Re: Treaded wheels vs Solid rubber
Speaking specifically about Colsons versus roughtop tread here. Other materials may vary.
Colsons wear very slowly, and basically do not need to be changed through an FRC season. Colsons have pretty good grip on carpet and are basically maintenance free wheels.
Roughtop treaded wheels require more maintenance (the tread may need to be changed once or twice per event depending on material), and they have an additional failure mode in tread loss. Depending on the wheel geometry, roughtop tread can give more traction than any Colson wheel can, though the difference is somewhat small.
If you want an easy, robust drivetrain with no maintenance without a huge traction compromise, go Colsons. If you want the best traction and pushing performance and you're willing to put in a little work in maintenance, go with roughtop.
