Tire rack test: effect of wheel width on lap times

[usdmej]

this seems more a case of people "over tiring" their wheels more than anything else

a 245 tire on a 9" wheel is hardly "stretched"

Huh. The more you know. I’ve already been tempted to downsize from my 245/275 setup to 225/255 or 235/265 next time I’m due for tires.

Would also be curious to see some testing on different wheel diameters. Perhaps that smaller sidewall would actually be beneficial.

Not the result I would have predicted. Turns out stretched is fast.
