Find all compatible tire sizes when upgrading to +1, +2, or +3 inch larger rims. Maintains overall diameter within ±3% for accurate speedometer readings.
Enter your current tire size to find all compatible sizes for +1, +2, and +3 inch rim upgrades. Compatible sizes maintain overall diameter within ±3% of your original tire.
Plus sizing keeps the overall tire diameter nearly the same while using a larger rim and lower-profile tire. This improves handling and appearance.
The speedometer error column shows how much your speedometer reading will differ from actual speed with each new size.
