275 40 17 on 65/6 mustang...I'm willing to listen...

I want one measurement please.....

There are 2 guys on this forum who say they run them on 17x8 rim.

Can you please take a 2x4 and hold them to each side of tire mounted on rim and measure space between the 2x4 so I can have an extremely accurate measurement of the section width on your tire please.

I appreciate your help.

I have been leveraging resources and here is what I have found out:

275 40 17 KDW on a 17x9.5 rim: exact measurement is 11.5 inch between the 2x4s Per Tirerack - section width is 10.9

275 40 17 goodyear F-1 on a 17x8 rim: exact measurement is 10.25 inch between the 2x4s Per tirerack - section width is 10.8

My 255 40 17 KDW on 17x8: exact measurement is 10 inch between the 2x4s. Tirerack - section width of 10.2


Sooo anyway the excercise....and why I am interested....Just picked up 275 40 17 BFG DR for DIRT CHEAP...and was thinking about running a 17x9.5 for them with custom backspacing...but it looks like I can gain over a full inch by staying with the 8 inch rim and living with the degraded contact patch. Since it is a drag radial I should get a little better performance out of it that my 255s. I suppose we will see
