Wheels and tires make a huge difference in towing. I’ve never owned a six cylinder in a full size truck but be very cautious of getting all terrain tires. Personally, I’d avoid them, go with Michelin High mileage highway tires like Defenders. Research them on Discount Tire website, comparing weight of tires and make sure to stay with original equipment sizes cause you’ll most likely notice an improvement and you can sell your wheels and tires later after.
