Replacement tires

Changed to Goodyear Endurance last fall. TT is a hair over 9K lbs. We have had the TT for many years. Having ST tires that limited to 65mph max was annoying. I don't really have much opportunity here in the NW to go much faster, but I do like pulling right at 65 (or a tad more) and did not like being constantly at the design max. Eastern Wa is mostly high desert with summer temps typically in the 90's. I've destroyed 3 Marathons on other TTs I've owned. Last year I ordered a F-350 CC LB diesel with the trailer tow package that reads trailer tps and has the rear camera. The tires had to come off to put in tp sensors. When I started the tire changeover I found that the stock wheels and the OE tire sizes were only barely sufficient (imho) to handle the loads put upon them. No steel wheels were rated high enough. I ended up with alloy wheels and load range E Endurances. Now truck and TT tires take the same max PSI, 80. We are nearly 19K when taking the ATVs and stuff in the truck. It feels good to be hauling with new iron and good rubber. Good luck all.
