A lot of track guys run 180's cause they're cheaper and more common.
Typically a 180 fits on a 5-1/2 inch rim. Our rims are 6 inch. But then again, I've seen manufacturer rec's for a 180/55 to be mounted on either rim width.
A lot of us on this forum run a 190/55 for our street RC51's. They're great on a track too.
Stock size is 190/50-17.
The 55 series is a taller tire with a bigger contact patch at lean angles, and makes tipping into a turn easier and quicker.

190/55 is a great size, thats what I run. Ive never run a 180/55 but it looks very similar, but like jondog said, the rim size is more conducive to a 190 width. All the cool kids run 190/55!

JD is right, most people that mount the 180/55 do it to save money because they go through tires much faster at the track. It gives you a taller profile for a slightly cheaper price, but I think the overall contact patch is not as big the 190/55.

For regular riding the stock 190/50 is fine. I'm still running 190/50 on my SP2 even at the track (since the tires were new and I didn't feel like spending the money right away to change) and I have no problems. Next summer when I need to replace I will go back to a 190/55.

Some people even run a 200 size.

200 is stock on a HP4 (not an RC I know)...but just saying that there are different combinations on what you want to do based on your riding style.
