Good Morning guys! I needs your help soonest. I have a 06 screw fx4. With oem 275/55 R20 Perelli ATR's. Our transportation guy here at work has a deal for me. I need you all okay please. He can sell me a set of 4 new bf 285/65/20 tires for 400.00 dollars. Will they work? What will it do to my speed indicator? Thanks for sharing your wisdom.
Marcel

 

275/55/20 = 31.9x10.8/20

285/65/20 = 34.6x11.2/20

They'll fit, and that's a $teal!!

 

I guess its a perk being in management. Will I have to adjust the speedometer? Again thanks.
