Hi guys. I just bought a center stand on Ebay and installed it yesterday only to remove it because the rear tire was too wide and would not clear. The rear is a Metzler in the recommended 140 80 17 size. I found Martin's tire guide which mentioned that some rear tires were too wide even in the recommended size and listed several tires that do fit, but it seems most of these tire models have been replaced with newer ones and in some case the sizes offered have changed slightly. I need new tires front and rear. I also want to be able to use the center stand. Any words of wisdom? Thanks Steve
