Tire with higher load index

[Bob Nodine]

Some additional details worth learning

Load Range E1 - deeper tread (13/32 to 15/32 depending on brand), 80 PSI max, and because of deeper tread it is about 7 to 10% heavier than C8, load index is 115

Load Range C8 - tread is 12/32 to 13/32 (rarely 14/32), 83 PSI max (Continental VanContact is 90 PSI max, WOW!), tire is usually lighter than E1, load index is 121

Both E1 and C8 maintain the same diameter (29.3), so E1's deeper tread means more rubber and make them heavy.

I went with Goodyear Workhorse HT C8. Toyo (which I have seen on many semis, tour bus and Class A) Celcius Cargo had a longer wait time, and GY was readily available - and I was already prejudiced towards GY.

If not for the inner wear which is likely due to camber/alignment issue, I must say the stock Hanhook Dynapro HT tires are great tires.

With both front wheels riding on new Goodyear, the problematic wheel was considerably hotter, the alignment issue is likely causing the tire to run hotter. So it is not Michelin's rubber quality, Discount Tire exchanged it already but I will make up with Michelin by buying Michelin tires for my car.

I have owned many Goodyear tires in my life and always had some kind of problem with them, especially on a motorhome. About 40 years ago I made the decision not to purchase Goodyear tires but have owned quite a few since then that I did not actively purchase. We had a 2007 Ford Sporttrac that came from the factory with Goodyear tires. They wore out in about 25,000 miles. Put on Michelin's and they lasted for 60,000 miles. We now have a 2023 Chevy Colorado that came from the factory with Goodyear tires and one of the tires make a womp womp noise. When they wear out you can bet I will not put Goodyear's back on.

Quick update after 5 months ---

I should have listened to you and few others that recommended against Goodyear. As soon as mounting the Goodyears on my RV there was a vibration over 60 MPH even my wife could feel from the passenger side. It was like "I dont want to touch the steering wheel" kind of feeling. I had DiscountTire balance the wheels twice and nothing worked. They mentioned all kinds of things about C8 tires and that they are known to vibrate etc. I stood my ground and replaced with Continental C8 tires (even though I did not want to go with Conti). It eliminated the vibration and it is back to the way it was. It has a 83 psi cold tire pressure rating. C8 load index and could not be happier with the tires.

I didn't have the vibration you refer to, but the new Goodride tires I bought are a lot smoother and quieter. (see post #11) It is big difference just riding down a simple road. It is almost like having new shock absorbers, and this at 1/3rd the cost of the G670s.

My issue with the Goodyears was having two blowouts within 1 year without hitting anything. Tires were 5 and 6 years old respectively.
For what I paid, I may buy new Goodrides every 4 years.
Glad you got a tire you like

Goodyear and Cooper are the only remaining tire brands manufactured in the U.S. Regardless of the name on the sidewall, tires predominantly are now made in China... like everything else. If your tires are "quiet", you probably just got lucky they were all made in the same Chinese factory. Seriously, who really knows what kind of quality control there is in tires today??

Look at the names of tires on trailers and 5ers today. Cheap and cheaper. And the ONLY reason Ford puts Dynapros on every E-Series cutaway is because of negotiated price for volume. Some are good, some are terribly unbalanced and out of round. Ford would switch in a heartbeat if a "reputable" brand underbid Hankook.

So don't overthink it. Buy a tire that's rated for your motorhome. Make sure the tires are properly balanced and frontend is aligned. Cross your fingers that they don't make odd thumping noises. 95% of tires will age out before they wear out, so it's a crap shoot.

You're not buying tires like you did 25 years ago. Brand doesn't mean anything when the same subcontracted factory is making multiple brands.

The pricing on GT Radial is mouth watering. $115???? Shipped and sold by Walmart. However not sure about that brand, may be it is because I am new to RV. Firestone (which is now Bridgestone??) is something I prefer not to consider, given the fraud allegation/conviction they faced twenty+ years ago.

Another observation is tread depth 12/32, 13/32 and even 14/32, while maintaining the same diameter - which translates to reduced volume for air. Not sure how that affects ride quality.

I had Firestone 20+ years ago peeled apart and I never went back.

Quite a few tires are made in Korea like the Hankook's.

Also Goodyear and Cooper are not the only brands made in the USA. Maybe you meant US owned companies.

MANUFACTURED in the U.S. and owned by U.S. companies...

What tires are still manufactured in the United States?
Here's what we found.

As it turns out, there are technically only two tire manufacturers we can truly label as 'American. ' The two genuine American tire brands are Goodyear and Cooper Tires. These all-American brands are physically created and manufactured in the USA and aren't owned by a foreign counterpart.

 

[dkoldman]

My goal was to replace the known Mfg who had two tire blowouts in less than a year, set at 82 psi, with no foreign object being the culprit on tires with 30 - 35k miles and 5 years old and priced well under $600/tire. Who owns the tire company is not relevant when in pursuit of safety, and one wish to not be fleeced like sheep.

The tires I bought I am sure are made in China, perhaps the largest tire Mfg in the world, I was able to get same tire tire size with a higher load index, higher speed rating, a smoother / softer ride, a quieter ride, and a DOT certification for less than 1/3 the cost. In my book, I bought from a US company / Seller via a US (worldwide customer) Portal.

If the Goodyear G670 was the exact same price, it still would not have a chance because the Goodride tire is just better. Disclaimer: The Goodrides are only 1 year old so longevity is not know known. If they stay like they have been, I may replace at 4 years just because it is not an expensive proposition.

And there you have it. We like to blame all our economic and loss of jobs on China but in fact we are to blame. We always want the best deal. When we go to the store we look for the lowest price. American companies gave us what we want by moving stuff off shore.

Only one mention of why tires get hot in thread

My F350's all came with 10 ply Michelin tires that ran close to 80k, there weren't ran underinflated, never a blow out

My F150 came with Goodyear 113 load rated that ran over 70 K not operated underinflated either. Ran them over 200k now and no blow outs

I took the Continentals off several vehicles as they were to hard to get a good grip on wet pavement

Ran Hankook's on our F550's, 16 ply and typically at 110 psig

Probably blown out more tires than most have ever owned

I have never seen the range of tire prices currently available now for the same or similar rated tire

As noted, that is because most are Chinese

Back when we were towing the Landmark we followed the trailer threads and the China Bombs were falling apart daily creating a lot of damage, apparently, they improved their quality control a bit to be marketing the volume of tires they do. We did install 15.5 16 ply Goodyears on the Landmark which were still on it when i sold it

Quite a thread showing the depth some folks think things through, I am more gitter done and be down the road

I would agree... except it's not necessarily what "we" wanted; off shoring is/was about profit margin, NOT consumers choices... nothing more.

As far as choice... I dare anyone to survive today trying to buy ONLY domestic produced products. That ship sailed to China years ago. It's a world economy now, and there's no going back to "the good ol days".
