IM now a truck camper guy but use the same tires towing various trailers.
I run 265/16 tires , but these tires are avl. in your size.
I have run Bridgestone REVO 2's
Cooper AT/3 's
Both were VG tires. The Revo's made more road noise but the wear was about the same.
I have no complaints with the Cooper AT/3's, very quiet , good in all kinds of road surfaces and weather conditions. They were great in the snow/ice.
Michelin LTX/T2 is also a good tire in your size. I have NOT used them, but were recommended to me by the tire shop as an equal to the Coopers.
I went with Cooper because i always had good luck with them and they worked so well, i seldom had to use 4x4.
You look here to check 'specs/reviews' rebates are avl .
