I bought these tires because of the good reviews from RV owners, I put them on my 2008 dodge ram 3500 4x4 single rear wheel to add some load carrying capacity for my heavy fifth wheel, So far they are working great one trip from Hermiston OR. to Boise ID. in the snow all the way and they didn't slip or spin. and carried the load well. Very fast delivery by simple tire only two days. They also look nice installed, I have had several positive comments. Thank You Simple tire
