New Tires for the Ram 1/2 ton

After some research and advice and me thinking that E rated would be overkill for the 1/2 ton the OEM 275 55R20 XL tires will be replaced tomorrow with MICHELIN
DEFENDER LTX M/S LT265/60R20 121/118R E rated. I know it won't be enough to get JohnD10 to ride with me but I am trying.... My friends brother will buy the OEM tires from the Ram to cover some of the cost. Took the rig out 6 times last 2 weeks and I am convinced the tires are the soft/weak spot ... We head out Thursday afternoon first camping trip... less than a hour to my daughter's Campground.. as always appreciate the help from the forum... Thanks Frank

Following closely. Replacing tires on my Ram soon before 4500 mile trip with my 233s in July. Mine are 17 inch rims though.

I have a set of those on my Ram 1500 now. I have run 275/60/20 P series, 275/55/20 XL loads and the 265/60/20 E loads. Overall I like the 55 series XL loads the best but have noticed some difference when at around 8k on the truck IE practically speaking maxed out. I transport Forrest River TTs and also have a GN & Andersen 5th wheel adapter.

I checked out your trailer on FR's site. Practically speaking that is a little too much trailer for your truck but may work ok locally in the flats with reasonable speed. I have not read your posts on it. Do you have axle to frame bags?

I did transport a 37" ball to bumper 9,100 pound 3 slide Wildcat Maxx from the Dallas OR plant to the LA area. Slip was 3,300 on the steers 4,440 on the drive and 15,800 CVWR as I had tools hitches full size spare etc in the bed. Not sure about your 5th gen but the 4th gen max CVWR is 15,950 so getting up there.

Went down the 5 so up and over 5 & 6% grades past Mt Shasta in north Cali and up the grapevine into the LA area. No handling or sway or stopping issues. No issues controlling speed coming down the grades but I have the Ecodiesel with tune which has the addition of an exhaust brake that works with the factory transmission brake and tow haul. Truck also had optional TBC trailer brake controller so I could easily control or keep the same down hill speed without even using the truck service or foot brakes to control speed.

Let us know of your experiences questions and decisions. I did post awhile back of a guy who double tows a 5er and small boat on here with pics behind his Ecodiesel. But If memory serves me his CVWR was not any more than yours and his pin weight less.

Howdy neighbor. Right down the street in Port Charlotte. That looks like a lot of trailer for a 1/2 ton. Not into towing. Mine is on a season site in MA. I just never see much support on this site for 1/2 ton towing a 5th wheel. It's good for Florida flat country buy hill climbing and stopping may be problematic. Put some good rubbor on the trailer while your at it. OEM trailer tires are junk.

Vern Thanks .... Truck pulls straight and stops great ... I will be 90% FL/GA travels .... the 2019 RAM has been upgraded 4 inch longer wheel base, larger brakes, 6 lug wheels and stronger suspension ... no bags yet squat is little over 2 inches my brother in-law put some on his 2014 RAM short bed and he says they are great (Airlift 1000HD) I will probably put some on... I have been towing for 25 years, 28 ft 8,000 lb lawn trailer with Ford F 250 ... there is a bias for any towing using a 1/2 ton and I am OK with that... I have been out with the rig 6 times last 2 weeks and the tires are the weak spot on this set up .... first trip tomorrow 55 minute ride to my daughters, she works/lives at a campground , most of our trips will be under 3 hours...

10 ply's no roll with my 5ver.


the original tires and rims shown on the second image are replaced. saving them for trade in with 6 thousand miles on them.

Frank I believe at only 3" ie at less than an inch of travel you are at the factory bump stops on the 5th gen. Steve Smith owner of Timber Grove air solutions could tell you off the top of his head. I have been using axle to frame air bags for 5 years 540k miles transporting TTs & boats on my 4th gen Ecodiesel.

The axle to frame setups support control & dampen the rear suspension so that it is road compliant over grooved and pot holed curves as well as comfortable riding. Used the cheap thin plasticky in coil bags with cheap plastic lines and fittings that leak on two vehicles in the past. Having experienced the difference of a large heavy rubber low 15 to 20 psi bags dampened controlled ride vs the 30 to 40 psi bouncy ride of the in coil bags I will never go back. Not for $100 vs $360. Brass fittings better lines they don't leak nor pop out.

Honestly this will make a bigger difference for you than the tire upgrade. BTW you don't need an expensive on board compressor system. A cheap mini compressor from Harbor Freight or WM that you stow under your seat will lift it quickly and easily as you are only pumping in from say 5 psi unloaded to 20 psi with trailer. Make sure you have enough cord or hose to reach where you put your air valve. Lots of people put it behind the fuel fill door which is both clean looking and more convenient than by the license plate when you have a trailer. Also most truck stops still have free air and plenty of room to maneuver.

not getting into the half ton vs 3/4 ton debate, but I replaced my Ram OEM tires with the MICHELIN DEFENDER LTX tires. I have been very happy with the upgrade.



My 5th wheel is 29ft and loaded under 9500 lbs

neither was I. my Ecoboost with the 10 plys hauled well and I had the Airlift 5000 airbags installed as well for less dipping. my 5th wheel toy hauler loaded with the SXS is just over 11,000 lbs.


if you find that you still need more control get a set of Airlit Load lifter 5000's for the RAM

amazing rebound control
