If there is ever a time to NOT go cheap, it's buying tires for your camper.  There are many stories of blowouts, destroyed wheel wells, peeling back the side of your camper and more.

Our last three campers have all had Load Star tires that have worked well.  We are replacing ours because of dry rot cracking since they are 10 years old.  You can buy  ST205/75D14 without rims from Etrailer or Home Depot of all places for $77 each.  Much cheaper than everywhere else and they look great.

Do research, ask questions. Don't go cheap
