Perlova Posted October 12, 2007 Share Posted October 12, 2007 I just noticed that the BMW dealer mounted my rear tire on the wrong way. The rotaion arrow is on the right side of the tire. It's a Metzler Z6. Been on for about 500 miles. Are there any issues with putting it back on the right way now that its been on the bike? Link to comment
stubble! Posted October 12, 2007 Share Posted October 12, 2007 I can't think of any reason not to switch, especially after so few miles. Inspect it well for abnormal wear. Link to comment
Bob Palin Posted October 12, 2007 Share Posted October 12, 2007 While I don't think there are any issues, if the dealer did it I would be asking for a new one. After all, those first 500 miles are the best miles of a tyre's life. You can send the old one to me, somebody will need it Bob's Tyre Repository Tyrrey, Utah Link to comment
RFW Posted October 12, 2007 Share Posted October 12, 2007 The grooves are optimized in the direction for optimal water elimination. The actual pattern of grooves is in almost all cases opposite for the rear tire, as compared to the front one, when installed with the arrows pointing in the correct rotational direction. The reason for this is that the front tire is optimized for braking forces, whereas the rear one is optimized for acceleration forces. Having said all that, take the bike to the dealer, tell him to smarten up and reinstall the tires PROPERLY, so the rotational arrows are pointing correctly! What do these guys use for brains?! I mean, just how hard is it to interpet the direction an arrow is pointing?? Tell him it must be rebalanced too! Link to comment

Not to insult you but when you rotate the tire does the arrow circle to the front of the bike? You could have an arrow pointing to the rear of the bike when the arrow is on the bottom of the tire but it would point to the front of the bike when the tire was rotated so the arrow was at the top.

Perlova Posted October 12, 2007 Author Share Posted October 12, 2007 No...the arrow rotates to the back of the bike....opposite the way that the arrow is pointing. I suppose if I had a reverse, it might work... Link to comment

Unlike a front motorcycle tire a rear motorcycle tire can be used on the front of a bike IF the rotation arrow is reversed.. So the tire was designed to rotate either direction.. Just to be sure you won’t have any future warranty issues you might call or E-Mail Metzler help line.. Twisty Link to comment

dcm3 Posted October 13, 2007 Share Posted October 13, 2007 This exact same thing happened to me a few years ago, except it was a Michelin tire. I too was concerned, so I contact Michelin via email. They told me that I should expect no problem from having had the tire rotating the wrong way for the short time. If you're concerned, I'd suggest emailing Metzler for their advice. Good luck.

David Posted October 13, 2007 Share Posted October 13, 2007 On race tracks with a predominant direction (faster, tire-wearing corners all going the same direction), we'll regularly wear one side of the tire out and then flip it around and run it the opposite direction until that side wears out. Never an issue, though you do lose the tread pattern advantages when displacing water. Link to comment
Ken H. Posted October 14, 2007 Share Posted October 14, 2007 I had a dealer do it to me too. While after some digging I concluded the tyre would probably be fine, I insisted on a new one just on the principle of the deal. Then I bought a tire changer! Link to comment
notacop Posted October 14, 2007 Share Posted October 14, 2007 If it's mounted backwards won't it gain tread and last longer as it's used? Seems like reverse Polish notation but it do have a place in the universe. Link to comment
KDeline Posted October 15, 2007 Share Posted October 15, 2007 I thought the issue was the way the tire ply's are built and the direction they are going, that the tire can come apart. Just something I heard. Link to comment

Just something I heard. Kenneth, most M/C tire manufactures will allow the rear tire to work either direction as most suggest the rotation direction be reversed if a rear tire is used on the front of the motorcycle..

David Posted October 15, 2007 Share Posted October 15, 2007 In addition, the force of braking is at least as strong as the force of power application to the rear. Link to comment
Perlova Posted October 16, 2007 Author Share Posted October 16, 2007 I took the wheel off and returned it to the dealer. They were very apologetic and re-mounted the tire the right way and re-balanced. I'm glad that I noticed it before too many miles went on... Link to comment
KDeline Posted October 16, 2007 Share Posted October 16, 2007 In addition, the force of braking is at least as strong as the force of power application to the rear. Actually that was the issue, braking. The ply's could pull apart with the wrong direction force. Again just something I have heard over the years and a long time ago at that. Link to comment
