Typically, a bias ply tire will give you a little bumpier ride and the steering isn't as precise, especially at higher speeds. Although when you're talking that size tire, even a radial won't handle as well, as I'm sure you already know. One other thing to keep in mind is when left sitting, a bias ply tire will flat spot, especially when it gets cold. After being parked on colder nights, it would take 5 miles for my 44"s to round and smooth out the next morning. The other big problem is how quickly a bias ply will wear, especially on a heavier diesel. And if you do a lot of driving on the highway, the tread will disappear in no time.Ive got 40x15.50 toyo open country tires on my truck now. It doesnt ride the best, but with a tire this size I really didnt expect it to ride like a Cadillac.
So the ride difference between a radial and bias is going to be pretty significant?
It won't necessarily damage the tires over a short period, as they usually will fully round out after a little driving. But for the first few miles or so of driving after leaving it sitting for a few weeks, expect a pretty bumpy ride. Now if you left the truck sitting for several months or possibly years with full weight on the tires, they might not round out as well. But as long as it's driven a few times out of the month, they should be fine.My truck is not a daily driver......I drive it maybe 2 or 3 times per month if Im lucky. So with it sitting so much that may not be good on a bias tire?
