Members widely recommend Sailun tires for heavy fifth wheels, with many reporting years of trouble-free use, especially when purchased online and installed at local shops. However, some caution about recent manufacturing shifts (from China to Vietnam and now Cambodia), noting a recall and quality concerns with certain batches. The latest Sailun S637 tires are now Load Range H (16 ply, 120 psi max), replacing the older G-rated (14 ply, 110 psi) models. Members stress the importance of...

I purchased a used 2024 Montana High Country 295RL and have put about 2k miles on the Ranier tire that came on the tralier with no issues (ST235/80R16) L.R. G.. We live in central Tx and the local tire stores only carry Hankook, Heartland or Carlisle. I am leaning towards Carlisle as we are preparing for a long trip to the coast. Also wanted thoughts on a good tire monitoring system. All feedback is welcome. Thank you
 
Most on here recommend Sailun (sp?) tires. Seem to hold up well. I have used TST pressure monitoring system for 20 years. Back then it was most popular. Still good I think, but there are several others people use now.
Some discussions about the pressure devices not alerting to blowouts soon. I think mine will notify within 60 seconds or less but doesn't do much good with a blowout. Just monitor the pressure changing and high temps to alert you to a problem developing.
I had a leak in my truck tire once. Notified me when it hit 40, I think. I stopped and looked and it was low. Town was about 5 miles away and stopped at a gas station. By then it was 30. Found a tire store and got there in a few minutes and pressure was almost 25 I think. Nail in sidewall and they couldn't patch it, so got a new tire.
ANyway, the TST has warned me twice and I got pulled off the highway before it blew. Good luck and enjoy. OH, and this place has pretty much ALL the answers you will ever ask. With over 30,000 members, someone will have run into your problem/questions.
 
Tire brand wise if Sailun or Hercules are not available locally and you dont want to mail order them then out of the brands you listed Carlisle would be your best bet... has a decent track record... I would also UP the size to ST 235/85x16 ( more load capacity ) and tire will only make the TV 1/2 inch taller....

Tire monitor - I have been running TST 507 for the last 13 seasons... I use the screw on senders.. Zero issues with the TST... I also got the repeater for the system as it will prevent drop outs you might incur depending on the length of your fifth wheel.

Note - make certain when you get new tires have them install All Metal valve stems .. Not the rubber ones with the metal piece...

Thank you ChuckS, I have also seen some use the TST 770 which seems to have a few more bells and whistles. Looks like both should get the job done.
 
You can order Sailun tires at Walmart.

S637
ST235/80R16 14R

Maybe order via a Super Walmart with an Auto shop. Take your tires in and have them mount the new ones and Balance them.

We have EEZtire.

Chuck, in the pics it looks like the repeater is connected to DC power. Do you connect it to the batteries on the RV? TY

TST507 and Saliuns.
My TST repeater is mounted to the front compartment wall above the batteries and I clip the leads to the battery. I have to remember to unclip when we get home.
 
We have our repeater connected to the input side of the inverter so that power to it is controlled by the main battery switch. (We need the inverter on when traveling since we have a resi fridge.)
 
I am lazy and just connected to the 12V bus. The repeater is on as long as the batteries are not disconnected.
 
Another fan of Sailun tires here as well. We recently upgraded our rearview camera to the Hallowview BT7 with TPMS. Very pleased with both the camera and the TPMS aspects of the unit and I only have 1 unit attached to the dash now.

Another Sailun and TST believer here. I would purchase the TST TPMS that go inside the tire, since you are replacing the tire, tire shop can install them just like installing the valve stem. I have had good luck with TST and they sale the inside TPMS.
 
Sailuns and TST for us as well. Repeater wired to our main DC busbars up by the batteries. I did have it wired through a 5 amp breaker so I could turn it off as needed. After forgetting to turn it on several times, I removed the breaker.

Good morning, as far as the TPMS sensor what is the big selling point for using the inside tire sensor vs the external? I thought the exterior sensor would allow flexibility to remove if I sold the RV or even just change the battery. TY, Tom

I know many have used and like the Sailun, but my only experience with Sailun was not a positive one. Sailun switched to manufacturing in Viet Nam (from China), and there were quality problems. I had a tire have the tread separate, causing damage to my trailer. Being on the road I had limited options and ended up buying a new set of Goodyear G614s. Sailun soon had a recall, but because I had nothing left that could show my tire date code they wouldn’t do anything for me. The whole experience left a bad taste in my mouth. It wasn’t just the failed tire and damage, but the absolute runaround, lack of call backs, and ultimately telling me pretty much “sucks to be you - can’t do anything unless you have the original tires” treatment I received from the U.S. distributor.

I would suggest that if you do go with the Sailun tire get the place you buy them from to record the date code of each tire. Absent that, take a pic of each date code on each tire and save them just in case.

Best of luck!
 
Regarding your question about what's available at your dealership in Texas, I would choose Carlisle. I've had them before and never had an issue. A lot of good reviews out there on Carlisle's now called CalStar. I have built in monitors on my truck so I can't comment on commercial TPMs.

I added a switch to mine , but the same, need to remember to switch it off , although I’m plugged in 24/7 probably wouldn’t matter.

I have Carlisle tires on my rig now. Too new to have any first hand experience. I did a lot of research on them and all were good. Didn’t find any negatives. Carlisle web site claims all trailer tires are now made in USA(Tennessee). Mine however were made in China, the last of the tires made there. When I checked the manufacturer date, they were already 11 months old. Discount tire ordered two more sets of tires hoping for better dates. No luck. The warehouse only had the old tires. They gave me a 25% credit and heavily discounted the sales price since they were already on my trailer. I’ll just have to replace them sooner. So CHECK YOUR MANUFACTURING DATES BEFORE YOU MOUNT YOUR TIRES. I had Sailuns prior and were great. TPMS is TST. Works good. I have the outside flow through ones so I can easily adjust my tire pressure and take them off if I need to.
