Changing out PS tires to LT tires? Help!

[Sheripoms]

We have a 2008 Tahoe. I need to change out the ps tires to LT for towing. Am I right in that I just need the LT tires on the back? Can I keep my ps tires on the front?
Also which Lt tires would you recommend? I heard Michelin is good.
Thanks!!!!

What is a ps tire? Or do you mean "P" Metric?
NO, you should never use different types of tires on a vehicle.

I would have all 4 tires the same.
If you want to put your vehicle to work set it properly. I see to many odd setup that people tell me. Just because they want a Cadilac ride.
Cadilacs make pour towing vehicles so stop worrying about the ride and setup your truck to work.
LT tires are the best and will deliver much more satisfactory towing then the cheap P tires that are on todays truck.
Our nefew went for a ride in the woods with his brand new 4 x 4 GM and could not return, had to walk back. Blew 2 tires, within 5 miles

From a basic google search:

Tires | Goodyear Tires
Tires | Goodyear Tires
Goodyear Tire and Rubber Company
Metric, or tire type, defines the proper use of the tire. For example, a "P" designation means that it is a passenger car tire. An "LT" designation is for a light truck.

All four need to be LT.
Making the switch to LT tires can make a huge difference.

Asking about brands is like a Ford Chevy Toyota debate.
Goodyear Wranglers on our pickup and Michelin on MH.

I am new to motorhome. I got a naive question; Is there such a thing as "MH" tire? (MH = motorhome). My reasoning is: Motorhome normally sat around; they get dry rotted. Whereas "LT" light truck normally get uses the thread wear out by the time the tire began to rot.

Is there some kind of dressing we can apply to MH (MH=motor Home) tire so it can hold up the weather element? Tire get replaced because it is worn out - not because it sat around too long.

Nope. Depending on size you could be looking at truck tires.

Yes, sorta. Michelin makes the XRV tires for Class A motorhomes and Class C mini-motorhomes. That's a Michelin X tire designed for RVs (motorhomes). Class A usually has 22.5" wheels. And Class C usually has 19.5" wheels. The XRV comes is two sizes of 19.5" and three sizes of 22.5".

I'm a Michelin fan, so I haven't looked at other brands. But I'm sure Goodyear, Bridgestone and others have the right sizes of truck tires that will fit a motorhome.

The "weather element" you should worry about is ultraviolet (UV) light rays. Snow, rain, heat, cold and other weather elements won't hurt the tires, but UV rays can kill them long before their time.

Your best bet is to cover the tires with a heavy tire cover designed to prevent UV light rays from reaching the tires when the motorhome will be in storage for more than a few days. RV stores including Camping World sell those tire covers: Note the following link might not be the right diameter for your tires, but it will give you a good idea what you're looking for:
