I'm going from 14 to 15 inch rims on my Subaru and I need to know the correct tire size please.

google ''miata tire size calculator'' and you should find a place to put in your size and then calculate a 15 inch size.

 

but if i remember correctly, 195/60/15 .

TireRack will also tell you OEM tire sizes. You just have to plug in what year and model the wheels came from.

My stock tires are 185/70-14. The calculator won't work on my phone.

He has to convert to keep an accurate speedo. Stock size is irrelevant.

195/60r15
