I have read too many threads to count, here is what I am looking at. I want either a 255 or 285, both fit and both will fit in spare tire location, I need to know a little about towing characteristics as I regularly tow my 20 ft boat and occasionally a small camper. Looking at Cooper ST Maxx and KO2's. Any thoughts or experiences, I have ran the Cooper's on a 4runner and really liked those, just wondering about towing stability. Thanks
