Hello. I have an 1980..ish tamaya frog. Sand Rail. I have started to rebuild the car. But the tires have rotted away. The rims I have for the car are 3 pices. Screwed togeather with 5 screws. the rear rim measures... 2 1/8" X 1 316" with a brad of 1 1/2". I am looking for knobby tires, and paddle tires for the rear. Is there a special type of tire I should look for? Or will most tires fit thease rims?
