Re: [RC] Question about Truck Tires - Sisu West Ranch
"...and mandatory if in 4WD
vehicle, ..."
Actually it depends. If operating lots of
time in 4WD yes. If operating in 4WD on paved roads, yes (note this
assumes full time 4WD one never uses conventional 4WD on a dry paved road.).
If you only use 4WD to get out of slick campgrounds
or every so often on a gravel road, it is not a big deal assuming that the
rolling radius (size) of the tires is quite close.
The problem is that with conventional, part time
4WD there is no differential to allow the front to go at a different speed than
the rear axle. This means that when the rolling radius between tires is
different between front and back, one set of tires must slip across the
ground. Note: the same thing happens even with matched tires when you
turn, thus the prohibition to operating the vehicle in 4WD on dry
pavement.
Note that in full time 4WD differing radius tires
on front and back will cause the differential to work hard to equalize the
difference and cause extra wear on the differential, in addition to some
possible handling concerns.
