The Short Answer

Tanks are heavy artillery. They don't need to be particularly close, in fact it might be better if they are out of the range of sight entirely, given that you can perform parabolic bombardment. As a result, high mobility isn't required — just enough to make it competitive with conventional vehicles like trucks. You're never going to outrun a plane and the average non-tank vehicle is a trivial threat, so there isn't a need for much more than this. When they do require long distance travel, odds are it would be more efficient to transport them by rail or plane, given how much work they need to be restored to fighting shape. Furthermore, tanks require a ton of maintenance — not as much as a fighter jet, which can take as much as 30 hours of crew time per hour of flight time — but substantial. Faster/further travel would only cause more wear and tear, and battlefield logistics suggests that minimal bursts of action, followed by minimal down time, would be the most effective use of tanks.
