Howard,
We have ST235/80/R16's. One came apart today. With your knowledge sir, would you give us a recommendation of replacement. One china bomb is enough, not saying other want do the same but we sure would appreciate any advice Howard. We had her weighted and she was 15,700. Axles are 7000 if that helps.

You didn't ask me but this is one of my hot buttons for safety - Having used both of the above tires get the G114's on 17.5" wheels and be done with blowouts. Direct replacement on 8 bolt hubs. Same overall size. (BTW, that's what Howard has - he replaced the G614's on their rig years ago.) The G114's at the recommended air pressure are just fine even for the relatively lighter weight trailer. Now with way over 100,000 miles on G114's (after replacing the G614's on the previous trailer) we've had nothing but good results and we "do have stories." They will last 50,000+ miles and while any tire can blow out these "don't." I have 45,079 logged miles on current tires and they are still at 11/32".
Call 'em and they will ship you four, on 17.5" wheels, balance and ready to mount. (419) 272-2277 They are very good people do business with as many of us can attest.
This recommended setup is expensive - and darn well worth it for safety and longevity.
My opinion.

Thanks Bill,
We have wanted to upgrade to the IS Suspension in the future so I guess this is the first step. Thanks again.

This is why we always recommend taking the tire upgrade option if the manufacturer offers it. :)
The Goodyear G614s (LT235/85R16) would be the minimum upgrade I would recommend without having to change rims. (You would need to verify that they are close to the same diameter as your current tires, just to be sure there is no fender rubbing, etc.) They have max load of 3750 lbs at 110 psi (load range G) and will do quite well UNTIL you start getting close to their weight capacities. If your weight per tire gets up in the 3500 lb and above range, those tires have a higher failure rate. You would likely be fine at your weight if I remember correctly.
But for additional peace of mind and safety margin, Bill's suggestion is indeed what we have - Goodyear G114 commercial tires (215/75R17.5). They require 17.5-inch rims, but the overall diameter is very, very close to the same diameter of the G614s. But they have a max load of 4,805 lbs at 125 psi (load range H) and are very high quality tires. There are other alternatives out there and cheaper alternatives, but we can personally vouch for the G114s and the extra expense is justifiable for full-timers in my opinion.
We also got our tires and wheels from TrailerTiresAndWheels.com. They will mount the tires on the rims for you, balance them, and ship.

You are getting advice from two of the most knowledgeable 5th wheel tire guys ... Howard and Bill know of what they speak. Therefore my input will sound like an echo, but for what it's worth.
If money isn't a problem, go with the Goodyear G114 H rated tires (they will require a high spec wheel due to the pressures and will be 17.5" which is bigger than your current 16" rims). If you choose to stick with your current wheels and decide to go the Goodyear G614 G rated tires ... make sure your rims will allow the 110 psi max pressure of the tire rating.
I am on my way to MorRyde (for a May 02 appointment) to get the IS and disc brakes and G114 wheel & tire upgrade. I currently have 4 Goodyear G614's that will have about 10,000 miles on them. Your choice of tire should be driven by your weights on each wheel. My GVW is 16,400. My heavy wheel is my left rear which weighs 3,440 lbs. (primarily due to the 500 lbs of fresh water that I carry and that the tank is on the left side of my rig just behind the rear axle). The G614's are rated at 3,750 @110 psi. So I'm getting too close (for me). I'm sure that a blow out is a miserable experience and I hope to avoid that. Good luck to you guys.

Thanks Guys. Well after many phone calls to Vilano its looks like there would be a lot more than we can do at this time to upgrade the rims. If we are going to upgrade them we would also do the IS Suspension and brake. So looks like its G614's am tomorrow. I appreciate all the help gentlemen.
Happy Trails

Rush,
Not a bad choice as long as your 4 wheels individual weights are 3,200 - 3,300 max (Lower is better). Remember to ensure your wheels are rated for 110 psi. It's what I have on my rig now and we've been trouble free for 10,000 miles. My tires still look new and are wearing well.

Ron: We may have already had this discussion but I'll re-post for those reading along. IMO there is no need when upgrading to commercial grade G114 tires from G614's to purchase a G114 spare. If you have a serviceable G614 on a rim now as a spare just use it. You can physically (check it out) intermix the G114 and G614 on the same side without issues short term as they are, as Howard said, almost exactly the same effective radial size. ("Ask me how I know this." - No, the G114 didn't fail - the Nev-R-Lub bearing failed. Another story.) IMO doing this saves quite a bit of money with very little compromise to safety.
Side note - when you are at MOR/ryde in June, after getting up at "O-Dark-Thirty" to move into the service bay, run down to Granma's House of Pancakes, 3709 S Main St, Elkhart, IN. 41.640924 -85.927020 will take you to the driveway. It's south of US-20 about 10 minutes from MOR/ryde. If you like a traditional breakfast I think you will enjoy it.

Bill,
Brain cramp. I'm getting the work done at MorRyde in MAY (not June), which is why I'm on the way. I was going to use the G614 spare as is, so thanks for that money saving tip. My plan is to arrive at MorRyde at 1 PM on Monday the 1st for the weighing and measurements, and put the rig in the bay that afternoon to avoid the Zero Dark Thirty wake up . We're going to stay in a hotel based on the noise levels and trains we've heard about. I will try Grandma's.

update ... I had an unfortunate event that caused a strained thigh muscle which cramps badly when I try to sit down, so I can't drive☹️ Had to reschedule my entire next two months, so morRyde is now Aug 8-9. Bummer!

The vehicle manufacturer is not allowed to use ST235/80R16E tires on 7000# axles because many tires in that size and load range are only rated for 3420# maximum load capacity, it's not legal for the vehicle manufacturer to use them as OEM on 7000# axles. To avoid a safety violation the vehicle manufacturer can do one of two things. Inform NHTSA they have installed those tires from a manufacturer that has certified their load capacity at 3500# or over. Or the trailer manufacturer can set the GAWRs to a value below 7000# to accommodate the 3420#tires. You should confirm your GAWRs capacities with what is listed on the trailer's certification label.
The standard OEM wheel/rim for that ST235/80R16E tire is 3580# @ 80 PSI. If the trailer manufacturer had approved an optional tire with a load capacity of 3750# @ 110 PSI the OEM rims/wheels may be rated at 3960# @ 110 PSI. However, the standard LT235/85R16G (RST) tire rated at 3750# @ 110 PSI is a steel cased tire and has a single approved rim width of 6.5". That 3960# tire may have a 6.0" - 7.5" approved rim width. Not coincidentally, the ST235/85R16F has a load capacity of 3960# @ 95 PSI.
