Does changing tires include the rims?

[Ramos]

Generally, changing tires does not require replacing the rims. However, if you want to increase the tire width or reduce the tire thickness to enhance road grip while driving, it may be necessary to widen or enlarge the rims. Rim size is a crucial parameter determining whether a tire can fit onto the rim. For example, a 16-inch rim cannot accommodate a 15-inch tire or a 17-inch rim; it can only fit a 16-inch tire. If you want to install smaller or larger tires, you must also replace the rims. Installing improperly sized tires on rims can easily cause the tire to detach during aggressive driving, which is highly dangerous. To ensure the tire is securely mounted on the rim, the tire width must match the rim size (i.e., the J value). Exceeding or falling short of this size can lead to the tire separating from the rim, posing safety risks. Typically, without changing the rims, the tire width can be increased (or decreased) by 1-2 levels. For instance, an original 215-width tire can be replaced with a 220 or maximum 225-width tire. However, upgrading to a 235-width tire may pose safety hazards, especially during sudden braking, as it increases the risk of the tire dislodging. Similarly, a tire with a 60-height profile can be replaced with a 65-height one, but the suspension travel should be considered to avoid potential rubbing against the fender. Extra caution is needed when simultaneously increasing the tire width. Definitions of tires and rims: The rim is the rotating part of the wheel that connects the tire's inner contour to the hub via spokes, serving as the metal component that supports the tire and mounts onto the axle. It is also referred to as the wheel rim, steel rim, or hub. The tire is a circular, elastic rubber product mounted on various vehicles or machinery, typically installed on metal rims. It supports the vehicle's weight, absorbs external shocks, ensures contact with the road, and maintains driving performance. After installing new tires, it is advisable to perform a wheel balance check since the old rims may have balancing weights attached. This helps prevent abnormal tire wear and steering misalignment. Daily tire maintenance tips: Regularly inspect the tire surface for cracks, deformations, or other defects. As tires wear down, the tread grooves gradually become shallower. Worn-out treads lose their ability to drain water and provide traction, significantly reducing the vehicle's performance. Small cracks can also become potential hazards for blowouts at high speeds. Additionally, promptly remove any stones lodged in the tread grooves. Park on level ground whenever possible. Avoid parking on surfaces with thick, sharp, or pointed stones. Keep the vehicle away from or in contact with petroleum products, acids, or other materials that can degrade rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Avoid splashing water to cool overheated tires. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, park to let the tires cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear caused by dragging the tires against the road surface.
