Ironman tires

Anyone here ever run the ironman tires I found a good deal on some of the GR906 tires in 225 70 15 I had wanted to go with the cooper cobra tires but found these ironmans they have a rating of 440AA and T (118) speed rating vs the coopers 440ab! And they are about 60 bucks cheaper than the cobras looks like a winner to me. Just wanted to see if you guys have had any luck out of them?
