Re: Bridgestone EP422 tires swapped for Michelin Primacy MXV4s.

First I have to say I am an advocate for all four matched tires, it avoids all this. Having said that when I put the snows or summers on I put the better tires up front (maybe .5 mil better tread). While it is true that with a better griping tire up front you are more likely to over-steer that is just one component of driving. Straight out braking you will stop faster with better tires up front becasue most of the stopping force is on the front tires not the rears and avoiding a collision by rapid braking is the most common practice to avoid accidents in the first place. Also being front wheel drive, having better tires up front gets you moving and more importantly not getting stuck in the first place.

Again I don't run mis-matched tires and don't recommend it. I rotate to often, 5k miles and look at the tires when I do, but these are things to consider as well.

Those are all good points I had forgot about, I'm back in the better on front camp but I agree having all tires be similar is the best of options.

for safety better tires always for rear.


very informative which means we need to takeaway the most important statement

"If ONLY replacing two tires, put the new ones on the rear"

The ideology of rotating tires front to rear on a regular basis still stands. for intervals, I recommend no more than every 5,000 miles. I blogged about doing it at a 10,000 mile interval and that was a mistake. no more than every 5,000 miles!

I used to rotate every 10,000 miles on regulars (before leaf) now I do that ever 5000 miles. This also forces me to look over everything else with the tires and related parts as well. And since we have snows rotating them isn't a big deal, just pop a snow tire on the first spot and rotate until the snow is back off. I rotate all the cars at 5,000 now and they do wear so much more even, although I am not sure if I would see an alignment problem like I used to not rotating them as often :)
