"know how poor the handling was"; with the stock wheels? I think that it handles quite well, and a hell of a lot better than 90+% of the new cars out there.

It handles well, but taking it past where most people drive shows just how much of a boat it can be. I'm a kid, so I drive dumb and fast, but I've done road racing schools, so I know how to take corners, and the 300 really doesn't do them that great, especially w/ stock tires... fat sidewalls and mediocre grip. I can't wait to get some lower sidewall, wider, performance tires on.

Put some 20's and some higher performance tires on your car and you will agree with me. For a big car the stock 18's handle OK for what they are designed for - high mileage, nice ride. With the 20's on the ride quality is very close to stock and handling is much improved in my opinion.

Look great, but I Have some questions.:D

Did you have to use spacers do the difference in offset requirements between the two vehicles.

Where did you get them?

How much were they?

steverwrx ,

Throw us a bone man!

LOL

Running the Goodyear Eagle RSA 245/45/20. No spacers or grinding required. The 255/45/20 Goodyear Eagle F1 are slightly too wide for front fitment. The wheels should be available from your local dealer soon in the $450-$500 range.

Steve,

What do you think about running the 255 Goodyear's in the rear with the 245's up front? Please advise, as I have a blimp tattooed on my rear end...I think all old Goodyear retirees do. ;)

The Goodyear F1 255/45/20 does fit fine on the rear. I wanted to keep the same tire type all the way around. If Goodyear releases a 255/45 or 275/40 in the Eagle RSA, I might change the rear tire size next change.

... you should probably do something about that tatoo ;)

Thanks for the info...and you're right about the tattoo. Fortunately, it washes-off when the need arises. ;)

You sure spacers aren't required?

But I am still unsrure how this setup works without having a rubbing issue on the steering knuckle.

THIS POST states the ideal offset for a 20" wheel on the 300C is 21-24 mm.

Furthermore, according to THIS POST, the offset on the SRT wheels is 25.5 mm.

Finally, I asked about the need for spacers in putting SRT wheels on a 300C in THIS THREAD , and THIS THREAD on the Brampton Factory messageboard.

It was indicated in both threads, that a minimal spacer of 5 mm was needed for this to work properly.

steverwrx, are you SURE that you aren't getting some bump and grind in there and that you wouldn't be better off with a spacer? That is a signifigant change from a 24mm offset to a 25.5 mm one.

You took alot of time patching all those links together. The supposedly "ideal 21-24mm offset" is on a 8.5" wide wheel. The SRT wheel is 9" wide. Anyways 1.5 mm or .059" is really not much :)

On my car the steering knuckle is about 6-7 mm away from the tire. I just slipped a 9 mm dia pen through the space with little interference. The tires have been on the car for about 3 weeks and 500 miles or so and there no evidence of tire to knuckle contact. Maybe my car is a freak of nature ;) I Don't care. I love it! My wife loves it too. She commented today on how much better it handles. Actually her car..... but that's another story.

Steve,

Thanks for all of your prior posts regarding this particular subject, as this information has been extremely helpful. :cool:

Update:

Maybe some '300 series' models might just be built a little different from car to car...have slightly different tolerances. My dealer and I also test-fitted an OEM 'SRT-8' wheel (with a mounted P245/45ZR20 Goodyear 'Eagle') onto the front of my car, and although it came close, fortunately, there was no tire and/or wheel rubbing problem(s) noted nor were there any other related issues to be concerned of. :)

Thanks for the reply! Just thought I would point out that Ted over at www.wyckoffchryslerparts.com just test fit these on a 300C and said he is definately getting rubbing. He said a 5-10mm spacer WILL be required.

HERE IS THE LINK.

Seems like we have conflicting information on this.

New photos of "Clyde". My wife named the car. :D I am very happy with the look and performance of the new tires and wheels. All of you who changed out the stock tires already know how poor the handling was. The new Goodyears handle awesome! Seems more stable at higher speeds too :)

I plan to install the SRT-8 wheel package as you did , would the speedometer change if you do this and how to fix this? Thanks

The 245/45/20 and 225/60/18 are almost identical in their outside diameter. So no worries regarding speedometer calibration.
