Tire/Wheel n00b - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hello All!

I know next to nothing about tires/wheels. If you would bear with me, would you mind answering a couple questions?

What is the stock tire/wheel size on the FR-S?

What does this combination of numbers/letters mean?

How do I choose the right tire?

If I want to put a specific tire on a specific wheel, how do I know it will fit?

What else would you consider "basic information" about tires/wheels that someone should know in order to be at least marginally educated about it?

Thanks for putting up with a novice!

17x7" wheel. 215/45R17 tire.

What, the tire size? 215 = section width in mm. 45 = aspect ratio, meaning ratio of sidewall to section width. R = radial (all modern tires are radials). 17 = wheel diameter.

Um...can't answer that easily. Google?

Check the manufacturer's suggest wheel size for a specific tire size. Like this. Click the "specs" tab.
