FAQs:

• What is the difference between 12.50 and 13.50 width? 

  The 13.50 is one inch wider, providing a more aggressive look and better floatation in soft terrain, but it is more likely to rub on suspension components and usually requires wider aftermarket wheels.

• Is this tire "Load Range E"?

   Yes, the LT designation stands for Light Truck, and in this size, it typically carries an E load rating, supporting over 3,700 lbs per tire at 65 PSI.

• Will it fit a 20x9 wheel? 

  Yes, a 20x9 is the minimum recommended width, though many enthusiasts prefer a 20x10 or 20x12 to properly square off the sidewall of a 13.50-wide tire.
