255/45/18 & 275/40/18... ?

PS - After you push the period button when completing a sentence, you usually follow that up by pushing the space button, not the enter/return button. Unless the above was your weak attempt at writing an Haiku.

P.S. Another failed attempt... I believe it should be "a haiku." Not "an Haiku." Using "an" is usually followed by a word that begins with a vowel. So now we know that you aren't any good at Math or English.

Currently there is no ultra high performance summer street tire that runs thicker than 285 for the 18" rims. You must have a 9.5 x18 rim in rear to properly run the 285/40-18's.
There are the R-compound tires you can fit a 305/40-18R in the rear, it will have a 27.7 or so height, and not be safe in the rain.
The bummer is when you look at the Viper, the Z-06 or the current ZR-1, or Porsche, they all are able to maximize their power with 325-335 wide rear rubber. In 70 degree weather, no 285 wide summer tire can handle 550hp (475rwhp), so the frustrating part is how much better those super cars can put down their 500-635HP with correctly engineered tires for those vehicle weights and HP outputs.
305 is the widest we can go(without race cofigurations) on our cars at 18" wheels, so our cars do not have near the low gear street speed of the above mentioned cars. Erik
