Just purchased a set of Goodyear Endurance tires

[DR650]

I just replaced the tires on my 2005 Rockwood 21FB. The new tires are ST205-75R14 load range D (my old Marathons were load range C).
The Endurance line of tires are Made in America, speed rated at 87 mph, and have a heavier load range in all sizes.

The Endurance tires look like a good alternative to the china bombs.

Load rating obviously varies with tire size ... go to this Goodyear Endurance website and you'll see the load rating for the Endurance trailer tire ranges from 2039 lbs for the ST205/75-14 (my size) to a whopping 4079 lbs for the ST255/85-16. My trailer typically averages ~ 4700 lbs fully loaded & ready to camp, four of these tires are rated together for 8316 lbs - I think I'm good to go. :B

That is a 2000 lb difference on my trailer. I decided to stick with the Maxxis. I prefer the extra capacity.

I just went and looked at both the Endurance and Carlisle HD's. The Endurance has a lot stiffer sidewall for sure, it looks like a quality tire all the way around. I had pretty much decided on the Carlisle HD's do to the price, but man the Endurance appear to be a solid tire.

Just returned from our first trip running my new set of Goodyear Endurance tires - ST205/75 R14 - a touch under 500 km total. What an improvement in towing over the original set of offshore tires, one of which simply disintegrated all on it's own a couple of weeks ago. The trailer doesn't wag around at all, even heavy crosswinds had little effect, trailer just sat there and followed us all the way home, no drama at all. Quite happy with these LR D Endurance tires. :B

The Endurance has a real speed rating. The Marathon never did. I know Goodyear said under certain conditions, you could run the Marathons faster. However, the Endurance tires have the speed rating of the tire molded into the sidewall.

And IIRC, the Endurance only comes in D or E rating. There are no C ratings, at least in 14" or larger.

I called and tried to get some technical info regarding the differences between the Endurance and Marathon tires last week. Of course the lady on the phone mentioned a stronger sidewall and scuff guard which I can read online. It really sounds like the Endurance is just a rebranded Marathon made in the USA.

I'll agree with atlee. The testing required for a ST rated 65mph tire for the 65mph speed rating is way less stringent than testing for any other non ST speed rating. For non ST ratings, the time they must run at rated load and speed is much longer, the time they must run at above rated load at speed is longer, etc. a much more rigorous test to be able to pass the spec's for higher speed and load ratings.

IMHO based on what goodyear claims, the endurace is a upgraded replacement for the Marathon. I hope this is like the diesel truck wars of a decade ago, and we find Maxxis, Carslie, and others going to real speed and load rating on the ST tires. we will ALL benefit from more reliable trailer tires.

Let's face it, this is a wait and see situation. They've only been out six months (or so). In another couple years we should have a pretty good sample size. Why was I willing to be a beta tester? One reason as I said, is that the Goodyear Marathons that came on our Jayco did great for seven years, so I'm willing to give GY another chance. That, and they are made in the USA, and finally, the speed/load ratings work for our TT. I'm crossing my fingers, but if these tires prove themselves Goodyear will be selling a lot. Jayco has already begun putting them on new trailers.

Higher speed rating for a load carrying tire is more about the tires ability to cope with heat not necessarily how fast you can drive.
The Maxxis ST8008 are getting a bit dated with low speed ratings.....and not all sizes has the nylon cap that helps hold the tire together which is critical for any tire on a trailer with close spaced axles in the center of the vehicle. Now if Maxxis has worked for you in the past then you don't need a better class of tire.

Then.....I did some Googling. Load RATING is also known as Load INDEX.
The salesman was wrong on the size of the difference.
The GY has a load index of 123 which carries 3417 lbs
The Maxxis has a load index of 124 which carries 3527 lbs.
110 lb difference, not 500.

Perhaps the speed rating is higher with the Goodyear and the load index takes into account the higher speed. A tire engineer might be along soon to clarify the difference.

Unless maxxis has changed the tire ratings, the Goodyear has higher speed rating, 87mph vs Maxxis which between 65 and 75 mph says you must increase pressure by 10psi but not exceed max sidewall pressure and between 75 and 85mph also decrease load for the psi by an additional 10 percent. so, even between 65 and 75 you can't go with the max load rating, since you must stay below the max sidewall pressure.

BTW goodyear had the same derating for the old marathon's. And IIRC carslie and others had or have similar deratings statements.

Whereas the goodyear load index is for speeds up to 87mph.

Now if you tow, like we do, around 65mph it's a moot point, you'll be following the sidewall load rating for 65mph which is in favor of maxxis etc.

But if you tow faster, the difference may actually be in favor of the goodyear rather than maxxis/marathon etc. unless maxxis and others recently changed the load index and speed ratings.

A word of caution while comparing tires!!!!!!!
My Maxxis 8008, size 235/80 R16 are 4 years old, approx 20k miles, and one developed a slow leak. So I decided it was time to replace them. For me, better safe than sorry.
I considered the GY Endurance. I shop at Discount Tire near my home.
On the phone, the salesman recommended the GY Endurance. He said they had the same specs as the Maxxis, but a higher speed rating and a bit cheaper. I ordered the GY Endurance.
I stopped in today to make an appointment. I asked the salesman (different) to confirm that the tires were the same spec as the Maxxis. He said yes, EXCEPT the load rating was different. The load RANGE is E for both tires. The load RATING is 123 for the GY and 124 for the Maxxis. I asked him what is the difference. He came back and said the Maxxis is rated at 3500 lbs per tire and the GY is rated for 3000 lbs per tire. That is a 2000 lb difference on my trailer. I decided to stick with the Maxxis. I prefer the extra capacity.

Here is an article from Discount Tire about it: https://www.discounttire.com/learn/load-range-load-index

I am sticking with the Maxxis. I had good luck with them and it handles 440 lbs more than the GY. Again, I opt for the extra capacity.

FYI...On the sidewall of the Maxxis, it says Max load single 3420 lbs, max load dual 3010 lbs.

Cheers,

I just returned from 6k miles on my new set. Most of the miles at 100+ degrees.

No issues. Still look new.

I did the exact same Endurance changeover thing C to D and same size just before I left Southern Cal for my Alaska trip in May. Still on the trip traveling down west coast 101. Even after some really long bad roads, and about 9000 miles to this point, the tires look great. I will buy them over and over again. This test was a great test for the Endurance.
