2017 Exp EL. Towing 6000 lbs. Brand new Falcon Wildpeak A/T 4W. When towing I run them at 50 psi. The rig tires around 55, have yet to get the exact psi but I feel Im close. Over 60 mpg trailer starts getting a sway going. The trailer could be loaded or empty issue is the same. Ive been looking into EBS or Equal-i-zer Weight Distribution.
I feel it's the truck anyone else experience this?
Hi All. First posting here, now on 3rd Expedition since 2011... Just retired, 53 years in Tires, Brakes, Alignment business. Been towing a Vintage Racecar since 1998 in different 20 or 24' enclosed trailers... All Terrain tires not best choice for towing...tread is usually deeper than Highway tread, lots of grooves and channels= less rubber ON the road allows "Tread Squirm" at speed, and the trailer amplifies that. 55 psi is too high- sidewalls get stiffer which is good, but the tread contact patch gets smaller, which is not good. 55 psi in the front is crazy high- makes the steering too sensitive, you can't relax and get the "white knuckle" symptoms. Unless the new tires are 10-Ply, I'd suggest 36 psi front and 40-44 psi rear. Try that and see... Last but not least! Get a Weight Distributing Hitch WITH Anti Sway System- it works! I use a HUSKY unit I've had for years, but there are many other choices out there. Good Luck! Let us know how you make out... Ernie
