Olblu, I ran an other model of Bridgestone for 3 years ( Dueler AT's) rated for a 6,5 rim with no problem except it just didnt 'look' right...
The sidewall buldges and it looks goofy.
The R273 is rated for a
5 inch rim, right on the money... It is very narrow and I could now steer with a pinky (not that I actually do...

)
