Re: What size tires are you running (p0cket penguins)
Most of the summer only tires for the 18" pegs are already low profile. Almost any of them will look less thick in the sidewall as compared to the stock pirellis. I wouldn't go with a very low profile tire do to the peg's susceptibility to denting since they are so soft. This is a quick way to a bent rim or worse. If you want a lower profile, change the rim as well.
