I cut three pieces of wood to 6 1/4" to comp for the tire wall thickness and eyeballed the expanded tire to see if it would fit and seat the tire beads. It looked like it would work. I mounted the new tire and inflated / deflated the tire several time, each time banging the tire on a hard surface to allow the inner-tube to fill the tire properly with no folds or pinches.
I then took the tire up to 28 PSI and ran the
bike up/down my back road several times at different engine speeds making sure to hit as many rocks and boulders as possible to help seat the tire beads.
I then dropped the tire down to the recommended tire pressure of 7 PSI and repeated the trip on my back road. ( 6 ply rated tire)
I then climbed a very steep hill to see it the tire was spinning on the rim, and it was not.
The rear tire has much better control on leaning the
bike into a corner. It can get a little squarely if one of the tire lugs hit a large loose rock while in a turn. Just something for me to remember in the future.
I want to thank FOMOGO for convincing me to try the tire as it really looked like it would not fit the rim.
The rim is exposed on the left side of the
bike a little and that too will have to be remembered as getting a replacement rim is darn near impossible these days.
I'm hoping the new tire will give me the traction the original lawn mower tire could not.
The tire is 19 "vs 18" in diameter. The top speed of the
bike was increased a couple of MPH, which is a plus but were I ride your not going to be riding flat-out anyway.( 57.15" roil vs 60.32" roll )
New vs old tires
New tire mounted on rim and inflated to 28PSI
Tire mounted back onto
bike and inflated to 7 PSI.
