"Using "matched" tires means all four tires are the same brand, design and tread depth. Mixing tire brands, tread designs and tread depths may cause components in the vehicle's driveline to fail." This necessitates that four-wheel drive and all-wheel drive vehicles use tires that are very closely matched.

Functionally, mismatched tires will wear out at different rates.Can tires affect transmission?

If you are running an automotive transmission this can cause some serious strain depending on the current gear ratio if you choose not to regear your system.How many years do tires last?

There can be exceptions, though.
