LT tire pressure question

[TXGREEK]

Tire shopping today gives you so much more variety and tread patterns that were never available 10 yrs ago. Run them at the tire pressure that makes you comfortable having them at. You’ll find critics on every page, do what’s right for you. Good luck!

i run 30 psi up front , really softens the ride, after 20 minutes driving the road/brake heat increases the pressure another 5-7psi

At 30psi, I’d keep an eye on them.

30 PSI is too low.

I do 35 on all my P tires for every truck I've had and it works well.

This should not even be a question.  The tire needs to be inflated to the pressure required to carry a specific load.  If the wear pattern suffers because of it, then perhaps you shouldn't be running an LT tire in an application it was not designed for.  Not a single 1/2 ton pickup needs an LT tire for durability or load.  Running over a nail, screw and hitting a curb are not the fault of the p metric tire.  The same items would most likely damage an LT tire.

That should not even be a comment. It's a question because P tires weren't supplied on this man's truck. Therefore a recommended pressure isn't given on the door for the tire type. I've been many places where a P tire would not last. An LT tire is for peace of mind . The trade off is a bit rougher ride. 

 

To say not a single 1/2 ton pickup doesn't need an LT tire is extremely ignorant. They're much more resistant to flats. Try being hours from a city center in the middle of -30*C and sharing roads with heavy equipment. Ruts, ice, debris, anything can cause a puncture. I've experienced first hand guys with P tires topping them up every few days while guys with LT tires never worried about it.  That's just one example.

 

How far down the hole would you like to go? How many pickup truck owners just buy groceries with rig? Maybe everyone should just drive midsize sedans since they aren't utilizing 100% of their truck.

Obviously you don’t live on a gravel road...

 

This is about as stupid as GM selling us Goodyear SR-As as “all terrain”...

False info bro. You can barely drive over a curb with p rated tires. Lt tires take abuse and keep rolling. Only thing good about p rated tires is mps and cushy ride, but you'll get stuck on

wet grass if you don't have 4wd.

The SR-A is awful. The Eagle LS-2 is not horrible as a highway tire, until you grow up and get Michelin tires. [emoji106]

You’re not serious are you?? LT Tires should be inflated to “tire manufacturers” load psi chart and not what the sticker says on the door from the auto manufacturer. Each tire manufacturer has their own load psi chart.
When compared to p rated tires, LT tires absolutely destroy p rated tires on all torture tests hence the reason why they’re the only tire used for off-road driving or heavy hauling. LT tires, they’ve definitely come a long way from back in the day.

There are a great many people on these forums that don’t keep their trucks stock, I being one of them, instead prefer to enhance their off-road capabilities being higher ground clearance with much better traction in mud, snow, sand etc.

1500s have indeed com from the factory with LT tires, usually in Load Range C.

 

With an old work truck, I had to replace seven tires in one year.  The boss kept putting P-Metrics back on it.  Finally, I had enough of time wasted and money lost sitting in a tire shop and found an LT flotation tire that actually cost less and that was THE END of broken tires for the next two years, not even a flat or nail after that.  As a plus, she stopped getting stuck too while visiting my remote customers.

You guys crack me up. So many tire engineers on here, I had no idea! hahah

It's ok to be in denial... Sometimez its hard to admit your wrong. Do yourself a favor. Have someone drive your p rated tires over a curb and look at the side wall fold/collapse and you'll see your wrong.

Doesn’t take any sort of engineering know how to know your absolutely incorrect. It just says a lot when you’ve got nothing but excellent tire wear and reliability coming from over 30 years of running LT tires stretching from SUV’s to trucks. In most instances and totally understandable, LT tires are much more expensive and the average individual can’t afford to spend more on a set of tires just to get them from a point A to point B and instead make up reasons as to justify having less of a tire, just makes them feel better. I’ve never told anyone to get rid of their p rated tires, just expressed my views. Good luck and be safe.

It amazes me how some people don't understand a simple concept, are never wrong.

Just look at the difference in the construction of the 2 tires not to mention the weight difference of the same size tire.

The old saying " There's a sucker born every minute"

My saying " There's an idiot born every 61 seconds"

P rated tire = city trucks, garage queens, grocery hauler or pavement queen.

LT tire = towing, hauling, off road, dirt roads.

 

I put nothing but LT tires on my truck. Always have.

Changing a tire on the side of the road is dangerous.

Cops, Sheriffs, tow truck drivers get hit working on the side of the road, it's a problem.

With some people, won’t make a difference going through trying to explain, no matter an enormous amount of experience anyone has, some people are just different, and that’s ok, as long as they’re happy with their decisions.
