Why Does the Same Vehicle Have Different Tire Sizes?

It is common to see several tire sizes listed for the same vehicle model. This can be confusing for customers and even for newer employees at a tire shop.

Different tire sizes can be used because of differences in trim level, model year, engine configuration, factory wheel packages, or optional equipment.

For example, one version of an SUV may leave the factory with 17-inch wheels, while a higher trim level may come with 19- or 20-inch wheels. The recommended tire size changes with the wheel size.

This is why tire shops should not select a tire based only on the vehicle's make and model. Always confirm the vehicle year, trim, current tire size, and manufacturer specifications.

The same principle applies when customers are purchasing a complete tire and wheel package. The tire and wheel need to work together properly for the vehicle.

Before placing an order, shops can review the UAD Tire Inventory and UAD Wheel Inventory after confirming the correct fitment.

For Ontario shops, having access to reliable Wholesale Tires from UAD can make sourcing different applications easier.
