one Thing, don't go on looks. I blew up a tire putting air in it till it looked right
I saw that happen once = I a kid came by a station I worked at to pump up his bike tire I told him to hold upQuote:
