It's very likely you would need to take into account the time to accelerate up to the speed you want, and time to decelerate to reverse, because it's still only 1/4hp or something. The energy tied up in the wheels too. You will likely need to model a spherical Moon because by the top you're doing a pretty good percentage of the minimum orbital speed.
Added on edit: you don't need a rotating spherical moon because the moon rotating slowly enough to ignore and the effect is canceled on the return trip.
As I said, you just need to lower internal pressure by one atmosphere although you could get away with more because the tires will be bearing one sixth the weight.
I didn’t show all my work but yes, available traction will limit your acceleration. My estimate was that I could increase (or decrease!) my speed by not more than 6 km/hr per second.
