I was wondering if anyone could clear this up for me. Seems as thought that the most popular tire choice seems to be m-grip, s-grip, and 60D slicks of some. Seems that most have some sort of combination of these. I have been driving myself crazy trying to find the right ones on Tower. Seems like there are a million differenet tires from Tamiya. Can anyone PLEASE tell me the part numbers for the following 3 types of tires? I would like to keep an assortment on hand once I order becasue tamiya parts locally are not the easiest to find. THANKS.
