    305 rear tires on stock wheels?

    Time to replace the rear tires. I thinking of going with Continental ExtremeContact DW in a 305/30ZR19.

    Has anyone ran these tires with this size on stock wheels? If not, has anyone ran any brand of tire in a 305 size in the rear? If so, What.

    Thanks.

    I had 305s on the rear. No issues. Bridgestone Re11s.

    305s look nice but remember the open area in your rear wheel well will be much bigger with 30 vs 35s.

    Not sure if anyone makes a 305.35.19. A 295.35.19 would probably look better than a 305.30 unless you plan to lower the car.

    Where is the cross-over to excessive rolling resistance above traction gained?

    I think Cadillac already did the engineering for us. I'm using the supposedly stickier RE-11, but in stock size. I'd go a touch bigger if they made these in 295s.

    Do the RE-11's hook better than the PS2's?
