BTW not DOT approved is not ticketable. If i am correct you have your old wheels and tires in your back yard for allignment, so you could still pass inspection with a quick swap. THat would be the only possible time you would run into trouble. There is nothing illegal about not DOT approved. as far as the 25 psi, there are several guys in my club that run them at 35 psi with 0 issues for several years. I will give you an update as I rack up the miles on these
