Replacement Tires

I just put on a Michelin Bopper front tire on my Z20b, and the handling is much better. Gives me more confidence to ride the scooter. It's a 120/90L-10 bought from here. I also bought a Michelin S1 for the rear, size 100/90J-10, but have not installed it yet. $79 including shipping for both. These are the ones previously recommemded by usatracy. The front has about 10% larger diameter, which partially corrects for the speedometer error. My top indicated speed dropped from 50 mph to 45 mph.

I bought some motorcycle tire irons to try and install myself and felt like I was banging my head against the wall. Could not even get the tire iron under the bead. I ended up taking it to an auto tire dealer, and they did it for me for $5.

Any other tires anyone has tried? Results?

I've generally been happy with Pirelli SL-26 tires on my e-max's. Much improved ride. They are reinforced tire with a higher max inflation pressure of 47 psi, I inflate them to 50 psi for lower rolling resistance.

As far as getting tire irons under the bead, did you break the bead first? With the valve core removed, and the rim lying flay on the floor a stomp on the tire with your heel usually works.

Use plenty of soapy water on the bead when prying it off the rim and avoid too much force to prevent rim damage.

Re: Replacement Tires

Thanks. Do you feel that the higher pressure contributes significantly to range? If so, by how much? The Bopper is only 25 psi.

Re: Replacement Tires

The odometer error with the new tire installed is about 7%. The speedo is probably now off by the same 7%, vs. 17% for the OEM tire.
