So... you're just about doubling your traction by switching to the tread. Not shabby, if you're robot is geared low enough to utilize it.

Note:
If you are interested in "wedgetop" just surf on over to www.mcmaster.com and type in part no: 60155K11

I also like the gum rubber "roughtop" - 5994K811
(What 229 is using this season).


May your wheels never slip, unless you're pushing an immovable object, and may your breakers never exceed 50 amps continuous loading,
John
