Directional or non-directional refers to the tread pattern and how it is made to push water away. The advantage of non-directional is you can swap them side to side and run them in the other direction. Avoids having to dismount and remount the tires on the rims.And why do you want non-directional ?
KEEP IN MIND THAT NON-DIRECTIONAL TIRES DO NOT DISPERSE WATER AS WELL AS DIRECTIONAL TIRES DO... also keep in mind that your SPYD3R does not weigh as much as an automobile... those 2 combinations can cause you to think twice when riding on wet surfaces... you would hydroplane more easily on the non-directionals (not to say you WILL, but could)... other than that, you should be ok....

Is that a proven fact or mostly marketing hype?KEEP IN MIND THAT NON-DIRECTIONAL TIRES DO NOT DISPERSE WATER AS WELL AS DIRECTIONAL TIRES DO...
Thanks all, it would be nice to be able to rotate the tires.
I vote for ...HYPE ... if it wasn't Hype ... they would be the ONLY type of tires Sold ....that's the easy to understand version .... Mike :thumbup:Is that a proven fact or mostly marketing hype?
Sorry, but your Michelin engineer friend is mistaken. Here's a quote from tiresafety.com, a website of Bridgestone. http://www.tiresafety.com/maint/maint_content.asp In the very early days of radial tires the general advice was not to reverse the rotation but that hasn't been the case for years.DO NOT ROTATE YOUR TIRES BY WAY OF TAKING THE TIRE/WHEEL ASSEMBLY OFF, AND MOVING IT TO THE OPPOSITE SIDES...
correct rotation of non-directional tires would be to mark the outside wall or each tire, then removing the tires from the rims, and remounting them with the 'mark' on the inside... this would allow you to have the former right side tire on the left, and vise-versa for the opposite side... now your tires would hit the road and spin in the same direction as they did originally...
tires take a 'set' in a few hundred miles, and if you do the above, you risk your tires developing serious issues... NO, i am not a tire guy, but we have a Michelin engineer that rides with us, and he's informed us of many issues with tires...

Modified Cross Rotation
The "Modified Cross Pattern" provides the best results and can be performed on any Front or Rear Wheel Drive vehicle equipped with 4 non-directional tires. (directional tires must be rotated front to rear only.)NOTE:
* Free rolling axle tires are crossed and installed to the drive axle, while the drive axle tires are brought straight to the free rolling axle (without crossing).
* Make sure you maintain vehicle manufacturers inflation recommendations after rotating tires.
* Directional treads are designed to perform in the direction denoted on the tire sidewall only. They must always be rotated front to rear - despite the type of vehicle they are installed on - so the direction of the revolution does not change.

When
rotating tires with a directional tread pattern, observe the arrows molded
on the sidewall that show the direction in which the tire should rotate.
Care must be taken to maintain the proper rotation direction.
