Yup. It's in the build sheet. Mine came with staggered size Goodyear's according to the build sheet, though it's listed under the "optional equipment" listing.What? So, you're saying your car came with two different oddball sizes from the factory? Check the tire placard on the door frame.
Did you just say you bet two new rear tires the factory NEVER installed different sizes front and rear? I'll give you an example right now: 1970 Plymouth AAR Cuda and 1970 Dodge Challenger T/A; E60/15 Goodyear Polyglas GT on the front; and G60/15 Goodyear Polyglas GT on rears.Ok, those are not staggered though. Staggered is 245/45/20 and 275/40x20, the same diameter. The rears are an inch taller than the fronts which a factory would never do. PLEASE, look it up on Tire Rack and let us know, or give us the car info and we'll look it up for you. I'll be you two rear tires the factory didn't do that! 😁
