Altra High Performance Tire TSB for GM Cars

[VLS_GUY]

GM released a TSB (#13-03-10-001A) about the use of Ultra High Performance Tires below 40 degrees F. It seems they loose grip and can crack below this temperature. In fact they recommend not moving the car at all below 5 degrees F or the tires will crack. See the consumers report post on this as it is the best source of information on this: http://consumerreports.org/cro/news/2014/03/performance-tires-crack-winter-cracking/index.htm
I knew Ultra High Performance Tires had basically no warranty but for an OEM tire don't you want your customer to be able to drive off in a new car no matter what the weather?
If any of you have put UHP tires on your daily driver have been warned.
It looks like Chinese tires do not have a monopoly on tire cracking.

Look on the bright side, if you can't drive it due to the tires, at least you are not risking being killed by the ignition switch.

They turn hard under cold temps. Almost like driving un plastic. I went with all season tires in my vette. In cool weather on rainy days the car was scary on just a basic turn out from a parking lot.

Wonder how many idiots in the last few snow storms didn't know this. I noticed plenty of sports cars left abandoned on the freeway in Atlanta.

Even my ST came with warning stickers on driving it below 40 degrees with the stock high performance summer tires. I would just consider it common since that you not drive summer tires in the winter assuming you live in a climate that has a winter. Every high performance summer tire I've purchased says that driving them in cold temps will damage the tire and result in compromised traction. I'm shocked they needed a TSB for common sense.
