Tire question

What is the tread depth at the wired spot. From what I understand, DOT doesn't care about irregular wear as long at the depth is sufficient and there are no cuts. Irregular wear will how ever damage the tire and need replacement sooner. It most likely is not inflated properly or is not aligned properly.

 

I'd keep on rollin.

 

A trailer tire is out of service for tread depth when the tread is:

So worn that less than 1/32 inch (.8 mm) tread remains when measuredin any two adjacent major tread grooves (typically any groove containinga tread wear indicator) at 3 separate locations around the circumference​

of the tire at least 8 inches apart.

I cannot tell from your picture whether this is the case.

 

If that is all you got, you are fine as long as no wire is showing.........Roll on!

 

Ummm,...FMCSA RULE that states < 1/32 for trailer tire Please???
Ummm,...FMCSA RULE that states two adjacent major tread grooves Please???
Ummm,...FMCSA RULE that states at 3 separate locations around the circumference of the tire at least 8 inches apart Please???






§ 393.75Tires.
(a) No motor vehicle shall be operated on any tire that—

(1) Has body ply or belt material exposed through the tread or sidewall,

(2) Has any tread or sidewall separation,

(3) Is flat or has an audible leak, or

(4) Has a cut to the extent that the ply or belt material is exposed.

(b) Any tire on the front wheels of a bus, truck, or truck tractor shall have a tread groove pattern depth of at least 4/32 of an inch when measured at any point on a major tread groove. The measurements shall not be made where tie bars, humps, or fillets are located.

(c) Except as provided in paragraph (b) of this section, tires shall have a tread groove pattern depth of at least 2/32 of an inch when measured in a major tread groove. The measurement shall not be made where tie bars, humps or fillets are located.

(d) No bus shall be operated with regrooved, recapped or retreaded tires on the front wheels.

(e) A regrooved tire with a load-carrying capacity equal to or greater than 2,232 kg (4,920 pounds) shall not be used on the front wheels of any truck or truck tractor.

(f) Tire loading restrictions (except on manufactured homes). No motor vehicle (except manufactured homes, which are governed by paragraph

(g) of this section) shall be operated with tires that carry a weight greater than that marked on the sidewall of the tire or, in the absence of such a marking, a weight greater than that specified for the tires in any of the publications of any of the organizations listed in Federal Motor Vehicle Safety Standard No. 119 (49 CFR 571.119, S5.1(b)) unless:

(1) The vehicle is being operated under the terms of a special permit issued by the State; and
(2) The vehicle is being operated at a reduced speed to compensate for the tire loading in excess of the manufacturer's rated capacity for the tire. In no case shall the speed exceed 80 km/hr (50 mph).

(g)(1) Tire loading restrictions for manufactured homes built before January 1, 2002. Manufactured homes that are labeled pursuant to 24 CFR 3282.362(c)(2)(i) before January 1, 2002, must not be transported on tires that are loaded more than 18 percent over the load rating marked on the sidewall of the tire or, in the absence of such a marking, more than 18 percent over the load rating specified in any of the publications of any of the organizations listed in FMVSS No. 119 (49 CFR 571.119, S5.1(b)). Manufactured homes labeled before January 1, 2002, transported on tires overloaded by 9 percent or more must not be operated at speeds exceeding 80 km/hr (50 mph). (2) Tire loading restrictions for manufactured homes built on or after January 1, 2002. Manufactured homes that are labeled pursuant to 24 CFR 3282.362(c)(2)(i) on or after January 1, 2002, must not be transported on tires loaded beyond the load rating marked on the sidewall of the tire or, in the absence of such a marking, the load rating specified in any of the publications of any of the organizations listed in FMVSS No. 119 (49 CFR 571.119, S5.1(b)). (h) Tire inflation pressure. (1) No motor vehicle shall be operated on a tire which has a cold inflation pressure less than that specified for the load being carried. (2) If the inflation pressure of the tire has been increased by heat because of the recent operation of the vehicle, the cold inflation pressure shall be estimated by subtracting the inflation buildup factor shown in Table 1 from the measured inflation pressure.Table 1—Inflation Pressure Measurement Correction for Heat[TABLE="class: GPOTABLE"]

Good one Rawze. I guess a couple of locations less than 2/32 is OK, but not if they're closer than 8". I just had this issue on a tandem tire, a new Michelin. I think sometimes when those gladhand clips are loose, they'll vibrate loose and make those long black skid marks. (on the pavement, I mean) The debate of what is a "major tread groove" is valuable. I take it those major grooves are in the tire center. 2, or 3, or 4, or 6 - kind of depends on tire type, looks like.

 

You need to understand that CVSA sets the Out of Service Criteria, based on the regulations from FMCSA.

For the details of what will put a vehicle "Out of Service" after a DOT inspection, please see the current OOS criteria from CVSA.

 

So,...Please,...Entertain us,...



Ummm,...OOS criteria from CVSA that states < 1/32 for trailer tire Please???
Ummm,...OOS criteria from CVSA that states two adjacent major tread grooves Please???
Ummm,...OOS criteria from CVSA that states at 3 separate locations around the circumference of the tire at least 8 inches apart Please???


Educate us ignorant common folk,..please,...because I have in fact been cited for a tire in the past that did not qualify FMCSA. As I am sure a few million other drivers have.

The ACTUAL regulations please???

The orig. question WAS for the concern of OOS and not just a citation,...A CITATION CAN BE JUST AS BAD SOMETIMES!, depending on what company they drive for.

 

Entertain you... it doesn't sound from your snide comments that I could possibly entertain you.

Of course the original question was about OOS tires, which is why I quoted the 2013 CVSA OOS regulations, section 10 paragraph b(11).

Please obtain a copy of the current CVSA OOS regulations and look it up yourself. Who knows? It might even entertain you...
