Tow rig is Ford Excursion 7.3. Trailer is 35' long about 9,000 lbs. I'm interested in the best tire for towing, for example a stiff sidewall to limit flex. After doing a little research it see...
If you don't have it, get Airlift and put on the rear. We run Michelin LT/MS. Best all around and only inflate to 60 lb. I don't understand why you think you need 70 lb but maybe you like the Kidney jarring effect. We haul a 10 K trailer, GCVW 19800. MS2s have greater grip, greater water cahnelling and better traction on snow-slush.
