Here is another one of those strange free BlackBerry promotions.  Buy four tires from National Tire and Battery and get a free T-Mobile BlackBerry 7100t or 7230.

It looks like the folks over at NTB have teamed up with to offer a free BlackBerry to anyone who buys 4 tires from NTB during the month of August.  You can get your free BlackBerry in one of two ways.  Either call 1.888.802.8587 with your invoice or log onto with the following promo code: TKNTBMTA.

All requests must be made before September 30 and a one your voice and data plan from T-Mobile are required.  Offer is good at participating NTB, Tire Kingdom, and Merchent’s Tire and Auto Centers.
