Cooper Discoverer HT3 or Firestone Transforce HT

I put TransForce HT's on my 5th wheel, love them except for concrete grooved roads. Makes a heck of a racket on those but I see nothing wrong with them. Ran cool, 114F in the shade, 119F in the sun and this was 95 degree air temperature plus they track well and no wandering. Premature wear, don't really care. I will probably have to replace them from age well before they wear out.
