My front right is pretty beat up due to about 20 laps around the track without overinflating. It looks worse than it probably really is when compared to the other tires on the car but I definitely should rotate it before returning to the track. <p>The Rossos are non-directional if I recall. Is there any problem with doing a criss cross rotation pattern so I can move the most beat up tire to the wheel that receives the least abuse at the track (rear left). I could then do a third rotation that moves the rear left to the front left and the worn front left to the rear. Then one last criss-cross rotation. This will always keep the same pair of tires on the same axle which is the main concern for an AWD car. I can't see any reason that swapping sides in a criss cross rotation would cause any problems when using non-directional tires.<p>Iluminate me if necessary.<br>

Re: Tire Rotation (jazee)

NEVER, I repeat NEVER cross rotate.<br>Front to back only

Re: Tire Rotation (Mash)

I'll try to come up with the proper explanation tomorrow without winging it tonight,

Re: Tire Rotation (MagoonR)

I think the explanation has something to do with the belts inside the tire carcass taking a "set" . . . might get a rough ride or unacceptable handling attributes if cross-rotated.<p>A dealer recently recommended that I do just that with one of my work trucks, though . . . an employee took it for a 450-mile round-trip drive to a jobsite near NYC . . . came back complaining that the front-end was squirrely & noisy. Turns out he left the 4x4 hubs in the "locked" position, even though the transfer case was in RWD. Badly cupped both front tires, & cross-rotation was recommended to even up the tire wear a bit.<p>Maybe this is acceptable for a light-truck tire but not a high-performance car tire?<p>Our OEM Pirellis aren't directional, btw . . .<p> - Mark

Re: Tire Rotation (geoguy)

I cross-rotate my tires as long as they're not directional. The Rosso's are not directional.

I think if you rotate often, like every 3,000 miles, I don't see how the tires could get enough wear in any one position on the car that doing a cross rotation would cause any issues. <p>I pulled my Rossos off after only 2,000 miles on the car and put some P-Zero Nero all seasons on and kept the Rossos for summer/track usage. So I've got a set of Rossos with like 3,000 miles on them that one tire the tread is chunked up a bit from the track. I'd like to get another 3 track sessions before tossing the tires and the only way to do that would be to alternate between a cross rotate and a front to back rotate so that every tire gets to take it's turn at the front right position. At the end of the summer, I throw the Neros back on. Those of course I would not cross rotate. I'm very easy on those tires.<p>So I don't care if cross rotating causes abnormal wear on the Rossos. They are only going to get another 3,000 miles or so and a couple track sessions before I throw them away with about a total of 6-8K miles on them.<br>

Tirerack disagrees and has some pretty interesting reasons. They say use front-to-back only if the tires are directional. AWD cars with non-directional tires have two choices, X pattern or "rearward cross" (rears to same side front, fronts to opposite-side rear).<p><IMG SRC="http://www.tirerack.com/images/tires/tiretech/rotate5.gif" BORDER="0"><IMG SRC="http://www.tirerack.com/images/tires/tiretech/rotate1.gif" BORDER="0"><p><A HREF="http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=43&currentpage=38" TARGET="_blank">http://www.tirerack.com/tires/...ge=38</A><p>Tom.

The Tire Rack arcticle does not address AWD cars. Just FWD and RWD, although as far as tire wear, the R is essentially a FWD car (90% of torque to the front 90% of the time practically.)<p>Still, my particular reason for cross rotating is due to non-typical use at the track causing extreme wear on one tire. The beat up tire is going to get the least amount of abuse in the rear left position - effectively giving it a 'rest.'<p>
