Best tyre profile for 1/4 mile drag

[salmanghiyas]

Hello guys ...

I own a 2008 yaris 1.5L manual tranny ...

Current mods are :

1zz tb
1zz IM
Blitz SRI
Custom made aftermarket headers
Custom made 2.25" straight down pipe

Kindly suggest the best 1/4 mile drag race tyres and profile ...

In both 16" and 15" .. i have both sets

Are your current tires spinning on launch?

When I had my 09 supercharged, it was very easy to spin when launching with stock tires, so I upgraded to 205 width Nitto Neogens. Even prior to being supercharged, I could break the stock tires loose if I really tried (or if the pavement was at all wet). Now that I am no longer supercharged, but still have the Neogens, I can't break them loose unless the pavement is super slick.

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.

The smaller the better in overall diameter. Less weight and size means more power to the ground.
