My Ram has a 305 40-22. Wide enough to be a problem?
No.
This picture is with the 265-40-22s that were on it when I bought it in 2007. I've had the truck aligned 3 times to the same settings. I run Nitto 420 tires and have never had a tire run to cords on the inside with tread on the outside.
My Charger has .75 degrees of neg camber and after 10,000 miles, I changed the tires only because they were 10 years old. The front treads have about 70 % remaining and even enough to have you think that they were on a solid axle trailer.
