Hi, I have read through other tire threads on this forum and I would like additional input from this informed group before I fork $$$.
I have a 2008 Blue Ribbon 3H 7ft SWLQ trailer with 235 85 R16 Carlisle tires. I had a blowout last summer on the interstate. Not a fun experience on a scorching hot Sunday!
I am considering going with Good year G614 RST. They are pricy, $330 each including mounting/labor/disp fee/new valve stems.
I also saw positive comments about the Michelin XPS-Rib.
What are you all using on your trailers? The Carlisles are dry rotting and I keep them covered and off the ground when parked.
I do not haul thousands of miles per year. I do plan to keep my trailer for a while and want to buy something that is reliable and durable.

If it were my trailer, and I currently had Load Range "E" tires in a LT , I'd go with the Michelin you suggested. If I had LR "G" tires (you probably don't), then I'd use the Goodyears. Now- your Carlisle may be ST which are rated different (you didn't specify). Then you need to check on wheel capacity and match it. But in all liklihood you have tires rated around 80 PSI and 3042#, in which case use the Michelin. They are great tires. Just my opinion.

The Goodyear G614 will also probably require new rims that are rated for 110psi. The load E rims are only rated to 80psi. So besides the cost of the tires, You may have to buy rims also if you go to a higher rating.
Have you weighed your trailer? just how close are you to the max limits of the E range tires?
Strictly guessing here. I'd bet your trailer is around 13,000 to 14,000lbs loaded and ready to go. With a guess of 25% on the pin and 75% on the trailer tires that would put you at around 2600lbs per tire which is with in the limits of an "E" range tire.
Going to a "G" tire would give you a greater margin of error. But most installers will not install a tire that is marked on the sidewall for 110psi on a rim rated for 80psi.
I'd probably stay with the "E" rated tire and buy a quality tire.

Thanks for the additional info. The current tires on the trailer have a rating of 3960lb. The sidewall says 95 PSI. So I will go with the Michelins. I found a dealer here that has them for a little less than the Goodyear G614.

I had those same *%#@ Carlisle tires on my trailer...when the first one blew, I contacted Carlisle and because they were less than 2 years old, I was paid market value for ALL 5 tires. (I sent all the tires back to Carlisle.) Of course, I had to have a "discussion" with the folks at Carlisle but in the end, they paid me and I was satisfied. I replaced with the Goodyear G614s. My rims were rated high enough to handle the Goodyears.

this is good as an all terrain tires. For you guys what would we going to consider in selecting a perfect tires for a particular trailer. Is the recommended PSI for the make of tire is the sticker stamped on the sidewall of the it?

The current Carlisle tires are load range F 95PSI. The empty weight of my trailer is 6600lbs, so with two horses, equipment, loaded it could get closer to 10000. How do you determine if you need a load range E, F or G? The axles are rated for 7000lbs. Would the MichelinXPS Rib with 80 PSI and load E work for me? or would I be better to go with the Goodyear G614 110 PSI Load range G? They are in about the same price range where I live (around $300 each) Thanks very much. I learn a lot from you all on this forum

I run G614's on my 8000# axle trailers and Michelin XPS ribs on the 5500# thru 7000# axle trailers.... That Michelin will run for more miles that the G614, seen them on pickup trucks with 100K+ overloaded miles. Both tires have steel casings but the Michelin seem to have a deeper, harder tread compound and will support alot more weight than for what it's rated.... Can't go wrong with either on your trailer, pick your poison!!!

The goodyears are regrooveable. They have a shallower tread on purpose. Someone with more tire expertise will have to explain why you would want that and what the benefits are of regrooving a tire. But I think it has to do with less tread squirm and lower running temperatures. So when they get bald, Don't throw them away, Go regroove them and start their second life. I suspect most of us will have tread left at 5 years when it's time to just replace the tires because of age.
Ideally you want the rating on the tires to equal the rating on the axles. Hence a 7000lb axle would need two tires rated at 3500 lbs each. The Michelin 235/85r16E are rated at 3042lbs per tire, So they are optimal for a 6084lb axle. It all boils down to what you want your weak link to be. The tires, the axle, the bearings, the springs they each have a rating.
The Goodyear 235/85r16G is rated for 3750lb per tire which makes it optimal for 7500lb axle. But the Goodyears ( or any other "G rated" tire) need a rim and valve stems rated for the 110 psi. And most rims are rated for 80 psi not the higher rating.

I would suspect that since the Carlisle tires on the trailer were 95 psi that the rims would be rated higher than 80psi but I am just assuming and ya'll know what happens when one assumes. HA!

I went to a Tire dealer that sells both light truck tires and commercial tires that the RV store/service refers their customers. I decided on the Goodyear G614 and asked the service manager to verfiy that my rims will support the psi. He checked and mine are. So I have 3500# G rated tires on my 7000# axles. I learned from you all:) I also bargained a bit and got them installed (with new high pressure valve stems) for less than the original quote.I may have also been fine with the Michelins too. I tested them out yesterday and hauled on the interstate. Trailer pulled great!Thanks to everyone for their sound advice.
