8" Non-Pneumatic Wheels

I think you are talking about this type of wheel, right?

Yeah I would avoid the rough terrain because the blocks are spaced out a larger width than the wheels- but hey you most likely will be allied with a team that CAN pass rough terrain and again its only one defense.

Given this is likely to be a game with vigorous robot to robot contact how would those hold up to being T-Boned?

Yes, That's the one.

Have you checked whether the larger 8" wheels will collide with the front and back "C" frames ? If so, is it possible to notch the frame to accommodate the extra 1" wheel radius ? Else you have to move the axles and then the belts don't fit.... Or extend the frame

Also keep in mind when going from 6 to 8 inch and not changing any gear or belt pulley ratios, the robot will go slightly less than 8/6 times faster. Though your driver does has a "throttle", it might be somewhat harder to control the robot in close in maneuvering. And the robot will have 8/6 less torque (in a pushing match).

There is a separate pair of axle holes for 8" wheels already in the inner and outer plates. You will need to get shorter belts, as specified in the KoP documentation.
