I see talk about 20" tires. the ram I am looking at comes with LT285/60R20E OWL tires. are these as good for towing as 18" both are E rated, but I do see a shorter sidewall
20s are as good or better for towing than the smaller rims due to less sidewall flex (theoretically). But having 17s and now 20s same truck, same camper, very similar load ratings. Both 34" tires, I can say it doesn't matter. Get the dubs if you like them!
