I have a 1990 miata putting down over 200 wheel hp. My 195 toyo t1-s arent cutting it. I auto-x a lot and i also drag race, with intention of road racing in the near future. I know i cant have 1 tire for all 3 forms of racing, but which one would be a better bang for the buck tire? Obviousely the V710's would stick better, but would they realy be worth it? I plan on buying Team Dynamics 14x7 with either 225/50-14 v710's or the toyos RA-1's in the same size. I know the RA-1's are very good track tire, but are they THAT bad for auto-x? They both have a hard sidewall but would the 225 ra-1 be a decent tire to get me under 2.0 60' time? I would like to get the best bang for the buck tire and i need some more advice. Once again im not trying to set records i just want to step up the fun.
