    Well, we can't help when people file their reviews, but I know that for me, a review by someone who has driven their car for a good length of time carries a lot more weight than one by someone who is barely off the dealer's lot.

    Do you own a 3-Series? Have you filed your review?

    I think you will find that the National Highway and Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) are only interested in things related to safety - like tires failing. Noise, vibration and wear don't qualify.

    I would suggest energies be channeled into areas that might have a chance of reaching sympathetic ears - like the Federal Trade Commission.

    Yes I have a 2006 330I. No i haven't filed a review. Ill do so in the near future.

    PS: I had a 2002, gave to my son. It has 65K miles and except for Brakes and Rotors it has had no mechanical/service problems. Tires were replaced at about 40K Mls.

    Good, I'll look forward to seeing it! :-)

    Have been following this forum since purchase of my 2006 325xi non-SP in April 2006. Had El 42 GFT on my 2004 Acura TL. They were noisy with mediocre handling. Switched to Bridgestone Turanza LH and things improved immensely. Currently have 15,000 plus miles on EL 42 RFTs. Same problems as Acura. However, I ignored BMW's recommendation not to rotate tires (sounded stupid to me) and rotated tires every 5,000 miles. Unfortunately, the tires are wearing evenly and well. Will easily get 30,000 plus from the tires. Not sure yet if I will stay with RFTs when these do finally wear out.
  • Guys the solution is to rotate tires just as we have done in the past. DO NOT follow BMWs recommendation not to rotate. Rotate by moving the rear tires
    straight forward - no not cross over. Take the fronts and cross them on the way back. Right fron to left rear and left front to right rear. Do it every 5,000. This will result in even wear and cause the cupping to cancell out when you move the old fronts forward on the second rotation and all subsequent. The cupping is on the outside front tires and it gets worse as time goes on.I got my EL42s replaced by Firestone by dealing directly with Firestone National Customer Relations. All it cost me was mounting and balance and road hazard and stems. 4 new tires free! :D
  • Wow, if one were to rotate back tires to fronts, that'd make for a very odd handling car given the rears on 330/335is are wider than the fronts.

    "Guys the solution is to rotate tires just as we have done in the past."

    Agreed.

    "Rotate by moving the rear tires straight forward - no not cross over. Take the fronts and cross them on the way back. Right front to left rear and left front to right rear."

    Not advised. While I don't know about the EL42s, many tires these days are directional and crossing over would cause directional tires to rotate backwards. Even when tires aren't directional, I don't believe that I've ever read a manufacturers recommendation to cross radial tires. Simply put, rotate tires front to back, keeping them on the same side, is the proper method of rotating radials.

    Caution: The above comments are applicable to cars that have the same sized tires both front and rear, unlike all "i" model E90s with the SP. For SP equipped 3-Series cars ("i" models only), your only options are to A) put up with the noise, B) replace the tires early, or C) buy wheels and tires that are symmetrical for both front and back.

    I agree with Shipo. Radial tires should only be rotated front to back on same side. Separation of rubber from belts is a strong possibility (personal experience) reversing rotation direction after tires have been driven awhile.

    HELP! I am scheduled for service in a week and I had planned to rotate my Conti RFT's that are beginning to exhibit a bit of noise after approximately 9,000 miles. I replaced my Bridgestones with the Conti's. BMW does not recommend rotating so how can I ask them what the proper method of rotation is?? When I had Bridgestones they were rotated by a Firestone dealer, rear to front and crisscrossed front to rear. Now I read differing opinions.

    Help me out. Who's right and who's wrong???

    I've been rotating radial tires front to rear for over 30 years, per the recommendation of most manufacturers. Crisscrossing really won't buy you much if any benefit and could be a huge detriment if your tires are directionally sensitive (you'll know if there is a rotational arrow on the side wall).

    Basically, relax, rotate front to rear, same side and keep on truckin'. ;-)

    Shipo is right - do not cross fronts when moving to rear - go straight back on same side. If you have a floor jack, you can lift one side of the car so the process takes minutes.

    Again, make sure the ires are the same dimensions, 225/45 17 on all 4 corners, for example. If not, forget it.

    Grew up in the tire business. Crossing tires pretty much ended when pre-radial belted tires came out. The belts would shift back a tad while driving at high speeds. Reversing direction after this seating would ofttimes seperate the rubber from the belt causing bubbles in the tire. Same problem with the belts in radial tires.

    Shipo,kirkr, circlew.............
    Thanks for the advice. It's front to rear and rear to front with no crossover.

    Kirkr,

    You should have stayed in the tire business a little longer as the current recommendation for rotation includes "crossing". To verify this look at any tire manufacturer's web site.

    "...the current recommendation for rotation includes "crossing"."

    By whom? Under what circumstances? Please provide references or links.

    Best Regards,

    "You should have stayed in the tire business a little longer as the current recommendation for rotation includes "crossing"."

    Was my Dad's business. Glad not to have followed his footsteps. However, in 1995 had the separation problem by heeding advice that radials had "improved" and crossing was OK. It is possible that they have "improved" again. But I have always gotten excellent wear rotating "front to back same side" without "crossing". Like Shippo, been rotating tires for several decades.
  • This rotation was what the company owned Firestone dealership recommended for their tires for rear wheel and four wheel drive cars. ie. move the rear tires forward with no crossover. But the front tires should be crossed. For front wheel drive it is reversed. I. E. The rears are crossed when moving forward. It is in print in a tire maintenance and ownership guide handout they gave me as well as verbally from the manager.

    It is also useful to note that tires lose about 1 PSI a month plus they drop 1 PSI for each 10 degrees F the temperature drops. Under inflated tires are dangerous. They overheat plus they wear out faster, adversely affect handling, and decrease fuel consumption.

    So keep them pumped up and rotate them and I believe they will last longer and run smoother. :)

    From Tirerack:

    Four (4) Tire Rotation

    On front wheel drive cars, rotate the tires in a forward cross pattern, or the alternative X pattern.

    On rear wheel or four wheel drive vehicles, rotate the tires in a rearward cross pattern.

    Diagrams available on the following web site.

    "30k miles is a crazy amount for a BMW."

    Shipo, I agree with you that this is not necessarily the case. My 97 528 has 155K on the clock and is on its FOURTH set of Michelin MXV Energy tires (including the originals). I have replaced the tires each time after approximately 45K of wear, with probably another 10K left on them. I don't drive like crazy, but don't baby it either. Also, these tires are consistently quiet. I tried some Dunlops when I replaced tires at around 90K but did not like the noise and the "slippery" handling, so took the car back in and had the MXVs put on again. Each car is different of course, but if you find a type of tire that works well on your car, stick to it. RFTs seem to have a ways to go before they solve the wear and noise problems.
