The drag radials on my 66 Coronet were getting really bald so I switched from Drag Radial TA's to street BF Goodrich Radial TA's. Wow! these street radials are really slippery compared to the drags. I didn't realize how sticky the drags were until I put these on. I only did it so I would have some tread depth for street use. I kind of regret it now.

 

Street TA radials probably have a tread wear of 300. The drag radials tread wear 0

 

Well... You dont need to wonder anymore.....lol Now you know...

 

BF Goodrich Radial T/A are great looking tires. They are also All-season tires so you can drive your classic 1966 Dodge in the snow. I know we all want to do that. This is one of the reasons I decided to put 17's on my Challenger.
There is a lack of good quality tire in the 15" sizes short of the drag radials.
If you get a chance to try out the BFG g-force COMP 2, the Rival or the Michelin Super Sport you wont go back to 15's
Watch for an upcoming article in Hot Rod magazine where they test some of the best street tires available on a '70 Plymouth.

 

BFG Radial TA 's are easy to white smoke but they have a nice profile
