Ugh - more trailer tire talk, Goodyear Enduance

[tuffr2]

I am looking at buying a new travel trailer. In the old days, like just a few years ago trailers came with China Bombs ST tires rated for a max speed of 65MPH.

Now there are trailer tires that are rated at 75 and 87 mph. One tire that was talked about as being a good tire is the new Goodyear Endurance trailer tire. So I started to reseach this tire. It is made in the USA and is 10 ply.

I researched tires 4 years ago and bought expensive Michilin XPS Ribs for my trailer. The speed rating was 87mph. I am now glad Goodyear is now an option.

I found this as interesting. New (ish) Speed ratings on trailer tires.

You could always just pass by a topic if you find it "tiring".

I do not think it is boring but maybe the forum members are bored. I posted this because of the speed rating of 87 mph that is new to me.

I did not know that. Plus the article screen shot talks in a general sense that a lot of trailer tires are 75 mph tires. Again, something else I did not know.

I didn't know this, and we might all want to verify before driving faster. I thought the Goodyear Endurance tires were rated to 65 like the others, but were simply better quality.
I would love to be able to go 70 on the interstate.

Oct Prime - I too am happy that I will be able to tow at 70 - 72 mph with these tires. And happy a US company is making them.

I would love it if my trailer could go 75-80 mph, but it sways real bad at 55-60 mph. I keep trying to go real fast but just can't.
So I just run the ole St bombs. No point in getting 87 mph tires when my trailer can't go that fast.
How do you guys that run 75-80 mph do it? Do you have special trailers?

My original China-poppers were D-load and only rated at 65mph. I've had the E-load Endurance tires on ours since Feb last year, with about 8K miles on them. They are rated at 87, and I usually pull 70-72 on the interstate. I like having extra room between what I run and what the tire is capable of. Mine pulls great at that speed, with zero sway or wiggle, and I don't become a running roadblock for the rest of the traffic. It seems running at 60-65 on an interstate where the speed limit is 70 mph leads to folks flying around you, whipping in front of you, horns blowing, etc. I would rather go with the flow of traffic. Of course, I'm not advocating everyone should run that fast, you should run what you are comfortable with, what you equipment is rated for, and what your vehicle will safely handle.


Cumminsfan, your sig doesn't list what you are pulling or what you are pulling with. If you are getting a large amount of movement and sway at 55-60 mph, I would say there is something not quite right with your set-up, be it your loading is taking too much weight off the tongue or your WDH needs some tweaking, or you may have too much RV for the tow vehicle. But you should be rock steady up to at least 60mph.

With out getting into a big debate on tires.
The Endurance tires are N rated when used as a temporary spare tire. See speed chart. I checked tirerack website and various other tire sites and they confirm N rating. But most do not incidate for what application. So I would suggest that the 87 mpn is for short periods of time only, not for the long sustained drives. Not sure what the speed range would be if your using them on a regular basis.
The devil is in the details.

Your chart is one line off. The "Temporary spare tires" line should be by the M-rating, not the N-rating.

Boredom has nothing to do with it. Its the repetition.

Goodyear is an American company and has produced its own 'bombs' and currently has its own ongoing law suit related to its tires put on MHs. That doesn't inspire me to buy their products.

I suspect a lot of the issues with trailer tires has more to do with owner misuse and abuse than country of manufacture. But how many owners are going to publicly admit that? Its much easier to go on the internet and simply say it failed because the sidewall said made in China therefore some sort of proof. Goodyear marketing has noticed because their previous ST Marathon tires were also made in China. The Endurance has only been out for a little over a year so still pretty new. Time will tell if they are truly better than the rest or just an over priced also ran.

Perhaps this article is new to you as well: A blog post from tire engineer Roger Marble: Causation or Correlation. The last paragraph sums it up nicely.

Your right for tire rack they left the application blank...on tirebuyer.con website they have it different. Go figure?

Bottom line is tire buying is confusing and Heat is the tire killer.....and imho country of manufacturing has nothing to do with the quality of a product.

Good comments and feedback..and agree with your comments about customer tire maintenance.
I like to be speed limited when towing by common safety sense.

Mission Statement: Supporting thoughtful exchange of knowledge, values and experience among RV enthusiasts.

If someone has a question or concern or information to pass on, let them post, with the rest of us responding in the spirit of this site's mission statement. There is so much experience and willingness to help on this site that I find it invaluable . There are so many topics, issues, concerns, etc, that most all of us can find an area to which they can apply their personal knowledge and experience and assistance. So, since there is no such thing as a dumb question, I certainly hope that members continue to step forth so that they can learn and/or share their knowledge.

As to TT tires, I have always fretted about a blowout. I'm not sure which is more important to towing, the right TV, the right hitch setup, or the right tires (TV & TT), irrespective of one's manufacturer prejudice. I'm always up for more thoughtful exchange on these topics. Since I now have the Goodyear Endurance on my trailer, I feel more at ease with each positive posting and discussion on this site. Even negative information can give me a heads-up if I can or need to do or consider anything differently. IMHO, improper inflation, failure to inspect, and heat (meaning speed) are the culprits in most tire failures. I'm not discounting poor design, faulty manufacturing (good reputation as to design & manufacture can influence my future purchase decisions), or road hazard, but these are beyond my immediate control. The other three are not. Thanks all.

Be safe!
