Randy,
You say in your topic that these are "Steering tires". Does that mean you are only replacing the two front tires? If so, are you replacing 7.50 R 16 tires with the 235 85r 16 tires? The reason I asked is that I had 7.50 R 16 tires on my Allegro coach and replaced them all around with the 235 85r 16 tires and had to change them back to the 7.50 R 16 tires because they were too close on the dual rear wheels. Even though the two sizes are virtually the same height, the width on the 235's caused a problem on the rear. If you are just using them on the front, there should be no problem, except you won't be able to rotate them with the rear if the sizes are different. Also, the load range E tire rode a little more harshly than a load range D, but then, your coach may require the E for the carrying capicity. I put Cooper Tires on my coach and so far like them. I've had B F Goodrich tires on other vehicles in the past and liked them as well. Good luck with them.
