Tire specification 235/65R18 is the tire size code. In 235/65R18, 235 represents the tire width of 235mm, 65 represents the aspect ratio of the tire's height to width as 65%, R indicates that the tire is a radial tire, and 18 means the tire fits an 18-inch wheel rim. The following is relevant information about tires: 1. Wider tires consume more fuel: The wider the tire, the larger the contact area. Under the premise of the same tread pattern and material, wider tires provide better grip and traction when driving straight, but fuel consumption will increase accordingly. 2. Classification of tires by usage: including load-carrying tires, passenger car tires, and mining tires, etc. Load-carrying tires must indicate the ply rating on the sidewall in addition to the size specifications. The ply rating of load-carrying tires does not refer to the actual number of layers but indicates that the tire body made of high-strength material cords has a load performance equivalent to that of a tire body made of cotton cord layers.
