Blowout on Goodyear G670

[Outlaw2020]

July 8, 2017 I was traveling to Dallas to Rangers game on I-20 in '08 American Eagle motorhome. I had just got on I-20 from Toll 49 when left front steering tire blew out. I had just passed a truck and was in left lane( probably going 70 mph)when it blew. Pulled me into median.It was all I could do to try to keep it from going straight left. How it didn't turn over, I don't know, was in there 400-500 yards before I could get it under control and eased back on Interstate and crossed over to Hwy 110 exit and parked in front of a convenience store until I could receive help. Eventually got another tire from Goodyear Commercial Service Center. Upon returning to home, app 50 miles, I took it to the body shop to have damage repaired. The owner said this was the third Goodyear G670 tire he had seen blowout in last month. I live in small town of less than 14,000 population. My tires were put on new in October, 2013. The other two guys tires were 6-7 years old. The tire Goodyear put on was a 2015 tire. Didn't see that until I got back. They would not exchange it. The tires on coach were 3 years 9 months old with 17,000 miles on them. They are supposed to have a 5 year warranty. I will be replacing all tires(including the $1180 new replacement) with Michelins. Has anyone had similar experience?

To the OP.

Do you have a safety steer on the front linkage? It is said that this will prevent the situation you described (or at least minimize).

Anyone else with safety steer that would be wiling to share their real life experiences with front end blowouts would be nice.

Thanks.

Outlaw, just curious, did you mash on the accelerator pedal when the tire blew?

It is a hard instinct to follow but it has been said over and over to press on the accelerator to gain control then ease off once you can manage the coach.

You are talking about a video put out by Michelin. I have looked at it a number of times on various forums. It makes no more sense now than when I first saw it. It says your first action with a front tire blows out, is to step on the accelerator, I totally disagree. I've had two blow outs, the most recent was a RF tire in May 2015. The last thing I wanted was more speed or more forward thrust. There was a pretty rough vibration in the steering wheel as well as a pull to the right. I slowed (did not brake), maintained control and got off the road. The Michelin video sounds good and looks good, however, all the scenarios are scripted with safety the primary consideration. It's like a lot of "school solutions," every aspect of the demonstration is planned. However, when doing it for real, I doubt it's merit.

Blaster Man, I'm certainly not an expert and hope that I never have a blow-out. I do find the video interesting and it does make sense to me.

As mentioned in the video, mashing the accelerator does not really build speed, it just takes the hard driving force way from the flat tire giving you more control. That seems like a good idea.

Everyone should do what they feel is the safest. If I remember in 'that' moment of panic, I'll try to hit the accelerator.

Here is a link to the video for those that have not seen it.

I'm sure everybody has seen the video of the MH in the passing lane, the LF tire blows, the coach goes into the median, and rolls over. I'm sure the driver was not even thinking about mashing the accelerator, he appeared to be driving a bit fast and the last thing he needed was more forward anything...he needed to slow down and get rid of that speed, without braking. With the power steering on these coaches, control was not a problem on my blowout, just some back and forth vibration...which probably would have gotten worse with more thrust. I don't buy Michelin's video, with any vehicle that is nearly out of control, as evidenced on the above incident, more forward thrust or speed is the last thing you need.

The Michelin tires that have sidewall failures were the XRV model. These tires have two ply sidewalls for a cushy ride. When my left front Mich XRV blew the sidewall, I thank God that I put an old "knuckle knob" on the steering wheel. Mich decided not to help replace the defective tire. They did tell me that they were a tire wholesaler and does NOT have suggested retail prices. I was so happy with that conversation, I ran out and bought Toyo's. Not the least bit sorry for that decision.
Toyo now has a plant in the US.

I have no data to prove to disprove that claim, however I will say the number of Michelin failures reported here has dropped off a bunch in the last 10 years. I will also say the last set of Michelins on our MH gave us years of excellent service - something I can't say for any other Michelins we've ever owned.

A few months ago I was asked why I wasn't a Michelin fan, my answer can be found HERE.

Been running Bridgestone tires on our coach now for 16 years with no issues. (knock on wood)

Best Regards to all and safe travels....:)

I hope to not find out as we replaced our Michelins with Bridgestones - so far so good!

I've had two blowouts in an RV (tag and inside dually), both were with GY 670's, 6 and 5yrs old respectively and both in NY. Having said that, I'd first blame it on NY, before GY and with all the road hazards on the thruways. Especially since I keep them aired up and then some. Having said that, I'm convinced that no other tire, including Michelin would guarantee better results and also that no Chinese tire would do any worse.
History and care are important with any tire, but with these two instances, I personally cared for the first since new and with the second, there were two previous owners, right before we purchased, so.......
As for the 75mph speed limit on these tires, for me to even approach that, is mind boggling, so doing 70 in a motor coach is out of the question for us and reserve that kind of speed for our cars, if even then. In the old days, trucks and buses were limited to 60 and when they had it right and most sure the braking and handling still isn't on par with a sports car. I also believe that the truck speed limits are a result of lobbying and it's still all about money, despite what concerns the government might have for safety.

You never know until it happens, but more speed was not what I wanted. It is good to think about what you will do, but instincts take over. Surprised that people are running tires on RV 10 years old.43,600 lbs is a lot of weight. I was also towing a Jeep Wrangled. It came through unscathed.

I replaced my last 22.5" G670's when they were 10 years and 3 months old with another set of G670's. That was 2 years ago. Don't know where the OP paid $1,180(rip off) for a tire. But mine cost me $524.30 each out the door, mounted, balanced and taxes.

Before the G670's my MH had Michelin XRV and I had 2 zipper blow outs with them before I replaced them at 6 years 8 months old.

One of the flats was a right front. No damage but I did use the Michelin video on hitting the gas when the big bang happened. I went straight and no problem controlling the steering. Or maybe my Safe-T-Steer helped.

[Outlaw2020]

Thanx for all insight. No, I did not accelerate, just fought wheel from going hard left and ride it out until it slowed down. Also have been told not to brake. Sorry to hear dissatisfaction with Michelins. I purchased tire insurance from LazyDays (Tirerenu)when I purchased Coach in 2013. I have not heard d back from them. Will post here final results. Doesn't Family Motor home Coach Association have a similar product.?

[Outlaw2020]

I have pressure indicators on each tire and manually check pressure before each trip. I did not run over anything. I too have heavy equipment and 10 trailers. Maintenance is top priority on all my equipment with tires on top of the list. This was clearly tire failure...Was very dissatisfied with Goodyear. The others tires are 3 years 9 months old and are all being replaced with Michelins. Thank you for your response.

[moisheh]

GY670's fail because they are junk. Owners who replace them with almost any other tire cease to have problems. To make matters worse GY never admits there is a problem with their tires.

Just to add a little personal insight - if many tires have failed in an area it is often due to Many Things Being Left In the ROAD - Road Hazard - Just a personal observation, from my many years and many miles on the road.

Generally - tires fail because they Hit something or they Have Low Pressure- thus overheat and Fail.

Being one of those OLD Fa*ts who was a contractor and would use tires for tens of years not just years - I can never remember a tire failure that was not due to either Road Hazard or Pressure Hazard.

Having been in the Heavy Equipment Business for 30 years - having probably 40 Trucks or trailers on the Road, requiring drivers to check tires every morning and often in the Afternoon for tire pressure. Having tires that lasted for decades, not just years, I am still amazed at the number of "Failures" RV'ers have - these RV's/Trucks/Buses are not the same as the car you drive they need you to be vigilant, and to understand how critical it is to not just Drive, but to be a Driver, be responsible for the Vehicle you are in.

Sorry, rant over, Yes tires do fail, and I'm Thankful no one was hurt in this case, But RV'er just seem to have an unusual number of tire "Failures". Keep your pressure correct - watch the road - Be Safe.

JMHO,

Welcome to RV.net and Tires is probably the most often hotly discussed issue. Glad everything turned out OK with your blowout. Many on here will only buy Michelin or Goodyear because they were original equipment on their coach. Others will not go back with them when they replace because the Goodyears often have excessive edge wear and Michelin's often have excessive sidewall cracking. I'm in the never Michelin camp, not because of the cracking but because they would not warranty their XRV tires that were indeed so sorry some did indeed blowout sitting still. This is after four decades of loyal Michelin use…fortunately there are plenty of good alternatives out there today.

Many have gone to Handkook, Toyo, or Yokohama with good success...I have at almost half the price of the big two. In my many years on here I have never heard anyone badmouthing those three, although some of that could be the limited numbers compared to the big two.

For those in the never Chinese camp I would suggest Firestone/Bridgestone as a good alternative. My dilemma is my Firestone FS 400 tires look so good at seven years I'm tempted to go longer on the front of my motorhome...no cracks in them and plenty of fairly even tread left. I am happy with the six Hancook's on the rear of my motorhome after four years.
