Modern Vespa

Hey all. So I've searched exhaustively both here and other sources, called numerous dealers, even talked to my go to oddball question mechanic and still Nada.

My GTS 300, kitted to all hell, have Yourban wheels on it (13 inch wheels) and it has the malossi 22/45 gears. Currently I'm running 130/60/13 Power Pure on both front and rear. My rear is finally done, so I'm getting new rubber. I wanted to go 140 rear for high speed stability, and a 140/60/13 is easily had in my preferred choices being City Grip or Power Pure. But then I got to thinking if I could mount a slightly taller tire I would eek out a little bit higher top speed. So I went searching for a 140/70/13 but of course that is a bizarre aspect ratio for a tire. Now I could order a 130/70/13 and get my taller tire at the expense of not getting the width I want or the other option is a 150/70/13 which they do make.

So question is would a 150/70/13 fit on the rear of a GTS? I eyeballed it and it looks like it would clear the suspension in the rear which seemingly is the only fitment issue. But no one stocks that tire locally so I'm forced to order online and I really don't want to have to return if it doesn't fit. So what say thee?

order it. if it doesn't work out ebay or craigslist or whatever forum /scooter that uses that tire and list it there.

Have fun with this. I think it will fit. When the GTS 350 comes out, i will buy 2 of the 13" front rims and fit a 130/70 and 150/70. Let us know how it goes.

How did the 150 work?
