How Much Wider?
The difference between 775/75/15 and 205/75/15? Thanks, Bill.

Bill,
Go to www.tirerack.com and they have a user friendly tire size comparison chart. You put in the tire size they supply the info. -

7.75-15's were typically 7.6" section width (although redlines and goldlines were a little wider), and 205/75-15's are typically 8.0".Comment

Re: How Much Wider?
John, When you refer to section width, is that the amount of rubber that meets the road? Bill.Comment

Re: How Much Wider?
John,
See chart below from the Tire Rack website:
Calculating Tire Dimensions
Width x Aspect Ratio = Section Height
Section Height x 2 = Combined Section Height
Combined Section Height + Wheel Diameter = Tire Diameter
Example: 185/60R14 85H or 185/60HR14
185mm x .60=111mm
111mm x 2=222mm
222mm + 355.6mm(14")= 577.6mm or 22.74"
The first number is the width of the tire in millimeters, measured from sidewall to sidewall. To convert to inches, divide by 25.4 In the example above, the width is 185mm or 7.28".
The second number is the aspect ratio. This is a ratio of sidewall height to width. In the example above, the tire is 7.28" wide, multiply that by the aspect ratio to find the height of one sidewall. In this case, 185x0.60=111mm or 7.28"x0.60=4.36".
The last number is the diameter of the wheel in inches.
To figure the outside diameter of a tire, take the sidewall height and multiply by 2,(remember that the diameter is made up of 2 sidewalls, the one above the wheel, and the one below the wheel) and add the diameter of the wheel to get your answer.Comment

Guys, all I want to know is how wide in the tire that meets the road using 205's. 6", 6&1/2" etc. Bill.Comment
