pothole. I drive my car pretty conservatively and with mismatched rubber front to rear and it has never been an issue. I do use similar tires front to back in that they are all summer performance and not all weather tires. The car until recently has been my DD so tire wear and longevity was one of my major concerns. IMO if you are driving the car to the point that mismatched rubber is frequently becoming a driving hazard (assuming the tire designs are similar) then you probably need to do that kind of driving on the track. I have been able to get about 35k miles out of the last set of fronts I had on the car and of course the rears are wearing quite a bit faster. When I go to replace tires, sometimes the tires I would be trying to match to the fronts or vice versa are out of stock or no longer in production so instead of scrapping the good tires still on the car and starting over with four new, I find whatever is comparable and still fits the budget and durability requirements.
