Shopping for used car- are "mixed" tires dangerous?

[Jimmypoo]

Like mixed marriages, the problem tends to be with the inlaws.

So avoid throwing parties where the Michelins and the Kumhos will have to attend.

And God forbid there is a child by Hankook mixed in! The horror!

I dug a trench for the tractor tire so now all the wheels reach the road, more or less.

Cheers!
