Hmm, I took a closer look at both those links, and the tires with the width I like are foam. I'll be doing more bashing in the street and paring lots than anything (not racing on carpet or high speed runs on a prepared surface) and would prefer something with a little more wear to them. I'm not sure what type of foams I had, but they wore down quite fast on the street. Great traction, but didn't last long.

On a related note, I was looking at that John's BSR site and am curious what "caps" are? http://johnsbsrracing.com/cap/index.htm

I prefer Jaco over Kawahara and all the other tires.

What I run on my MTX4R (nitro on road TC) There super dialed! And they look pretty sick also!

Jaco foams are very nice. Ive had two sets. One for my ext and another for my raven bx. Both lasted a very long time and really lightened up both vehicles. The tires way almost nothing.

I'm not exactly sure, Nic Case & others doing 100mph+ speed runs use BSR almost exclusively...might have to send an email & ask?
