Replacement Tires?

Need to replace 4 tires and this morning a local dealer recommended I go with the TOWMAX STR E Rating 10 Ply(ST235/80R16) Would appreciate any info/feedback on these tires. Would have preferred the MAXXIS but apparently no dealer in my area carries them anymore. drat!

ABSOLUTELY DON'T go with ST tires!! Go with any number of LT tires. Goodyear, Bridgestone, Michelin,and BF Goodrich are a few. This dealer is definately steering youvinto some bad tires.

I have been looking at tires to replace my ST tires. The problem that I see with the LT tires is the load range on the tires. The ST 235/80/16 load range E are rated at 3400 LBS
at 80 PSI. And the LT 235/85/16 load range E is rated at 3025 LBS at 80 PSI. That is a 400
LBS loss per tire. That's 1,600 LBS. I also look at the Towmax RST tires. They sound like
a good tire but have not talk to the guys at Discount Tire yet. From what I understand is
there are no ST tires made in the US. Maybe Carlisle, but I herd bad things about them. I
still do not know what to do. The Goodyear G614's are very expensive.

Bruce,

If your 3150RL is anything like mine, fully loaded my axle weight is 10,700# hitched to the truck. My pin weight is 2300#.

So, you only count the axle weight for the tires, 10,700# divided by 4 = 2675# per tire. So you are actually 350# under the max weight of the LT tires.

I'm going with the BG Goodrich when it time to replace my Marathons.

Bottom line, YOU need to packup and head for the scales.

X2. Also, one thing to remember, your tires. carry that rig you spent all that money on. Based on that, I see 614's as cheap protection.

And the LTs are rated better than the STs. The STs are rated at the very top of there load range and the LTs are rated with alot of safety to spare. My 3650RK is 2850 per tire and never had a problem since going to the LTs other than my axels ruining the last set with around 28k miles on them. I now have a new set of uniroyal laredo HT/Hs and very happy with them and a little over 700.00 mounted and balanced. every body should spend their money like they want to so I will buy diesel with the extra.

Had a 2000 HR that came with Goodyear HT on it. Replaced them with the BF Goodrich TA's but traded the trailer in a year later for the Montana 3150RL. When I seen that it had
the Goodyear Marathons on it. I did not know the problems the ST tires had. Didn't join
the Forums until we bought the Montana. Towed trailers for about 25 years and last year
was the first that I herd of this tire problem. I never had a tire problem with my TT and my
last 5th wheel. So you see why I just don't want to run out and buy new tires.

Even losing 400 lbs you are still way ahead with LT tires. If your trailer has ST E rated tires on it LT's will definitly hold up better then them. Now if you are that heavy then G rated tires are for you, but then your trailer woulda had G's on it already.

I had never had any problems with trailer tires either with 12 years of pulling a previous fifth wheel. The Marathons will not handle the bigger rigs. Their belts simply will not hold up. A 3150 should do fine with a quality E rated truck tire. Personally, I put on the G614 when my Marathons failed to add as much safety margin as possible. I was like you, read the warnings, didn't want to change out new tires, and thought if I took great caution and care I would be OK. Luckily, I saw the tread bulging in my driveway, and avoided the dreaded blowout from the "China Bombs". Don't wait man.

Bridgestone Duraviss R250, great tire choice for your rig.

In the "good old days" mentioned previously, our tires were of American production- Under "nafta" and other such trade agreements, foreign products that are not subject to our standards are imported and palmed off on us- Unless, of course, we actually examine what we buy- I buy American if at all possible- JMHO- Don

On the contrary I think in most cases the belts are great on ST tires! The only problems I've had is that the separation of the belts from the sidewall or the sidewall blowing out are the problems. These can be exacerbated by poor tire care, underinflation and tire abuse. I've even seen LT tires with side blowouts come from neglect. But there is enough suspicion that ST tire manufacturers don't meet their own specifications very well, ala the terrible reputation that Chinese tire makers are producing less than stellar tires.

Hopefully the caretaker of the "ST versus LT" study will come along. This describes very well why LTs may do better than STs and if you want to stick with an ST, Maxxis is the one to try.

There are a lot of people that don't take care of the vehicles and the tires. The phrase, "hey, I just put gas in it and expect it to go", is heard too many times. I think trailer owners are much better at this and for that reason and with the increased weights, we tend to check a lot more. So when something goes boom anyway, it's quite frustrating. Unfortunately I've met way too many RVers who don't do the proper checks with their tires either. Until the public becomes more caring, the manufacturers will not try harder. Just my opinion.

I have Marathons and try and treat them with kid gloves. Next set of tires will probably be Maxxis (American made and great stats) but no matter what I do, the gloves are not coming off. I think the G614s are too big for my old trailer.

FYI - LonnieB is a tire manager and owns a Monty so his recommendation should be strongly considered. Also, don't forget to be able to check the DOT code and get the manufacture date so you get new tires, not ones sitting in their stock room for a few years.

I have the same 5th wheel as you and replaced the mission tires with BFGoodrich Commercial TA'S. I think if you look at other sites along with here you will agree that the number of people the are running them without problems will help in your decision.LT 235/85R16

When on the road with our TT a few years ago I was shocked to note that all four of the trailer tires were almost bald on the inner/outer edges with full tread in the middle. As you no doubt have guessed, I did not watch the tire pressure very well and was running the tires badly under inflated. Well, out in the wilds of Texas the only replacement tires we could find were TOMAX...ran them the rest of the time we owned the TT with no problems. However, they were relatively cheap tires and the old saying you get what you pay for comes to mind. Given the weights of our Montanas, I would not recommend a cheap tire...as far as putting a truck tire on a trailer, I just do not know what to think! I do know that when the time comes to replace the tires on our Montana, we will go with a trailer tire...right or wrong.

Someone mentioned Carlisle tires might be made in the USA. I looked at a tire made by them called Radial Trail. P23585R16 load range F good for 3960 lbs each. Called customer service and asked them where they are made. Response: at our tire facility in China. Said "no thanks" and hung up.
