Anyone know how 18x30 tyre height/circumfrence compares with say 13x38 or 18x34?

Brands are different. It can take a while to dig through and search, but tire companies have much of that info. on their websites. When you finally find the spec's. ,you can get lots of info- recommended rim, loaded radius, flat plate(foot print) etc. etc.
