here check this out ,, on left 205/50/15 and on right 205/40/16
I don't have the pics of the 205/45/16 yet (b/c I have'nt taken them) lol
when I was on the 205/40/16's spinning alot on take off also I was running out of steam at the top end faster than the other guys(B14 tranny),, and when I was on the 205/50/15's we all seemed even through the gears but my take off traction was the sheit bro,,

grip from hell !!!(B14tranny)
these 205/45/16's are real close to the 50/15's on feel but my biggest problem is this B15 tranny,,, wow what a difference,,,, I can get through the gears much faster than the other guy now ,, lol
