I have the staggered 19" fat setup. Does anyone know the total diameter of these wheels?

245/40/19 (front)

275/35/19 (rear)

Thanks in advance.

245 * 0.4 / 25.4 * 2 + 19 = 26.7
275 * 0.35 / 25.4 * 2 + 19 = 26.6

Rom--- I didn't know that formula for outside diameter based on tire size... thanks

KevinGS

I think I got it, Rom...the formula that is. But why did you divide by 25.4?

no problem guys, anything to help, it's all about information

1 inch = 25.4mm. 245 or 275, that's mm, not inch. so after you do the math to get the sidewall, you need to divide it by 25.4 to get the value in inches

ohhhhhhhhhhhhhhhh, makes sense now, Rom. Gotta get the units right. Gotcha!
