LT Tire Question ???

Hello All

Need 2 tires on my (new to me ) TV. I want to upgrade to LT tires and plan on putting the new ones on the rear. Is it ok to mix LT with P tires as long as on the same axle ???
Thanks Jim

"P" Passenger, "LT" Light Truck, I really don't see a problem with putting two new ones on the rear. When you mentioned "butting" I thought you may be talking about a dual rear setup but at looking at your truck it is not a dually. The "LT" tire should give you a little higher load rating.

rideandslide,
It is ok to put LT tires on the rear and P on the front. Saying that, you have to be careful of the wheels. You need to check the load rating and maximum pressure that is stamped on the wheel, your tire shop can find these numbers for you. Also you have to upgrade your valve stems from the rubber one to the bolt in steel ones to hold the higher pressures.

I wouldn't do it on a tow vehicle you planned to use to make trips at highway speeds. You might "get by" with it, but it's not the safe way to do it. The following link is to the TireRack FAQ on this subject:

P metric tires are not for towing ....period. Call the manufacturer,the sidewallls are not reinforced to handle the weight. I ran into this problem with a brand new 1/2ton Chevy truck ,tire manufacturer said no , gm corporate said yes

Nonsense. The weight capacity of the tire is included on the sidewall markings. If your tire is rated for 2,100 pounds, then it doesn't matter if that is a P-Series tire or an LT tire or a "real=truck" tire, it's designed to handle up to 2,100 pounds - regardless of whether those pounds are people, cargo, or hitch weight.

I was told by the manufacturer absolutely not to tow anything. I'm went with the company that made the tire not the corporation or people that said it was ok to tow with them.

Anyone can choose to do what they want, but when the chance arises someone could be killed I'm always going to go by the manufacturer's statement, they make the tire.

Well---
I'm only on my second TT and second Dodge 1500 TV, both have had P rated tires and never a problem, just thinking of upgrading a little.

Plus if the tongue weight is 800# isn;t that all the increase weight onthe tires is ?????

Sorta. If the tongue weight is 800 pounds, then with a good properly-adjusted weight-distributing hitch about
400 to 480 pounds (50 to 60 percent) goes to the rear axle of the tow vehicle (TV)
160 to 200 pounds (20 to 25 percent) goes to the trailer axles, and
160 to 200 pounds (20 to 25 percent) goes to the front axle of the TV.

If you don't overload the TV over the GVWR or rGAWR, then you won't overload the stock tires.

I've always mixed LT and P on 1/2 ton trucks as does/has the rest of the world.

I've used LT load range C and D tires on the trucks rear with P on the front. No handling issues or odd wear issues.
Currently have LT C on the rear of the wifes 1500 crew cab chevy. When I get all of the OEM P tires wore out then I will go all LT C tires.

When towing my best tire is on the front.
Getting a tire failure on the front is very dangerous. P tires are for passenger and load them and have a failure. The truck fender goes with it. While a failed LT tire sidewall is so strong that it only vibrates and does not blow.
I know because I have cut both types.
I say it again. I would not tow with the junk tires that are on 1/2 tons today. Load range C is plenty.
Same goes with the junk ST tires that ruin trailers today.

I agree and again say just not worth the $ or a life to put a load on p metric tires.
