Considering installing rim/tire screws to enable me to go to a lower rear tire pressure. I talked to frankenstein and they told me I needed to stay above 20psi to avoid tire/rim separation. Well, I have been down to 16psi for a long time and the ride is much softer. I would like to go to 10 or 12 for the softer ride. I hoped maybe some folks have tried this. My tires are 60 series, short and fat. I think 195/60/15. About 11 inches wide.
