I'm confused.... if the idea of the 16/19 conversion is to eliminate the rear over drive and make the front and rear to spin at the same speed, why do you need to run a smaller tire??

you have to buy the pulley set for mtx-3 to do the conversion and also the 16/19 conversion side belt because once you change the pulleys to 16/19, the stock belt won't fit anymore.
Aaaaaah ... thats all to it. Well, my LHS sells foams in sets of 3s. Now with even wear then I will have to ask him to sell in sets of even numbers! Hahahahaaa ... I think I can live with the current pulleys.

The 16/19 conversion does not eliminate rear overdrive. Front overdrive rather.

By default, using 16/19 conversion makes the front wheels rotate at a higher rate than the rear. Hence if you use same front and rear tires, you get front overdrive i.e. front pulling the rear. Front tire rollout is bigger than rear. Sometimes this is desireable on certain tracks but sometimes not.

Therefore to make the front tire rollout the same as the rear tire rollout (i.e. 1:1 overdrive), the front tire needs to be smaller.

The 16/19 pulley conversion does not just give you equal front and rear wear. Firstly, it gives you the choice of running big tires in the rear to attain sufficient tire rollout to achieve a certain top speed while being able to run smaller tires in front.

Smaller front tires gives you better steering because smaller front tires let the front part sit lower and the car transitions better left to right. Smaller front tires also eliminate traction roll.

So the rear wearing down is fixed by running the 16/19 setup but in turn you still lose foam due to having to run the front 4mm smaller. I understand the performance difference but I doubt its a good selling point to some people who would rather not purchase a tire truer, or lose foam before the car hits the ground.

Trust me, a lot will agree that you'll have more fun when you discover things like this that will improve driving and handling of the car.

What fun are we talking about when you have to true the tires to make it work, also none of the Mugen drivers are really using it at all whilst they kick ass ...

I agree with what you say but I think you should refer to the MTX-3 thread first before you make a sweeping statement like none of the Mugen drivers are using it...

At low speeds, it works like a regular gear diff. At high speeds it locks and works like a solid axle.

I use it, and I can be VERY competitive and still have fun. Like everything else dealing with these cars, it's all personal preference. What works for some may not work for others. Truing tires is not a big deal (for me anyway), because I have to true my MRX-3 tires regardless. What's a few pair of TC tires? Another 10 minutes? I realize some people have a problem with taking rubber off brand new tires, but in the long run, you actually get more run time out of them provided your car is properly setup and you stay off the boards. JMHO.
