The 2017 Dodge Challenger SRT Hellcat is built on the LC platform with a 5x115mm bolt pattern and 71.5mm hub bore — a bolt pattern specific to Dodge/Chrysler muscle platforms and not interchangeable with Ford (5x114.3mm) or Chevrolet (5x120mm) fitments. This page covers 20x9.5 / 20x10.5 wheels with 275/40R20 / 305/35R20 tires in the +35 to +45mm offset range. The standard-body Hellcat (2015-2017, before the Widebody option arrived) has a front fender opening that accommodates up to approximately 275mm section width comfortably at stock ride height without fender modification. The 6-piston Brembo front caliper on Hellcat models is the primary inner barrel clearance constraint: a minimum of 20mm from the wheel mounting face to the inner lip edge at the caliper pocket is required. The factory 20-inch wheel on standard Hellcats ships with adequate clearance, but aftermarket 20x10.5 and narrower wheels must be verified individually since inner barrel profiles vary by manufacturer. The +35 to +45mm offset window on this page applies to standard-body cars only. The LC platform has a notably wide front track relative to its wheelbase, which means aggressive negative camber setups will eat the outside shoulder of front tires faster on street-driven cars. For the 275/40R20 / 305/35R20 front tire on a 20x9.5 / 20x10.5 wheel, running at manufacturer-specified inflation pressure is critical — the large supercharged engine's weight biases heavily toward the front axle, and underinflation compounds tire shoulder wear. Rear fitment on the Challenger is straightforward compared to the front: the live rear axle accepts wide tire packages without the caliper constraint, but confirm wheel well clearance at full compression since the Hellcat's performance spring rates still allow significant travel under road impact loads.
