Default which tire size for 15"

I only can use 15inch, cause I have an ITR and I want full DRAG Slick.

what would you choose?

8.5/24.5-15 M&H
8.5/26.0-15 M&H
8.0/26.0-15 Hoosier

I don't know if I can run 26inch, cause my car is lowerd, that is pretty much diameter´. Also there is an M&H 9.2/24/15, but I was told I will loose much power if I run that wide slick, it would be better when it has more diamter.

BTW: I make 375whp.

What would you chose and what rime size wuold you go with? And what compound should I go with? I have 4 or 5 DRAG races per year.

Thanks!

I would go wider before I went taller. and you don't need a 26" for 375whp. 24.5/8.5 M&H would work nice

Well I have to change just a little, Here is what I come up with. If he has a turbo he needs to go with the 9.2/24-15 now if he is a allmotor then go with the 8.5/24.5-15. John@M&H

I leaned out the 440cc with 330whp easy. You need to rin extremely hight fuel pressure right? Otherwise I can not think of running that high hp on the little injectors.
