Hope this makes sence.

you have to calculate to get to the closest to stock total diameter.
ive noted several examples to cooltoy, check out the tread.

basically take the width (in mm) multiply by sidewall in percentage.
then take your wheel diameter multiply 25.4 to convert the diameter in mm.

then diameter + sidewall x2 = your total diameter. btw, use excel.
