Perhaps you can go with a 275/35-17 . . .This is interesting.
I did not know that by just changing the tread width,
you are also changing the sidewall height even when the tire numbers ?
Specification Sidewall Radius Diameter Circumference Revs/Mile
245/40-17 . . . 3.9in . 12.4in . 24.7in . . . 77.6in . . . 816
275/35-17 . . . 3.8in . 12.3in . 24.6in . . . 77.2in . . . 821
