Yeah I used to always run 26" tires but when I put the 325/50/15" Dragradials I was mostly running n2o so I left them on until last weekend. I had my old 15x8" Welds and a used set of 26x11.5" ET streets and put them on to go racing b/c I knew it would run about .2tenths slower with the 28" tires. Now I have a set of 3.73's waiting to put in but I hate changing too much at one time. Later Clint
