Flexing? (Score: 0) by Anonymous Coward on 2017-01-06 04:18 (#27VPA) They probably can't handle speed too well, so probably no application on cars? Re: Flexing? (Score: 1) by email@example.com on 2017-01-30 16:31 (#2ATNK) Normal car tires flex in about the same amount. If they didn't flex they would be very hard and seriously impact handling from both a ride-harshness standpoint and a grip standpoint (harder rubber = less grip). The flexing also allows for a larger contact patch with the road.
