All 4 new Goodyear Endurance - Sidewall Failures

[Hoopy Frood]

I've always heard the "dents" were okay, but bulges were not.

Bulges in the sidewall are not OK period.

I have put man,many miles on several sets of Goodyear Endurance tires and some of them have had sidewall indentations. They are harmless and never caused me any issues. When I noticed them I looked into it.
Read the part about sidewall indentations:

Worked at Kelly tire company...the sidewall indention are where the rubber ply are joined together in the building process

Totally understand how the indentations are where they are joined together. But wouldn't it only be two right near each other? Vs. 4 to 6 on each tire? (I am no expert on this so just me asking... none of my previous radials had these or anything like this on my car hauler or previous travel trailer)

The concern I have more than the indentations as those I understand, is the outward bulges near the rim I have on 3 of my replacement tires already with only 300 miles. If its just cosmetic, no harm no foul, just has me nervous with how they look.

I left the tire company in 1985, I recall only one place on the sidewall. We did not build radial trailer tires, and maybe it has several ply splices on sidewall on today's construction. That does seem to be an extreme

We’ve had great success with the Endurance on our 303rls . i recently put our third set on and we get about 35,000 miles per set.

I will say that on our first set, I had 15 inch wheels and had difficulty getting them to maintain their PSI. They always seem to lose a few pounds just sitting in the driveway

But since switching to 16 inch wheels 2 years ago they have never lost pressure and they have held up on the road

We travel very light, and carry very little water in the holding tank

 

[Grandesigner]

I'm thinking 16s are just stronger in general. Nothing succeeds like wretched excess!

The guys at Discount Tire told me that the rubber casing of the Endurance tires are made segments in a mold that joins the segments together. Discount says this is actually a good feature for trailer tires in that most all Endurance tire failures will not result in a piece of rubber that acts like a whip and does damage to the trailer fenders and undersides. The segmented casing does, however, not look as smooth and pretty as does a tire that is made in a continuous mold.

I worked at Kelly Tire company for 15 years in the curing room. When a tire is built, the plies are wrapped around continuously on a drum to make one ply. Additional plies put together on top of each other. The plies wrapped around the tire bead. And the tread is put on top of the plies.
The tired is then put into a mold, was 2 pieces in my day, a top and bottom. Which closed on the green tire to form one piece mold. Then the tire is cured with steam and pressure.
If what you're saying that the mold is in four sections, cannot see where that would make it better. And definitely cannot see the "green" tire in four sections, as opposed to being built in one piece..

Just my two cents

The guy at Discount was implying that the mold has many segments (maybe 8 to 10?). He said that if the casing starts to come apart, those smaller segment connections will fail and not leave longer strips of casing to whip at the trailer.

The un- cured tire is built in layers to become one piece before it goes into a mold. The tire then goes into the mold. Does not make a difference if the mold is 2 pieces or several pieces After the tire is cured, the mold opens up and the tire comes out of mold ready to be used

A mold that is two pieces or several has nothing to do with making the tire better. Most likely, a segmented mold is easier to handle and do repairs on it

It would be like baking a cake

Maybe a better example would be a waffle iron

Getting new rims is a great solution.
16" rims will open up a HUGE selection of reliable LT tires.
You can sell your old tires/rims to help offset the cost.....Which will be way less than the cost of the damage a blowout can do.
It can ruin a trip.

All business' screw up. It's how they handle the screw up that I measure.

If you think Goodyear does not have a problem once in a while, then why do they have a warranty department?

 

[CampKielbasa]

With spring right around the corner, I decided to be done with the Endurances after both sets failed. Goodyear replaced the first set, but now say the second set (which is the same things happening as the first... more then just indentations, but bulges outwards) "should be okay" with a good amount of hesitancy. I am wanting to go up to a 12ply or 14ply tire vs. the 10ply E rated tire. I am liking the pricing on the Sailuns 637's 235/80x16 G rated, but cannot confirm that they will work with my Lionshead Liger wheels. I spoke to GD and they were helpful in telling me what the rims were 16X6 6-5.5 MATTE BLACK LIGER ALUMINUM WHEEL TR600HP.

Looks like max pressure of 100 PSI when I google but am finding conflicting information. Anyone have the stock rims for a 14K GVWR fifth wheel from GD and run the Sailun's or Carlisles with the G rating? I know its overkill but I am just frustrated and figure more tire wont hurt. My only guess on the failure is me essentially having to jackknife it into my driveway when I park. I know I am only creeping when I do it, but no clue why else both sets would fail. Thanks for any input!

 

[Hoopy Frood]

IMO, the sidewalls on ST tires in general, are weak. Supposedly that is so they will flex more freely than other tires. Personally I think "E" rated ST tires are pretty poor. The Sailun will work well, but you can check the rating of your wheels on the inside, under the trailer, of the wheel. There should be a specification stamped into the wheel.

FWIW, I ran my the Sailun's on my previous trailer at 90-95 psi, since I had less than 3,000 lbs./tire. They still looked good after 6 years, and were on the trailer when I sold it.

An inward indention is where the tire carcass is spliced together. When you buy a expensive brand such as Michelin, they use a filler to cover up the splice. That is some the extra cost you get for the better cosmetics. An outward bulge is a defect or a belt damage from an impact such as a pothole or a curb. Most of the time the bulge is from damage from an impact but not always. Inspection of the outside sidewall and inside sidewall will usually find the cause. Usually there is a small split in that area of the inner sidewall or damage from the tire bead being torn when the tire was mounted on the wheel.

Update to close this one down, got x4 Sailun S637's 235/80x16 delivered to my door by SimpleTire for 623$ out the door. Will have them mounted and balanced here in a few weeks and be done. Hopefully nobody else has an experience with the Goodyears like I did, which is still wild to me as they are the most expensive E rated trailer tire out there pretty much. Sailuns were almost half the price for a G rated tire.
