3-4 # !. I've been cutting back on the pressure, but, I haven't gotten that far yet. I'll try anything, so I'll see what happens. Actually it seems to be getting worse the more air I let out [softer ride though].
I'll play around and see what happens. I too was wondering about the low speed with balance beads. If I can't get this fixed I'll ask what tires are known to be good. I never gave bad new tires a thought.
It might be worth a try. I called when I first bought them, I took the cart down the road when first done with it , called and they were willing to do something. The cart then sat in the corner for 3-4 months until I brought it down south so I figured I had timed myself out.
