Road & Track: 5 minutes to a faster FRS (/BRZ) via Tires
 

Road and track did a tire test on the FR-S, comparing the following:

Stock wheels/tires
Stock wheels/215/45/17 Dunlop Star Specs
235/40/18 Star Specs.

The results were interesting, take a look.

recap for people who cant watch youtube at work?

Buy tires.

Stock tires not grippy

Starspecs in OEM size are grippy

Starspecs in larger size are slower than OEM starspecs


All of this should be no surprise to people who understand contact patches and all that stuff. Wider/larger is not always better.

(unless you address the entire system)

nice, although pretty much what i figured.

Still informative for the people that are not aware though I guess.

yeah but that video barely explains it, there is like 10 seconds of technical information in that video

i am dissapoint.

No lie, this is probably the most repeated thread topic. And it really isn't worth anything since the tests they perform aren't worth anything.

Sorry, fellas.

next time it's your finger.

I just like the fact that an "underpowered" car with proper summer tires beat out 2 turbocharged 4 bangers, for both of which I hold a great deal of respect.

Would have liked for them to do a 235/40/17 as part of the test.

Just did a little bit of research and found that the DW weighs about ~27lbs and the OEM tires weigh about ~20lbs. Does anybody know how much of an effect this has on fuel efficiency?
