pro is only available 275/60-15
as for it being larger .. 275/60 is 275/60 28" tall
yeah its larger than the tire you have next to it in the pic whatever that size is but looks like a 275/50 ... 60's at 28" are bigger than 50's at 26" so not sure what your post is meant to say
so far the pro hooks better than the std et radial . 1.33 60s so far and they haven spun once on a launch.. waiting for the cooler weather to step up the launch boost and try for lower 60s
i have mine on 10" wide rims with a frame notch so i can have them tucked under the fender
i wont be going back to et street radials
I always heard that the pro was equal to a 28x10.5 slick which I can't fit without it rubbing on the frame or digging into the sidewall. After looking at m/t site it's not much different at all. Sorry for the mis-information.
