The best Tamiya tire is the pre mount S-Grip tire. I think the # on that is 1016. If you plan to do TCS racing, you will have to use this pre mounted tire set.
They are "tricky" tires to use, but once you get the hang of them, they are very good. One set of fronts last me one day and a set of rears will last 2 days.
A set of Pit Shimizus last four or five times as long and are cheaper. The disadvantage is you do have to glue them yourself and if you mix them up, it's hell trying to straighten them out. They are also a better performing tire and what I tend to use on a fun day. They also work on the set up I just posted with no changes. The S-grips also work, but you do need to make some adjustments.
Amazing info guys ..Thankyou very much. This just in...I was racing in the parking lot today on my lunch and smashed into my tire on my car...the spur gear stripped teeth. So now it REALLY makes that horrible sound. I'm going to disassemble it tonight hopefully if I have a spare spur in with my parts and I'll see if I can get her running tonight and post some pics of what I have.
Is there any upgradable (tougher )spur gears and dogbones and gears that I could get that have a longer lifespan or will the one's that come with the ball diff be good enough??
