Are your MT drag radials 20"? If so what PSI are you running on the street? I have the 20" ET ' S also on oem 10 spokes and I feel that they don't feel very stable say 80mph and higher. They like walk side to side and just doesn't feel solid and safe at all. Am I not running The right PSI?

They are the 20" drag radials mounted on stock 20" wheels. I run around 32 psi in them on the street. I've had my car up to 165mph and they felt stable.

Ok originally I think it had like 32-34 psi and about an 1/1.5" were not contacting the road on the inner and outer edges. So I dropped it to 26psi and that's when it didn't feel right. I think I'm gonna try 32 and check it out again.
