I've been told by knowledgeable sources that running LT215R85 by 16 inch radials on the STOCK rims withOUT tubes is dangerous,
Running modern tubeless radial tires WITH tube is ILLEGAL and potentially very dangerous. The tube and tire inner layer chafe against each other when the vehicle is driven, causing exessive heat, leading to tire failure. I've seen them fail within 100 miles of driving. Only run tubes in tube type tires.
