    As the title states, I've been reading so many conflicting things that I'm at a loss. On one side I hear people saying you can easily put 275/40/r20 on the stock 9 inch wheel and it will give better tractions. On the other side I hear people saying that 275 is to wide for a 9 inch wheel. While they will fit, you will get some tread overhang and essentially get the same exact contact patch as the stock 245.

    I'm about to take the plunge and get factory reproduction hellcat reps in 9.5's. However if this isn't necessary and I can just throw tires on my factory rims (which I do like) I'd prefer that

    Whats the real answer here?

    Rocco, we need a real question here.

    If I guess at what you are asking:
    Yes 275 will fit your stock rims.
    Yes 275 will have a bigger contact patch.
    Yes 275 will stick out further than 245s.

    Lol.

    I get that they will “fit”. But if I’m going to get literally no added benifit besides slight cosmetic on a 9 inch wheel then it’s not worth it. But I do see other people saying their traction has improved. Placebo?

    For me, the switch from 245's to 275's on a 9" wide wheel was an awesome upgrade. Traction is better in all conditions.

    Really? What tires did you end up going with?

    Original tire was the GY F1's and I really disliked them. They were hard, and had terrible traction. I could spin them nearly anywhere and often did even at speeds below 60 when I would nail the throttle. I got Cooper Zeon RS3-G1's in the 275 size on all 4 corners and now, i have no traction issues. Wet traction is amazing over the F1's, Cornering feels better, the rides better. I'm very impressed with these tires.

    Only downside that I see is a lost of 1 mpg overall due to the later size. I drive it 70 miles per day to/from work and noticed the 1 mpg difference. But the trade off in better ride, alot less noise and better traction was well worth the 1mpg loss. I highly recommend this tire.

    I was planning on moving to 275's too, I never thought about a possible loss in mpgs!

    That’s good to know, thanks for the info. I will look into these tires when mine are due to be replaced.

    Out of curiousity, do you attribute the better traction and handing due to just being an all around better tire and not the size difference?

    More rolling mass and wider contact patch.

    Well, I had the goodyear F1's on a previously owned 2012 SRT and replaced them with OE size 245's Cooper RS3-A's and felt they were superior over the Good years. Now I have a 2013 SRT and once again, replaced the crappy Goodyear F1's with the Cooper RS3-G1's and believe the 275's I have now provide even better traction. So yes, they're a better tire in my opinion and the wider tire offers better traction in my experience.

    Is your rim a 9 inch or 9.5?

    Sorry for all the questions, just trying to get a clearer cut answer from all the conflicting articles and post I read. I will probably be ordering these tires though thanks to you.

    Stock SRT 9" wide wheels. They have good sales too if there's not one now. Usually No less than $100 off when you by a set and sometimes, it's buy 3 get one free.

    I am not sure I want to lose 4 wheel tire rotations... I am unfamiliar with how the tires on my Scat Pack wear

    Oh, I completely understand. As you know, 9-9.5" width paired with 275/40R20 tends to be a popular, wider fitment.
