    So everyone.

    I'm a lucky man, i recently discovered my vmax gen 1 has 17 inch wheels. (it's only a couple of months ago i got the bike, so yeah im a fool i know)

    and they dont need to be replaced right now, but for a future change i better do this research.

    At the rear my current tire is a 170/60-17 (i cant remember the load index for this tire right now but the original is 74), at the change i would like to go 180 i think i have the space, so the options would be for an example:

    Pirelli Angel ST 180/55-17 73W

    or

    Pirelli Diablo Rosso III 180/60-17 75W

    The 180/60 tyre does have a higher load index than the original tire so no problem there BUT the 180/60 is almost double as expensive as the 180/55 tires (and i like the idea of a little lower profile)

    The problem with the 180/55 tire is that it only has a load index of 73 in contrast to the original 74 tire (about 10 kg less)

    Would this be a problem? and/or how do i find the maximum axle pressure of the vmax?.

    Thanks for your help! :)

    The load index isn't going to matter much unless you AND a passenger both weight 300+ lbs
