Also if your MTX3 has 1 to 1 drive, the smaller the rear tire, the more front drive. The front one way compensates for the difference.

In a way... The one way front allows you to run overdrive. Off power, the front wheels will get to roll freely and detaches from the rear wheels unlike a front diff where it will drag the drivetrain if your front and rear tire sizes are different.

On power, one of the inner wheels of the front one way will also lock and pull the car nicely in a corner unlike a car with a front diff. With a front diff, the inner wheel slips on power and therefore does not provide the overdrive effect to the fullest. That defeats the purpose of running an overdrive in the first place.

I'm glad to read that you fully understand what happens to the car's geometry as the tire wears down and what settings of the car changes. Don't worry. As time goes by, I'm sure with your understanding of things, you'll find the correct tire size for your car.

Frankly speaking sometimes i have no idea what you are talking about.
Overdrive has to do with gearing and not one-way. A front diff will also allow you to have an overdrive..

Read slowly and you'll understand

A front one way will allow you to run overdrive efficiently. You can run front overdrive with a car equipped with a front diff.

However, there are some drawbacks when doing that. That is what I explained in my previous post that front overdrive with a front diff will not work as effective as a front overdrive with a one way front.

Thanks InitialD
Just another question....when an optimum diameter combo is achieved, will the tires wear more evenly from front to rear, or will the rears continue to get progressively smaller as compared to the fronts?

I honestly do not know the answer to that. My guess is that the rear tires will continue to get progressively smaller than the front even if you started out with optimal tire diameters. Perhaps somebody else can chip in?

Overdrive has to do with gearings.

It has nuthing to do with one-ways or diffs..
what you had mentioned is Driving an overdrive with one-way or front diff..

get it?

Well, what do I know? I guess I must be wrong then since you seem to say that I do not understand what I'm saying I get nowhere and no kick from doing this...

Basically the rear tyres will get progressive smaller than the front because of the shift of weight of the car to the back when running in the forward motion and during accelerations.

Even if the front and rear rollout ratio is equal, you will still get this wear because of the shift in weight.
