Tires state "Max Load xxxx at Max yyy PSI inflation". Go take a look! They do NOT say inflate to 80 lbs (LRE). Call your tire manufacturers CS number and see what they say. Chris

So you would rather max the tire out by under inflating it rather than having the capacity it was built for? Every tire I have ever bought has come out of the shop/dealer fully inflated. If the tire wasn't intended to be run at a given psi, it wouldn't be stamped on the tire. I obviously don't understand the logic of not using all the capability you have.

I highly recommend you contact the tire manufacturer of your choice and talk to their tech support so you can understand PROPER inflation for the load placed on the tires.

OP try carrying some water ,i carry approx 30 plus gal and find it will really dampen the suspension.

That's maturity. Can't Have it your way so not playing in the sandbox. Hard to argue with facts. Good night gentleman. Happy travels to you.

Glad to see we finally agree. Quoting from your link:

TIRE SAFETY
Everything Rides On It

Studies of tire safety show that maintaining proper tire pressure, observing tire and vehicle load limits (not carrying more weight in your vehicle than your tires or vehicle can safely handle), avoiding road hazards, and inspecting tires for cuts, slashes, and other irregularities are the most important things you can do to avoid tire failure, such as tread separation or blowout and flat tires. These actions, along with other care and maintenance activities, can also:

Improve vehicle handling
Help protect you and others from avoidable breakdowns and accidents
Improve fuel economy
Increase the life of your tires.
This booklet presents a comprehensive overview of tire safety, including information on the following topics:

Basic tire maintenance
Uniform Tire Quality Grading System
Fundamental characteristics of tires
Tire safety tips.
Use this information to make tire safety a regular part of your vehicle maintenance routine. Recognize that the time you spend is minimal compared with the inconvenience and safety consequences of a flat tire or other tire failure.



Safety First–Basic Tire Maintenance

Properly maintained tires improve the steering, stopping, traction, and load-carrying capability of your vehicle. Underinflated tires and overloaded vehicles are a major cause of tire failure. Therefore, as mentioned above, to avoid flat tires and other types of tire failure, you should maintain proper tire pressure, observe tire and vehicle load limits, avoid road hazards, and regularly inspect your tires.



Finding Your Vehicle's Recommended Tire Pressure and Load Limits

Tire information placards and vehicle certification labels contain information on tires and load limits. These labels indicate the vehicle manufacturer's information including:

Recommended tire size
Recommended tire inflation pressure
Vehicle capacity weight (VCW–the maximum occupant and cargo weight a vehicle is designed to carry)
Front and rear gross axle weight ratings (GAWR– the maximum weight the axle systems are designed to carry).
Both placards and certification labels are permanently attached to the vehicle door edge, door post, glove-box door, or inside of the trunk lid. You can also find the recommended tire pressure and load limit for your vehicle in the vehicle owner's manual.



Haven't countrd how many times "proper tire pressure" is stated. But it's enough to make the point that

Not sure how many times "proper tire pressure" is mentioned, but those accompanied by the statement " Underinflated tires and overloaded vehicles are a major cause of tire failure. Therefore, as mentioned above, to avoid flat tires and other types of tire failure, you should maintain proper tire pressure..." pretty much illustrates my point.

So you would rather max the tire out by under inflating it rather than having the capacity it was built for? Every tire I have ever bought has come out of the shop/dealer fully inflated. If the tire wasn't intended to be run at a given psi, it wouldn't be stamped on the tire. I obviously don't understand the logic of not using all the capability you have.

Ok, so reference the picture above.

So assume I am running empty with about 3,400# on my rear axle. That is 50% of my my total rear tire capacity.

If running 40 to 45 psi the tire will look like the the tire on the left, CORRECTLY inflated for the load they are carrying.

If inflated to 80 psi with the same 3,400# load it will look like the tire on the far right.

Conversely, if the tire is inflated to 40 psi, and the load on the axles is 7,000# (MAX load) the tire will now look like the tire in center.

If the tires are now inflated to 80 psi, it will once again look like the tire on the left.


The result of correct inflation pressure for the current load, is MORE TRACTION, and longer tire life.

Remember that label on the side of the tire states MAX pressure for the MAX load!

Please look up the dictionary definition of MAXIMUM.
As in MAXIMUM load of xxxx# at a MAXIMUM pressure of xxx psi.
If all tires were meant to run at that max sidewall pressure, why would manufacturers provide load/inflation tables that provide required pressures for loads less than the MAXIMUM rating?
Why would GM put a sticker on my truck that states 60psi front and 80psi rear FOR THE SAME SIZE TIRE!
Most passenger car tires have a max psi of 44. I guarantee that most cars run between 32 and 35psi.
Why is that?

Mine don't, and haven't for hundreds of thousands of safe miles.

OK, you do your thing, the rest of us will do it RIGHT!

Out!

Again...proving my point. THE STICKER SAYS 80. The great part of this is that we can all run however we please. You run low, I'll run as intended.

Maybe we are being punked?

Or someone does not own a phone to call Michelin, Goodyear or Firestone to get educationed? Snoking
