Carried my wheels for tires to be changed on Friday they mounted the rear correctly and the front is mounted backwards, the dual disc forward rotation is opposite from the wheel forward rotation. Rode it just a few miles before I noticed it, getting ready to pull wheel off to have remounted correctly. Assembly went fine even though discs backward. No adverse effects other than small brake squeal which was not present before. What problems could arise from improper disc rotation? Front brakes seem fine so far.......

 

I'm not a mechanical genius (or any other kind of genius) but I dont think you'll have any problems since you immediately corrected the problem.

 

Something you might want to look into is that there are some bikes where the rotors (L&R) are supposed to be switched or the tire is supposed to be mounted with the arrow facing the wrong direction.
I know it doesn't make any sense. Seems the engineers found out they could fix problems by mounting parts backwards.

 

On the 07s (maybe others) they have the L and R marking on the disd backwards from the factory. The L is on the R side, the R is on the L side. They did that to minimize disc brake noise they had complaints about.

You need the tire rotation to be correct with the valve stem pointing toward you for easy access when the bike is on the center stand. This puts the L&R markers on the wrong side, but that is how it is supposed to be, and why some inexperienced tire installers make that mistake.

The issue it cause on my bike was a very small vibration at time around 60mph. Although the wheel goes on, it DOES matter. Make sure it's right.

PS we have almost the exact same bikes if your is a black cherry 07.

 

Yeah I made sure that the tire rotation was correct but in doing so the rotors were on the opposite sides than they should have been
(in other words right on right, left on left which should be opposite left rotor on right ...ect. ) I guess it is best to check the manual even on a job as simple as changing tires.....Now just have to wait til Tuesday cause shop is closed on Monday.....Wheel and tire off now.

 

Maybe I don't understand fully but if you have the wheel off why not just swap the rotors and call it a day?
Thats exactly what I had to do when the dealer put a new tire on my 07 Rim. He mounted the tire so left was left and right was right.
I Just swapped the rotors from left to right...again and was all good.

Could not reversing the rotation of the wheel bearings after they have 'seated' cause bearing failure by running the wheel in opposite direction? And also shouldn't tire been mounted right in first place?

 

You would be changing the load on the bearings, but I couldnt say if that would make them prone to fail. Somehow I doubt that.
I always understood the rotation direction on the tires was because the grooves in the tire are made to displace water so if you have them backwards you may possibly hydroplane instead of displacing water.

 

You've got it Steve..

No you could also just take the rotors off the wheel as another poster metnioned and reverse them, either way might work.. but you want L on the Right side and R on the Left side.

 

Guess my main concern was wheel bearings and possible failure...?
