Tire Advice Please

[Fordplus5er]

I have a 2010 Montana 3455SA, bought used, last summer. It has a dry weight of approximately 12010lbs, GVWR of 15560lbs. GAWR of 6750lbs. It has a mishmash of about 3 different brands of ST 80psi tires on it, all of which look to be in pretty good shape. My question is... I found some Goodyear G614's locally for $300 apiece. They are 235 85R 16. The current tires on the camper are 235 80R 16. Will the "85R" tires fit on my rims? Also, My rims are stamped "Max Load 3750lbs 110 PSI". We are pulling it to the Myrtle Beach in May and I am putting new tires of some kind on it. Are the Goodyear's a good choice? Any other tires you would recommend? Thanks in advance!

You will find a lot of people swear by the GY 614's. There are others who are using the Sailun brand tires 637's that are basicly the same rated tire as the GY but made by Sailun and they seem to be as dependable as the GY. Others on this site like LT tires and swear by them. It seems in my opinion that the really heavy trailers are the ones that need the best quaility tires. Your trailer is close to what my trailer weights are. I am going to put the Sailun 637's on my trailer. Do some searches online pertaining to trailer tire blowouts. It will give you some very good information. You can also do a search on this site about tires and find lots of people's opinions and experiences.

Good luck. This is one of those topics that stirs up the hornets.

X2 what Tom said. I just completed my research, as thorough as possible, and chose the Sailun 637. My opinion, you are living on borrowed time with your current tires. It won't take you long to find the blowout horror stories of ST tires on a rig of your size, and if it were just the tire it wouldn't be so bad. It's all the damage caused by the tire. I would recommend changing sooner rather than later, but make sure you're comfortable with your decision.

Yes, what Tom said. I have the same model as you, also bought used 3 years ago. We got through our first season with the ST tires, but discovered a bubble on the inside sidewall on one tire when we got home from our last trip that year. I had heard the warnings, but after the outlay for the camper, wanted to hold off on tires. I figured if I was careful about loading and pressures, I'd be ok, and we were, barely. That's when I decided not to roll the dice anymore and the following spring, invested in the G614's. Since then, Sailuns have emerged as a good alternative. They're not as expensive and are getting very good reviews by those that are using them. I'm not sure I'd want to go LT with the weight of our 3455's. Whatever you decide to do, do it before your trip. By the way, that's not a bad price for G614's. I paid close to $400 a tire. And yes, your rims are ok with the 85's.

I agree with all the comments above. Have you asked yourself why there is a mismatch of tires. Just guessing as one blew out they replaced with what was available.

I also agree with all the above. Sailun will be my choice when I replace my 4 year old Michelin LTs next summer.

That was kind of my thinking. Would make sense...

I'm probably going to go with the Goodyear. Someone said on "that other forum" that Goodyear would fix any trailer damage due to tire failure but I'm skeptical of that statement. That would be a nice insurance policy though.

Goodyear is good about backing up their tires and paying for damage, but with 614's that is rare. We have your rims, your age of rig and 614's with over 40,000 miles on them. As soon as the storm passes we're headed from Florida to New Mexico on those tires and then still look really good. When they get too old, I'll stay with 614's. More expensive, but they've done the job for me. We even had a suspension failure once and traveled 90 miles with the entire weight of the heavy side of the rig on just one tire and that tire is still on that wheel 3 years later.

We have had trouble-free Goodyear 614's on the last two rigs. Based on this experience, I would not consider anything else, since you cannot fix what is not broken. Your choice will be a "Made in USA" good choice!

You have some excellent advice here and can't go wrong by upgrading to any of the brands mentioned above.

The price you have been quoted for g614s is a very good price and I would tend to jump on it quick before that price disappears never to be seen again.

On my last TT's I have always used Maxxis M8008's.

Nothing but good luck with them on the lighter trailers, any experience from anyone with the larger rigs?

Me and My Buddy have been running LT 14 ply Geostar G574's for 4 years now and over 8K miles for me they are the same capacity as Goodyear G614's mine were 1000 bucks out the door from Les Schwab tire here on the West coast, Just another option for Ya that has worked for us

I run G614's . Make sure those tires are stamped on the side ( MADE IN USA ) !

I've decided on the Goodyear G614's for the camper.

Also putting 6 new Coopers on the truck tomorrow.

Man that's a lot of tires in a week. Hopefully I'm done for a while!!

[pkbridges77]

Great choice. Wishing you miles of trouble-free adventure.

You won't be sorry with the G614's as I've learned over the last few months.

Please consider a TPMS system to monitor the pressures and Temp. Read the threads about them, they can save you a lot of trouble, cost, & headaches if a tire does blow and you don't realize it.
Safe travels.

I posted a question to the wrong area, so here is my question again to you more experienced tire issue people!
We are looking to replace tires. Looking at the ST235/80R16 G Saluin S637T
Is this a trailer tire? Are we to be replacing a trailer tire with a trailer tire or truck tire?
Our current tire is E rated... these are G but it is still a trailer tire. Sorry to ask a dumb question, but read the posts and need clarification before we buy.

ST means trailer tire. Here's a definition:

"ST tire designation: ST stands for Special Trailer tire. ST tires are designed for use on trailer axle positions only. They are not designed for the load or traction requirements of a drive or steering axle. ST tires have strengthened sidewalls to prevent the tire from rolling under the rim in turns and when cornering. All ST tires have a maximum speed rating of 65 mph. ST tires feature materials and construction designed to meet the higher load requirements and demands trailer towing presents."

My one piece of advice would be do not, under any conditions (even if they GIVE you the tires) buy or use STs made in China.

[Carriage House with View]

thank you for your replies! So, the long of the short is that we DO get trailer tires with high rating, and not from China.
We do have the tire monitors, and will be using them on the new tires. After we used them on our older trailer, we were told that they allow air leakage and we put them away until we read all the discussion.
While I have your attention, how do I get the post to go to the main area and how do we post a picture of our rig... it's fun to see everyone's rig. Thanks.
