most would recommend radial front and rear . I guess some of that will depend on your mph and the tyre speed rating .
I have seen those MT SR fronts go out of round/ delaminate . Not a big fan of them . I use street radial tyres front though i think a little shorter than yours ,28"? Mine are 185/80R15 also 185R15 (26.7") waiting on the shelf . I am only going 131ish mph max .
