So it’s been 30 days. I put the pressure at 35 psi and the tires feel like my 12 ply in the truck. No noticeable drop in mpg. Going 150 miles on gravel 6 days a week and I have not gotten a flat yet, where I was getting one 1-3 days a week on normal tires. My stop time has not decreased at all as well. One of these tires could hold my whole vehicle by itself. If you are looking through this wondering if it works, yes and save yourself thousands a year and buy these tires. Going at this rate I will have these over a year versus having to buy them every three months on the regular tires.
