Cheapest place to get Bit Racer tires?
 

where can i get cheap bit racer tires because i dont want those fruity looking colored bit char-g and microsizer tires. And are the KITT racer tires plain black like the bit racer

the microsizers set is the same exact thing as the bit racer set...dont ask my why, but i bet you can get them at a hobby shop.

The MicroSizers tires are not colored:

They are the Bit Racer tires! ;)

but the why do the soft ones have to blue?

They're really more of a grey than a blue. And the softest ones aren't those.

which one are they

The older tires were all black. I know that the AE86 Tuner kit, and the older optional tire set come with the soft black tires. They are probably color-coded so people don't confuse them.

The cheapest ways to make tires is to make them yourself! It's really not that complicated, just get the grips off of pens and cut them you your wheel width, and voila!
