I have been looking around the web to find information about staggered tires. I will be getting some new wheels soon, and though I'm not sure which wheels I'm going to get, I know they will be 20x9 all around. I was thinking if I decide to go staggered I would do 245/45/20 up front and 275/40/20 in the rear. I don't want to go much wider than that because then the unsprung weight of the tire can affect performance.

My concern with staggering tires is that I will be going through them very fast. It seem that no matter where I dig online, I cannot find a consensus as to whether one can rotate staggered tires or not. Obviously it can't be done conventionally, but maybe side to side?

I also wanted to know what the life of my tires will be if I go staggered as opposed to the same on all four corners? How does tread life compare?

I am thinking about lowering my car in the future with the eibach pro or mopar stage 1 springs... Will 275's fit in the rear on an RT dropped 1.5-2 inches? Will the drop have an effect on my tire tread life?

Thanks in advance. I know I have several questions, and if you have even read up to this point I appreciate it!

You have a couple questions here but I will try to answer them all.

- Like you said, you cannot rotate them conventionally, but you can rotate them side to side as long as the tires you buy are not directional.

- Your tread life will depend on your driving habits and the tire you get. A soft summer tire with a tread wear rating in the 2xx range will not last you more than about 20k miles. A harder all season tire with a tread wear rating of 5xx should last you around 50k miles. The rear tires will wear out quicker if your spinning them a lot and the fronts will wear out very quickly of your cornering and driving them hard, especially if your alignment is off.

- I have eibach lowering springs and they do not seen to effect the tires as long as the alignment is true. If your shop cannot get your alignment in, you may need to buy adjustable upper control arms to get it right ( my Eibach springs lowered my 09 RT about 2 inches and I don't need adjustable arms).

- As far as the rear figment with 275s, I can't give you a honest answer, I know it will depend on your wheel offset.

There are a lot of people on this forum who know a lot more than me and I'm sure they will correct me if I'm wrong, hope all goes well for you!

Hey thanks a ton for the info!

I will definately be going with all season tires because I live in Oregon, where we get a ton of rain and not much snow. Temps are mostly in the 30s (Fahrenheit) at the coldest in the winter. Spring and fall are wet, and summer is dry. My main concern is being able to rotate them to get as much as I can out of them. I don't drive very aggressively, but I do like to have fun at times>.

I'm hoping my car will align with the eibach kit once I do it. The wheels that I am considering are all OEM from either the scat pack challenger or SRT challenger from 09-11. I'll have to take a look at what the offset is.

Yeah man no worries, glad I can help, obviously you will have to run a different size wheel on the back than what you run up front since your tire is wider.

I love my Goodyear Eagle Sport All seasons. They are awesome and super sticky for a 560 tread wear tire.

Would I? I thought a 245 and a 275 could fit on a 20x9? I may be wrong though:what:

 

[Ddaddy]

Why not just run 275/40 all around? It's what I do on mine.

Here is a comparison of my car with the stock 245/45 on all corners(top) vs the 275/40 all around (bottom)

Here is a rear angle comparison...

I suppose I could do that. Would there be an advantage (other than being able to rotate tires conventionally) to having them on all fours as opposed to the two rear?

The biggest advantage is in the handling. There is a reason SRT puts the same size tires on all 4 corners and on the Hellcat too.

Longer treadlife with the ability to rotate the tires plus better handling...the only question is why wouldn't you do it?

I see your point lol, I just like the staggered look but you may have swayed me.

Do you know if I'd have clearance issues with up to a 2 inch drop?

I doubt you will have clearance issues with a drop. Look at my pics and remember that my SRT sits quite a bit lower than your car does already.

Your clearance issue will be with those SRT wheels you are getting. You will probably need a 3mm spacer for the front wheels due to the wheel offset. Not a big problem, just be sure to get the hub centric ones. Speedlogix sells good ones that are hub centric.

Do you have to do anything extra to run that wide of tires? I have 235/55s on mine right now

 

[WideBlueEyes]

I was thinking you had 8 inch rims, 20x9 should be okay. I would check though.

Well, you need 20" x 9" wheels with the correct offset and possibly some spacers for the front but otherwise...nothing special needed.

The main issue in the front is clearing the upper control arm bolt so that the tire doesn't rub on it.

Not as of now, but I'm planning to be getting either srt or scat pack wheels
which will go 9 inches wide.

Yeah I believe my 18 inch stockers from the rt are 7.5 inches wide. I currently have 235s on them.

I remember being told about the spacers before so I will definitely do that.

Are the offsets for the scat pack wheels the same as srt's to the point that I'd need spacers?

No problems clearing the bolt with 275/40r20s. Depending on the wheel offset, its possible to have interference with the arm itself.

Running 275/40s up front is not a "no brainer." For starters, useful information here:

I believe the wheel specs changed for 2015. For one, the OEM SRT wheels are now 20x9.5" and the offset has changed from the 2011-2014s. The SP wheels are 20x9" - I've misplaced the offset numbers.

So in order for me to run the 275's up front I need the srt knuckle is what it looked like they were saying there? I'm not exactly sure, some said they fir and some said they didn't fit.

Or are they just saying that it won't clear the knuckle without the spacers?

If they won't fit even with spacers on my RT then I'll just go with the staggered setup of 245 front and 275 back.

I'm still concerned about the possibility of rubbing when I do (eventually) lower my RT with springs.

I guess the first thing I need to do is make my mind up on which wheels I want so I can figure out the offset and see what will work.

No, you won't need the SRT knuckles. You need the spacers if you are mounting OEM (not replica) SRT wheels on R/T knuckles.

That would be a good starting point.

Okay gotcha, thanks.

Ha it's easier said than done for me, but I think I will sleep on it for a day or two more and then just go with something. I think I'll be happy with any of the options that I put up on the other thread, and you gave me another option this morning that I liked as well.

If I decide to go with the scat pack wheels, I would imagine they have the same offset (since they are both from the scat pack and just from a different group).

Once I get the wheels, I'll decide on tires and think about lowering moving on.

Thanks for all of your help:bigthumb:

Often the OEM offsets are different from the replica offsets -- at least they have been for OEM and replica SRTs.
