I hadn't seen this one listed. Go to Member's Home, and it was listed under Today's Features.

"Receive tire-performance tips, special Michelin offers and 50 Points. (Once) "

Seemed simple enough:

"Get the most out of your tires, plus earn 50 Points!

Take advantage of Michelin’s free email service to receive tips on tire care, special deals and more. Registration is FREE, and you earn 50 Points. Plus, you'll recieve an email with instructions for how to receive a FREE Palm Zire when you buy 4 new Michelin tires. Click below now to register!

NOTE: You won't see an automatic confirmation of the award for this offer. The Points will be available 10 business days after you complete your transaction. In addition, to properly credit these Points to your account, the name and email address you use when you complete these transactions must be exactly the same as your MyPoints account information. This helps to identify your Point earnings accurately."
