Terra Grapplers are the s??t, ive put some serios miles on them. I run them at 45 psi on the road, the only problem I have is hard braking which causes a little front sway but I can deal with it. Off road I run 15 to 20 psi. Plus the reason I bought it isnt for the road only, as long it performs off road who cares, and if you care sell it, you dont deserve it and your VX is very sad and misserable because it dosnt have a scratch. Scars are cool.
