I'll echo Shari. You stand to lose a lot more that the cost of the tires if you blow one. If I were in your shoes I would shop the cost of a new off brand tire that is rated properly. That means it might be a tire named "Jack"...never heard of it but its rated ok and I can save $$. Then I don't feel too bad about that new cheap tire sitting since you are only using it one time.
