Best tyre profile for 1/4 mile drag

[salmanghiyas]

Well .. as i have both rims ... I am getting confused on tyre profile ...

I have 16" Lenso LS GT
And
15" OZ racing

I tried KUMHO 205/50/16 tyres on my Lenso .. they were good at launch but i lost few races just because of the lower top end ...

I wont mind a lil spin on launch .. all i want is a good top end + good launch

Good top end comes from taller tires. Good launch comes from short and wide tires, very light wheels, or a significant increase in power (nitrous, turbo, supercharger, etc.). The only way around that is to use the kind of tires that real drag race machines use: they're wide and short on launch, but flex and become skinny and tall as the car gets up to speed. The other thing to keep in mind, is that you're running a Yaris. Without significant investment, you're not going to get much faster than 15s or so.
