Can changing tire sizes confuse my vehicles on-board computers?
It can if you substantially change the overall diameter of your tires. Maintaining the original, specified diameters as closely as possible ensures that your on-board computers will function properly and thereby effectively manage such systems as your anti-lock braking system, traction control, fuel management system, electronically controlled automatic transmission and electronic handling stability system. Changing tire diameters sends erroneous readings to the computers. These systems won’t fail, but they will be impacted to varying degrees. If you have any questions about this potentially troublesome issue, contact your tire dealer.
