What is the difference between a 2.2 and a 2.8 inch tire? Is there a speed difference? Handling difference? Or traction difference?

Does it lower your ride height?

About .6

There should theoretically be a speed difference. Since the tire's diameter is larger, its circumference is therefore larger as well, giving you more ground distance per revolution of the wheels. This may, however, be slightly mitigated by the fact that a larger wheel has more mass that needs turning. But essentially, yes, you could achieve higher speeds with 2.8s over 2.2s.

Going back to circumference/diameter, a larger wheel when squished to the ground should have more surface in contact, in turn giving it more traction. Keep in mind that tire width will also affect traction.

Handling might be a bit finicky since there are so many variables to account for, including the fact that there will be more weight above the axles from the larger wheels.

So basicly no difference exept 2.2 inch has much more selection

If that's how you'd like to interpret the information, then sure
And as for your second comment question, 2.8s will make the ride height about .3" taller depending on the tire's outer diameter (half of diameter = radius).

Does it matter if I get 2.2 wheeles in back and stock 2.6 wheeles in front?

It might look a bit weird but as long as you're running a 2wd car it shouldn't really matter I guess.

If you want the larger diameter wheel (for less sidewall flex) afforded by the 2.8s but the tread and compound selection of the 2.2s, it is possible to modify 2.2 tires to fit on the Traxxas 2.8 wheels (but not the Proline 2.8s without also modifying the wheel). I did this so I could run 2.2 treads on a Slash 4X4 which is not compatible with 2.2 wheels in the front.

sorry to bring back an old thread, but a what if the 2.2 and 2.8 tires have the same outer diameter? are there any advantages or disadvantages to either or? I was planning on putting 2.2 rpm revolvers with 2.2 dirt hawgs or dirt works, and the outer diameter of the tires appear to be the same as the stock 2.8 tires on my rustler.

And so it rises from the dead...
For off-road, you'll benefit from having higher profile tires, i.e. the 2.2s, because they'll absorb more bumps and jumps. For on-road, the 2.8s will give you some benefits from being significantly lower profile, so they'll be less prone to rolling the sidewall over in turns.

that was what i was assuming. i just wanted to get affirmation from someone who knew what they were talking about. thanks!
