Another New Toy Challenger Hellcat

[njsteve]

And another thing: Delete those factory tires! The assembly line Pirellis are terrible to the point of being dangerous and have been the cause of most Hellcat wrecks. They are like petrified hockey pucks. Go get a set of the Michelin Pilot Sport 4S tires. They are a night and day difference. You can stomp on the gas and the car will track dead straight ahead versus the Pirellis that will stick on one side and then the other, unpredictably and send you into the nearest fixed concrete obstacle. We installed a set on ours and the 0 to 60 went from 5.5 seconds spinning to 3.6 seconds sticking. It's a frightening car when it gets going. I don't think I have hit the go pedal fully for more than three seconds straight at a time, as the car accelerates forward so violently. It's like the scariest rollercoaster I've ever been on.

This is the perfect time to buy them too, all the Christmas sales at the various tire warehouses are on now.

Added note: the Pirellis we took off the Redeye went on my son's 2011 R/T 6-speed and they are amazing on that car. I guess it comes down to the hellcat's 800 horsepower being way too much for the tire compound they have on the car. They work just fine on a 376hp R/T hemi.

Should I stay with the same size tires?

You can go up a size from the 275/40-20's to a 285/35-20 on the rears but you only pick up a 1/2" more width and lose 3/4" in height. To go any larger like a 305/35-20 you need much wider rims than the 9.5" wide stock narrow-body ones.
