Thank you for that article, where the 3 main takeaways are...

"If the wheel diameter increases by one inch, the height of the tire
should decrease accordingly to compensate, in order to keep the overall
diameter the same."

"With larger wheels and lower profile tires ¡X and the resultant shorter
sidewalls ¡X they¡¦re stiffer and there¡¦s less of an air and rubber cushion
than before, increasing the chances that hitting a large pothole could
damage the tire, wheel or both."

"An 18-inch tire, for example, will probably weigh at least a couple of
pounds more than a 16- or 17-inch tire. That could also be true of a larger
wheel."

To summarize what the article said for moving to larger-diameter wheels...
+ The overall vehicle suspension remains at the same ride height
+ Tire air "cushioning" is greatly reduced
+ Unsprung weight goes up appreciably


I found it interesting and first sentence says it, "They look cool."
