Is this tire DOT legal?

no picture.

 

probably not legal, but not sure.

those are some big chunks!

 

CFR 393.75
The Code of Federal Regulations (CFR) 393.75 describes eight specific parts involving truck tires.

“No motor vehicle shall be operated on any tire” that:
• Has body-ply or belt material exposed through the tread or sidewall
• Has any tread or sidewall
separation
• Is flat or has an audible air leak
• Has a cut to the extent that the body-ply or belt material is exposed

 

This is the search I did: "fmcsa tire tread depth regulations"

FMCSA, CVSA and tread depth | FleetOwner

FMCSA regulation
According to Federal Motor Carrier Safety Administration (FMCSA) regulations, the minimum tread depth for a steer tire is 4/32 of an inch on every major tread groove. If one spot on one groove is less than 4/32, then a driver will be issued a citation. The thin decoupling groove at the shoulder, however, is not a major groove. It can theoretically be worn away and the tire will remain in compliance as long as the major grooves are 4/32 when measured anywhere on the tire and there are no other conditions that warrant a violation. These same rules apply to drive and trailer tires, but the minimum tread depth is 2/32 of an inch in every major groove. It’s also important to note that the tread depth measurements cannot be taken at the wear indicators or stone ejectors in the grooves.



I think you should take that tire off and have it section repaired or total recap. (Not sure of correct explanation).
I think you would be put out of service and possibly get a fine.

 

No beuno. Time to replace.

 

gonna be sarcastic here, but naw,go ahead and run it , seems round, has air,98 % tread left, no problem ,just let me get in front or way behind before it goes.
