LT tires on the truck. New on the back decent on the front. Trailer tires are three ST 225/75 and one 7 X 15 - all have some cracking. All will be replaced in the coming year but are suitable for local trips.
The truck is 4X4, 5.4, factory tow, which includes big trans cooler, and i believe a larger radiator.
When towing the 4500 lb trailer the trans temp stayed around 160F I think. I don't recall the temp but it was no different when not towing so i figured i had a lot margin to go to the bigger trailer. Trans temp is currently inop but I'll fix it before serious travel happens.
