I hope most of you are smarter than I; but just in case

I guess I don't understand the manufacturers desire to equip cars these days with low profile tires. They subject the rims to easy curb damage and both the tires and rims to frequent pothole damage. Also those tires are more expensive to replace when worn out than the earlier normal 15" or 16" rim size tires.

Rim sizes exceeding 18" also cause a more stiff ride - all in exchange for the supposed sexy look of those taller rim sizes.
