D-50,
You may want to try asking Jason Moulton , from MT , over on Yellowbullet . He was helpful to me , though i have gone back to Hoosier radials . I have tried the lightweight Hoosier 9x30 , 29.9 dia . Was very happy but did not have enough gear . I am only a small radial guy , Hoosier 275 , with not enough power .
