Wow, finally, I understand it - to a minimal extent of course.

So 30 profile just means low profile in general terms?
Yes, take the size 255/35/19

255 is the width of the tire

35 is the amount of rubber between the rim and road (profile)

19 is the rim diameter

30 profile is less rubber between the road and the rim than 35, which unless the roads in your state are in awesome condition is not a good idea. Potholes eat 30 profile tires and the rims they are mounted too for breakfast.
