275s on 8.5" rim...

[-The Stig-]

The wheels I'm looking at buying are 17x8.5, even in 18's they're 8.5.

And I would like to run a 275/40's on all four corners.


Question is... will the tire safely fit on the rim? According to Tirerack.com they say the 275/40 requires a 9-11" rim. Will that -.5" make a huge difference? Or am I stuck with 265s or a 255?



I've seen online people mention that you can't fit/shouldn't fit larger than 255 but other folks have said 275s fit fine on a 8.5" wide rim.

My Google machine hasn't been very accurate in getting me the answers I need.

Appreciate any/all input!
