How to Measure ATV Tires


The basic fact to remember while understanding how to measure ATV tires is that all tires come with product specifications of diameter x tire width x wheel size. For example, an ATV tire can measure 25x10x10, which is then understood as 25″ tall x 10″ wide x 10″ wheel diameter.

Though this is the basic concept, buyers must be wary of other factors that determine tire measurements, as prices can increase due to several other factors. It may seem difficult to calculate tire size with increased tread depth, or the additional rim guard, or even the extra ply rating which add to the overall weight of the tire.

Replace existing stock tires with larger tires to increase load-pulling capacity or to generate more power may seem logical, but do they fit on the same wheel? It therefore becomes important to understand how tires offered by manufacturers actually fit on an existing ATV and match other tires already fitted onto it.

Practical aspects of ATV tire measurements

While the three-digit number specified by manufacturers may suffice in order to make an informed purchase decision, offerings may differ based on a combination of other factors. For instance, an ATV tire with specifications of 23x11x10 Front implies it can be mounted on a wheel with 23” height, 11” width, and 10” diameter. Front specifies this tire can be used only as a front tire.

Another variation can be an ATV tire measuring 25×10-12 used with wheel specifications of 12 x 7 – 4/110. This is a perfect match with a 12-inch tire mounted on a wheel with a 12-inch diameter. More precisely, this would be a tire with a height of 25” and width of 10” to be mounted on a wheel measuring 12” in diameter, 7” in width from bead to bead, and which has four wheel bolt holes spaced at a distance of 110 mm from each other, measured from the center of one bolt hole to the center of the other.

How tall can a replacement ATV tire be?

ATV tires are designed to fit wheels that are centered without offset, so replacement tires can vary a bit. With the latest enhancements introduced by manufacturers, ATV owners can be a bit more demanding and insist on larger tires for better traction and more power.

A pertinent question often asked is, “How tall can a replacement ATV tire be?” Knowing how to measure ATV tires here may help users avoid mistakes leading to nullified warranties.

There may also be other factors like stress on suspension components, change in the center of gravity, and concentration of power at the lower end of the wheel. However, the good news is some adjustment can be made to accommodate buyer interest in more powerful tires.

Considering an engine displacement of 450 cc, an existing tire with a height of 28” can safely increase to 29” as replacement. For engines with more than 450 cc capacity, 2” can be added to the overall height. Other specifications like tread width, extra-high lugs, and siped treads may help in sustaining optimal tire life even with the additional height.

How wide can an ATV tire be?

With manufacturers successfully crossing the barrier of trying to sell off-road ATV tires as all-terrain tires, it’s interesting to understand how they sustain impressive designs that improve ride quality without compromising on features like comfort and ground clearance. A major factor is the ability to increase tire width to even 12 inches with a maximum of 11 inches for a front tire.

  • Better steering control

By adding extra-deep lugs focused on creating contact at the center tread, innovators have improved about mud-cleanout capacity. This can create a positive effect on the wider tire which then gets more traction in muddy and snowy conditions.

The same tire also avoids going off track on hard surfaces riding on these extra-deep lugs. Designers take steering control into consideration, ensuring riders encounter less vibrations and have adequate steering power to maneuver around bends.

  • Using wheel spacers to accommodate more tire width

The fact that a larger tire can be fitted on a slightly smaller wheel should please sports enthusiasts looking to replace existing tires with larger replacements. Care should be taken to understand maximum spacer size available for the existing wheel, and if an exact match is found, the extra inch or two on a powerful ATV may add to its aggressive look and feel.


Knowing how to measure ATV tires may help buyers avoid costly mistakes, especially when making an OEM purchase.
