OE Michelin SC2 on 11.5 rims

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others.

I am switching to apex 11.5’ rims with et56 backspacing in preparation to Start using hoosier r7’s. Since they are only available in 315’s on a 19’‘ rim, i have to go to 11.5’ rims square, which means now i have to go to R spec studs and 31mm spacers.

my question.....i just bought a set of 305/30/19 sc2’s.......will they fit on these 11.5’’ rims or am i over stretching them. The specs on tirersck show from 10.5-11.5 is rims width suggestion, but want to make sure. If not, then i’ll just stick with my 19x11’s til next year.

Here's a screen capture from Michelin's spec sheet for PSC2's. The red arrows are the Ford GT350R spec tires.

Both tires have the same rim spec, so 11.5's will be fine.
