Yeah thats the truth. If we leave at anything over 12psi we seem to just blow off the tyres. On the flip side if you pull too much boost out it just lays over.
We tried going taller on the tyres - 29.5x10.5 MTs, but it didnt really do the job. We had the soft wall slicks and the car just seemed too heavy for them on the kind of boost you needed to run to get them to hook up. We ran the 8.7 on those, but it was very sketchy at the end of the track at speed.
