Lt Or P And Size Change?

[Turbine tester]

Ok I'm putting on some michelins (LTX m/s2), my truck is a 07 sierra 2wd (non classic) it came with 245 70 17, I think I'm going to go with 265 70 17 do I want to go with the LT or the P?

I do hall a 27 foot camper with it so what can you experienced truck and tire guys tell me.

If planning to haul and tow, go with the LT. LT stands for Light Truck, P stands for Passenger. Check the ply rating on the sidewall to get the load rating. When hauling and pulling I would look for at least a C rated tire. A D or an E would have even more load carrying capacity which means they will be a stronger built tire (comparable strength as a certain number of steel belts and fabric belts) and also an ability to run higher air pressure. Most 3/4 ton pickups and especially the diesels will come with an "E" rated tire and can run about 80 lbs of air pressure. This is necessary when pulling say a 5th wheel trailer around 15,000 lbs.

 

So calculate what your truck and trailer weighs and buy the appropriate rated tire for the job.

 

Here is some good info:

LT rated tires will have less side-wall play as compared to P-rated tires, even though some P-rated tires can carry the load.

On my '02 YukonXL, I switched to LT tires as I used it to tow often, and it made a huge difference.

LT tires of course will ride a little firmer than a P-rated tire, but it will tow better.

yes, I agree with the previous posts... you have a truck, you want to use it as a truck, so it is good to put truck tires on it..

 

as mentioned, some P-rated tires will handle the load capacity requirement ... but the LT D-rated and E-rated tires have much stronger sidewalls and tread base providing a much more stable experience when pulling a trailer...

 

GM puts these P-rated tires on because they ride a softer ... (and they are cheaper).. and they do a good job for many people who use their trucks as lighter duty use. IMO

It's difficult to find LT-C tires, but LT-E are usually offered for just about every make/model truck tire. I'm pretty sure you can run LT-E at the same pressures as LT-C. I plan to use LT tires on my truck when the P-tires wear down, but I've been unsure about what to expect from the C vs E rating. From what I've read, the Michelin MS/2 is a softer tire than many, so a "E" rating at ~45 psi should still ride smooth when not towing and not wear odd (bump up to 55/60 when towing). I don't know the rating on my stock rims (I'm guessing they are rated for 60 to 70 psi, but will check inside when changing tires). Then again, tiny bike tires/rims run 65 psi, so go figure.

Go for the LT. Even a P-rated in a T or H speed rating will vastly improve the handling of your truck. Changed mine (P-265/70/17) from a 113S-rated to 115T-rated. The change in steering response from the extra strength in the sidewall is like night vs day. Drives like an entirely different vehicle.

I have p rated tires on my 2wd Sierra, and I severely overload it once. I have never had a problem with the tires, but could have used some more brakes! I had 44 railroad ties on a trailer, and in the bed. I have since upgraded to a P-rated tire (Hankook DynaPro ATM rf10) that has a better load range (2535 lbs/per tire) It depends on your application. A P rated tire will be lighter than an LT, and give you better fuel economy. P-rated tires are also less expensive. The manufacturer put the P tires on that truck saying its capable of the duties described in the owner's manual. If you are overloading the tires you are overloading the truck. jm2c.
