Thanks, I somehow missed that place.
Boy, wouldn't I love a couple of those mud grips. They are just short of what I paid for the truck 52 years back. Each.
I had a chance 5 or 10 years ago at about $200.
I didn't get as far as tubes, S&H and local mounting.
At 65 PSI, seems a kidney belt and something to hold your teeth should be added into the cost.
