Question about discount and tracks

Is the discount for Spintires owners only valid when purchased MudRunner through Steam?
And secondly (surely someone already asked about it, but I deserve to know before buy) Will there be tracked vehicles such as bulldozers. Because if not, I do not see a bit of sense in buying the same game. Regards.

tracks are planned for the future, they will not come out upon release. Go read.....

Hey. Thanks for the answer. Where did you find this information? I do not have time to search the whole internet for all the information. That's why I ask here. Regards.
