Belief it or not, after the truck it self, the off road tires along with the appropriate wheels are the most important ingredient to a good usable 4x4!
You probably often hear people arguing about the "correct" off road tires for use. What size you should use, manufacturer, alloy or iron -
but the fact is no off road tire is perfect for all conditions. Although it is all debatable I will try and sort it all out for you. I am going to tell you how to select the best off road tires for your truck.
The tires I have used most are Gumbo Monster Mudder 38x15. The wheels are standard 15x14 white spokes. Does anyone know of an online source for these tires? I would be glad if someone can enlighten me. For snow wheeling in Iceland these have proved to be the best overall tire. They work great for airing down and have lasted a really long time.
Nitto Tires in King of the Hammers The Ultimate Desert Race Since I am going to the King of the Hammers this season I wanted to know about some of the tires that are specially built and designed for the event. Nitto tire expects great results at this year’s Ultra4 sanctioned King of the Hammers race. The tires are called Trail Grappler® Race Tires and six sponsored race teams are using them.
PitBull MadDog Tires Review - I just got a big package sent from the USA. A set of brand new PitBull MadDog 39 inch tires for me to put to the test and share my findings. PitBull tire manufacturer are focusing first and foremost on the off road market and that is a great plus. They are therefore more in touch with the needs of 4 wheelers.
The first question you must ask yourself is which type of tire you want to use. There are both radial and diagonal. Always choose radial tires if they are available! Radial tires have better road traction, provide a softer ride and usually last a lot longer. Larger than 38 inch tires are usually only available as diagonal.
I am not sure if everybody knows this but a good tire size depends mostly on your vehicle weight!...
Size matters !
|Weight||Tire height||Wheel width|
|Super light||1000-1400 kg||31" - 33"||10"|
|Light||1400-1800 kg||35" - 36"||12"|
|Super heavy||3000+||Find something bigger!|
These recommended tire and wheel sizes should be adequate for even the toughest terrain!
The larger tires are better to air-down. By airing-down you increase the grip and make the ride softer on rough terrain.
The second question is which tire tread to use. Ignoring all "religious" issues is hard, but I will try to explain.
There are basically four types of tire tread to use for trucks and SUVs.
These are intended mostly for highway use, so I will not describe them any further here!
Provide a good balance between drivability on the highway and traction off roads. They are good to use in dry, powdery snow, also reasonably good on ice and in mud, but perform rather bad in wet snow.
Give the best overall grip in sand, dirt, rocks and snow and reasonable grip in most other situations. They are especially good in wet snow and mud. They are however considered noisier than the finer treaded tires.
There are various special tire treads like this Super Swamper Bogger. The Bogger is designed for heavy mud, but could prove usable in other situations.
For serious off-roading I would suggest you aim for the mud terrain type of tires since they give the best overall grip in sand, dirt, rocks and snow and reasonable grip in most other situations. Something like B F Goodrich Mud Terrain T/A, Buckshot Radial Mudder, Denman Ground Hawg and Mickey Thompsons Dick Cepek F-C Kevlar. For the 44" tire I would recommend the Mickey Thompsons Fun Country Nylon Belted.
Terrain and temperature conditions can of course vary a whole lot. From the hot dry soft sand and solid stiff rocks in Sahara to the freezing arctic powdery snow or hard and slippery ice. Too hot and the tire might be ruined easily by too little air-pressure. Too cold and the rubber will come stiff and might crack.
Traction is important to continue momentum under all conditions. Loose it in a middle of a steep slope and you will know it! The off road wheel is responsible for upholding proper grip at all times.
Tread and sidewall rubber compounds are designed to perform under various conditions. Off road tires have different characteristics. Thinner sidewall means they are softer and have less material resistance with low air-pressure. Thinner sidewalls also usually mean less weight.
Clearing of water, mud of ice out of the tire tread is important to maintain enough traction.
Driving ON snow demands that tire distributes the vehicle weight over as big area as possible. This is called "floating". Same goes for other types of surfaces, like mud or sand, where you don't want to dig in too deep. Only problem there is that you don't get the cooling effect of the snow!
This should give you some ideas about which 4x4 wheels and tires to use!
