Don, the tires on the rear are Mich and my front I had to replace when the ball joint went is the agilis. The mich certainly aren’t cheap by any means but they have given me every mile they promise.
The batteries, now that info I knew, just not sure why it happened now all of a sudden. I don’t think I can fit the 6 volts without some mods. On the road of course that’s not an option for now. The batteries are under warranty at Costco but no Costco in Maine. So as soon as I get to a place I’ll replace for now.
