Tires for a Fifth wheel
I have a Keystone Montana 3791 41 footer, I am looking for a set of tires for it. I have the original tires (Trailer king st235 80 R16) about 2years old and 20000 miles on them. I am looking for a new set so if anyone can comment on whats the best set let me know.

I put Goodyear Endurance on my 2014 Laredo 346RD. The Trailer King ST235/80R16 that came on my unit started separating at 10,000 miles on the tires. I continually monitor and checked pressure. Even used a Tire Minder monitoring system. I'd recommend the Endurance because they are made in the USA. Plus when I'm towing my FW I can really feel the difference.

Endurance, Carlisle's, Maxxis, Sailun in no order are the top recommendations on the forum. Endurance is still rather new so the jury is still out on longevity.

With the size and weight of your fifth wheel I’d run nothing less than G rated 14 ply tires...
TK tires in my opinion are one of the worst on the road..
I’d recommend Sailun S637 235/85 x 16 as an affordable upgrade that in my opinion is as good or better than GY G614 tires...
I currently run a Les Schwab Geo Star 14 ply G rated tire on my 12K fifth wheel.. four seasons of use and I’m not even thinking of new tires yet..
Proper air pressure ...common sense towing speed.. and covered when not rolling will get you best life out of tire

If you go to the "Tires,Tires,Tires" forum on this site you can read posts on tires until you need glasses or go blind. If you want to save time, Chip's advice is spot on but you will hear many opinions on changing over from ST to LT tires.

I replaced the Trailer King tires a couple of years ago with the Sailun ST235/80R16 and have been very pleased with them. I will buy them again when the time comes.

I picked up a set of 4 Carlisles at Sam's Club. $96 each. $15 per tire for mount, balance, flat repair, etc. With tax around $500.

I would also suggest the Sailuns, I'm super happy with mine, they are a seriously beefy tire. Also, if you want to stay with the OEM size, they are available in 235/80R16 (that's what I have).

Be careful. The Trailer King ST235/80R16 LREs are rated at 3520#. The GY Endurance, same size and load range are rated at 3420# and do not qualify for fitment on 7000# certified axles. There are a lot of new brands out there and half of them are building the ST235/80R16 with a load range "F". The LRF will provide much more than the recommended 10% load capacity above axle rating. And, it's the same designated size and uses the same load inflation chart as the LRE.

If you want to stay with a tire with the same diameter and your wheels are rated to 110 lbs inflation, then the Sailun ST235/80R16G would be a great choice for a replacement tire. If you have clearance for a slightly larger diameter then the Sailun ST235/85R16G are also a good choice. Both of these are steel ply carcass offerings(AKA All Steel Ply tires). Chris

Suggest you look at the Montana Owners Forum
You’ll find lots of good information there about these heavy trailers.

Where are you getting your Sailuns at? I don’t see any retailers or tire chains that carry them around me.

Yes they are maid in China but you will likely find all tires large enough for your unit are made there. These are not China bombs. I love them and the cost is really reasonable.

Topglock, I believe Meekhof Tire Sales and Service in your area may be your answer.

Sorry to hear you had problems. I assume the St235/80R16 were LR-E. Did you always run 80 psi cold? What was your actual scale weight? What is the published GAWR?
