do have have to do any thing to my rc10gt to run it in the snow?

Cover the battery in a ballon. Get an RPM reciever box and put a plastic bag around the reciever, then put it in the box. Plastic dip the servos. Have fun!

maybe get some paddle tires, so you can get some traction

You need to keep and eye on the temperatures and make sure they are not to low. If they are try wrapping something around the head to cut down on the cooling like aluminum foil. You want to run at least 220 or better. I prefer higher.

You have to have paddle tires in the snow. Other wise you wouldnt get any traction and you would over-rev you engine.
