Default Versus....

What are the advantages and disadvantages of big tires (front and back), and also for small tires (front and back).



ie: iRazr


Back Front

20 x 11-9 21 x7-10

20 x 11-10 22 x 7-10

...where's brad when you need him...

Let's review:

Tire designation: 20x11-9

20" diameter
11" width
9" rim diamter


Rim Diameter - A taller rim leaves you with less sidewall and will corner better and more predictably than a shorter one. But with less sidewall you have less protection for your rims and tires, which can leave wheel dents or even pop tires if you hit an object the right way. They will also provide a slighty softer ride, again because of sidewall height.

Tire height - Taller tires provide more ground clearance and lower the gear ratio yielding more speed up top. A taller tire will have more sidewall than a shorter one with any given rim size. That means you'll have more protection and a cushier ride with a 10" rim on a 22" tire than you would on a 10" rim on a 20" tire. But a taller tire will also raise your center of gravity making the quad tippier and put more strain on your clutch. The increased size and weight also reduces effective hp.

Tire width - wider tires will have better floatation and typically a flatter profile. Wider rears will slide better and provide more surface for traction but adversely effect power and can spread weight out too much for traction in slippery terrain. Wider fronts will again provide better floatation and facilitate wide, sweeping, sliding turns like on a flattrack. But skinnier tires will carve and turn better and lessen the chance that you'll clip a tree, root, or other obstruction.

If other's would like to add to, disagree with, or otherwise comment on my post feel free to. I'm tired and may have allowed something to slip or left something important out.
