You would think at that low psi it would drive the rim into the ground making the tire oval,then unload on extension with the radial sidewall.You may have to change launch rpm and clutch settings and tighten the shocks for less "hit' to get it off the line clean.It would be more of a challenge on a higher HP combo. gsa612
