You should really look for a tire with a closed shoulder and a rib design. IMO they work best in trailer service.

What size tire and axles does that unit have?

Not sure I read this correct - you took the 16' wheels of the fusion and installed 17.5s?

I have the same fusion, and caught one of the carlisles right before explosion. It was 1.5" larger in diameter than the other 5.....(6 with the spare). Rounded out to point I saw it from the edge of the parking lot as I was walking up to it.

Looking for options, but I need load range E or greater. Looking at Goodyear or Kenda

I'm not so sure that tire size has a lot to do with safety and tire longevity. Availability is a different subject. I think a lot of people get into trouble by trying to turn it into rocket science. I've read many posts by people that have poured over the rating data and have determined that you should run tire pressure based on the load being put on them. I disagree with that and so does every tire expert that I have talked to. The advice that I get, and what I stick with is to run the tires at max pressure. Max pressure means less friction and less heat generated which is a tire killer. Speed is another contributing factor to tire failure. If a tire is rated at 65 MPH, that's what it means.
LT tires are a better choice, but I think a lot of people get in trouble thinking that it's the best tire without looking at the rating of the tire. The rating has to be at least as much as the ST tire you are replacing.
It's all about pressure and speed, IMO.

Just to back up your observation about speed, today going out on I5 between Portland and Salem, wife and I and another couple are headed to the Outlet stores, we are doing 65MPH in our Tundra in the slow lane, no trailer just us in the truck. Going by us in the fast lane were two three-axel toy haulers 5th wheels being towed by late model Diesel pickups. The pickups had more 4 wheel riding toys in their beds. One of the trailers had a white wheel instead of the mags that were on the other axils, suspect it to be a spare. High speed, heavy load and we wonder why tires blow!

Angry Tires

We also have had 3 steel belt separations and 1 blowout with my Power King Towmax STR. ST 235/80 R16 for my 5th wheel Cougar 323 MKS March of 2012. They are CR_P. After about 10K miles and I am very conscientious watching the tire pressures.

I was very lucky 2 separations I saw before they blew and the blow out was the spare (go figure). These things are dangerous. 3 out of 5 have failed and I am not giving the 2 remaining another chance. Power King was very helpful on the 1st prorate and sent me a check. I expect no problem with the other 2 failures (prorated) but I don't want the 2 remaining either we will see how that goes.

I like the (pricy) Goodyear G614RTS 14 ply. They are rated at 3750 and the rims that came with my rig are rated at 3500 but my plan is not to overload my 5ther anyway.

Any better suggestions out there?
Thanks

We got Toyo LTs. Easy to find replacements if necessary while traveling.

This reference is from the Toyo truck tire data book.

Just useful information.

The approved rim width range for that tire is 6.5" - 8.0". The measuring rim width is 7.0".

Tires

I had issues with tires in the past. Till I found this tire. It's called pro meter. Have never looked back since. I even switched my small utility and tandem boat trailer to them. I put over 7000 miles on my last camper with them and still were rolling when I sold it. About to buy a set for my new fuzion it has some off brand i never heard of. Just to make sure. You can find them at area wholesale tire company. They are all over the south.

Two tire losses. Neither "blewout," but caught one separation on morning "preflight" inspection and changed tire. Three days later we had a total separation on the other side (rear tire). This one really ripped up the underside of the right side. All this near Midland, TX. Bought 4 new Carlisle tires from Discount. $5K in damage.

327RES w/13K on Powerking Towmax, Good tread. PSI = 80 prior to each morning departure.

Prometer brand. It's all I run on all my trailers 5er,boat,utility. And never have had a failure. But all tires have shelf life. The rule of thumb is 5 years. But if they are exposed to the sun that shortens a lot. I put over 7000 miles on my last 5er and never lost one. Good luck

Our Big Sky weighs in at just over 13k. So the safety margin is good.
Maxxis are good tires. Put them on our first TT. Upgraded from 14" to 15".

Good luck!
I did the same the same thing after a blowout. I went to 17" wheel and Goodyear G114's. Pricey, but well worth the safety margin. My 5er is more stable when parked as well. The trailer manufacturers know about the OEM junk tires and continue to put our safety at risk.

I am not a fan of Towmax tires but I will say I put approximately 10,000 miles on mine without any trouble at all. I did run a little faster than I should be but I guess Im one of the lucky ones. They still looked good when I changed them out. I now have the Maxxis 8008 on mine but only have 200 miles on them. Maintain your air pressure, keep the speed down and pray to the tire gods they dont blow.

I'm just wondering if Towmax gets a bad rap because they are OE tires and pretty much max loaded right from the start. Seems like most people complain that they blow out, then say they upgraded to a different brand and higher load rated tire. I don't have any experience with Towmax yet (they are on my new Alpine). I will probably change them to a different brand F load range tire in the near future since I'm not pleased that Keystone put an E rated tire on my RV to begin with, but I still wonder if a properly loaded Towmax would perform better than they get credited for.

Don't wait too long my fine friend! I had the notion that I would do the 80/60rule... 80 pounds and 60 mile per hour, and followed it religiously! At around 6,000 miles BOOM, looked in my mirror to see trailer parts and tire shreds being strewn all over the highway! After a three week wait for the parts and repair it was not worth trying to get some use out of the Towmax that came on my new Alpine 3450RL!

My replacment:

17.5 inch wheels

235/75R-17.5/16 M-1430 HIGHWAY H rated 125lb
TUBLESS METAL STEMS

Don't plan on waiting long, but have to take one trip before I can get to them Only 75 miles and I have TPMS so I can keep a close eye on them.

Unfortunately you are quit right about your tires needing to be replaced with some having more load capacity reserves than the TowMax rated at 3520#. I suspect your certification label shows your axles with a GAWR of 6750# or 6850#. Not much load capacity reserves at either GAWR.

If you do have the 6750# GAWR Keystone has made an error. Unless they have provided a certified letter to NHTSA insuring them they are only using 3500# or 3500# ST tires on those axles. They must also inform the owner in writing that those tires must be used or something higher than the 3520# tires. The explanation for that is another DOT regulation that says - in part - that any tires of the same size and with the same load range (LRE) having more than one established load capacity must be defaulted to the lowest load capacity unless otherwise stipulated. ST tires sized ST235/80R16E have three distinct load capacities, 3420#, 3500# and 3520#. The 3420# tires do not meet the minimum requirement for fitment on 6750# GAWR axles. Maxxis tires are very popular replacements and their load capacity is 3420#.

Don’t take this post as being negative about the TowMax tires. I’ve been using them very successfully on my 6000# axles since 2005 (currently on the 3rd set).
