It's a cool idea, but that tire size doesn't seem to exist.

The NANKANG 165/80R15 is rated for 44 psi I'd probably get those , I got Kumho Power Star 165/80R15 tires last time from Tire Rack, 35 psi, not very good in snow. The Federal 165/80R15 SS 657 is rated for 35 psi. You car will coast far with this tire size.

What are we doing different? I get no tires available in the size I select when I put in 165/80-15 tire size at Tire Rack and 1010tires.com. I also get no hits at Tire Rack for Kumho Power Star tires. Are you smoking funny cigarettes? Are these some weird trailer tire size, or something?

Just be aware of the fact that the type of tire (meaning make and model) may have a pretty large effect on your results.

You'll also be changing tire size which will also have an effect. Not to mention removing worn out tires and replacing with new. So there are 3 variables just in tires. Be careful when you report the results that you don't identify a single item as the change in mpg!

Tire Rack no longer carries the size. Try Googleing 165/80R15. You might find some used ones on Ebay or Craigslist.

185/65R15 vs 165/80R15:

I took a hand grinder and cut tread blocks in the tire.



rolling resistance of 165/80R15 at 42 psi and 35F:
