I would imagine that on a car as light as the Insight, the difference in price is going to be bigger than the difference in rolling resistance (though with the amount of distance you drive, wear is also a factor).

This is NOT a problem one would ever have in a Mirage.



Interestingly, just before I sold the $800 Fit, I broke the inside tire loose on an uphill left turn from a stop. It was unintended... but I let it spin merrily away until the 1-2 shift just for fun.

Also neat that you're running the same 185 F 165 R tire width combo as I am on the Mirage. (Which I'm doing solely for the gearing change).

There's also a lot more tire selection in that size!

14's in general are becoming scarce.

Why did wheel sizes increase? If larger is better, why didn't manufacturers simply start from a larger wheel?

Hmmm...bigger wheels have less centripetal force on the tire since they rotate slower at a given speed, so the tire can be made weaker in tension. I suppose the tread flexes a bit less reducing energy consumption and improves grip a little. Finally, I think customers think big wheels look cool, because wheels have been getting bigger and bigger while the tire sidewalls have been getting smaller and smaller.

I'm guessing it didn't start that way because they didn't want to spend money making big wheels when a small wheel would do. Unfortunately, tires for small diameter wheels are getting harder and harder to find, so we'll all be switching to big wheels at some point :/

More of the population lived where the roads were poor? It is really easy to ruin a low profile tire/rim on bad roads.

Suspension has gotten better? A tire with less sidewall depth generally rides harsher. There was a time when Americans wanted comfort over performance.

The real reason probably has to do with aesthetics. People want big rims with low profile rubber and huge disk brakes to look like a race car.

Hopefully the tires get here soon. I'm starting to lose pieces due to... erm, hypermiling.
