Anyone have experience with OTR tires on class A?

In recent searches for tires, I have come across several over the road type semi tires for steer as well as drive applications. The size as well as load bearing are similiar or exceed the typical Michelin/Toyo replacements. Price is much cheaper. Has anyone had any experience with this type tire? I mean if they are put on a 18 wheeler surely they will last on a 45í bus as long as load tolerance is taken into consideration, right?

Over the Road truck tires are designed to have long tread life. RV tires are designed for ride comfort. You can use either but you won't enjoy the ride or handling as much. On our work trucks we run some cheap $300.00 Chinese imports because in the scrap metal business tires don't last long. I would never ever consider running one of these on my rig when a good Toyo is around $425.

We are running the Dayton D520S on ours and love them.
Local tire shop sold me on them based on the amount of use they were really going to see. They initial aired them to 120 and sent me out the door, rode nice but a little stiff so I dropped them to 80 which is what the coach calls for (without weighing anything) and its rides so much smoother.

Certainly you should weigh and compare the weight to the TIRE's pressure chart. The RV has no recommendation on tire pressures for a Dayton, which is what is important. The RV was equipped with a particular brand / model tire. Any recommendation was for that tire, not the Dayton.

We had OTR tires on our rescue engine at the FD. They lasted one year...not due to the tires wearing out, but the stiff ride shook so much of the rig going down the road, the transmission had to be reprogrammed, computer replaced, exhaust replaced, and driveshaft bearings and joints all replaced. We ended up having to switch to the only other tire being made for it...Michellin tires. The steer tires are actually dump truck steers. We thought oh boy here we go again, but they are great!

OP, not sure why you’re replacing tires on a 2016 DP.... are those Michelins already cracking? With 365s on the front, pretty sure Michelin is the only maker and it’s not a RV tire. No reason to buy overpriced 315 Michelin for the rear... plenty of other good manufacturers and I doubt you’ll find a 315 in a RV tire,

Now there is some difference in local and long haul tires with local having more rubber on the sidewalls.

We got ours with new Samson OTR truck tires. Three years later the one front started to show sidewall cracking so I replaced the fronts with Sumitomo tires. HUGE improvement so next year I'll replace the rears. Both ride quality and noise was improved and they were a reasonable price. The truck tire shop said they never seen Samson on the front of an RV they are mostly trailer tires.

Bought 6 Samson tires (China-made) 3 years ago. Cost for them was about $1400. So about $233 each. Have put 10K miles on them thus far, zero problems other than picking up a nail in one tire. The ride was palpably better than the Michelins they replaced.

those So called rv tires are just tires with size specs like michelin made to make people think they need them.. do really think a truck driver doesnt get the best riding tire he can?? i drove OTR and cement and dump trucks and delivered regiona. ect .. read this pdf about tires and tires for correct situations. to many rv's just get what the sales says...

Michelin measures their tires different than every other manufacturer. That is why most RV tire sizes only show Michelin having that particular size. Other manufacturers have that same size tire but it will have different numbers on it. Any qualified tire shop can cross over most any Michelin tire to another brand. Iím currently running Firestone H rated steer tires on all six wheels. They are definitely firmer than the Michelins but by weighing the coach and fiddling with the pressures, I was able to achieve as good or better ride than the old cracked Michelinís. Iíll let you know in a few years how well they last.

I’m using Toyod and they don’t ride any different than my Michelin RV tires.

I have Sumitomos here too (22.5"). They were what was on my rig when I bought it last year and were two years old at that time. I haven't had another brand on yet to compare to but they seem to ride fine and I haven't had any problems with them.
