For this, you have to put a special plate on the bottom of yout car. For it to work, you need to cut the end off a white rod, so it won't hit the crossties. This works best with multiple car trains.
I'm working on a spiral lift using this method.

What I mean is, if they were spaced a "whole-numbered" car length, the tires would eventually stop where the spaces are between the cars. During the whole duration of the trip up the hill, there obviously needs to be at least one tire pushing the train up.
Say, for instance, at the bottom of the lift, there is one tire on a piece of flat track and one on the transition upward. The first tire probably won't get the train stuck because there is still momentum in the train to push it to the next tire. But the second the train gets to the second tire, momentum is lost, which makes placement of this tire good.
Once the first car of the train clears the second tire, the second car is still being pushed by the first tire. This tire will push the second car (which obviously in turn pushes the train as a whole) enough so that the first car can reach the third tire, and so on.
Having four cars is actually very good. While you may have to sacrifice lift slope and speed, you will always have two tires pushing at the same time.
EDIT: Honestly, I would recommend this method for large lifts, unless you have a lot of tires. To break the math done more simply, the distance between tires has to be the highest "half number" less than half the number of cars in the train.
Also, your first tire must be either on a flat surface, downward-sloping surface, or have enough momentum to make it to the second tire.

If you want to use this on an invert, you need to put a blue spacer between the bottom of the car, and the first yellow connector (on the white rod).

I have built a tire drive myself and it's at the same height compared to the track.
Now Zapa came up with sawing a white rod to make it work.
What I did was taking a blue rod and snapping 2 black clips on it. They have to be on the outside, just a little to the center.
Then you turn your car upside down and click the black clips into the front row of the car and voila, the blue rod helps the train being pushed forward.

I like Jogumpies better, it looks more organized and neat.
