New Bohemia, Va | I have my rear tire mounted and I get it home and it is backward according to the tire rotation marks. However, the pattern matches the front tire according to the tire rotation marks on the front tire. So with that, it seems when both tires are mounted correctly, the tread pattern are oppisite to one another, does this make sense?
What would be the harm in running the tire "backwards" on the rear?
I just read on the Harley forum that the treads are oppisite and that is the way it should be. I has to do with the rear being a drive and the front being a push. I have to wait until tuesday to get it corrected.

Rancho Cucamonga, CA | Front tires traction is based on decceleration forces since it does not provide any acceleration of its own. Rears are set on how the tire will grip when accelerating. Theoretically, running a rear tire backwards would give you better traction while braking, but may cause it to fail prematurely since it won't be able to handle the acceleration forces as well (inner construction built directionally for higher acceleration forces then decceleration). Also water channels would be backward. This is a big reason running rear tires on a front wheel is not a good idea. Many run a rear tire on the front backwards to keep the directional forces correct for tire construction, but then the water channels are backwards. Sorry TMI for your situation. |

New Bohemia, Va | not at all ND, never gave it any thought, but it all makes sense. I just can't ride now until wednesday since I'm out of town through Monday and will drop the tire off on Tuesday to get it corrected. |

| Don't change the tires!!!!!!
Leave them the way there are!!!!
If you change them the cords will weaken and the tire will not last very long.
As long as the dearer screwed up go back and see if you can get a new tire or credit. Why not |

Central New York | If you have a REAR motorcycle tire on the REAR, and the arrow is going in the wrong direction, the tire is mounted incorrectly and whoever did it should replace the tire at no cost to you because they voided your tire warranty.
I am sure someone will post that they run tires backwards all the time and never had a warranty problem, maybe so. And maybe you would never have a problem either, but technically, that gives the manufacturer a justifiable out if they choose to exercise it. Why would you want to do that.
That is the same argument I have always had against going darkside. There may never be a problem, but you have enabled an escape clause. Is there anyone that really believes that if something ever happened to them as a result of a mechanical failure while running the darkside, that the lawyers wouldn't use that card against their family? Why would you take the chance? For a few dollars and a few extra miles? |

Indianapolis, IN | The mechanic was apparently "asleep at the wheel"........... sorry, had to. ;-) A good bike mechanic always notes the direction of the old tire in relation to the wheel before removing the old one. A left side drive pulley is more common on motorcycles and an absent minded wrench will sometimes assume left drive. I had this same problem but the wrench decided to check with me before mounting the tire because he forgot to note tire direction before removal. I'd say good thing you caught it, my biggest worry would be traction in wet conditions. The rain groves probably would not work very well with the tire backwards.

Front and Rear Tire Matching
Correct matching of front and rear tires is important for peak performance and handling. Mating a new tire with a worn tire is never a good idea. It is best to follow the Tire Selection guidelines provided by the manufacturers and change out both tires at the same time if possible. A new front tire with a worn rear tire can cause instability.
Also, make sure that the tires are mounted in accordance with the directional arrows. There are two main reasons for directional arrows. The first of these is that some motorcycle tires now have tread patterns that are designed for a specific rotation for optimum performance, particularly on wet roads. Directional arrows indicate the proper directional rotation.
Secondly, running a tire will set up a wear pattern and it might not roll smoothly if reversed. Use the directional arrow to re-fit a tire in its original direction.

New Bohemia, Va | Okay - the world is back on the proper rotation. I have no bad thing about the shop or the guy that did the job, but the first thing he said to me was "I put the new one on the same as the old one." I told him, no way because it caught my eye that something was amiss before I put it on the bike. He says it again, but then I came back with, "I had that one mounted here also."
I do always check the rotation and never has a tire ever been put on backwards. The thing that made this time any different for both of us is we had a hurrican bearing down on us. I was wanting it to be ready to ride today, but all is well, we'll be rolling tomorrow, thankfully.
We do have power back on and a brand new generator that has never been out the box - maybe I'll need it for next time. |

Brighton, TN | Cool, so how did you get him to change it, if it was the same as last time. Well, the angle of the rim spokes should have given him a clue as to which way the tire rolls. |

Indianapolis, IN | Funny you mention the generator still in the box. We were out of power for 10 days several years ago and found out how hard that can be. So this past winter we had a very bad ice storm forecasting that said some may be out of power for a week or more. Needless to say I bought a generator to be prepared, and wouldn't you know, it hasn't been used to this day. But we are prepared when we do need it. ;-) |

And at one time the world was flat... why would anyone want to sail off the edge of the world? |

Baaaa, so funny, thanks for the smile this morning mr. HH.
By the way, the guy at the dealer refuses to touch the darkside, even though there is another mechanic there that will do it for riders. He states that he could not give it an inspection sticker as a certified state inspector because the wording in the law. I've not looked it up myself, but he says that items must be for the application intended for, thus, car tires are for.....

tire rotation - help
