1What is the difference between taller tires and wider tires?
This really has to do with the differential and the chassis. The taller the tires the more clearance it gives. While, the wider the tires, the more traction you will have.
2Why is that four wheeler’s usually have 35 inch tires on?
The reason for four wheelers generally having this size tires on is that it is a requirement of most trails for them to have either this size or smaller.
3How do you put on a tire that is larger than a 31 inch, on your rig?
In order to put on such a tire on a rig, you will definitely have to lift your vehicle. Also, there are different laws related to lifting, in each state, so, first you have to be familiar with those laws.
4Do I have to do anything special, to re-balance my truck, when I go to a larger tire size?
Yes, when you go to a larger tire size, you have to re-gear your front ends, as well as your rear ends. You have to do this in order to offset the size of the new tires.
5I want to lift my truck. Is there anything that I should be concerned about?
Yes, when you lift your truck this is what happens, the center of gravity of the vehicle changes. When the center of gravity for your truck changes, the chances that you will have rollovers will increase.
6I have noticed that most four wheelers drop the pressure of their tires for the trail. Why is that?
This is because they want to increase the traction.
7Is there any disadvantages of reducing my tire pressure for the trails?
Yes, there is. A low tire pressure limits the speed of your truck. You may notice that with a low tire pressure your truck will seem to be under performing at speeds that exceed 15 mph. Also, your gear ratio will be lowered, somewhat. You should also bear in mind that this makes the sidewalls of the tires more vulnerable to damage.
8s there any real advantage in the truck, when we air down the tires for trails?
Yes, reducing the tire pressure is actually the best way to improve the performance of your vehicle, when you are driving off road.
9Is there any scenario within which I should not reduce tire pressure, when going off road?
Yes, do not reduce the pressure of your tires off road, if you are working with half inch tires. This is because the bead that is found in tires of these sizes are not deep enough to keep the tire on, under reduced pressure, on off road conditions.
10How does the ‘All-Terrain’ tread really work?
This tread is designed to handle most terrains with ease. It performs well on rocks and sand and on highways. It can get a bit noisy on the streets, though.
11Are mud tires good for rain, too?
No, mud tires are only for mud. In the rain, on streets and highways, mud tires give the worst performance. You will also find that they get way too noisy.
12How wide is the contact area of the tire?
This is about six square inches, at any given time. It is this six square inch measurement that is responsible for keeping your entire vehicle in control.
13Is sipping a good way to increase traction?
Yes, it is. Sipping allows the tires to run much cooler. It also increases tire durability by 15-20%. This is a very cost effective method of increasing traction, especially in conditions such as snow and ice.
14How does the inflation level of the tires affect my vehicle?
It is important that your tires are adequately inflated. If your tires are underinflated, then this will affect the engine because the engine will have to work harder, in order to keep the vehicle moving. Tires that are not adequately inflated also wear much easier and faster. They also affect the overall handling of the truck, as well as how effective the steering of the truck will be.
15What is the best way to rotate tires? Side to side, or front to back?
This really depends on the type of tires. If you are using radial tires, then from side to side will be good. However, if you are using bias ply tires, then the best way to go would be from front to back.
16Why is it that when the tires are not fully inflated, they were easily?
This is because, when the tires of your truck are under inflated, this causes too much of the surface area to be touching the road. When this happens, the tires wear down much quicker, as there is too much friction and heat being produced, between the tire and the road.
17While driving, is it possible to tell that the pressure of my tires is too low?
Yes, this is quite possible. If you hear a squealing sound coming from your tires, when you are driving around a corner, this is indicative of the tire pressure being too low.
18How much pressure can a tire loose, without looking flat?
It is possible for a tire to lose up to half of its total pressure and still not appear to be flat.
19Is there a standard rate at which I should expect my tires to lose air?
There is really no ‘standard rate’. However, tires generally lose air at around a pound each month.
20Can under-inflation cut gas mileage?
In fact, it can. Under-inflation of your tires, by about 6 psi, can cut your gas mileage by up to 3%.
21Can the temperature affect my tires?
Yes, the temperature can affect your tires. The pressure of the tires is affected by the temperature. Your tire loses a pound, for every drop of ten degrees in the temperature.
22How can I know if I am buying the right tire for my vehicle?
Aside from knowing the size that you use, you can bear in mind that it is never a good idea to buy tires that have a lower speed rating or a lower load index, than the tires that were originally on the vehicle.
23How can I find the true measurement of tires that I am buying?
To find the true measurement of tires, you can mark the bottom of the tire and make a single revolution then you measure and divide the distance by pi (3.14, or 22/7).
24Does pressure reduction work in snow or ice?
No, never reduce the pressure in your tires, to increase traction, when you have to deal with snow, or ice. It does not work.
25Is it ok to have different tires on the front, from on the back?
No, this is not ok. Your tires should match, as this will affect the way you are able to handle the vehicle.
26Is it important to rotate tires? If so, why?
Yes, rotating your tires can be very helpful. Here’s the thing. Each tire on your vehicle supports a different weight and as such, when you rotate them, you are changing the weight that they will be supporting. When this happens, the tires take a longer time to wear down and in effect, you can lengthen the tire life.
27History of tires
1493-1495 - Discovery of rubber by Christopher Columbus.
1770 - Application of rubber for erasers and waterproof clothing.
1839 - Discovery of a rubber vulcanization method by Goodyear(USA).
1885 - Invention of the 4-stroke petrol engine by Daimler (Germany).
1888 - Invention of the pneumatic tire by J.B. Dunlop(UK).
1896 - Fixing of tires to automobile wheels first began.
28Street tires
Street tires are specially designed to handle street conditions. The tread patterns in the treading of street tires allows the tires to expel water that the tire comes in contact with. This prevents water from building up between the tires and the road surface. When water builds up between the tires and the street, this reduces the traction and may cause the vehicle to not respond readily to the control inputs of the driver.The deeper the grooves in the treading the better the rainy weather performance. Tires that are intended for dry weather use, usually have relatively shallower grooves. This feature provides more contact with the road surface.
29Off road tires
Off road tires are designed for terrain that is more difficult to manage. As a result of this the patterns that are on the treading, are more like individual projections. Something like studs. These patterns help the vehicle to remain manageable in terrain that is muddy or rocky, conditions that are not regular road conditions.These individual notches allow the tire to grip into the terrain, whether it is mud, or otherwise and this helps the driver to maintain control of the vehicle and it prevents the vehicle from getting stuck, especially when it comes to the muddier terrains. When used on asphalt, off road tires will wear down very quickly. This is due to the fact that they have much less contact area to the surface, which is very well suited for off road expeditions.
