ATV FAQs

• How do I determine the ply rating of my ATV tires?
  On the sidewall of your ATV tire you will find star imprints. Each star equals 2-ply. For example: three stars on the sidewall of a tire means the tire is rated at 6-ply.
  
• My ATV came with tires rated at 2-ply. Why would I want to install tires rated at 6-ply?
  If you are riding in conditions that demand a great deal of strength from your tires, using a tire with a higher ply rating is recommended. For example: when riding in rocky conditions, use a higher ply rated tire to reduce the chance of puncture.
  
• I want to purchase Maxxis tires. Can I get them directly from you?
  The best place to go is to your local ATV dealer. Your dealership will be able to help you find the best Maxxis tire to fit your particular application. If the dealer does not have Maxxis tires in stock, he can order from any of the large distributors.

• What air pressure should I run in my ATV tires?
  At Maxxis we always suggest running the air pressure recommended by your vehicle’s manufacturer. The maximum air pressure listed on the sidewall of the tire is not necessarily the pressure you should use.
• How do I tell the size of my Maxxis ATV Tire?
  Most ATV tires are generally sized using the following format: AT25x10-12. The letter "R" may replace the dash to denote radial construction. The first number represents the Overall Diameter (O.D.); the second represents the section width (S.W.); and the third represents the wheel diameter. All measurements are in inches.

  Note that these numbers are approximations and individual tire sizes may vary. For example, a 25x10R12 Maxxis Bighorn has the following specifications: O.D. = 25.4", S.W. = 10" (Of course, the rim diameter is 12".)

• Should I replace my current tires with the same size, or can I use larger tires?
  When replacing tires of different sizes, it is best to check with the vehicle manufacturer or a Maxxis retailer. You will generally be okay with small changes, as with from a 20x10-9 to a 20x11-9. However, it is always best to check with the vehicle manufacturer to ensure proper operation.
• What can cause air loss in my ATV tire?
  There are a few items you should check if you experience air loss in your ATV tire. First, check for punctures, cracks, and impact damage to the sidewall and tread region of the tire. Second, check your valve stem and valve core for leakage. A damaged or aged valve stem and a loose valve core can result in tire air loss.
• Are there any specific care instructions for my new tires?
  Take care while becoming familiar with the new handling characteristics of your replacement tires. While braking, accelerating, and cornering, special care should be taken until you have become accustomed to your new tires.
• What type of maintenance should I perform on my vehicle’s tires?
  The most important maintenance function you can perform on your all-terrain vehicle is a frequent check of tire pressure. Under-inflated tires will result in a variety of problems including premature wear, poor handling, fatigue, or sidewall cracking. It is also a good idea to routinely make visual inspections of your tires. Be sure to check for foreign objects located in the tread surface or sidewall.
• How can I get better mileage out of my ATV tires?
  There are a few key riding habits that can help increase the life of your tires. Avoid fast starts and panic stops. Make sure to always check and maintain your tire air pressure.
