How cold is too cold for the tires to safely grip the road?
Can one get as aggressive in the twisties on a cold day or more aggressive on a hot day?

When any moisture on the road becomes ice.... Then it's too cold...

So I'd have to give you the big 32 degrees.....

As long as the road is dry, It doesn't matter how cold it is...Within reason...

There's safely grip and maximum grip. A few years ago I had a pass to the pits for qualifying and practice for the Daytona 200. I noticed all the tires wrapped in tire warmers. So I figure the warmer the tire the better the grip. Say what you want about superbike racing but you sure could tell when a Harley racebike was on the track!

The temperature of the road is not as important as the temperature of the rubber composition in the tire. Putting the dangers of frost out of the equation for the moment; to compensate for colder tire temperatures, you can deflate a couple of pounds of air on each tire and compensate...........a little................making sure that you check you tires on a regular bases so they are not too deflated when the ambient temperature returns to normal..............experience is your best friend and can not be replaced in this situation.

But watch the frost ALWAYS and do B-Safe......................... :cool:

They're racing slicks that need to be hot so the rubber melts and becomes sticky.

The coldest I've ridden in was -8.5c (17F), but the road was very dry so no ice. It seemed ok, but I rode very carefully, and my route was almost all motorway.

Hi,
I ride in Southern New England and I ride 12 months out of the year. Obviously, you don't want to ride when there's ice on the road. Temperature range for icing on highways and bridges, formed from dew, is between 24 and 36 degrees, generally speaking. The bridges will ice over more quickly than the roads.
That being said, if you are like me and inflate your tires on the hard side, then you'll want to reduce those pressures, in cold weather below 32 degrees, to the BMW recommended pressures. Then, when you first go out for your ride stay below 40MPH for the first 3 miles to let everything warm up. I ride a bit less agressive in below freezing temperatures.

The temperature of the tires makes a big difference in the amount of traction you get.. I have felt the LT slip a few times in cold weather before the tires were good and warm and did anyone see the Daytona 200 this year?? it was a cold night and several bikes went down in the 1st few laps before the tires were hot...
