What Is a Tire Load Index?
A tire’s load index is a standardized numerical code stamped on the sidewall that specifies the maximum weight a single tire can safely support when inflated to its maximum allowable air pressure. This rating dictates the structural weight limits for passenger cars, trucks, and SUVs. What Is a Tire Load Index and How Does It […]
What Does XL Mean on a Tire? Extra Load Ratings Explained
XL stands for Extra Load, indicating a reinforced tire designed to carry heavier weights at higher inflation pressures than standard passenger car tires of the exact same physical size.

Are Drag Tires Street Legal? DOT Rules and Road Risks
Some drag tires are street legal in the United States, but a DOT marking alone does not guarantee legal road use everywhere. A DOT-marked drag radial or qualifying cheater tire may be used on public roads when its manufacturer permits highway use and the tire meets federal, state, vehicle, inspection, load, speed, and equipment requirements. […]

What Is Speed Rating on Tires?
A tire speed rating indicates the maximum safe speed a tire can maintain over time under its recommended load capacity and proper inflation pressure. Regulated by standards organizations like the European Tyre and Rim Technical Organisation and the United States Department of Transportation, this letter designation represents rigorous laboratory testing limits rather than a recommended […]
Can You Drive a Car With a Flat Tyre? Safe Limits
No, you should not drive a car with a flat tyre. A standard pneumatic tyre can lose steering control, overheat, destroy its internal casing, and damage the wheel within a short distance. Move only far enough, and slowly enough, to escape immediate danger, then stop on a safe surface and arrange a repair, spare-wheel change, […]
When Should I Replace My Tires?
You must replace your tires immediately when they reach a tread depth of 2/32 of an inch, hit 6 to 10 years of age from the manufacturing date, or show visible structural damage like sidewall bubbles or deep dry rot. While a general mileage rule suggests replacement every 50,000 miles, factors like vehicle weight, climate, […]
