New tires

Load range C can handle up to about 1980 lb each, so 7920 on 2 axles. Since the axles carry a max of 90% of the trailer GVWR, that would allow up to an 8800 lb trailer. That's a not uncommon GVWR for a 30 footer, and low-balling the tires is an all-too-common shortcoming in entry level models. Anything to knock a few $ off the advertised price.

They may be rated for that, but you also have to consider the sidewall strength.
Load range C tires will squat with that much weight and you can only inflate them to about 45lbs. Load range D 65lbs. Load range E 80lbs.
What damage is occurring to the belts and tread when the tires bulge?
Plus the tires will run hotter.
 
I've been running on Hercules for years now on my fifth wheel. However, this last July 4, I did have a blow-out, but replaced it with another Hercules. Two of them are at least 5 years old, the one that blew was 2 years old, and the other is about 3 years old.

I examined the other 3 very carefully and with the help of my RV tech guy, he pointed out my Hercules were dry rotting on the side walls and pointed it out. Although there may still be life left in these tires, I decided to go ahead and get the other 3 replaced.

Went to my local tire shop and talked to them and found out they can't get Hercules right now. So, decided to go with Carlisle's. However, my tow vehicle is in the shop so can't get the trailer to the tire shop. But, it's in the works.


I had Carlisle's on my two previous travel trailers and they were good tires, never had a hint of problem with them. So, I'm hoping their "G" rated 14 Ply will be just as dependable as they use to be. So, decided to put the Hercules on the spare and get the 4 Carlisle's on the ground. .... whenever I get my truck out of the shop!

Why?? "C" tires are rated at 50 psi and can be run continuously at that psi. And must be if they are to carry their max load or anywhere near it. The tire engineers have that figured into the ratings.

Don't get me wrong - I'd purchase LR D instead if my trailer was real close to the C-rated max limit, but run the numbers before condemning the C-rated tires.

There are uses for C tires. Cargo or flat bed trailers within the load range.
A travel trailer with a high center of transfer a lot of weight to the outside tires while making turns, even long sweeping turns
Plus the side walls are weaker causing the tires to roll under.
 
First of all, I find it hard to believe a 30 foot toy hauler came with load range C tires.
Those are used on utility trailers.
Check the label on the trailer and see what size and load range it shows.
My 28 ft toy hauler came with load range E.
I replaced the original (Chinese) ones with the Endurance after the first year.
I have probably 10,000 mile on them and they still look good.
Not trying to be smart but that is what they came with.

I even spoke with Coachmen about the tire and rim size but they told me that was correct for the trailer at the time of mfg. The trailer has a gvwr of 7900 lbs. with a tongue weight of 957 lbs. And before you tell me that is an incorrect weight, I have weighed the rig multiple times with my Shurline 2000 lb, tongue weight scale.

Strange, my KZ 270thle came with load range E 215-75-15's
About the same specs as you Coachmen.
900lb tongue and 8200gvwr.
When I had my FR 22rr, it had load range C on it.
Of course that may the difference between a Forest River and a KZ.
BTW, I had 8 different problems with the FR in 2 years.
The KZ is 8 years old and only one problem and it was an awning recall.
 
Since you got good service from the Goodyear's, why not stick with them?
They do cost more, but are rated as one of the top tires.

If you had read my post, I stated that I will not pay $200 for a tire that may have 10,000 miles on it(probably less) at the end of it life. This is especially true when there are tires on the market that are probably just as good if not better than the Endurance. Not to mention less expensive.

I for one don't blame you. I don't think that the less expensive ones are as good as the Endurance but the price of those is ridiculous. You can get a very good quality tire for half the price and if it is not being used that much there is no need for the GY. If a nail goes through the GY tires and get run on flat they will come apart just like the other ones and road hazards cause most tire failures.

Hankook makes that size (ST205/7515) in LRD for half what the Endurance costs. Carlisle too, for even less than the Hankook. Both reliable tires with solid reputations.


Both of those brands are on my short list along with Maxxis. Unfortunetly the Hankook linc took me to a load range SL while I have not heard of the Carlisle tire that you linked. I am looking into the Carlisle Radial trail HD in a load range D

I am pretty sure the Carlise Reliance is made strictly for Walmart and I have to wonder if they make them the same quality as their Trail Radial tires that are made for other vendors.

I bought one of those Harbor freight 4' square trailer frames to build a trailer to pull behind my Harley. It came with 8" Carlisle tires. They lasted more than 15,000 miles. They finally gave out on a trip to Yellowstone and I had them replaced with Carlisle tires from Walmart in Lamar, CO. By the time I got to Yellowstone, spent a couple of days there and then exited the park toward Sheridan I noticed that these tires were already worn out. Made it to Gillette where there was another Walmart with a tire store. Had less than 2k miles on the tires and they were down to the cord. Lady manager at Walmart didn't want to warranty them, but I had the receipt with the bike mileage on it that showed I'd traveled less than 2k miles. Then she tried to tell me they couldn't mount them. One of techs was walking by as she said that and said, "Yes we can". Then she tried to tell me the trailer was too heavy for the tires. I walked to the back of the trailer and picked the whole trailer up with my bare hands (total weight loaded was like 175 lbs).
She finally agreed to replace them for 1/2 price and she'd pick up the labor. That second set was worn out by the time we got back to Arkansas (another 1500 miles). I'll never buy tires from Walmart again, no matter the brand.
 
For what it is worth, my 1996 Fleetwood Prowler (GVWR 5200 pounds) has the sticker indicating load range B (ST 205/75R14:cool: and I heard that they later issued a bulletin that Load Range C would be a better choice. So I have been running the Load Range C on the trailer I have been using Carlisle tires for 20 years (not the same set :D ). They have served well and never had a tire incident.
