rims tires compared to stock tires

to take advantage of that extra contact surface!

Seriously, why go half way? Go full circle and build a real car.

There shouldn't be a problem w/ balancing the tires.  Might be more dificult for the tire place and they might charge you more but they should be able to do it.  And yeah NowYaKnow probably right w/ the brakes.  Upgrade them.  It's a kinda complicated physics explination of eqations.  Also it lookes kinda retarded if you have huge rims and little dinky stock disk/drum breaks inside that are like 1/4 the size of the rims.

Actually a larger contact surface would mean easier braking b/c there is more area of the nonmoving group of particles trying to resist motion compared to a smaller tire w/ less contact surface, therefore less area for the nonmoving object to grip. 

But let's say you have ABS.  Then bravo to Ravendarat.  The 22" has more mass then the stock (let's say 16").  And a 22" rim has a greater rotational velocity at it's edge.  Greater mass, greater velocity all equal a greater momentum.  Greater momentum means you need a greater force counteracting the momentum (a bigger brake).  Gotta love physics and dynamics.

I was just thinking about this today...

larger rims don't always wiegh much more than stock rims. Some can be very light, I'm assuming these rims are lightwieght, otherwise what's the point?

The problem most likely comes form the majority of the wieght being further away from the center, having stronger momentum against the brakes. I'm no physics expert, but I relate this to using a breaker bar over a stubby wrench, which is easier to turn?

A few good reasons to upgrade the brakes, most have been mentioned:

1. Don't expose weakness......showing off stock drums and rotors with large rims is uncool....it looks like you spent all of your money on rims and ran out of steam. It also looks like the car is trying to be something it can't be, because it can't.

2. Stock brakes suck anyways....at least upgrade the pads and hoses (steel braid)

3. the rims will be harder on the brakes, enter formulas for rotational force here:

I have a whole book of this from NEMA, it's an engineering pocket book, it's fascinating!

4. These tires will have better hanfling, braking and handling go hand in hand...otherwise there is an unbalance in performance.

5. Safety, don't you want to know your car will stop when and where you want it to stop?

Just think, if you encountered a deer, multi car pile-up at 70 mph, stupid drivers, drunk drivers running red lights...ect.. would you be able to stop?

6. Deceleration can be just as much fun as acceleration......once and a while :D

Came here to talk car audio got a physics lesson.

But they are right...( A little math for you) Big Rims +  Small brakes = No stopping power...
