19 inch 664m wheel tire combo
Anyone get the performance run flat set up for the standard m550 wheel? Front: 19x8.0, 245/40 R19 Rear: 19x9.0, 275/35 R19
I'm wondering if I can go 275/40 rear without issues. I'm just too afraid to get the 20's with NY roads so at least want staggered rear with wider tire. Thanks |

Assuming you're talking about the Pirelli Cinturato P7 Run Flat tires, the 275/40/19 you're asking about is 1.2" taller than the front (245/40/19) so while you probably won't have any issues, the look itself would be odd and would not recommend it.
The standard set up: 245/40/19 and 275/35/19 is a staggered set up with wider rear tires. That's what you're looking for, right? Your first set of numbers on a tire indicate the width of a tire while the second set of numbers indicate sidewall. A 275/35/19 and a 275/40/19 are very similar in width (both are 275)- 0.3" difference in this case. Hope that makes sense. EDIT: They don't even make a 275/40/19 in the regular Cinturato P7 Run Flat, it only comes in the All-Season variant. So that definitely rules it out because you don't want 275/40/19 (27.8" tall) All-Season tires on the rear and then the 245/40/19 (26.7" tall) performance version on the front.
