Here is the replacement tyre on the rear to the one I blew up ! The front is a Specialized Ground Control 4.6in, and the new rear is a huge bruiser Kenda Jugganaught 4.5in. Do my eyes deceive me, or do that rear tyre look much bigger and fuller over the front? I'm going to swap them over tomorrow and run the Kenda up front....the Kenda looks massive !!
