315/70R17 Falken Wildpeak AT4W too heavy for Colorado ZR2 Bison?

[OldNH]

Thinking of changing out stock Bison 315's with AT4W. Had that tire on many 1/2 ton trucks and like them very much. Anyone have experience with 315's or 35's on a Colorado? Stock Goodyear MT weigh 52 lbs and AT4W weigh 74-76 (depending on source).

My tires run 73lbs. No issues so far and they are smooth as glass on the road. If I am not mistaken the tire size you are looking at have 2 ply sidewalls. The heavier duty ones have 3 ply sidewalls. UPDATE: Just saw some more documentation that that specific size DOES have 3 ply sidewalls.

You're running that Load F tire on your Bison? Is it a stiff ride with the F rating?

Not really only running 70 in them. I run a different size on my big oil burner 2500 ZR2 of that same tire. Took this a couple of years ago. Have a lot of this at the ranch in NM. Why 3ply sidewalls are a must for me.

Well that stinks, no thorns here in NH. My Bison has the I-4 motor. Did you notice much or any loss in take off acceleration or in 4-H with the heavier tires?

Not really still will break them loose just a little. This vehicle with the axles locked gets around better than even my jeeps did. Was very surprised to say the least.
