The differences are the size and the purpose. Regular tires are made to grip the asphalt, and also fitted with grooves to push water away, keeping it from hydroplaning. The off road tires are thicker, and the grooves are much deeper, giving it the ability to have good traction in the dirt and rocks.
Off road tires differ from regular tires because they are created specifically to be used off road. They are more durable and are engineered to be stronger and preform better at higher speeds than regular tires.
The difference between mud tires and rocky terrain tires are minimal but fairly different. The mud tires are designed with large and chunky patterns designed to grab into the mud, while the grooves on the off road tires are meant to gain traction with the dirt and gravel.
Buckshot tires are best used on vehicles for off-road driving. These tires are more durable and have better grip on a variety of terrain compared to regular tires.
umm the road, friction between your tires and the roads surface.
It depends on what weather conditions you are driving in. If you are driving in harsh snowy weather then studded tires can be your best friend. They will help you produce traction on a road that is slippery and icy. On a regular dry road, you do not need studded tired, they can damage the balance on your tires if you drive with them too much.
Gravity and also the traction between the tires and the road. The ridges on the tires sort of grab the road so you don't slide, especially on rainy days.
The friction between the road and the tires creates and screeching sound.
The term is hydroplaning.
If you plan to spend the majority of your time driving off road, you will need thick tires, probably between 35-44" wide. Most of these tires will last between 5-10 years, but may only last one if you drive at excessive speeds over difficult terrain. Most off road tires cost between $100 and $200.
Pro comp tires are known to have good traction in wet, off-road conditions. If you're going to drive the vehicle on the highway very much, know that Pro comp tires are loud. For what it's worth, I think Pro comp tires look much better than regular tires.
There are different types of tires depending on what kind of racing they're doing. But pretty much all racing tires tries to be grippier than regular tires. This usually means that they wear out faster, and create more road noise than regular tires, which no one really cares about if can win them the race.
The water creates a layer between your tires and the road so your tires don't grip the road, they lose traction.
