I have run the 18211 for many many years and have the car gearing set up for that 94" circumference... I guess all things considered I will go with the 18212. I just thought maybe someone has found another manufacture with a radial slick that has all the same measurements as the Hoosier 18211..

By the math, the 92.5" tire would be turning 7110 RPM where the 94" tire would be turning 7000. Not a tremendous difference.
With that said, there are a lot of people who are happy with the 18212.
