Is It Possible to Put Larger Tires on a Car?

Using larger tires on a car is called "plus sizing" and can improve the handling and aesthetic quality of the vehicle. While most vehicles are amenable to plus sizing, it is important to verify proper tire size before installation.

It is possible to put larger tires on a car or other vehicle. There are two important considerations when plus sizing tires on a car: overall diameter and gear maintenance.

A tire of large outside diameter may rub the fender, which may result in body or tire damage. Further, larger tires may affect gear timing by slowing acceleration. It is important to select a larger tire with the same outside diameter, but a lower profile or smaller sidewall. Owners also have the option to purchase a wider tire to gain a larger tire footprint that may improve handling. Verify appropriate tire heights and widths for the vehicle in question before purchasing.
