Last night time, Dodge took the wraps off the most outrageous Challenger however: The SRT Demon 170, generating 1,025 horsepower on E85 and able of -60 in 1.66 seconds and an 8.91-2nd quarter-mile (on a prepped drag strip, with a genuine very hot-shoe at the wheel). Further than just the horsepower, a great deal of that acceleration electric power is down to the tires, Mickey Thompson ET Road R drag radials, which are hardly avenue-legal and created for drag-strip overall performance. The Demon 170 accentuates its skinny-front-excess fat-rear staggered tire setup by ditching the Widebody flares up front, but a closer appear reveals that people “skinny” front tires aren’t so skinny. In reality, they are incrementally larger than the stock tires you get on a base-product V6-driven Challenger SXT.
The Demon 170’s entrance tires measure 245/55R-18, mounted to a lightweight 18-by-8-inch wheel which is both totally aluminum or, optionally, aluminum and carbon fiber. The rear tires, of class, are monstrous, 315/50R-17s on 17-by-11-inch wheels. Dodge experienced to modify the Challenger’s rear suspension to in shape individuals meaty virtually-slicks, but let us focus on that entrance tire for a sec, because a no-possibility Challenger SXT rolls off the dealership large amount donning 235/55R-18 all-seasons.
Don’t forget how tire dimensions perform: The very first quantity is the tread width, in millimeters the 2nd range is the aspect ratio — in other words, the sidewall peak calculated as a share of the tread width. The final quantity is the diameter of the wheel. So, the Demon 170’s entrance tires are 245 mm huge at the tread and the sidewall is 55 % of 245 mm, whilst the Challenger SXT’s tires (all 4 of them) are 235 mm broad with a sidewall that’s 55 % of 235 mm.
Here’s an less difficult way to fully grasp it. According to TireSize.com, the Demon 170’s front 245s have an total diameter of 28.6 inches and a width of 9.6 inches from the exact site, the Challenger SXT’s 235s evaluate 28.2 inches in diameter and 9.3 inches extensive when mounted.

In other words and phrases, 245s are not genuinely that skinny of a tire, and they’re not even the smallest tire provided on the Challenger platform to usual day to day prospective buyers. This gets to be suitable when you recall that the 2018 Dodge Challenger SRT Demon, supplied actually skinny entrance tires for drag racing as portion of the $1-selection Demon Crate. Those entrance-runner tires were being too little to be avenue-authorized (for this reason why Dodge would only promote them to you in a box independent from the auto), and apparently, the ethanol-run Demon 170 does not even require those monitor-only skinny tires to obliterate the aged Demon’s 9.65-2nd quarter-mile time.
