What are the chances that you'll be around town when you get a flat with the trailer... You will most likely be out of town and stuck if you can't get it fixed...
Yes, good insurance, but like Tim stated most of the places we go to with it dont have a discount tire around and I will have to deal with a mom and pop shop repair the tire anyways.. Hell I really dont want to spend $500 on new tires when the trailer is brand new to start with... Why do they install cheap chinese tires on these things?? Install good tires from the get go!
