Make it handle

My rear wheels are 22 x 12 with 7" of backspace. My question is having the front and rear track width the same good for handling or does it not matter?

Yes, typically, we want a "square" truck. Really, we are talking about the Track width (center of tire to center of tire), not Tread width (outside to tire tread to outside of tire tread) So at 59" front and back you are pretty close.

We used to think we could improve the trucks by making the front track a little wider than the rear, to eliminate the push. It works to a point. But, with better tires over the last 10 years, stability is less of a factor. And, the end (front or rear) that is wider gets less mechanical tire loading. In the end, the 'wider' end will loose grip (all else being perfect) first. So, Square is the rule.
