Michelin LTX M/SII are great. Quiet and good MPG. 60,000 mile warranty.
I did get Goodyear Silent Armours for the winter though. They seem to be real good as well on the road. Not noisey at all.

Get rid of the P rated for LT and then you get rid of that RIDE.. Not me.

You ought to check facts before you make those kind of statements. My Ram came with the Goodyears P26570R17 SRAs and the tires have a 115 load index. Each tire can carry a load of 2679 lbs. Multiply that by 4 and you get a load carrying capacity of 10,716 lbs for your truck. the Ram 1500 is only rated to carry 6,800 max. So you have almost 4,000 lbs excess capacity, besides the tires rating are conservative. Many LT truck tires are rated no more the the P rated ones and are not rated as high in the speed ratings. The sidewalls maybe stiffer on the LTs but they are not really needed unless you are rock crawling on some sharp rocks. Another thing, the ply rating is just that, a rating, an 8 ply rating does not mean they are made out of 8 plys.

What is the whight of a ram 1500 quad cab 4x4? est 5000 pounds ( tires have to support this all the time) add your 6800 pounds to the whight of the truck and you get 11800 ...

as 80% of a trucks load is in the rear, you can't expect the front tires to carry any thing but the front end ...

P rated tires are fine on a passenger truck with light loads ... P = passenger.

Ha!, Ha! Are you kidding me? The GVWR of 6,800 lbs is the weight of the truck, gas, passengers and cargo. Just go and try to load 6,800 lbs on the bed, it would take a 5 ton rated truck for that.

Another thing, the Ram CC weight distribution is about 54% to 46% front to rear, so this 80% business is totally hogwash.

Here is technical bulletin from Nitto tire,, which by the way make P rated Terra series tires

TECHNICAL BULLETIN
Replacing Tires on Light Trucks
Any replacement tire on any light truck must be of a size and load range that will offer equal or higher load carrying capacity compared to the original equipment (OE) tire on the vehicle. Furthermore, the ability of any tire to support a specific load is solely based on the inflation pressure within the tire, and the maximum load and inflation capability of the tire. Even tires with the most robust design and construction will fail in service when under-inflated.
For purposes of this bulletin, light trucks include sport utility vehicles (SUV), pickup trucks, hybrid SUV/pickup trucks, minivans and any vehicle designed as a multipurpose passenger vehicle, truck, bus, or trailer. Many light trucks today are equipped with P-metric tires as OE. Other, more heavy duty trucks may be equipped with LT-metric tires as standard equipment. Nitto Technical Service is aware that some tire
installers promote the replacement of original P-metric tires with LT-metric tires as a more "heavy duty"
alternative,

for example:
Original Tire: P265/75R16 114
Replacement Tire: LT265/75R16 Load Range 'C'
Warning!
Load Comparison Example, P vs. LT:

P265/75R16 114 Max Load = 2,601 lbs @ 35 PSI
In order to carry the equivalent load, a LT265/75R16 Load Range C must be inflated to 50 PSI. Using this example, even LT265/75R16 Load Range D, or E must be inflated to 50 PSI to carry the P-metric load at 35 PSI. LT tires do not offer any benefits of being "heavy duty" when under-inflated. Replacement Tires Must Carry Equivalent Loads: If you replace a P-metric original equipment tire with an LT-metric tire, it must be able to carry the equivalent load. To find the equivalent load, refer to the Tire and Rim Association Yearbook and find the load of the original tire according to the PSI shown on the vehicle's tire information placard. Then refer to the 'Light Truck' load and inflation tables. Apply the PSI that corresponds to the required load of the Pmetric tire. See the last page of this bulletin for additional information.

Heat Build Up Example:
The enclosed photos were taken with a heat sensitive camera, and show the sidewall temperature of a running, loaded LT-metric tire. The two photos represent an LT-metric tire at 30 PSI (cold), vs. 50 PSI (cold), at equivalent loads. The temperature scale runs from 95° F (blue) to 122° F (white). Please note the considerably higher running temperature of the "under-inflated" (30 PSI) LT tire vs. 50 PSI. Any increase in the tire's running temperature will have an adverse affect on the long term durability and safe operation of the tire. Please note that size-for-size, LT-metric tires require higher air pressures to carry equivalent loads of P-metric tires, and that any failure to adjust air pressures to achieve the vehicle’s load requirement will result in tire fatigue and eventual tire failure due to excessive heat build-up. Due to the higher PSI requirements of LT-metric tires, they may not be suitable for replacing O.E. P-metric tires because of the ride harshness that results from higher PSI requirements.

P-Metric Tires on Light Trucks Have Reduced Load Rating:
When a P-metric tire is installed as OE on light trucks, the load rating is reduced by a factor of 1.10 by the
vehicle manufacturer. This load reduction is mandated by Federal Motor Vehicle Safety Standards
(571.120). The reasons for this include the expectation that P-metric tires which are designed mainly for
passenger cars, may experience more severe service on light trucks.
Example - P265/75R16 114S:
Tire and Rim Association Yearbook load tables show 2,601 lbs. Max. Load at 35 PSI. If this tire is fitted to
light trucks however, the load(s) are reduced by a factor of 1.10.
For example: 2,601 lbs. Divided by 1.10 = 2,365 lbs. (rounded) at 35 PSI.
Therefore, if a light truck is fitted with a P-metric tire as O.E., the load at any pressure is reduced by the
1.10 factor. Using this example, a light truck fitted with P265/75R16 114 as O.E., requiring 35 PSI
according to the tire information placard, is actually accommodating a load of 2,365 lbs, not the maximum
load for this size of 2,601 lbs.
Replacing Original Equipment LT-metric Tires:
If you replace an O.E. LT-metric with another LT-metric size, it must carry equivalent loads. Inflate to the
pressure required on the vehicle’s tire information placard.
If you intend to replace an O.E. LT-metric tire with a P-metric tire, check the load requirements carefully.
Many times, the P-metric tire does not offer enough load capacity. Also remember that you must
reduce the P-metric loads by a factor of 1.10 when replacing O.E. LT tires.
Replacing Dual Tires on Light Trucks:
Nitto does not recommend that P-metric tires be used to replace LT-metric duals on light trucks.

Tires must never be operated in excess of their rated speed limit. Exceeding the tire's speed capability will cause overheating of the tire and sudden failure, possibly leading to loss of vehicle control. Nitto passenger and light truck tires have a maximum speed rating depending on size
and type. Consult your tire dealer or contact Nitto Tire @ 800. 648.8652 if you are not sure about the maximum speed rating of your tires. Nitto Tire North America, Inc. does not endorse the operation of any vehicle in an unsafe or unlawful manner. Tire speed ratings do not imply that a vehicle can be safely driven at the speed for which the tire is rated. Speed ratings are based on laboratory tests that relate to performance on the road, but are not applicable if tires are underinflated, overloaded, worn out, damaged or altered. Tires Installed on Vehicles with Modified Suspensions and Increased Ground Clearance. Consumers should be aware that the installation of off-road type tires combined with modified suspensions and increased ground clearance will significantly alter the handling characteristics of the vehicle, and may result in increased braking distances as well as significant changes in vehicle maneuverability and handling compared to the factory-equipped vehicle. As with any vehicle, Extreme Care must be used to prevent loss of control or roll-over during sharp turns or abrupt maneuvers. Always wear seat belts, and drive safely, recognizing that reduced speeds and specialized driving techniques may be required. Failure to drive this vehicle safely may result in serious injury or death. Do not drive this vehicle unless you are familiar with its unique handling characteristics and are confident of your ability to maintain control under all driving conditions. Some modifications (and combinations of modifications) are not recommended and may not be permitted in your state. Consult your owner's manual, the instructions accompanying this product and state laws before undertaking these modifications.

I have never been a fan of the Wranglers for as long as they've popped up on Chrysler products. I won't go into a list of reasons why, but i'm sure you have your own similar reasons. I run the Michelin LTX. A sweet freakin' tire! Will be getting my 4th set in 11 years next Spring. They have never given me issues in all these years. Even when I wasn't so religious with my rotations.

54 % to 46% is on a unloaded truck, Im not buying that the ram cargo cap. when maxed out is 54% to 46%, Run your P rated tires if it tickels you in all the right places.

My intial math thier was a bit goofy but the moment that you take a 1500 Ram into the work truck world, or brand A B C, up to the factery numbers, your running on borrowed time, your not going to find half ton work trucks in the real world lasting on P rated tires on road or off road, no matter what said tire brand says load cappacity is.

Ford on my 04 F-150 run 2ply hancook tires, p 235 70 17, Im not crtical of dodge on this topic, all 1500 pickups run Passenger rated tires, so tickle your self with the warm and fuzzy P rated tires.. If your a typical truck wanna be and dont make a habbit of maxing out your cargo, P rated tires are fine for home depot, for a 100% work truck P rated tires will not work out well for anyone.

This is were I have issues with truck brands, thier selling you more than you need, because most people will never use a 1500 to the max cargo limits, so yup, P rated tires are the cats meow, or the best compramise...

I repspect Nitto, they make great tires, I own a set on my 2500 Ram, but I have never owned a 1500 pick up that was used in a passenger mode, they were work trucks right from new, and p rated tires were replaced verry quickly with LT rubber If I bought a Ram 1500 today, the 20 in Goodyears would be instanlty replaced with 17 in tire and rim ( 1500 rim) with my New 10 PLY nitto tires.

I use my trucks for work, play, not for driving down the road so I look pretty !!
