Truck tire debris

[284 International]

Here's the thing, I would never consider a truck tire to be properly inflated at 30 psi... The term "properly inflated" seems to be more subjective than objective.

I agree about the subjective part. I don't want to change the topic from tire debris; I run my tires at 42 PSI. Recommended is 35. (Same brand/model tire as factory delivered)

After mine decapped, the inside part of the tire bulged out beyond where the normal layer of tread would be, looking just like a thick inner tube would. It was round in profile. I surmise the extra volume caused the pressure decrease, in part. I checked the tire's pressure that evening after I got home. Within a couple days it was flat, so it obviously had a leak, too. The point is, I wasn't running it at 30 PSI, and didn't make that clear in my earlier comment. (Having said that, even if it were at 30 PSI, I don't think the tire should fail like that after 5,000 miles on a new tire, when recommended is 35)

The tire was on a gas 1/2 ton pickup, so was not heavily loaded. It had enough tread left to talk half of US penny's diameter, so was certainly not worn out.

I am not a tire technician, so will not say that the tire could not have been under inflated. But I don't think that 7 PSI over the factory recommendation for the tire should result in that kind of failure. The tires are rated to 65 or 80 PSI maximum inflation, so 42 PSI didn't over stress them, either. The remaining 4 tires of the set (I had bought a full set plus spare) ran another 45,000 miles at 42 PSI.

I don't mean to hijack, or be snotty; I just wanted to expand a bit on what I had said, since it lacked context in my earlier post.

Yeah, recaps get a lot of blame, but many many years ago, a study was published that made a lot of sense to me. Look at the rubber that's on the road. Does it show signs of the tire cords? Most do, but wouldn't if it were the cap and not the body of the tire. Of course you may say that the recapping process weakened the tire and caused it to blow out, and I'm sure not expert enough to contradict that, although some who are experts have claimed it isn't so. It's been quite awhile ago when one of my brothers owned a couple of 18 wheelers and he once said the best tires (at that time) that he'd found was to run new Michelins 40k miles, recap them (Bandag recapping), and run them another 60k miles (yep, the recaps outlasted original tread).

My only personal experience with recaps was when I took two Gates tires to be recapped, then put them on my 1956 Mercury Montclair convertible in 1958, and in spite of a lot of hotrodding, they never gave me any problem. Then in 1960, I bought 4 recapped tires to put on my Studebaker Silver Hawk. Again, no problems.

Good point sir. The recap tire is only as good as the people who recapped it. And if it's new or recap inflation is still critical.

284 International, good to hear you don't run them that low! I am a firm believer that a tire will be damaged much more by under inflation than over inflation. Factory air pressures seem to be more aligned with a soft ride than anything else.

About 3 weeks ago I made a trip to Indiana and back, and yesterday I drove to southern Detroit and back, both trips were about 230 miles total. Most of the miles I drove were freeway miles, and to me it seems this year there is a LOT more truck tire debris along the shoulders than I recall ever seeing in past years. In all the distance for both trips I only saw a few chunks of smaller rubber on the roadway itself but there must have been hundreds of partial treads on the shoulders. Perhaps it's just my perception but I cannot recall ever seeing so much truck tire debris as I have recently.

Thankfully, we have never sustained any damage that I know of to any of our vehicles, but the last time my in-laws drove to Nashville, their late model Buick got hit with a large chunk of rubber in the bottom of the front fascia...and they said it is a $300 repair. Have any of you sustained damage from hitting tire debris?

JD,

Twice in the past year. One was a large piece of rubber thrown into the air by a vehicle. I could not safely dodge it, so it hit my grille and hood denting both, plus warping my front license plate. The second was a piece that also dented my hood. Another just missed as it skimmed my roof. Many people do not dodge these items because thank do not see them as they talk on the phone or text.
I travel about 300 miles round trip of interstate each week and also find there is more rubber (with metal mainly) tire debris.

OR they follow the vehicle in front of them so closely they cannot see any debris on the road. I drive (pun intended) my wife nuts while in traffic on the freeway sometimes because I often speed up or slow down to stay out of packs of other vehicles that are all following each other too closely.

Just rolled down to Mississippi from DC yesterday.
Definitely lot's of tire pieces.
It seemed that there were more tire pieces, especially on the shoulders, where the grass was taller, and most of the 820 miles the grass was taller than prior trips, suggesting less state maintenance.

I too strongly believe in leaving a big gap between me and the car in front.

In another thread:

I may have posted this before but:
About 20 years ago I was driving my Dodge B120 van down to Kings Dominion for a fun day at the waterpark. I had three boys with me, from about 9 to 13.
We were in the middle lane, moderately dense traffic, about 65 mph.
A boat trailer in front of me lost a right wheel, one of two.

The darn wheel and tire flew up in the air, probably 30 feet high and coming directly at me. I couldn't swerve to either side without hitting a car. I floored it and hoped for the best, trying to get it so it would hit the roof instead of the windshield. Didn't have time to get scared, just time to react.

It hit dead center above the window frame and left a dent about an inch deep, bounced off and was someone else's problem.

It was just like heading a soccer ball.

Didn't even have to change my pants.

Last year I had just passed a truck hauling 3 rolled bales of hay when 1 rolled off into the car following closely.

If you don't leave time to react you and your passengers might be dead.

I've seen numerous large road snakes thrown up from underneath compact cars and can just imagine what happened to their undercarriage.

In 1991 I was driving my first new car 1991 5.0L mustang on its first road trip. Hit a piece of recap and scratched the side above the passenger tire.

Yep...used to drive a Tahoe and could run over the recaps in the road...Tahoe no more and in a VW Jetta TDI now...my entire front grill/ground effects were bashed in until I finally rear ended a car that slammed on brakes as it came around a turn...fixed now :/

I'm retired from ODOT, and have thrown bunches of 'gators off the road. I learned pretty quick to wear a pair of gloves too, as some are still pretty hot..!! Most seemed to be caps off trailers. When it gets near 90 degrees, you can pretty well count on the highway being littered with them.

A buddy of mine and his son haul container trailers. Seems the owners of the trailers hate to spend too much money on higher quality tires. He had a brand new installed Chinese tire peel off, after about 80 miles. The mechanic had just finished putting it on as he pulled up to hook. He double checked the tire pressure, as the driver is responsible for buying a new tire, if it sucks the tube.
