I'm pretty sure this is a re-post.

multi re-post. Also their 18" test is completely invalid.

I must have missed that, why was it invalid? I think it should have been compared to the same rim in 17". 18" was still faster than oem (though light). I think the lesson was "don't skimp on tires."

Because the tire they chose was 1" taller than stock which would have lengthened the gearing and slowed acceleration. So we can't be sure if the mediocre time was due to the weight of the larger tire or the much larger diameter.

Regardless, more and better rubber is always a good thing as long as you don't have to screw up your suspension to get the tire to fit.
