Tire Pressure On a Wheel House

Recommended Posts

This seems like a simple question but still confuses me. My radial tires say 2540 lbs max load at 65 lbs pressure. My house weighs 4450 lbs. Should I run them at max pressure of 65 lbs? There's no door sticker to tell you like on a truck or car.

Hoo boy...that's not real good, Hawg.....but ya, max pressure on those, if you're going to run them....but, you're over the safe limit or close (figuring in gear) ...Not trying to be a smartie, either. 

 

 

The tire’s load rating, or “max load,” indicates the individual tire’s safe maximum load-carrying capacity when inflated to its recommended pressure. Never exceed a tire’s maximum load rating (the limit that is molded into the tire sidewall) or the maximum vehicle load limit shown on the vehicle tire placard, whichever is less. The tire is designed and constructed to handle a specific maximum load, and overloading will result in a buildup of excessive heat in the tire, which could lead to tire failure.

The load index number, which appears on the tire sidewall, is an assigned number that corresponds to the tire’s load-carrying capacity. Alphanumeric tires will display an alpha code that indicatesmaximum load. The letter can range from “A” to “N” (the higher the letter, the greater the load-carrying capacity at a given inflation pressure).

The max load and maximum inflation numbers found on the tire sidewall indicate the maximum load that can safely be carried and the maximum allowable tire pressure. The construction of the tire (belts, bead, carcass, liner) dictates the tire’s ability to withstand pressure. The stronger the reinforcements, the greater pressure the tire can h

I'd stop at least a few times to let heat dissipate. Max psi of that 65 lbs, because it's the tire sidewall flex that will get ya into trouble and build up the heat.

Figgered ya did. Just hate to see anyone lose their house due to a blowout. Watched it happen before. I'm just really "over-cautious" on stuff....

I think most of the time trailer tires are recommended to be operated at max air pressure. It should also help the tire wear more evenly and help prevent a blow-out.

Rebs, it’s actually 2640 but I know you know your stuff on this. I should run at 65#s right. I’m actually 20 some % under max

Yup, Hawg, 65# on a cold tire. (measure them now, before it's like 10* out.....best temp is around 50-70* for a "true" temp, as air pressure will actually drop a tad when it's below the freezing point. Some high-end car guys in my club (worse than me) actually do the nitrogen tire fill, which IMO, hasn't been significantly proven yet. I just make sure my air tank/compressor  is drained after EVERY use, and my filter is working to keep out moisture. I also do a tiny squirt of WD-40 on my Schrader valve once a year in winter. ((keylock holes in doors too)  Do NOT fill tires at an outside air hose place in winter!!!!!!!!!!! (Or anytime, really)  OK, enough of tires 101 for today. I need a Pepsi.  :grin:

I'm a Pepsi guy! And I'll flip ya for the buy! No slow learner that I see...not you, anyway. :P Just glad I can help! (I hope I did....I think we all gave it a whirl)

    • Pumper don't forget to register your bird.
    • Had 3 long beards come out gobbl8ng and running but not to me.  Had them all fired up but they obviously had another destination in mind.
    • I didn’t know grackles fished either.  Interesting. 
    • Was checking back to see you with a bird pic @Borch
    • So this is not a new thing!  Interesting.  I keep finding more and more complex behavior in so many of these "dumb" animals!  So many of them are anything but dumb.
    • When I was a kid, we used to have a pond in our yard. We would keep fish and minnows in there. The grackles would clean in out! We had to resort to putting a cover over it.
    • Last Thursday on a visit to my sister in Rock Rapids IA, we made a circuit through the Island Park there.  At the low dam just past the former railroad bridge which is now a walking path we saw a group of grackles fishing at the edge of the white water where it ran against the rocks at the shore line.  There probably were a dozen or so all told moving back and forth and some on the rocks at the other shore line.  In something like half an hour or less we saw various of the birds bring out minnows and eat them on the shore to a total of at least 8.  They also contested for the better fishing spots and tried to horn in on other birds' catches;   they would fly out to quite a bit up on shore with a catch to eat it there. I never expected to see grackles fishing.  I never heard of that before, but then it wouldn't be the first time I didn't know about something relatively common.
    • I've seen deer there, too.  I go by there on my way to work about 3:30 am S S & M.
    • Now they're gobbling...  seem to be getting a little closer.
