I will never run an Interco product again, much less so on a street driven vehicle.
I had them on our 03 Discovery. They were about 18 months old, when they decided to come apart.
My wife and son (10 months old at the time) were on there way to her parents house in Logandale, NV. She was about 1 mile north of Mesquite and a 5" diameter chunk blew out from the passenger rear sidewall. All of this happened while she was travelling 75 MPH. When the tire blew it caused the vehicle to immediately turn to the left, she tried to slow down but this had an adverse effect (the highway patrol said she should have accelerated) thus causing the vehicle to roll one complete barrel roll followed by a complete end over end roll.
Enough of that rant. In the end my family was safe. I fully attribute this to the Design and build quality of our Land Rover.
So in my mind it is not worth the $200-300 you will save from buying these less expensive tires. Especially when you have to replace a $45000 vehicle.
The insurance company had a lab inspect the tire and no one can explain why it happened.
