here have all the TA Radials Gone?

WHY ARE THERE NO 50 SERIES 15 inch TIRES ANYMORE?! The only one's that are out there are the Cooper 295s. Now, I love the way they look on my caprice, but I want a set of 245 or 255s on the cuda. I like the "retro" look of 15s, but I also like the low profile look and freaking 50 series were the best looking compromisePERIOD It pisses me off.
