We are in the mountains snowboarding and my 3yo son lost his jacket and gloves. I don't know the exact temp up here but it's usually in the 40s-50s here so that's what I'm guessing and it sure feels like it. When I took him outside to help him remember where he left his jacket/mittens he was shivering and his hands started going numb. Should I keep him inside the cabin until I find his jacket and mittens or should I still bring him outside and let him warm up by keeping him moving? I gave him my gloves and tied them around his wrists. He is also wearing a beanie, snowboard pants, a sweater, and snowboarding boots/socks. Can I take him outside and let him have fun with the rest of us? He's not going to freeze in 40s/50s weather right? Those temps feeling freezing to us doesn't mean he is actually going to freeze or be affected by it right? I mean people in colder parts of the world wear t-shirts in 15 degree weather! But his mother/my fiancee disagrees and wants to keep him inside.
Rubber is probably the best. You want it to be water and hydrogen proof, but it does not have to deal with heat.
You can use winter tires 365 days a year if you want, although it is a total waste in summer. There is only a time restriction on STUDDED winter tires, which damage the roads in warm weather. 39:3-81 Use of Studded Tires: Use of studded tires approved between 14 November and 1 April or as determined by director.
