@arstechnica There’s a reason I replaced my GTI’s stock 18” wheels with 17” wheels… (I was planning on it anyways but then one of my tires burst from hitting a pothole like 3 days before I actually replaced them).
Car and Driver looked at this in 2010 using a Golf and multiple wheel packages:
"What’s immediately apparent from the results is that as the wheel-and-tire packages get larger and heavier, acceleration and fuel economy suffer. Neither is a huge surprise, but we measured a 10-percent drop in fuel economy and a four-percent degradation in 0-to-60-mph acceleration from the 15s to the 19s,.." https://www.caranddriver.com/features/a15130598/upsized-wheels-tires/
Tire size was actually a consideration when my wife was looking for an SUV. This was due to the exorbitant cost of tire replacement with the last SUV she had.
I see some of those prices for an ordinary SUV/truck tire and I'm thinking I could get a really good race tire for less!
@arstechnica You mean back to smaller rims and higher profile tires? Yes please. Sure, it hurts handling but you know what really demolishes any gains low profile tires give? City traffic.
