I searched the threads but I am still confused. I am looking at getting wider tires with taller sidewalls in the rear and I have the stock pony rims. What is the widest tire I can get on them? I was thinking anywhere from 245-275 for the tread width, and I do not know how high I can go with the sidewall without rubbing the fender. I know I already need spacers because my 225's are an inch from rubbing my pipes. So another question is what kind/size of spacer do I need? Basically, I am looking for applications that will not need any other parts or any other work. Thanks
