Airing Down: Setting Tire Pressure for Off-road

Once you start venturing away from the main roads, it won’t take long for you to get stuck your first time.  When this happens, you will start looking for ways to keep it from happening.  One of the first and most effective ways to improve traction is to air down.  Here we will discuss why it is done, when to do it, how to do it, and how much air to use.  It is important that you realize that this will serve as a guide only.  Your actual results may vary.  It is also critical to note that once you intend to do speeds in excess of 25 mph, you need to bring the air pressure in your tires back

Guide to Choosing Tires

Choosing tires is something that can be a pleasure if you know what it is you want to do.  A new set of shoes for your Land Rover can completely change its personality.  You can change it from a mild mannered highway cruiser to an off-road bruiser.
