Stop in for a cup of coffee

Hey quick tire question again. Looking at Discount Tire for those trailer tires I want. Would the certificates be worth it on a travel trailer that will probably only be pulled 3k miles per year?

Road hazard? I would think it's good insurance...

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...
