Anyone else have a blowout like this?
60k on tire..
60k on tire..
Good year tires GRRRH
- Thread starter mrgoodtude
- Start date
Looks like sidewall separation....foreign material or moisture caught between the tread and the last ply ....see i used to build tires and worked in final inspection at Firestone....
As you see where the gap (blowout) is the tread layer has not bonded to the ply below it....It starts out as a small area and gets bigger or separates more till the inside pressure blows out at the weakest point. Unfortunately its nothing that will show in the inspection stage.

We have gone back to Michelin's on the steers all the difference in the world..
Goodyear's on drives are original equipment and will probably swap at 400,000...

good grief .... wednesday morning doing my post trip after doing a ft smith to evansville noticed a flat spot in the center of the tread. after consulting with my mech over the phone decision was tread seperation causing strange wear. tires were bridgestone 380's. guess what tire was on sale at the tire store... yep goodyear. two new steers for just a little less than 800 installed... sure wish i'd seen this first.

i think maybe we all need to reread OntarioVanMan's post
it appears it's a problem all munufatures deal with that there is not a type of inspetion that will detect it.a fly or even a drop of sweat will couse this,thats how i read it anyways

They probably could detect it if they x-rayed every tire...but thats not cost effective....The worst tires are the ones usually made in the hot summer months.....most have a moulded serial number with Month/yr/machine # down by the bead/rim...if made in Canada there will be a little maple leaf.
Any foreign material trapped between the last applied ply and the tread has the potential to cause tread or sidewall separation.
Also a drop in cure temperture or steam pressure could cause a minute amount of incomplete cure time.....where the plys don't really bond 100%.
Considering the volume of tires manufactured everyday...the failure rate doesn't even show on a graph....But if it happens to you...it's misery.
I don't know how far they've come but if you can get them with the teflon belt anything but steel...is the best.....cop tires are made of this....steel will overheat and the belt will warp and or separate causing a blowout.

I have the same Good Year tires and haven't had any problems with them, they hold pressure well also. the tires have 145,000 miles on them.

Don't know about the MFG date (is that stamped on the tire?)
Spuds 145k? that's awesome..
We run a Volvo 780 that is heavy on the steers so we went with a 16 ply Michelin this go around but still won't get anymore than 110k use out of them..
OVM thanks for the great info kinda scary that the QC process for steer tires does not differ from the drives

Mike...I worked on the truck and bus radial line in the cure process and final inspection and when Goodyear was on strike we made theres as well....Cooper, Shell, Fina, Sears...military.
There is NO designation for steer only tires...they are all made to the same high quality standard!
Serial number should be on the inside(blackwall) by the rim/bead area...

I had a Freightliner Century, before I bought my Western Star. The Century was heavy on the steer axle, if I got 100K on the steers I was happy. Even though Western Star is made by the same parent company the difference is unbievable. Everything on the Western Star is top shelf. I would recommend a Western Star to anyone looking to build a class 8 expediter.
I did a little research with another dealer who builds expediter trucks. They wanted to put me into a M2 112, with a Cat C9. I told them I wanted an MBE 4000 series engine, they said it would cost me $12K more, bringing the price of the M2 to the same price I paid for the Western Star.
I don't care what any salesman tells you, a freightliner M2 is a regional haul truck, and the Cat C9, Cummins ISC, and MBE 900 are regional haul engines. They are not made for long haul. The kenworth T300, and Petebilt 335 fall into the same catagory.
I have talked to the truck reps., and engine reps. at the trucks shows, not the dealers who sell the trucks, but the manufacturer reps. To a man/woman, they have agreed with me, especially in team operations. They have all told me that a class 7 truck was not made for long haul or team use. And that even though the M2 112 and C 9 are class 8, they are still a regional haul use vehicle.
I know a ton of people will disagree with me, but after my own research, and talking to the factory reps, and the techs who work on the trucks, I wouldn't even consider a class 7 truck, or the M2 112.

okay so i read this and did a close look over of my tires. i found a small bulge in the lr. i called gy and drove 45 miles to have it looked at. the desk guy said it was in a spot where the tread bar is located. he then pointed out a small indentation where the next wear bar should be located.
ken, my question is,.....how do you tell a tread wear bulge from a delamination of the tire and inside wall?

just getting off that 666 post number. nothing here to read.
Jack...the treadwear BAR is not a bulge as in a tread or sidewall separation or bulge in trucker lingo....a tread bar is just that, a SOLID ridge of rubber built in to the tread...there should be a line all the way across from one side to other...some tires have four built in and others will have just two. Also I should add...sometimes theres what is called tread separation caused by overheated tires...main cause is steel belt hot day long highway run....The steel heats up weakening the bond to the tread ply and bango theres your blow-out...also steel when overheated will warp sometimes causing your wbbly tire syndrome ...thats why IF they are available go with a Teflon or nylon belted tire...opposed to steel...
Athens Ohio last Nov I blew my first Good Year Steer Tire
Only the whole tire blew off the rim on my FLD and the Ohio State Trooper that Witnessed the whole thing about **** his pants so he said as he thought The whole truck was going into the Ditch. I was running 50mph and was comming down the hill in athens Ohio when it blew. I know my speed as the Trooper told me what it was as he was spotting me on Radar Lucky for me I remember what Jeff Fox told me In CDS (He Pulled Tankers) Said never get on the Brakes get a good grip on the steering wheel and steer straight and if on a down hill goose it and keep ur front end back up then let off the throttle Well That was what I did. Hmm the Second Steer tire blew 3 weeks later in Florida on the Turn Pike running 70 miles an hour. Needless to say it was the same Brand Good Year and the same Number shown. That tire too came completely off the rim.
Far as Im Concerned I will not even consider a GOOD YEAR Tire again. Not for Steers at least.

After the first tire blew did you replace both steer tires or just the one? Steer tires should always be replaced as a set, and with the same brand and tread design.
That being said, there are many factors that can lead to tire failure, the number one reason is improper tire inflation, especially low inflation. under inflated tires is the number one cause of tire failure, so I have read, and beleive. The extra flexing the side walls have to do and the extra heat build up in tires can cause tire failure in relatively new tires
