[cowboyupdan]

who knows what the equivalant to a 35" in metric is?

325-75 or so   i dont think they make that size

Depending on width and rim, around a 345

315-75-16 is 34.5" tall.  Per tire rack dunlop radial mud rover.  There is a couple brands at this size

see but that comes up that way because of the 16 inch rim.

I was trying all the calculation's into the thing and it all would change on the width, and the size of the rim.  16" rim always made the tire large...?

345/75/15 = 35.37

345/75/16 = 36.37

That's because in the metric system all the numbers are relative to each other...  You change one value and they all tweak.

As Jeff pointed out, its a total of the numbers.

Section Width/Aspect ratio/rim size

So a

345/75/16 is the following.

345 = section width (not the diameter) as measured from the widest point of the sidewall in mm.

75 = Aspect ratio. This means that the sidewall height is 75% of the section width. In this case 345*.75 = 258.75. Therefore the sidewall height is 258.75mm.

1 inch = 2.54cm (or 25.4mm)

Therefore a 16" rim = 406.4mm

So to get your total diameter:

Sidwall Height (X 2) + Rim

(258.75mm x 2)  + 406.4mm = 923.9mm

so to convert mm to inches you divide by 25.4

923.9mm / 25.4 = 36.37inches

So a 345/75/16 is 36.37" tall

345 / 75 / 16

Tire Width / Tire Aspect Ratio / Rim Size

Tire Width = W
Tire Aspect Ratio = AR
Rim Size = Rim
Tire Diameter in Inches = TDIN

So the formula is....

(((W * AR) * 2) + (Rim * 25.4)) / 24.5 = TDIN

Just get a 35"......easier....lol.

Vipers come with a 345 on the rear, but they are less than 30".

345/35/20 = 29.5" total diameter
