different tire size front and back

[wtfdissux]

with snow finally coming to buffalo I've been wondering since my front wheel drive is not opperational can I run larger tires in the rear ( for snow traction) and if I do should I disconnect the front drive shaft?

As long as your 4wd is unoperational there is no reason why you cannot. just remember that before you can engage the 4wd you have to change tires.

For a while I ran 38's up front and 38.5" in the rear. The rear tires were 1" taller due to being Bias ply VS. Radials. It isn't much of a difference but I also ran lower gears in the front axle. What I ran was 5:89 up front and 5:86 in the back. There wasn't a closer match than that. The front did grab harder but I really liked the control it provided.

In otherwords its doable. If the front is unlocked it doesn't matter what the tire diference is. Its just its havin a 2wd truck, just don't shift it into gear.

if the front is not working than you shouldn't have a problem

I wish I could shift the gear lol on a similiar note I have found that it is hard to find gears that are the same ussually can find 3:55 rears and 3:56 front have not seen the same for front and rear even tho they should be but think it is due to the fact that ford uses a 60 40 split on the 4x4 (60% rear and 40% front )

wish I could run a true four wheel drive with a 50 50 split and full time 4x4 instead of primary rear drive the tranfer cases and front parts seem to last longer on trucks with this set-up maybe becuase they are made for it instead of it just being there when needed/wanted

Please explain the 60 40 split the T case is a 1 to 1 . 1 turn of the front shaft to 1 turn of the rear shaft . And 99% of the time there are 3:55 in the rear and 3:54 in the front that difference is nothing you will see or feel . Maybe you were thinking the brake system that may be 60 to the front and 40 to the rear . /emoticons/[email protected] 2x" width="20" height="20" />

The 3.54 in the front is intended to slightly pull a bit more than the rear is pushing, and yes they are 1 to 1.

not talking actual power split am refering to use meaning that the t-case is part time not full time or all wheel and was guessin the gear ratio but you are correct on that found it amusing when I was looking to upgrade the gears in my truck
