Tyre Sizes

[rocketian]

Just trying to order some new rear tyres from Blackcircles for my 111R.  Last set I had were 225/45/R17 91Y.

 

Seems a bit overkill to me - should speed rating be V and what load do I need   -   90??  Handbook is no help and B'circles just say - order what you had last time !

Oem AD07 LTS were 80W front and 91W rear for 175/55 R16, 225/45 R17 sizes.
