Radius of Stock Tires Anyone know the radius of the stock z tires? Just put in new gears and need to know the radius of the stock tires to program the computer correctly... 245/50/16 are my stock tire dimensions... Thanks.
Re: Radius of Stock Tires Here's a quick lesson in math and tire sizing. The first number 245 in a tire size is the size in millimeters of the width of the tire. the next number is the height of the sidewall also referred to as "aspect ratio" to get the height of the sidewall you multiply the tire width by the aspect ratio so for a 245/50 tire it would be 245mm x .50 = 122.5 mm so to get the overall height of the tire you multiply the sidewall size by 2 and add the size of the rim so
(122.5 x 2) + 16
to convert mm to inches divide by 25.4 so
(4.82" x 2) + 16 or 25.64 is the total tire height. I dont know what programmer you're using but most want the total tire diameter not the radius i think. But if you want the radius just half the diameter <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
