DOT & FMVSS Rules for Imported Tires: USA Compliance Guide

Selling imported tires in the U.S. isn’t just about price and duty — every tire you bring in must meet federal safety standards. For dealers and resellers, buying compliant new tires protects you from liability and unsellable inventory. Here’s what DOT and FMVSS require, in plain terms.

The two safety standards that matter

• FMVSS 139 — new pneumatic tires for light vehicles (passenger & light truck).
• FMVSS 119 — new pneumatic tires for heavy vehicles (trucks, buses, trailers, and most off-road).

These are issued by NHTSA. Any new tire sold for U.S. road use must conform — regardless of where it was made.

The DOT code (Tire Identification Number)

Every compliant tire carries a molded DOT TIN on the sidewall. It confirms the tire was built in a facility registered with NHTSA and encodes the plant, size, and the week/year of manufacture (the last 4 digits). Buyers and inspectors read this code to verify age and origin — so it must be present and legible.

What a compliant imported tire shows on the sidewall

• DOT TIN with a valid plant code and date code
• Load index & speed symbol, max load, and max inflation pressure
• Construction (radial/bias), ply/material, and size designation
• UTQG treadwear/traction/temperature grades (where applicable to the tire type)

Why this matters for bulk buyers

Non-compliant or improperly marked tires can be refused at the border, can’t be legally sold for road use, and expose you to liability. The simplest protection: buy new tires from a supplier that produces to FMVSS and stamps a valid DOT TIN. Every tire we supply is new and built to these standards — see how we source in our bulk tire export overview, and the cost side in our import-duty guide.

Frequently asked questions

Do all imported tires need a DOT code?
Any new tire sold for U.S. road use must meet the applicable FMVSS and carry a molded DOT TIN. Tires without it can’t be legally sold for road use.

What’s the difference between FMVSS 139 and 119?
139 covers light-vehicle (passenger/light-truck) tires; 119 covers heavy-vehicle and most off-road tires.

How do I read the tire’s manufacture date?
The last four digits of the DOT TIN are the week and year (e.g., 2625 = 26th week of 2025).

Are off-road/ag tires covered?
Most heavy and off-road tires fall under FMVSS 119; requirements vary by type, so confirm with your supplier.
