You could say it's where the rubber meets the road.

In a sign that Sears Holdings Corp. (SHLD)  is seeking more funds to prop up its ailing empire, it announced on Tuesday, June 12, that 118 Auto Centers, up from 47, now will be available as service centers to install tires bought on Inc. (AMZN) - Get Report  .

The legacy retailer announced the ship-to-store collaboration in May. The service is rolling out at centers across the country, the company said.

Sears' DieHard brand tires are available on, but customers can buy any brand through the e-tailer and have them installed at a Sears Auto Center.

"Amazon customer reviews have been very positive, and we are two months ahead of schedule," said Mike McCarthy, vice president and general manager of Sears Automotive. "Customers are taking advantage of additional services during the tire installation process, such as oil changes and alignments. We are meeting our 60-minute tire installation commitment, and over 90% of the Amazon customers are new Sears Automotive customers."
