With tyres the only constant is the wheel size, internal diameter. Overall diameter depends on the tyre makers original design use, type of compound, and tread pattern. Off Hyway, Mixed use, On Hyway, Long Haul or Urban. Steer, Drive,or Lift Axle.Then you get into Pneumatic Specialist Pneumatic, or Solid. I once drove a rig on the docks with a mix of Pneumatic, Pneumatic with tyre fill and Solid on different wheel stations.
