How do I find the ratio for a B7510 HST with R4s. The fronts are Titan 23x8.50-12, and rear is Titan 12-16.5. Time to start thinking about new tires as these are full of sidewall cracks. Some early looking indicates Titan no longer makes the exact rear tire anymore. Any ideas or advise is greatly welcomed. Thanks. I guess what I am trying to find is the gear ratio of the drive train, is this listed in the WSM ?
