Difference between 275s and 305s for straight line performance?

[Devcom15]

I saw a thread for this in comparison for daily driving and comfort but not for performance. So the Charger is on my short list for the next car which would be third car since we are not trading in the other two. I am thinking about 275s because I am thinking less rotational mass and since its AWD I do not need to worry about traction issues on launches and might do better in rolls and top end when on a runway track or dragstrip. I have a Camaro that is the other reason I am considering the 275s since the Camaro is basically the Corner carver and if I do hit some twisties on the street with the Charger I think (correct if wrong) the 275s can handle it since I live no where near the Tail of the Dragon.

I would like to hear experiences from you guys though that have driven the Charger with 275s and 305s and even from those that have driven the car with both. I am in the planning and research phase now with a maybe lease or purchase time of end of this year or sometime next year so I am in no rush these kind of things I take my time with so I have the least chances of regrets later.

I have 275's and no issues and its a quiet tire with great handling in my opinion

Tires being the same, a wider one will always have more traction. I went with the 305 for a lot of reasons. I am still shocked how they can offer the 245 on the base EV which is even heavier. Go to Tire Rack and see for yourself and you'll learn a lot there.

Compound > Width every time.

There are 1500hp cars running a 275 series tire in drag racing for example.

A 200TW (normalish "sticky" street, something a "corner carver" or autocross etc guy would want to run) tire in a 275 would typically out perform a 380tw tire in a 305. Width is not everything.

True, which is why I said tires being equal. Since we can only get All Seasons, we're kind of stuck for now. On the 2027 details, I still don't see a Summer Tire option yet either.

With AWD and those power levels, and weight, I doubt you can get the 275s to slip straight line (normally). On my Daytona, reasonably normally quick acceleration, the 305s in the front will squeal on demand, never the 325s in the rear. I bet if I swapped them, same thing would happen. With the Sixpack having torque split from 1 motor, I would think the rears would keep the traction straight line.

I've only had my Charger for two days so I'm going easy on her until the 500 mile break in.
But if it's anything like my Durango 392 was, you'll get absolutely zero slip/spin on full throttle standing start acceleration because both are AWD.

Now cornering is something else altogether. Given the same tire compound, wider tires should always have greater cornering limits.
I was specifically looking for the smaller 275's with the Black Package because I wanted fully black rims ("Blacknoise Aluminum").
If you get the wider tire option, the wheel color changes to a more grey color ("Luster Aluminum").

PLUS, depending upon the ride harshness, the bigger ones will allow a tad lower pressures to support the same load. I ordered the 305's w/o hesitation then.

Thank you all for the replies and I appreciate the inputs. I am in agreement with the AWD there will be no slips or traction issues with the 275s. As far as ride harshness goes I don't think it will be an issue if the Camaro doesn't bother me neither would the Charger regardless of tire size. One thing I do think though and wanted your opinions on as well though specifically from a roll I do think with the 275s with less rotational mass they would do slightly better than they 305s and by slightly maybe a tenth of a second better. Or am I overestimating that? My goals for this car is straight line performance since my Camaro would be the Cornering car for me and to also be a winter driver since it would be better than the Camaro as well in that regard.

Yeah, you're way over-thinking this. A few pounds on 5000 total are meaningless. One thing that wasn't mentioned yet was the traction control intrusion. The current one is almost non-existent.

One thing I noticed on my car with the 205 the ride is a bit harsher than my EV charger I had.. Totally different tires on EV.

Maybe the extra 1000#?

 

[aceinspp15]

Nope EV has an easy roll tire can not recall what the tires are but sure was quieter. Later RJD

 

[baabootoo12]

That'll do it.

I have the 305s and the rears will spin even in AWD on dry pavement if you get on it even rolling 30-40mph. The rear easily get loose with spirited driving in rwd mode of course.

You don’t always feel the wiggle because the car is so big, but the slip gauge in PP will show the wheel spin.

Hagerty's comparison test of the Daytona Charger Scat Pack reveals it does a 200 ft long front wheel burnout.
And it still managed to turn a 3.2 sec 0-60 mph and 11.6 quarter @ 119 mph.
With the 6 Pack Scat Pack, they got 3.8 sec and 12.1 @ 116 mph. Not bad!

Yup, can't beat AWD, even with 1000 horsepower!

I have complained about how Hagerty "tested" the Daytona Scat Pack. This is a DRAG RACE, right? Then WFT are they doing with the car in TRACK MODE??? Then comment on how it did a 200' front wheel burnout? Also, for those not knowing all about the Daytona, unless you hit the PowerShot button, you don't have full power in Track Mode, only Drag Mode has full power available by default. And they clearly have Launch Control set to max, like for a prepped track with sticky tires.

Then you get the Chuclkeheads at Edmunds doing a U-Drag complaining how it was harder to brake and turn in, while in... DRAG MODE, yeah, you don't say? Plus it was in the lead, so going faster, it would be harder to turn.

Track Mode, powershot at launch, full power, then best setup for cornering/braking.
Eh either way, it still won both.

I like people who are sticklers for details/facts. Good catch!
That had me wondering what the different testing groups got with the Daytona Scat Pack:
(0-60 / quarter mile)
Edmunds .......... 3.6 / 11.9 @ 116 mph
Hagerty ............ 3.2 / 11.6 @ 119 mph
Car & Driver ... 3.3 / 11.7 @ 119 mph
Motor Trend ... 3.3 / 11.7 @ 119 mph

That's pretty consistent.

I got 11.4 @124! On a track with timeslip. Drag Mode, no Launch Control, just rolled it on quickly.
