im glad i went with 265's in front. any wider would rub. with saleen replicas you really shouldnt go any wider than 265's in front because they already sit out far enough in front.... and i've had minor rubbing problems on extremely steep driveways.
now for the back...i would definitely consider going wider than 295's. its just a matter of a very small selection of 305 sized tires that are not DRs.
