tire help please

[red96camaro]

ok, I'm new to wheelers and just picked up a 400ex. I wanna do all types of riding with it.

I got it with what I think are insanely small tires on it which I assume are for speed. Can someone give me to rundown on quad tires and why I'd want what?

also what's this .125 and .190 all about? how do i knwo what I have?

Thanks

edit: also do you guys mount tires yourselves?

The smaller the tire, the less top speed but quicker acceleration. You will want 20" on the rear and 22" on the front.
.125, .160 and .190 are the thickness of the wheels.

what kinda wheels do u have?

i've got stock ones for front and back, stock fronts are on now but with aftermarket backs, not sure what they are and the wheeler is at my friends place, but they are 8 inchers i think

prolly 18" you prlly wanna go back with the stock 20" on the rear.
