3) They call for floor flexibility test and tyre weight. Is tyre weight a wear measurement?
I'm not sure here, speculating, but it should be related to grain and blistering - to what extent the tire degradation and potentially the pieces that would fall off will affect the total wear of the tire. This is related to floor flexibility, because rules changed, and the deflection tolerance is smaller.
Just speculating; but could tyre weight be vehicle weight at the tire? Uneven tyre weights while probably not desired would also crank a bending load into the floor.[/quote]
Are we sure the tyre weight and floor flex test have anything to do with each other.
Just looks to me like that's two (unrelated?) things to do along with presumably a set-down. Floor flex test for legality and then tyre weight to look at tyre wear.
Like I said no reason to suggest they're linked.
