Blow Out

I took giddyup last week and had her oil, filer change and grease and I had the tires air up to 90PSI. While they were on the right side airing up the tires the one on the left side dual blow out. So I will take  her to have new tire installed tomorrow. I bet it will cost me about 350.00 dollars, them tires are not about three years old, However Goodyear has had a lot of trouble with those RV tires. I wish I had went ahead and put Michelin's back on it. I have never had a blow out on them Michelin's. And that the way it is with Paw today.
