Louisiana Tire Regulations

Wheels and Tires - Must have at least 2/32" of tread measured in any 2 adjacent major grooves. No knots, bulges, sidewall cracks or tread exposure allowed.

Restrictions as to tire equipment

A. Every solid rubber tire on a vehicle moved on any highway of this state shall have rubber on its entire traction surface at least one inch thick above the edge of the flange of the entire periphery of the rim of the wheel.

B. No tire on a vehicle moved on a highway shall have on its periphery any protuberances of any material, other than rubber, which projects beyond the thread of the traction surface of the tire.

It is permissible to use tire chains of reasonable proportions upon any vehicle, when required for safety because of conditions tending to cause a vehicle to slide or skid.

C. The department may issue emergency permission authorizing the operation upon the highways of traction engines or tractors having movable tracks with transverse corrugations upon their periphery, or farm tractors or other farm machinery or instruments of husbandry.

Note onTire Width: There’s no legal restriction on the width of the truck tires themselves, but they’re not allowed to extend beyond the fenders of the truck in virtually every state. One simple and perfectly legal way around this is to put fender flares on the truck that are wider than the truck tires. These are counted as part of the fender, so extremely wide tires are legitimate as long as they don’t stick out beyond the fenders.
