being that these trucks are 20 years old, they were made when the speed limit was 55, not 65/70 like they are now. with that being said what size tires are you guys running on your 15" wheels that are lowered? I know we used to run 195/50s or 205/50s and some ran 195/45s. to keep the same diameter as my 17s (215/45/17) I would need 205/60/15s. if you're running 195/50 or 205/50 what kind of rpms are you turning at highway speeds? with my 17s I'm turning 3300 rpm @ 70 mph
