I purchased a low mileage 2013 Charger SRT8 (16k miles) just a few days ago. Great car!
Here's a pic:

One of the things that really stood out was the wheelspin however, the tires were just too easy to light up even in 2nd gear. It actually felt kinda worse than the wheelspin I had in my old front wheel drive SRT4.

I think the prior owner may have been excessive on the burnouts, because the rear tires look kinda worn. They are Pirelli's 245, which can be seen here:

I'm pretty sure the stock SRT chrome wheels are 20x9. I've read people here put 275's on them. Would that be desirable even if the front 245 tires are left alone, or would it be better to go the same all around?

I'm looking for the stickiest tires I can get that also has great wet traction. I live in central Florida, it almost never gets cold here (and when it does, it's usually just an overnight temp...I work regular 9-5 hours). But we do have rainy seasons, so wet traction is a must.

Any recommendations?

I really don't plan on going outside the stock power envelope, at least not while the car is under factory warranty. So it will be a while before I do any mods to increase hp.

Do you need the tire to last? Do you have a budget?

My recommendation it to go 275/40/20 all around. You can go up to to a 315/35/20 on the rear but you will need a wider wheel (10").

As far as tire brand goes, something like a Michelin PS2 or the A/S 3 will probably suit your needs. Even though the A/S 3 is all season, it has better wet and dry performance than the PS2 Sumer tire. that means you get all of the performance and still retain the ability to withstand the rare days when temps go below freezing.

The biggest issue you will face is getting the tire you want in the size you want. The PS series doesn't come in the 275/40/20 size so you have to decide what you want...optimal size or optimal performance.

I split the difference and went with the Continental DWS in 275/40/20 size and I'm very happy with them overall.

 

[Sammy123]

I'd like the tires to last at least somewhat, especially since I expect them to be more on the expensive side. I don't really have a set budget, meaning I'm willing to pay whatever premium to get the traction and wet weather performance along with tire life, but I'd prefer to outfit the rear tires first.

I went to tirerack and didn't see the AS/3 in 275/40/20. Does that size exist for that tire?

Is there a general consensus on what's good for these cars in that typical 275/40/20 range?

Also, assuming the same brand tire, is there a difference in traction between 245/45 tires compared to 275/40? I've read the 275/40's are close to the same as the 245/45's, not sure if that is true or not.

Your size calculations are correct. Another thing you have to understand-with the power these cars make you can't bank on just mashing the gas pedal, hooking up and going so there's always foot discipline to factor in to matter what size tire you get.

I'm with @Ddaddy on going 275/40 all around. That way you can rotate and still see a noticeable difference in how well it'll hook up.

I agree! You can not mash the gas with this kind of power. 275/40/20 are the way to go, but foot discipline is the best bet no matter what you have out back!

HOw are the DWS's sidewalls? Handling? Would you do any light track events with them?

 

[AvsBest]

I have nitto motivos on the stock rims(yes they are 9 inches on the 12-14). 245 up front and 275 on the rear.

My buddy has 295 in the stock rims and he says it hooks up real nice (not the nittos though)

FWIW I used to run 295/30/20 (Nitto invo) on a stock 9in rim. What you lose in sidewall outweighs what you gain in width. My current 275/45/20 rear setup (that's basically lower end goodyear tires compared to invos) hooks better than the nittos ever did.

Not to mention the sway from the tires technically being too wide for the rim was atrocious. It felt like I was handling a boat when switching lanes on the highway.

Some guys have even gone as large as 315's on stock 9in rims (rear only)

They are pretty good all around. The turn-in is predictable and the lateral sway is consistent. The wider 275 make a huge difference in cornering performance.

They are good enough that I would track them on a road course with the only caveat being that the tread tends to begin losing grip a little when temps go above 95° F and the asphalt becomes cooking hot. This was far more noticeable when I was running the 245/45/20 than the 275/40/20, but it's still there.

On good pavement with temps between 70-80° F, these are pretty darn good shoes!

Oh yeah, they do very well in the rain.

I'm currently running the 245/45-20 DWS Conti's... I do like them very much, however it was a mistake not getting the 275s. While the tires are night and day better than the F1 summer tires I had before, the brute 6.4L Hemi still lights these things up so effortlessly. Often without really even trying. Overall a very nice tire though. I will definitely buy another set when I cook these off my wheels haha.

 

[Sammy123]

So I see you guys are running 275/45/20 as opposed to 275/40/20. Isn't that out of spec for the 20x9 wheel? Are there any considerations to take for the 45 tire?

I run the DWS in 275/40/20 size. The shorter sidewall keeps the total wheel diameter the same as stock and improves handling.

Running a 275/45 will increase total diameter by just a little over an inch and handling won't be as good as a 40 series.

 

[msv2015]

the sway from the tires technically being too wide for the rim was atrocious. It felt like I was handling a boat when switching lanes on the highway.

So just to clarify, is this the kind of driving feel you would get from 275/40/20 tires put on stock 20x9 wheels? And the R/T 20" wheel is also a 9 inch wheel right?

Thank you.

Not entirely sure a 275/45 would fit on the front without some rubbing happening.

 

[Sammy123]

I hear alot of good things about the Michelin AS3's, however it doesn't appear to be in the 275/40/20 size. How are people putting those on in the 20x9 rim?

On tirerack, the Continental DWS have a pretty good treadwear rating but single A traction rating. Florida has too many heavy rain days during the rainy season to skimp on wet traction.

The Pirelli P Zero All Season actually looks like the better tire, it has better traction (AA) rating and higher treadwear. I have to take another look at my current Pzero tires, I think the prior owner put on the summer version of this tire and just wore it out, that's why it's way too easy to spin the tires. I know 470hp is alot of power to put through tires, but it shouldn't be spinning more than my prior SRT4 lol, which had pretty good grip in 2nd gear with just over 300whp going through the front wheels (215 Avon tires).

 

[Sammy123]

So I settled for the Toyo Proxes 4 Plus in 275/40/20 for the rear tires. They were $218 shipped from amazon for each tire, not a bad deal I think.

 

[rob-2]

How do you like them? Always drives me nuts to have mismatched tires.

 

[Beach Goat]

My 6.8L 600hp GTO (with 3.70s!) had 265 Dunlop Direzza Z2 star specs on the back, and let me tell you, I NEVER had traction problems. They are by far the best street tire I've ever run, and I've run half a dozen of the big name brand summer tires.

They are fantastic in the rain, and lasted a long time too, about 20,000 miles. I'll never put another summer tire on my car.

I loved the star specs z1's. I could never get more then 6k out of the rears, 255's though. Best performance tire I've driven. Got tired of buying tires several times a year.

How did you ever get 20K?
