HI, I have a question, I would like to put cooper discovery's 255/85r/16's on my stock 250psd supercab long bed 4x4,I presently have the 265/ 75r/16's firestones now. Are there any fit problems with these new tires? any recalibration needed? are these decent tires or does anyone have any better suggestions. I realize that these are D rated tires,I would like this size in an E rating but I dont think they make them. thank you in advance bruce

 

 

You should have no problem switching to the narrower tire. The only thing is the tire might be a little taller. But go right ahead and do it, normally people go with a wider tire, in my opinion, i think u shouldgo bigger!!
