An explanation of off-road tire technology.

00:00 When it comes to building our 4Xs, one of the most important decisions we make is the

00:09 type of tire we choose for our rig.

00:11 And while there are as many tread designs as there are tire manufacturers, they all

00:15 boil down to two basic types, the all-terrain and the mud-terrain.

00:19 A typical all-terrain tire such as this Nitto Terra Grappler uses an interlocking tread

00:24 design with evenly spaced uniform voids and hundreds of tiny little grooves or sipes cut

00:29 into each individual tread lug.

00:31 Aired down to trail pressure, these provide hundreds of additional biting edges on rocks,

00:35 loose dirt and sand.

00:37 They also display excellent road manners and while they're a good all-around performer,

00:41 they can also cake up quickly with mud and debris and they don't clean as easily as a

00:44 mud-terrain.

00:46 By contrast, a typical mud-terrain tire such as this Nitto Mud Grappler uses an asymmetric

00:50 tread pattern with large void areas between the lugs.

00:54 This type of tread pattern can provide excellent traction for low traction areas such as mud

00:59 or snow where sometimes you can't really get a grip on the surface.

01:02 They're also great for overall hard core off-roading but they're very loud and noisy on pavement

01:07 and the bigger you go in size, they can be very difficult to balance.

01:10 Now there's no such thing as a perfect tire for every single type of terrain.

01:14 So before you decide to invest in a new set of tires, assess realistically the type of

01:18 off-roading you're going to be doing, then check out the catalogs, ask the experts and

01:22 you'll be much better equipped before you invest in a new set of rubber.

01:25 That's your tech tip for the week.

01:26 We'll see you out on the trail.
