I'm looking into buying a used set of ET streets, the seller has both 26X10.5X15 and 26X11.5X15 sizes. The 11.5 wide ones are in a little better condition. Will these fit OK on a V6 15" wheel? Anyone running either of these sizes, and if so what type of wheel are you running? I'm worried about the 11.5" not fitting under the wheel wells with the V6 wheel, not so much the width of the wheel. Thanks.
