Right now I currently have a set of wheels and tires I bought from American Muscle it's The staggered fitment of 18s 285/35/18r I am wondering if I can fit a 305/45/18r if anyone can help that would be great

 

I think they would. But go here http://www.discounttire.com/dtcs/infoTireMath.do
and check it out.

 

Every tire manufacturer has a rim fitment chart. As long as your rim size is in the given range you're good. Now there are some folks out there who will fit any tire on any rim and think it's OK but it usually looks stupid and is detrimental to performance. Stick to what the tire manufacturer suggests.

I run 305/45/18's on my car.

 

I'm pretty sure I'm gonna go with nitto nt05 drag radial 305/45r18

 

Those are pretty decent tires. I ran them along with the triple 5R's and MT's. They are right in the middle as far as performance. They don't last for **** though, but either do the MT's.

 

that looks great thanks

 

is yours lowered at all or is it stock height

 

How wide are the wheels?

I have 9.5"-wide wheels and I'm running 305/40/18's right now, Nitto NT555R:






I had 18x10 on the car for a short while, with the same tires on them, and they fit even better:

 

18 x 10 is what I have

 

Those pics are with ProKit springs. I ride on Cobra Jet RA springs now which is a little taller in the rear and a little shorter in the front.



I'm thinking those are just a tad wide for a 9.5" rim. It might be better if you had a bit more sidewall height. Maybe try the 45 series next go around. The bulge will be less noticeable.
