It is hard to say how the car tire will work out , I have not tried mine yet, but Danny says it is a smoother ride as side walls are softer and it should last a lot longer than bike tire. I used 2 tires last year, first one I ran with low air pressure to get a softer ride and wore out the tire, the last one probably would have got 5000 km out of it but I cut it off to put car tire on. I think a car tire should last a couple of years, better traction and give a smoother ride, but only time will tell.   Wayne
