I 'am at about 7,000 miles and curious when everyone else does it?
thanks

thanks in advance.

Read your instruction manual, rotating tires is required, to ensure proper tire wear.
The SH-AWD is indeed full-time, but the torque distribution is not constantly 50:50. It is quite a bit of 70:30 Front:back, especially during dry road driving.

sometimes oil indicator comes up every 4000-5000 miles, this is a bit early to rotate tires (but probably convenient to have it done at the same time). I am pretty sure you could rotate tires every other oil change and still be OK.

excerpt from Tire Rack:
The ability of four-wheel drive and all-wheel drive vehicles to divide the engine's horsepower between its four tires is especially useful on loose or slippery surfaces such as sand and dirt, as well as on wet, icy or snow-covered roads. However it's important to remember that in order to transfer this extra power, the four-wheel drive and all-wheel drive vehicle's driveline mechanically connects the tires so they work in unison
This necessitates that four-wheel drive and all-wheel drive vehicles use tires that are very closely matched. This is because different diameter tires roll a different number of times each mile as a result of the variations in their circumferences. Tire diameter variations can be caused by accidentally using different sized tires, tires with different tread designs, tires made by different manufacturers, different inflation pressures or even tires worn to different tread depths.
As an example of different tire diameters resulting from tires worn to different tread depths, we'll compare two 225/45R17-sized tires, a new tire with its original tread depth of 10/32-inch and a second tire worn to 8/32-inch of remaining tread depth. The new 225/45R17-sized tire has a calculated diameter of 24.97", a circumference of 78.44" and will roll 835 times each mile. The same tire worn to 8/32-inch of remaining tread depth is calculated to be 1/8" shorter with a diameter of 24.84", have a circumference of 78.04" and will roll 839 times per mile. While the difference of 1/8" in overall diameter doesn't seem excessive, the resulting 4 revolutions per mile difference can place a continuous strain on the tires and vehicle's driveline. Obviously, the greater the difference in the tires' circumferences, the greater the resulting strain.
Rotating Tires
Because the front and rear tires of all-wheel drive and four-wheel drive vehicles perform different duties while accelerating, braking and cornering, tire rotation is important to even out, and maintain equivalent treadwear of all of the vehicle's tires to minimize potential driveline stresses

tire rotation-pros and cons (from dealer)
I rotated mine at the first recm interval (10,000) as i was changing my oil every 5,000. HOWEVER, in my case I have a 500 mile per week commute (highway) so I'm putting huge amounts of miles on my rdx in short time. When 5,000 comes around my oil is still at 40 or 50% so I'm going to go with the MID for oil changes, or 7,500 miles, whichever comes first. What this means is that I'll be rotating my tires every 15,000 instead of every 10,000.
According to the dealer, it might make a slight difference in wear, but the cost savings in oil changes will more than make up for it, and he actually reccommended I wait. Of course I realize that tire rotations and oil changes are really independent events and I could still rotate them more often, but I suspect that like most people, you aren't going to go into the dealer or other service center just for a rotation.
I think the most important thing is to ensure proper inflation, and don't just trust the pressure display in the RDX, (even if you have Nav and it shows actual pressure). Buy a good gauge too.
Oh, and one other thing... talked to the dealer about wear on the factory installed tires (i owned an '05 TL previously and they were notorious for only about 25-30K on a good day). He advised they haven't seen that many replacements yet, simply because most owners don't have too many miles, but they recently replaced the tires on an '07 at 45,000. Of course that was mostly highway miles, but at any rate it appears these wear much better than the TL
