my bro recently baught a 1st gen JDM B16A and he would like to know the diffrence between his tire diameter and the donor car's for speedo accuracy

so it could have been taken out of 3 things:

JDM EF8 CRX SiR
JDM EF9 Civic SiR
JDM DA9 Integra X-Si

anyone know the stock tire sizes for theese cars?

 

okay okay so it was 3 questions.....so tire sizes anyone?

 

use this when you do find the stock tire sizes ... and compare it to your stock tire size... and it will tell you everythign you need to know about changing tire sizes and rim sizes... after you find the stock of course

Assuming that the EF8/EF9 had the same 185/60/14 tire size you can calculate the difference at this site.....
