Those are Bias ply. It says right on their website:
"Pro Trac tires are perfect for your Pro Street, street machine or hot rod, thanks to a super wide profile that offers the race ready look without the safety concerns of driving on the street with actual racing slicks. Protrac tires are DOT approved, bias ply tires and they're perfect for a car that is mini-tubbed. The tread pattern has been thoroughly tested to ensure safety in dry and wet conditions. Street machines are making a big comeback, so put your ride back on the road with a new set of BIG Pro-Trac tires. Check out the
front runners, too!"
They're made for a look. What's the treadwear? Temperature rating? Speed Rating? Sounds like they're for show poodles.
