INBOF 4 Pack Tire Tread Depth Gauge

Keep one in your car for added peace of mind. The tire tread depth gauge quickly identifies excessive wear and determines if your tires meet basic safety requirements.

Complete a tire tread self-check in 3 seconds. It is suitable for family cars, commuter vehicles, and work vehicles. This compact, portable tire tread depth gauge easily fits in glove compartments, backpacks, and tool kits.

Its stainless steel probes and ABS plastic body are rust-resistant and durable. The stainless steel clip secures the tire tread depth gauge to work pants, jackets, or backpacks for quick pre-trip checks, routine garage inspections, and roadside emergencies.

This tire tread depth gauge is a practical gift for customers and is commonly used by car dealerships, repair shops, and insurance companies. It is simple, durable, and genuinely useful.

Green Zone (6/32"–32/32") Safe Range

New tires typically have a tread depth between 10/32" and 12/32".

Winter tires should maintain a tread depth of at least 6/32" to ensure effective traction on snow and ice.

Yellow Zone (3/32"–6/32") Warning Range

Braking distance increases significantly in wet conditions, so replacement is recommended.

If the tread depth is 4/32" or less, the risk of slipping on wet surfaces increases sharply.

At 50 mph on wet roads, tires with 2/32" of tread travel nearly 50 feet farther than tires with 4/32".

Red Zone (0–3/32") Danger Range

When the tread depth falls below the federal legal minimum of 2/32", the tires are considered unsafe and must be replaced immediately.

The vehicle will fail inspection in states with annual vehicle inspections, and police nationwide may impound the vehicle or issue citations.

In the event of an accident, insurance companies may deny or reduce coverage due to "negligent maintenance," especially in single-vehicle accidents.

Easy and Quick to Check

Steadily place the base of the tire tread depth gauge on both sides of the main groove. Press the probe vertically against the bottom of the groove to take a precise measurement. Do not rely solely on color zones for judgment.Measure one main groove on the inner and outer sides of the tire, as well as the center. Use the lowest value as the tread depth for that tire.If the difference between any two measurements exceeds 2/32", it may indicate misalignment, suspension issues, or abnormal tire pressure. Seek immediate inspection.

Tread Depth of ≤ 4/32"

AAA recommends replacement based on actual measurements. At this depth, the ability to disperse water decreases significantly. This increases the braking distance in wet conditions by over 20% and substantially raises the risk in rainy or snowy regions.

Tread Depth of ≤ 2/32"

According to the NHTSA, this is the legal wear limit at which the tread wear indicator becomes flush with the tread surface. Immediate replacement is mandatory. Continued use violates traffic regulations and greatly increases the risk of hydroplaning, blowouts, or loss of control.

Applicable Tires

Standard tires for passenger cars, SUVs, pickup trucks, light commercial vehicles, and trucks. Tires must be structurally sound with primary tread grooves.

Non-Applicable Tires

Agricultural/construction machinery tires, solid tires, bald tires, temporary spare tires, and tires with bulges, cuts, severe aging, or irregular tread patterns.

Application Scenarios

Owner self-inspection | repair shop services | annual inspections and enforcement checks | used vehicle appraisal | commercial fleet management

- The tire tread depth gauge only measures tread depth. It cannot detect rubber aging or internal structural damage.

- Even if the depth meets standards, tires that are over 6 years old or have structural defects must be replaced.

The NHTSA and AAA Recommend Checking It Monthly or Every 5,000–7,500 Miles

Increase the frequency of inspections under the following conditions:

Before the rainy or winter seasons, as adequate tread is crucial for wet, snowy, or icy surfaces.Before extended road trips or frequent highway useWhen the tread depth approaches 4/32", which is the recommended safety replacement threshold by the AAA.If you notice uneven tire wear, your vehicle pulling to one side, vibration in the steering wheel, or increased braking distance.
