I will get new ones but I don't think there's a huge rush.
thanks, I wont drive 200 miles (each way) for tires though .
I'll use more in gas than the 10% savings.
FYI, I think I might switch to Nokian Hakkas when I need new ones because they don't seem to have the 1/2 tread issue that Blizzaks have.
That 14% is without a change in tire compound. I'm cheap! I'll live with 86% snow traction; 86% of the Hakka snow traction is still better than most new winter tires. I don't think I would want to add the loss attributable to switching to the non-miracle rubber compound on top of the 14% loss. I see a lot of freezing rain here. There's nothing like a layer of water on top of nicely polished ice to make you appreciate your winter tires' rubber compound.https://www.consumerreports.org/tires/make-sure-your-tires-have-enough-tread-for-winter/
Consumer Reports tested worn snow tires. Money quote:
In CR tire tests, we started to see a decline in the performance of tires with half their tread depth still left.
Snow traction when accelerating fell by 14.5 percent and wet stopping distances increased by about 7 percent, among other findings, when the tires were compared to new versions with full tread depth.
All the tires tested worked well in dry and temperate conditions.
Half the tread depth is where Blizzaks run out of soft rubber, and a little less than the wear bars.

.. or maybe you can ping the Ice driving school folks for coupons! Is there still a Bridgestone Ice Driving School at the boat?
But your Jeep dealer is going to be doing he body work after the wreck.

When Blizzaks are down to the first wear bars, they have about 6/32 of tread left. That's not enough for a usable snow tire, regardless of the compound. The dual compound doesn't reduce the life of a Blizzak at all, it just gives you a quieter tire (because the hard compound dissipates heat better) and a better summer tire at the end of its life.
The OP is from Steamboat(Ron).You may already know this but Colorado passed a new tire requirement for winter driving. A long,127 mile section of I70 west out of Denver
now requires a minumun tread depth of 3/16" on all vehicles, 2x4,4x4, and all wheel drive. Chains or tire socks in the vehicle on 2x4 to be available if road conditions require. Rest of the state still has a 2/16" minimum requirement. Folks visiting Colorado may not be aware. (Although I sure wouldn't hit the I-70 sh*t show without 4x4/ AWD and GOOD tires). FWIW, Tire Rack advises replacing tires at 3/16" also. One other thing to think about; the coating on the tires inpedes maximum traction until driven a couple hundred miles. So don't think they suck if you get in some snow at the get.
