Hi guys so right now i have a 2.30 in the front and back but my local bike shop guy said i need a smaller tires in the back because i have and older frame the tire it to fat for my back part of the frame. So should i stick with it or get a smaller tire in the back would a fat tire cause any problem on the back part of the frame. Yes or no for 2.10 tires in the front and back.
ref-momoney brought a frame.
