275 60 BFG`s
hi
It may seem stupid to ask but how tall 27 or 28" is a 275 60 15 goodrich? thanks |
The O.D. is 27.5 inches according to the specs I've seen.
|
The tire calculator at SmokeMUP.com..
says they are 27.99".

My BFG Charts says:
Rim width range - 7.0 - 11.00 Overall diameter - 28.0 Tread width - 8.9 Section width on measuring rim width** - 11" on 8" rim ** Section width varies approximately 0.2" for every 0.5" change in rim width |
Thanks guys....

(275 mm wide x 60% aspect ratio) x 2 = 12.99" + 15" for rim = 28"
|
My calculations:
275 X .6 = 165 millimeters is side wall height (aspect ratio is the relationship between the tread width and the side wall height) Multiply millimeters by .039 to get inches : .039 X 165 = 6.435 inches. Multiply by 2 to get both side wall heights (top and bottom of tire): 6.435 X 2 = 12.87 Add this to the 15" wheel diameter: 15 + 12.87 = 27.87 inches Paul |
I was just looking this up yesterday - take a look at the attached chart from the Tire Rack....
