You need either the GM magnet tool J41760 or a fairly strong horseshoe style magnet since most shop-style nuts/bolts pick-up magents will not be strong enough.
1) Key in ignition in on position
2) Press lock and un-lock buttons on the fob till the horn chirps
3) Starting with Left Front tire hold magnet against valve stem until horn chirps then work your way around vehicle clockwise. After the Left rear tire horn will chirp twice to indicate that programming is complete.
Not exactly:jjd454 said:I was reading in the owner's manual and noticed it said, "not" to rotate the tires.
In my own experience, once you notice any unusual wear, you have already significantly shortened the life of your tires.Tire Inspection and Rotation (page 6-57)
Your vehicle's tires should be inspected regularly for wear. Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. ...
I just had a pretty harsh lesson on the XLR tire wear. I didn't rotate them for 10K and notice "unusual" wear on just the rear tires. The wear was even but unexpectedly large for 10K of use. The front tires are wearing very well.Caly said:Not exactly:

There is also a tire rotation diagram in the manual.

Spend $85 and get a good 4 wheel alignment. The factory does not do all that great of a job and I think it is routine to find the rear alignment out pretty much and the front OK.alk3997 said:I just had a pretty harsh lesson on the XLR tire wear.

It turns out that, according to Discount Tires, if the tires are not rotated the rears will wear faster than the fronts since the XLR is has rear wheel drive. They recommend rotating every 4K to 6K miles. The first set of tires were rotated and we got 19K on those.
So, two more tires have been ordered (the same Michelin models). A local Cadillac dealer (not the one I use) said that not rotating is recommended and that the customer just has to buy more tires. That wasn't exactly customer friendly advice.
I'm curious if anyone thinks I should contact either Michelin or Cadillac about the rears wearing-out in 10K?

Those are the best looking wheels I've seen for an XLR yet. What was the lead time to get them made?standby said:I'm getting 3 piece rims made, and bought 4 sensors from GM, will they know what to do with the sensors at a quality tire store? (Grand Prix-Newport Beach)

3" inset is about 3 times what I thought they could get. Do me a favor and measure your front tires outside edge to outside edge before and after. It will be interesting to see how those fit.standby said:I have to add a note here. I just came back from Grand Prix and saw my rims. I wasn't totally happy with the fact that they weren't deep dish. The designer told me the offset and clearance for calipers would not allow him to make it a deep dish rim. Inset from the outside was only about 3". After he put one in front of my old wheel, I was a little bit more enthused, it certainly was 100% better than the stock rims. There going on tomorrow or Saturday and I will take pictures and post them. You guys be honest and tell me what you think. The designer said lead time would be about one week because he now has the design made.
