Stock rolling Diameter on wheels?

Post by cjthor »

For some reason I cant find this anywhere...Looking to get a set of slicks for 15 inch wheels and need to know the OE rolling diameter so I can keep kinda close to the original size. 15x7 wheel.

simple math here works too.

Stock tires are 205/55/R15.

that means 205mm wide treads.

15% of that size is sidewall height, so 112mm. double that to 224mm, add 15", converting mm into inches that is 8.89inches. so total 23.89 inches diameter.
