I am not sure what the tire issue is here. The trailer should still have a “E” (not “c”) tire which is essentially a truck tire. One should not skimp on tires. The very best tires are a must. The last thing you want is to have a blow out. The blow out will damage your wheel well at the least and at the worst, it may cause you to lose control of your vehicle. A tire cleaner that DOES NOT have petroleum distillates is a must. If you are parked for an extended time, then really good tire covers are necessary. I currently have a 5th wheel that is a dream to pull. I had a bumper pull that was easier to park. Both were great. I have had unlimited use of a 38’class A. It is really a nice home, but you are seriously limited as to where you can go with it. I boon dock most of the time, so this is an issue for me.
