I can hit 120 in the top of 4th right now with my mods and 4.08s , So i go through in 4th gear...

I can get 305/35/18 MT ET street radials

OR

Nitto NT05R radials in 305/45/18

MT's are shorter than stock diameter by about an inch...

Nittos are taller by about an inch....

So one would raise my gear ratio and one would lower it... Im confused as to which would do what... I believe the taller tire would lower my gear ratio down to 3.9x , and the smaller one would raise it , correct?

Which one should I order??

gonna PM this to jNaut the king of all 1/4 mile stuff as well, lol...

thanks fella's
