Bulletin says replace tires with cracks

Order Reprints

A recent General Motors Corp. technical bulletin has Modern Tire Dealer Editor Bob Ulrich worried. It involves cracks on tires caused by cold weather.

The bulletin, written about on www.consumerreports.com, says the following:

1. UHP summer tire compounds harden when it gets cold.

2. The cold can cause cracks.

3. If the tires have cracks, they should be replaced.

Is it really as simple as one-two-three? Is the bulletin really implying that all tires that show signs of cracking should be replaced, or just cracking caused by the cold?

Is government intervention just around the corner?

To get a better idea of what all the fuss is about, check out Ulrich's latest blog, "Combining UHP and winter tires is not all it is cracked up to be."
