This feature is vital for navigating off-road conditions where traction can be unpredictable. In heavy-duty applications, such as hauling loads over rugged landscapes, having a dependable 4 wheel drive system enables these trucks to maintain stability and control. This improved handling allows drivers to traverse mud, snow, gravel, and steep inclines with confidence.

The second number, 65, represents the aspect ratio of the tire. This ratio is a percentage that describes the height of the tire's sidewall relative to its width. Specifically, the sidewall height is 65% of the tread width. For the 285/65R20 tire, the sidewall height would be approximately 185mm (calculated as 285mm x 0.65). A higher aspect ratio usually indicates a taller sidewall, which can improve ride comfort and absorb shocks from uneven terrain. However, it may also lead to less precise handling compared to tires with a lower aspect ratio.
