    Where do your good ones go...i know they are realyl supposed to all be equal, but really...whose are? I have heard both, and after riding with my friend today with bald tires in the back going 80 in the rain - not my truck, not me driving, not my idea- I think the good ones should be on the back...thats what I've heard most anyway...even for a front wheel drive car. Anyoen know

    Good on the front. Just call a tire shop and ask them.

    Put your best on the front, they do the steering and 70% of the braking. Ever try to steer a truck with a blown front or rear tire and stop it. I've done both and believe me, a blown back tire isn't any fun but a blown front one is a memory you don't want. Almost had to change my pants afterwards.[​IMG]

    Front no question!
    Ever look at a big rig with re-caps? You won't see em on the front...steering axle should always get the best tires ya got!

    Sorry to be so late on this but I have to disagree.
    This is one of those cases where "logic" doesn't help.

    Best tires should always be on the rear.
    A blowout on the rear is the hardest to control.

    Blowout on the front is the most controllable because you
    have a direct connection to the steering wheels. Even if
    only one is any good and you have a wrestling match on your
    hands, the reaction time between turning the steering wheel
    and moving the front of the vehicle is very short.

    A blowout on the rear has you reacting with the front tires
    to an event happening on the rear of the vehicle. The reaction
    delay makes it harder to control and prone to over-correction.

    I did tires for 10 years with lots of training, no question here.

    Check the details of the Firestone/Explorer fatalities and I think
    you will see the deadliest event was a rear tire failure at high speed.
    Almost always results in a rollover.

    I know this isn't common knowledge and there are
    plenty of people to whom this will be counter-intuitive,
    but it is a fact.

    Blowouts at highway speeds are bad, no matter which
    end gets it, but blowouts on the rear are the worst.

    73 is right and there is more. The good tires on the back help prevent over steer (rear end comming around). Over steer will generaly get you in MUCH more trouble then understeer (where the vehicle just plows and doesn't turn).
    Car and Driver did a Test on a skid pad. They watered down the course to simulate rain. First they tested a car with 50% worn tires and the speed where the car broke traction. Then they put 2 new tires of the same brand on the front. They lost like 9 MPH and the rear end came around every time in a manner that the average driver would have lost control. Moved the new tires to the rear and picked up 4 MPH over the first test and with 4 new tires they picked up 6mph.
    I recently replaced tires on my car. Had to buy 2 at a time. The boys at Costco surprised me by knowing this. Well when I went to get the second pair even though the car only had 2,000 miles on it since the 1st 2 were installed they rotated the tires and put the news on the back again. Nice to see they did their home work and rotated.
    Now if they would just learn the Blue dot is supose to be lined up with the valve stem! Got to get them to spin the tire so I can get rid of most of this big honking weight. Funn the one tire that they got close used the least weights...think that would clue them in.

    It's not my damn planet monkey boy!

    Also a late one, but the good ones go on the back ALWAYS. This is what my cousin tells me. He works for Michelin in the R&D dept. I have to agree with "73Jimmy" on this also.

    maybe i don't have rotating to do...I know blowouts suck in the back. I was driving a minivan on Sat night [​IMG] and the rear tire blew...hard to control.
