Questions tagged [4wd]

Why do pickups and large SUV's use 4x4 and generally not AWD?

In almost every case I can think of, the larger vehicles with four wheel power are 4x4, and the smaller ones AWD. As far as my experience goes, AWD is much more convenient, and also works at least as well on ice as 4x4 (at least 4h), and allows a…

I have a Ford F150 4x4. The front 2 tires treads measure 12/32, one rear is 6/32 and the other is 10/32. The dealership told me I should replace the rear 2 tires because the big difference in tread depth will cause the tires to spin differently…

Does 2WD mode save me gas over AWD(auto) mode?

My 2015 Nissan Pathfinder has a switch for 2WD, AWD (auto), and 4WD Lock. Do I save gas by keeping it in 2WD? Or it doesn't matter because it's still the same drivetrain and it simply doesn't apply power to the rear wheels?
