For sure! I looked up "Unsprung Mass" and read all about the weight factor that goes into the jounce of suspension. Fortunately for me the roads are kept well in AZ, no ice, snow, salt, rain to deal with. The biggest natural issues we have out here is the rubber parts drying out and breaking constantly because of the heat and sun. Ive got it in the garage now tho so its not a big problem. I think I will upsize and try it out. If I cant handle the effects I will just go back to the stock set I have on deck. Everyone seems to say it wont change things too much other than the suspension (if i keep the diameter of the wheels the same). The roads out here really are like glass for the most part.
