Why I Replaced our ST Tires with LT

Why I replaced my ‘ST’ class tires with ‘LT’ (and all that entailed).

  • Very near maximum loading.
  • Few tire options in 15″ rim diameter.
  • Unsettling to know you’re running at maximum rated speed of tire (65 mph).
  • Personal experience (5 instances of tire failure with ST).

There’s no shortage of discussions on this topic:
