I think you should use a car that isnt a monster truck if you just want high speed. Why are people obsessed with forcing things to do stuff theyre not meant to?
I mean its not like running a MM out of spec (ie getting more for your money kind of thing...) its just plain silly.
To each their own I guess. I'd say go with some street tyres and balance and strap them really well to stop any wobbles or balooning.
