16" Tire Sizes

[Low Level E30]

What are the correct tire sizes for each of the following tire widths, on 16" wheels:

205mm

215mm

225mm

Thanks!

205 = 50
215 = 45
225 = 45

With the closest being 215/45 R16 for matching to stock rolling diameter

Thanks for the help!

Looks like 205/50 will be the choice, as they will run on 7" wide rims.

215/45's are far and few between. And 225's look fat only a rim that's only 7" wide.

Actually 225/45-16 is closer.

Overall diameters according to http://www.miata.net/garage/tirecalc.html:

195/65-14(stock non-M, non-ix size) : 24.0"
205/50-16 : 24.1"
215/45-16 : 23.6"
225/45-16 : 24.0"

Other popular e30 sizes and diameters:
205/55-15 : 23.9"
225/50-15 : 23.9"
215/40-17 : 23.8"
245/35-17 : 23.8"
215/35-18 : 23.9"
285/30-18 :evil: : 24.7"

actually 225/45 16 is the closest to stock rolling diameter. 215/45 is the furthest per http://www.miata.net/garage/tirecalc.html if you take stock rolling diameter to be 195/65 14.

But 205/50 16 is close enough. That's what I run on my 16x7 wheels.

Damn, I was too slow. Great minds think alike, you know.

Those tire diameters you listed should be stickied. Good to know.
