If the tire pressure is the same you will have the same total contact area
for four tires as you would with eight tires, again the number of tires
doesn't matter. The number of tires determines the load carrying capacity of
the vehicle. If this is wrong, show me some numbers and I'll be quiet.
Cheers,
Bjorn
