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.

The primary function of gear oil is to lubricate the moving parts within the transmission, including gears, bearings, and synchronizers. This lubrication reduces friction, which is essential for maintaining operational efficiency and preventing overheating. Excessive friction can lead to premature wear, reducing the lifespan of the transmission and leading to costly repairs. Moreover, gear oil also acts as a hydraulic fluid that enables the proper functioning of the gears during shifting.
