Well it happened

Had a blow out on right front tire. Travelling 55 mph tire psi around 85 and temp indicated 95 degrees. 3 year old tire 8/32 of thread depth no indication of any kind of problem at all. Tire minder did quickly alert and showed 0psi. I guess I did get lucky and suffered no damage other then to tire.

What brand tire do you have? We have factory installed Trailer Kings on our 2015 5er. Trying to decide if I should keep them for our trip to Denali NP next year or replace them before the trip.

Glad you didn't have any damage. What brand of tire pressure monitor do you have?

Exactly why I spent several hundred bucks on my Tireminder system. It just paid for itself..My parents had a blow out last year near Richmond with no monitoring system. Had Good Sams roadside change it out and ten miles later, the other side blew out....$7500 worth of damage...the system pays for itself!!!

I'm still running the original tires that came on the unit tow max power kings . S/t. 236/80 r16. I have been checking around but nothing out there seem better then the other.

On the 2012 Cougar RES 327, I would go with good LT truck tires, as they will be way under loaded for that rig. For the 2015 3402 Montana, go with either the S637 Sailuns or the Goodyear G614, or there are a few other G range tires available that will work. On both rigs, get rid of the E range ST tires, and you will have a much safer rig, and will likely never have a tire failure that will do major damage. We went through 5 of the Marathons, never had a blowout, caught them all before total failure, then decided to get the Goodyear G614. Get to see much more scenery, because I'm not constantly watching the mirrors for tire debris flying from the rig.

Pull off the right rear tire before it blows. Remember it was over loaded holding up the right side weight all by itself. I came across more than a few rvers who had a tire blown or flat and said they just had the other one on that side go a short time before. If it was me, I would be replacing all of them at this point just to be sure due to age. Seen it on the loaded 18 wheelers also.

Last December I bought a new 5er with TK 235/80/R16 LR E tires. After research I believe they are probably the best of the bad. With just 4500 miles on them I had them replaced with Carlisle of the same size. I have only heard of two failures with those although sure there are more.

You make a valid point about replacing the other one, but since i have only two of the original tires left i should just replace them as well.

If you are close to your maximum loading on the tires, a possible replacement tires you might want to consider are the Carlisle Radial Trail HD in 235/85R16 LRF. They are 12 ply rated, 3960 pound load rating at 95PSI.

Your trailer wheels are probably not rated to carry the Sailun 110 PSI, but likely are rated to carry the 95 PSI Carlisle 12 ply tires. I've no idea on pricing, and possibly the 85 series tires may have a clearance problem in your wheel wells (they are 0.9" taller than the 80 series tires). But they would give you an added 440 pounds per tire which is 1760 pounds on the 4 tires. Quite a payload capacity increase, all of which would be "added reserve capacity" on your tires.

As soon as I saw the picture I immediately recognized the Power Kings, you can do much better with a Maxxis or Carlisle tire.

The wheels are a Sendel T03 which is rated for 94 psi. I have the same on my 5er (8 bolt vs 6, but both 16" are rated the same). I initially replaced my PKs with Carlisle Trail RH LRF tires, rated at 3960 @ 95 psi. The wheels held up fine at that air pressure. I liked them, but lost one to a nail. When I went to replace it, Discount Tire ordered in the LRE instead of F. I had ordered 2 so I could replace the spare as well and already pulled the wheels off the RV. They had the Hartland ST Radial LRG rated for 4079 @ 95 PSI. It's the only LRG tire I'm aware of rated for 95 psi instead of 110. They made me a great offer to take all of the Carlisles off my hands and replaced all 5 with the Hartland. I haven't put them on the road yet so the jury is still out, but they are a heavy tire that look very good on the 5er with little sidewall flex. Basically, the OP has some options and just about anything is an upgrade from the Power Kings.

The Sendel T03 I'm looking at is rated at 3580# with a pressure rating of 94 PSI. Basically that rim is OEM provided for tires sized ST235/80R16E rated at 3520# at 80 PSI. Not quit enough load capacity for the larger tire.

I'm pretty sure that's a typo for the PSI rating on a LRG tire. Someone needs to check a TRA load inflation chart and inform the distributor of their error. (The TRA approves load inflation standards).

The new Sailun S637 G range tires are rated higher than the older G range tires. They are both called ST tires and are 75 mph rated as well. The ST235/85R16 is rated 4400 lbs capacity single, and the ST235/80R16 is rated 4080 lbs capacity single, both at 110 psi. http://www.gosailun.com/MRT/Tire/S637T

CW, I understand what you're saying about the load capacity of the wheel not being high enough for a heavier tire. In most trailer situations I would agree that the wheel should be rated the same as the tire to prevent someone from looking at the load capacity of the tire and inadvertently overloading the wheel. In the case with our RVs, I don't see this as an issue. Most people will never overload the RV and the wheels are sufficient for the max payload of the RV(barely). When we put a higher LR tire on the wheels, yes the tire is now rated for weights that exceed the wheel capacity, but it's only to give extra room and not work the tire as hard vs maxing it out. Hopefully this leads to less likelihood of a blowout. Personally, I'm getting ready to change the wheels on mine as well.

As for the PSI rating of the Hartland LRG, I was surprised as well, but that's even what DT has in their computer for the max PSI. It was a first for me and I had to look at the tire to believe it.

Both of those tires require special high load capacity rims size 16”x6.5” rated for their load capacity and 110 PSI.

Here is a picture of one depicting the required rim width.

John what's the sped rating on this tire?
Good price, online shipping will kill you. but the pricing is right.

Cbrez, I almost came out of my chair when I read your post about maybe riding on your Trailer Kings to Denali......I am not exaggerating when I say I would be worried about towing it as far as the dealer to have a new set of real tires installed. Your trailer tires were on borrowed time when it was towed out of the factory. This forum and many, many others are full of horror stories about these POS. We went with Sailuns after Geico parted with about 9K for our repair (Yes, both did blow within 100 miles). I only push Sailuns because it is a great tire at a somewhat reasonable price. Read up here and you will find about four other good, dependable brands.

Ditto. Probably the worst tow highway possible with China bombs. (shudder)
