We had the Nitto 3750lb tires on our truck , they rode well but I found the sidewalls to be very soft, they bulged out so bad that the truck looked like it was riding on the sidewalls. I was afraid of ripping the sidewalls out on large sharp rocks.
When doing the research on the Nittos, it did indeed look like TOYO and NITTO were the same outfit...or at least the tires all came from the same place...
Went with 19.5's and Michelin XDS, sidewalls very strong and straight, however need earplugs when on the pavement...wheels and tires now all 5000 pound ratings.. Ride is more harsh now...
