4x4 Mud Tires 

The main purpose of 4x4 mud tires is offroad driving, especially in locations with soft and greasy mud that require agressive tread patterns to plow through the dirt. Such tires are not really good for regular use, as they are very noisy on regular roads and they wear out quickly when used on asphalt roads. But seriously, you wouldn't buy a set if you just want your 4x4 to look cool, right? You want the blood, the sweat, the tears, and yeah, the MUD!

There are three main categories of offroad 4x4 tires.

1. All-purpose tires

Those tires are suited for traditional roads, but will allow you to have some fun on easy offroad patches and bumpy backroads. If you wander off to some dirtier and wilder places, they won't give you enough traction and endurance to make it through. They can be usually found in those fancy SUVs, they do really well on asphalt, don't make too much noise and last for long time.

2. All-terrain tires

Those tires are prepared for some more action and some more agressive rideng than in comparison to all-purpose ones, and certainly will do great on more demanding surfaces like deeper sand, and rocks. If it's needed, a car equipped with those can get through mud too, of course if it is not too adhesive or tricky

3. Mud tires

Finally, the 4x4 mud tires. These rubber buddies are best prepared for hard-core action and dirt, and are suitable for really agressive driving. The spaces between the knobs are usually wide, which makes it easier to drop off the mud so that it doesn't stick into bigger parts and stop the tires from digging in. Purchasing 4x4 mud tires is different than buying all-purpose tires and all-terrain ones.

Firstly, the mud tire sizes are usually larger than the others. This is caused mainly by a need for wide spaces between the treads. The second reason is, of course, bigger tires just look better, and you can look down on those small-tired guys. But beware, there are limits of cool. If you go for too big size, it will result in problems with tracking, you will find your wheels rubbing against the car body, and you may damage your suspension.

The key factor that differentiates the 4x4 mud tires are the patterns of treads. Of course, there are better and worse ones, but as long as the treads are knobby and have wide spaces inbetween, they'll do just right.

THe last thing you need to remember is - these are not tires for regular commuting - they have bad traction on asphalt, make a lot of noise, and will wear out quickly on surfaces they are not suited for.
