About the 275/40R20 size
Hellcat size, Y rated XL (106Y). Summer UHP from Pirelli (OE P Zero), Michelin and Continental; UHP all-seasons exist for year-round drivers.
The numbers mean: 275 mm section width, sidewall height 40 % of that width, and a 20-inch rim. Overall diameter works out to about 28.7 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

What is the best 275/40R20 tire?
For most drivers our mid-range pick, the Firestone Firehawk Indy 500, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Michelin Pilot Sport 4S is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 275/40R20 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
