Hi.

I need some help choosing drag tyres for my car. and want to do it right the first time..

The car have gone 11.01-140 with a 60" of 2.12 on street tyres ( spinnig tru 2 gear) on street tyres ( 90'F day) 3200lbs

The tyres i was using was 23" high, and i was 100rpm under the rev limit in 4`th at the end. so tyre size might be a little to small for next season ( about 30hp more)

The tyres i am choosing from is:

BFG g-force drag 225/45-17 ( 25" hight)
Nitto nt555r 245/50-16 ( 25.65")
Hoosier qtp 26/9.5-16 ( 26" ) ( how much does these expand? not 100% shure i have room for them)

Hoosier DOT drag radial 225/50-16 ( 24.8" )

( reason why i included the hight is because i`m not shure how much it will effect my time since it will give me longer gear. ( max hp is close to rev limit)

So my question is: witch tyre will be fastest? is the g.force tyre faster than the nitto tyres even is it`s thinner?
Anything else i need to think about?

Just had to ask here since you guys seem to know what you are doing when it comes to drag racing 4wd cars..

 

Spell check could be your best friend

Try it next time

I'll understand if your outside of the US.

 

I think he is from the UK or Australia because of the way he spelled "tyre."

 

Go with the hoosier qtps no doubt, drag radials are just parts breakers..

 

I personally like the Drag radials Hoosier man.

 

Yeah they are good, but the sidewall is to stiff if you need a tire for strictly for drag racing. The bias ply qtp is much easier on the drivetrain.

 

Sorry, but i`m trying the best i can.
I`m from sweden, so this is not my main language.

But how much will the taller gearing affect my 60"\trap\et?
My guess is that a 24" tire will give me about 100rpm under the rev limit.
So my guess is that i should get a tire that is about 24" tall.

But the tire i guess will give me the best 60" is also the highest of them.. qtp 26"

From what i have read, the nitto tire is the one with the least greip, but is does have a better size, ( 245/50-16 compared to the other two that only is 225... )
Will the wider tire compensate for the lesser grip? or are the other tires still better?

Sorry about all the questions, but trying to learn here..

 

I ran BFG DR's on my Z. Lasted a long time and were ok to run on the street as long as it wasnt raining. Preload the drivetrain and you won't break anything.
