295/80 is a size that is not widely used in commercial trucking, so the choice of manufacturers is very limited. That means EXPENSIVE!!
Consider changing to 11R22.5, which is nearly identical in all dimensions but has slightly less load capacity. I changed my rears to 11R22.5 and saved $250/tire versus a Goodyear or Michelin 295/80. The load capacity is plenty for my 20,000 lb rear axle. I stayed with Goodyear G670 on the front, where I still need the slightly higher load capacity because it is a 13,600 lb axle.
