TKC80s not legal!?
In preparation for a trip to Latin America, I recently had TKC80s fitted to my BMW F650GS twin. When double-checking the recommended pressures with Continental they sent me this slightly disturbing reply:
....
Slight problem with fitting TKC80's on your machine; the 110/80 B19 is bias
ply construction and the 140/80 -17 is cross ply construction.
UK law does not allow this combination however it may be acceptable in other countries, but I would check before you go.
The only recommended fitment for your machine is the ContiTrailAttack
Continental Tyres UK
....
Anyone know what the difference between bias and cross ply is?
Thanks!
