Will these tires Fit?

[vipereater]

I am wondering if these nittos will fit my Z06?
they are 305/45 R18

also does anyone else have these?

do you run them on the street?

How do they do 60ft times?

thanks

I believe they will (might) physically fit. IMO that tire is way to tall.
The stock tire has a diameter of 26.1 the 305/45/18 has a diameter of 28.8 (That's huge). That would be like going from the stock gear ratio of 3.42 to a 3.07 gear ratio if my math is close to being correct. Which is going back-wards if your making the change for performance reasons. Also the sidewall height will be 1.3 inches taller and it will look strange (funny). A better choice would be BFG DR's in 315/30/18.

I'm curious as to these tires being ok with a 3.90 rear? I have read in other posts that if you go up in the rear end ratio, you should get a taller tire. I wonder if these would throw any codes by keeping the stock diameter front tire and having these taller tires on the rear?

anybody have any thoughts or opinions?

In terms of codes I am unsure - but you would certainly get a bigger contact patch to the pavement with a taller tire. Most drag guys go with a taller tire and more gear for the best traction and quick acceleration/60ft times.


With the 3:90s you may need more tire to hook.

That tall of a tire will change your 3.90's to a effective ratio in the 3.60's range

If im not mistaken, these are made for the Ford Lightning and will NOT fit.

Been there, done that.
