Changing Rim Size

…differences in rim width. The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10". For example: a tire in the P205/60R15 size is measured on a 6.0" wide wheel and this size tire has an approved rim width range…

…and grows from there. Plus Sizing supports the premise that it's important to maintain the same overall tire diameter whenever changing tires and wheel sizes to ensure sufficient ground clearance, appropriate driveline gearing and accurate speedometer readings. Large changes in overall tire diameter…

…their "shoe size," tires have a measuring rim width from which the tire’s specs are taken. While most measurements in modern tires stay relatively consistent as the rim width changes, section width (the distance across the widest part of the tire) is one that is affected by the change, albeit…

…math and some basic tire sizing knowledge. The example below demonstrates the wheel to tire ratio change and how the overall diameter, and therefore speedometer, for all intents and purposes stays the same. The example starts with a 225/45R17, and each step (or minus size) down in wheel diameter…

…at the same ambient temperatures. Since tire pressures change about 1 psi for every 10 Fahrenheit change in ambient temperature, the tire pressure measured in the relatively moderate climate typically experienced at sea level will change when exposed to the colder temperatures associated with…

The rule of thumb is for every 10 Fahrenheit change in air temperature, tire pressures will change about 2% (up with higher temperatures and down with lower).…
