no, go with the 1.75" spacers (commonly referred to as 2") and you can fit 31s. but it is going to depend on the make of the tire, some run taller, some wider, so you might have to trim a little bit inside the wheel wells and the part of the bumper in front of the wheel wells. again, minor trimming, nothing serious, but with a 2" budget boost you can fit 31s.
