Just did a 430 mile travel day. I had put on Carlisle HD tires and upgraded from tow max D to E rated. Had them balanced and added a tire minder TPMS. As far as towing I did not notice any difference in towing or fuel mileage for better or worse. Speeds where 60 to 65 almost the whole way. I had the tires set at 78 psi and found after about 10 miles on the freeway they went to 81 to 84 for the whole trip. Outside air temps were high 30s low 40s. There temps were almost always only a couple degrees higher than the TV shown temps. I did have a TPMS problem at about 60 miles traveled. I had a alarm showing psi at 74 in 1 tire and the red light came. Alarm was easy to hear and got my attention. It quickly went back to normal psi and was fine the rest of the trip.

Yes it is. That false alarm was also good. I had wondered if I would hear it over the tire, engine, wife noise. So it worked I heard it looked towards the unit and seen the red light was on. I was slowing picked up the unit and read the psi warning as it than went back to 81 or 83 psi. Drove to the next pull out and looked at the tires as all was fine.

Was the "base" pressure setting set up? Should allow a % above or below baseline before triggering an alarm.
A % above or below will trigger the alarm, but also a rapid loss of air will trigger it, I believe 5psi within 15 seconds. If it was reading 83 and then suddenly read 74, the rapid loss would set it off.

They were set at 78psi cold. The alarm had to be a false since as it went off I picked it up right away. Looked at it, seen the 74psi, as I was holding it, it went back to the 81 or 83 psi. I did not reset or cancel the alarm it did by itself. That's why I continued and did not stop at the time of the alarm.

I see a lot of postings about the Carlisle tires I was thinking of upgrading from the stock tires on my 2015 Montana from the ST 235/80/16 E 10 ply to ST 235/85/16 F 14 ply with a max of 110 PSI has anyone made the same change? And any comments on the right tires?
Carlisle tires or?

Just make sure your wheels will do the 110 psi thingy... Mine wouldn't... But I have roughly 2K miles on my ST235/80/16E Carlisle HD and couldn't be happier... they made a huge difference in how the trailer pulled....

I checked that 1st before looking for tires, these are my wheels and 110 PSI Max.
16" Aluminum T07 Trailer Wheel. The exact size is 16" x 6" 8 lug on 6.5" bolt pattern. Center hole diameter is 4.9 inches. Max load is 3750 Lbs per wheel. Most common tire sizes mounted on this wheel are 235/85R16 and 235/80R16.

I just went on a 400 mile or so round trip with my new Carlisle tires. I couldn't feel or tell any difference in towing and didn't get any difference in fuel mileage. But that said I did feel a lot more comfortable with them on there and the old Trailer Kings gone. They were 3 years old with no more than 3000 miles on them and one was obviously going bad and a second we found was separating with a nice bulge in the tread when they took them off. Replaced just in time. Got them for $77 each at Wmart and mounted, balanced and installed for $15 each at a truck and RV tire shop. Now I shouldn't have to worry as much every time I pull out to go someplace.

Besides Javi's comment, Keep in mind that the Carlisle ST235/85/16F HD is a inch larger in diameter than the ST235/80/16E HD. Some members had concerns of being a half inch closer to surrounding structures and therefore went with the 16E. I selected to go with the 16F and have no concerns with clearances, great tire and Yeap heavy guys

The 85 E AND F are an inch larger than the 80 E. My tire guy said he would have talked me out of putting them on if I went with the 85s when he saw what we had to work with. I had talked to him before I made up my mind and after I told him the clearances he said I should stick with the 80s. Just check your clearances, on BOTH sides. They are not the same from model to model or year to year so don't just go by a posting on a forum.

Thanks for the clarification, should have stated 80 to 85s. Lack of a folding ladder throws you off at times

Yes another good point but I checked that 1st and have lots of room only one tire is close, front right side tire and that 4 to 6 inches away

Carlisle tires or?
Just for the record, Carlisle Radial Trail HD tires ST 235/85/16 F 14 ply don't exist. The ST 235/85/16 F is a 12 ply tire with a maximum pressure of 95 PSI and a maximum load rating of 3960 pounds (when used as a single tire) and 3520 pounds (when used in "dually" configuration) <that's 4 tires on one axle, not two axles with two tires each>.....
To my knowledge, Carlisle doesn't make a ST tire in the 235/85/16 size that is rated 14 ply.
Now, for some numbers: The current tires on your trailer are ST 235 80R16 LRE (10 ply) rated at 3520 each or 7040 per axle. The LRF (12 ply) tires are rated at 3960 each or 7920 per axle. Upgrading to the 12 ply tires would increase your "tire capacity" from 14080 pounds to 15840. That's a 11% increase in tire capacity, although your axle rating isn't increased because of other factors. Your wheels should be rated to carry that load/ at 95 PSI pressure, but you'll need to verify that fact.
If you are considering 14 ply (LR G) tires, Sailun manufacturers the S637 tire in ST 235/85/16 G (14 ply) and is available for around $125-150 per tire. They are load rated for 4080 (or 4400) at 110 PSI. They require a special rated wheel to carry the increased pressure.

Sorry my mistake I was looking at Gladiator tires at the same time.

Maybe the best for me is the Carlisle Radial Trail RH Trailer Tire - ST235/85R16 F 12 Ply 95 PSI Max. than I will be in a save range for my wheels also.
I am getting ready for a 3000 mile trip in a few months up north from CA

Someone correct me if I'm wrong, but the RH tired are the old model and the HD tires are the new style. I'm not sure when they stopped making the RH tires but I'd be careful on how old they are if they've been sitting in a warehouse for a couple fo years. You can get the LRF 12 ply in the HD tires as well.
Darryl: I just upgraded my 235/80/16 LRE tires to Carlisle Radial Trail HD 235/85/16 LRF. I had Rainier brand tires on mine. No problems with the Rainiers, just wanted more piece of mind. Got mine from Walmart.com. at $94 per each. DOT dated 52/16 so about 4 months old. Shipped to the store. No problems mounting them on my High Country. Couldn't believe the difference in the side walls from the Rainiers to the Carlisles which appeared to be much more robust. I had mine mounted and balanced then took them home to mount on the High Country. Just a personal choice. Be ware if you do the same, these suckers are really heavy.
