No, I meant tyres.
It had 8.5" tyres and now it has 10" tyres on the same wheel. The 10" refers to it's outer diameter, not the size of hub that it fits. Essentially it is a matter of changing it from a wheel with a low profile tyre to a wheel with a more sensible and much higher profile tyre.
>Out of interest, why?
Mostly for the obvious reason that you would expect, ride comfort, which is very noticeably different. But also a couple of other reasons.
With a 8.5" tyre there is very little air and thus cushioning. Consequently it is very easy for the inner tube to be pinched, and thus punctured, if one hits or runs over an object.
The lack of air also means that anti-puncture sealants don't work. The very small amount of air is gone before the gunk can seal a hole.
And also because the 8.5" tyre is so low profile, and so thin, that it is a b***** nightmare to put on and take off. Really really hard to the point where roadside puncture repairs are pretty much impossible.
With a tyre which will puncture much less often, and that I can change with my hands and no tools when it does puncture, and better ride comfort on top, then it's a no-brainer.
Though the scooter needed "adjusting" to get the clearance the much larger tyre needs.
Changes to it's speed / acceleration are actually an irritation more than an advantage.
