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! 😁Yes they did, certain years of Challenger SRTs came with staggered tires.
