The 2012 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 LC platform Challenger uses a 5x115mm bolt pattern with 71.5mm hub bore on all production years. The Brembo 6-piston front caliper package on Hellcat trim levels requires careful inner barrel clearance verification on any wheel under 20x10 width. Wider wheels at narrower widths can actually create clearance issues if the inner barrel profile is shallow — barrel depth matters as much as offset value for caliper fitment on high-performance brake systems. 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.
