it'd be interesting to know if they were the BASE tires or an 'upgrade' ? MFRs pull 'tricks' to upsell everything they can to make more profit. Frankly it's crazy what some spend on 'tires and rims' for their 'rides',specially the guys who never ,ever go offroad with their $$$$ 4wd trucks.

I know exact replacements were over $1400 for a set of four.

You're right Jay . When I bought my truck the dealership had several sets of tires and wheels off brand new trucks that the buyer replaced with bigger ones .

I looked my sons trailer over today, it used to be mine. The tires on it are 20+ years old. Even though they have good tread depth, there will be 4 new 700x 15 Multi Mile trailer tires on it by 5:00 tomorrow night.

Many trailer builders are notorious for installing Chinese tires and having an optional upgrade to better quality tires. A lot of people look solely for price when buying a trailer, so the dealers don't get the upgraded tires.
When I bought my Montana fifth wheel it had (Chinese) Trailer King tires on it. It had about 1,000 miles on it and I was checking it over and found tread separation on one of the tires. (Did you ever see how much damage a blowout can do to a camping trailer?) I now have four Goodyear Endurance. They weren't cheap, but I feel a lot better with the Goodyear's on it, than I did with the Trailer Kings.

one thing for sure, whatever is 'stock', will be the cheapest thing to be put on by the factory.
Factories always work off PRICE FIRST... If you want a tire that is rated at 3200# for a F350 then you look at all the possibilities... Maybe Goodyear and Firestone are your only options.. Who ever has the BEST PRICE gets the bid "normally"..... Are there CHEAPER TIRES ? SURE.... Do they meet the SPEC that the manufacture wants ? NO... If they did, they would be one of the suppliers.
Tires on cars are not as critical as they can normally be rated at 1600 or 1800# load.. You see a LOT OF NAMES on car tires that you never saw 20 years ago.
here is a list of tires sold on AMAZON for newer cars .... if you have a newer CAR,, look at the factory tire Manufacturer... Some you have never heard of.

I don't agree with that either Jay.
The truck I have now 2016 F-350 SRW came with Michelins that I took off at 55,000 miles and were still legal, but I wanted new tires before winter.
The F-350 dually that I had before had BF Goodrich TA's. I got over 90,000 miles on the rear tires and over 60,000 on the fronts.
I wouldn't call either Michelins on BF Goodrich TA's cheap tires !

I think on "TRAILERS" it depends on what your trailer is used for... A 2-3 axle camper or a 10K car hauler that travels thousands of miles, and / or hauls 9- 10K loads all the time should have ST tires..
If you have a utility trailer that you use 5-6 times a year to go to Menards to pickup lumber, or haul a couple 4 wheelers to the farm to play, then P rated tires are probably fine for that application.

Not all pickups have LT tires... Maybe 3/4 ton "MOST" have them... But in 1/2 ton, 75% of the trucks sold have P rated tires on time... There are a LOT of new trucks sold with 18 and 20 inch tires 60 / 50 series and they all are P rated tires.. many rated at 2500 pounds per tire or 10K total for a 1/2 ton truck... WAY more than needed.
If your tire pressure is 35- 50 psi, you probably have P rated tires.. If your tire pressure is 60- 75 psi, then you probably have LT tires.
These are your options on a F150...... an F250 would probably have all LT size tires.

I don't know which "pickups with 'P' tires on them...straight from the factory....." you are talking about, but I know it's not Ford or Chevy.
I have a new Ford truck on order and I was wasting some time at the dealer (waiting to talk to the service manager) when I first saw your post. I walked out and took a look at all the F-150's and every one of them had LT tires.
When the service manager got there, I asked him about it and he said he had never heard of a new truck coming in with P tires. He worked at the Chevy garage before coming to Ford and said the Chevy's were all LT tires, too. His logic was that the truck had weight carrying and trailer weight ratings and that P tires wouldn't be adequate and would leave the manufacturer open to lawsuits.
I didn't check Ram, Toyota or Nissan, but I assume they are the same.

re: So, with your logic we could put implement tires on anything and drive it safely at any speed
no NOT my 'logic'. Never bought an 'implement' tire,but 'logically' they have some kind of 'speed' rating,so as long as you go slower than that you should be fine.
Make me wonder, and you farmers will KNOW, are there 'on road' and 'off road' rated implement tires ? Would sure hate to be behind a wagon train of haybales on the road IF the implement tires had NHS molded into them.
There was a discussion years ago here of someone using AIRCRAFT tires on their wagon or grain hopper. If I recall, they were cheaper and had better specs than 'implement' tires.
My comment was that since 'P' rated tires are 100% OK for a pickup hauling 1000# of stone, then they SHOULD be 100% OK for a trailer hauling 1000# load of gravel. If, IF ,they're NOT safe then someone better strike a law PDQ, cause there's a LOT of pickups with 'P' tires on them...straight from the factory.....

I feel the problem is making something that is just barely good enough to last to get you out the door of the store.
I have a 2 ton truck (1975 model) I bought 15 to 20 years ago. Four of the tire on it now where there when I got.  Just shows I don't drive it much. Thankfully they are old tires made before the rot away in 7 or 8 years.
Not being a engineer I have no idea what all would be different in a Lt and St tire, but sure hope if it has load rating to carry the load it is not boom waiting to go off if misused. I can see the side wall thing and the St lasting better on a trailer. But there are many trailers running Lt's out there. I bought one that way, have not used it as I thought so I have only changed one tire on it.

So I guess what engineers do is only to make money? So, with your logic we could put implement tires on anything and drive it safely at any speed. It's people that think like this that that have accidents and hurt or kill innocent people.
The reputable tire companies have a lot of liability. That's why they design and manufacture tires with specific ratings for their intended purpose. Unfortunately, there will still be people that think that as long as the tire fits on a rim, it can be used for any purpose.
By the way, I have ST tires on all trailers, LT tires on my truck and P tires on my wife's car.

I've always found it 'interesting' that some say 'gotta use ST tires on trailers'. say you're hauling 1000# of gravel,well within the load specs of the tires... I can haul the same 1000# of gravel in my pickup with P rated tires....and THAT's OK ??
curious am i ..
I don't see how an ST tires can't be used as a 'sterring ' tire. I KNOW I make real tight turns backing up my trailer, far tighter that the truck can ever do,so just how can an ST tire fail up front ?

I do not buy the 'No Name' Chinese junk, I have Coopers on one trailer and Bridgestones the other, all ST. Tire Dealers will explain do NOT have to honor warranties if used on other than Recommended applications.

Trailer Towing – ST Tires vs. LT Tires | RV 101 your education ...Nov 8, 2012 — ST tire designation: ST stands for Special Trailer tire. ST tires are designed for use on trailer axle positions only. ... Because of the heavier construction for an equal volume of air space, an ST tire is designated to carry more load than a P or LT tire.” LT tire designation: LT stands for Light Truck tire.

Doug, I’ve been running car tires in my tandem axle utility for years. I don’t haul anything over ~3,500 pounds. It does great.
A little rim/tire shopping secret. Once you know your rim bolt pattern, Google what cars/trucks used that setup, go to pick and pull and look for the Spare tire. I’ve found like new tires/rims still in place underneath truck beds.
All that said, I also wouldn’t mind putting on trailer tires.
Not fun having tire issues when under a load.

Yup,get rid of the maypop used P tires,, nothing beats hearing a kaboom and seeing your trailer fender go 50 foot in the air and what's left of that tire beating the side of your tractor.
