    Can someone please tell me what would cause this scratched/etched/pitted on 5 year old wheels with such low mileage?? Is that a flaw in the aluminum or just our regular road/weather conditions? Just curious. Thanks again. :blush:

    Discount tire will give you free lifetime rotation and will even air your tires up periodically for free. The tire mileage you got is normal for oem Michelins. Your wheels are probably ok. The pitting may be from salt used on some roadways in winter. It's just cosmetic. Hope this helps.

    Rims aren't designed to touch the road surface and if they do, the metal will be abraided.

    So if you operate a tire without inflation pressure, it is possible for the rim flange - the part that makes the rim larger in diameter than the hole in the tire - to come into contact with the road surface. Or worse!!!! - the tire could be dislodged from the rim and then the entire weight of the vehicle is now carried by the rim flange.

    You see, it is the inflation pressure that holds the tire out against the rim and without that pressure, it doesn't take much force to "debead" a tire.

    That's one reason why you should never operate a vehicle with a flat tire. Another is that vehicles don't behave predictably with an odd tire - and a flat would qualify as "odd". A different tire would, too!

    On a side note all this talk about "Don't operate your vehicle with a flat tire" IF you are in a spot where it would be dangerous to get out of your car, ride the rim to a safe place before changing it. I've heard way too many stories where someone got killed because they were changing a tire on a tiny shoulder on a busy expressway.

    To reinforce the danger point:
    On I-75 there was a 2-mile strip of 2 lanes with concrete temp barriers on each side-no berm. A backup occured one afternoon and when I got through it there was a man in the right hand lane changing a rear tire on a smaller car which is light in the rear to begin with. Drive it to the end of the work area!

    Back in 2005 Repair Rim Seal was done on 3 of the 4 tires.

    All of this sounds fairly wierd. Why did 3 of your tires need Repair Rim Seal?

    Going to a "good" tire shop is a good idea. Of course "some" of them can be pretty aggressive in selling stuff, esp. with a customer who's not sure what they need.

    Costco is really good, & I think you get a free lifetime hazard warranty. But they may not really diagnose any problems. The installers should notice if there's anything wrong with your wheels tho.

    Finally, calling the tire rack for advice couldn't hurt. They may have cheap steel wheels in stock too, if you wanted that.

    BTW, how worn are the tires you have now? And how much air do you put in your tires? Are you sure your tire gauge is accurate? You can get a good gauge for $10 from amazon & learn to check them yourself.

    Thanks for the feedback.
    On closer inspection of my dad's Ford Focus, I found that the front left tire was installed at the wrong size -it should be P195/60/R15, the size installed is a P195/65/15. I think this happened when my dad took the vehicle into a Ford Dealer for repair work a couple months ago, after a bad weather induced accident.

    Is this something to be concerned about? Is the 60/65 a dimension of sidewall thickness? I called teh Ford dealer that did the repair work, but unfortunately they are out of businesses. I have noticed that driving the vehicle, it requires more attention to keep it going straight on certain highways, particularly at higher speeds. Also, I feel a sense of instability riding in the back seat (kind of like fishtailing, but not to that extreme) but am not sure if it is due to the left front tire being large, or the rear tires being ready to be replaced.

    Any suggestions will be helpful.

    Thank you.

    You should have the same size tires on all 4 wheels if possible and at the least the same size on each axle.

    The 60 is the ratio of the width to height. So if you have a 195 60 on one side and 195 65 on the other the side with the 65 will have a larger radius than the other side, not a real good thing for stability, tire wear and other reasons. I'd get another 195 65 or 195 60 to match the other side.

    And tires that are mismatched in diameter, as these are, should DEFINITELY not be on the front, or drive axle, of your car since they will stress the differential. At a minimum, move that oddball tire to the rear.

    BTW, the new safety rule is that your WORST tires should be on your drive axle, not your best. This reverses decades of conventional wisdom, but Michelin ran extensive tests and found out that it's much easier to spin out when your best tires are on the drive axle (since you have front wheel drive, the drive axle is the front of the car).

    Interesting, do you have any links on this, I'd love to read up on it as I'm one to put the best tires in the front (steering and braking).

    Your best tires should always be on the rear, regardless of FWD or RWD... This is what gives you the best lateral grip, assuming acceleration isn't being applied....

    (in other words, around a curve at constant speed).

    Also Tire Rack, both of them have information about proper mounting when you only buy two new tires. Tire Rack might have a link to the Michelin study.

    What kyfdx makes sense, but I guess we'll all have to double check now.

    Since I always buy full sets of tires, in practice this issue has never come up for me.
  • paisanpaisan Posts: 21,181
    Ditto on that, I always buy 4 at a time.

    If dad's car has ABS it might be fooled by different circumferences.
    195/60R15 and 195/65R15 are close and if it was an emergency I would use it as replacement (like in the middle of the desert) and put it on rear (as Focus is FWD).
    60 or 65 is the sidewall height as the percentage of tire width.

    How many miles on old tires? Maybe it is time to replace all 4?

    PS Somehow I am not surprised the dealer is out of business.

    I happen to like the Goodyear TripleTreds I purchased for my Mazda 6 sedan. Not only are they great tires, but they look cool too!
  • blufz1blufz1 Posts: 2,045
    Did you notice a loss of mpg on the triples?
  • smokey75smokey75 Posts: 434
    I have the Tripletread Fortera's & have not noticed a loss of MPG. I came from Michelin Cross Terrain
  • blufz1blufz1 Posts: 2,045
    Thanks for the info. I replaced my oem Michelins w/ comfort treads and lost 1 mpg. Very smooth,comfortable,mid priced tire w/ 80k warranty, tho. Thanks again.
