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.
