Unmatched tires
 

The service department made a note on my invoice that stated my tires were not matching. Is it a big deal to have different brands of tires on at once? I always changed my tires in pairs so the fronts would always match and the backs would always match, but after a recent blowout I had a tire put on that was a different brand than the other. I'm just surprised it was noted on my service order. Is that something I should be concerned with?

I think the service department is just noting what was found , also could be covering themselves for any liability for whatever reason.

Sometimes I've gotten invoices that say the weirdest stuff as well, but I'd rather have more things noted that I may have noticed.

I think it can be an issue if you are running two totally diff. tires on the same axle- like a decent Nitto vs. a top of the line Michelin..they just wear different and ride diff...for the most part we dont feel it since we arent race car drivers, but I prefer to at least match the fronts or rears...

well my front tires don't match the rears, but i prefer them matching, my mechanic says it better to have them all the same type but i don't know why... i never had different tires types on the same axle though..

In theory, mismatched tires can upset the handling characteristics of the car. This is especially true in the rain. One tread pattern may be better and have substantially more grip than another. Unless the car is driven at it’s limits, you may never notice the difference.
