On my 2012 I have 245 front and 275 rear. I probably should have gone 255 in the front.

 

Here’s a picture of how it fits the wheel wells.

Where?

 

275/40/20's will fit with zero issues. Your rims will need to be at least a 9" which shouldn't be an issue being a SP.

I replaced the 245's on my SP with DWS06 275/40's.

Much better car now in every way.

 

No need. I'm not changing mine to 275's or maybe 305's until they need replaced.

 

You should drive on the 245s before you worry about it. If you're not driving it hard you'll probably be fine.

 

It's kinda of the direction I may go. Car is primarily my wifes and we take our RAM on trips. tks for the info BTW Hellraisn is what we ordered with a fairly number of options.

Leaning towards seeing how the 245 are a move to the 275's for replacement. Nice color -

Thanks.

I put 29k miles on the factory 245 RSA's. I wanted to get my money's worth from the originals.

That said, the first day with the 275's, I wish that I would have done it sooner.

Just my experience and thoughts.

 

I had no idea you could put 275's on the 9" wheel. I wonder how wide you can go with 9.5" wheel then, 285 or 295?

 

9.5" you can do 285/40-20

A Guy

 

The 245s are fine for moderate driving. I'm not trying to set records, so I may as well get my money's worth even if they spin a little easier.

 

Your car will drive fine with 245’s. When it comes time to replace them go with 275’s at that point. They will definitely work on your 9” rims.

 

I'd put some miles on them before upgrading up. Does it rain a lot in your area? I have 245's on my 2020RT and its no bueno when it's wet out, amazes me how they put 245's on a scat pack

 

I have 245s on my Challenger and have had no problems at all. All depends on how you control the throttle. Too much and it spins. Drive normal and you will be fine. I even got caught in snow in West Virginia and it was fine. Enjoy the new car.

 

Yep, the throttle can get you, and I knew how to handle it based on road conditions.

I had to, as I'm always in Sport Mode.

 

245 is fun on empty parking lot or in the track going sideways. Use the tires until they're gone unless aesthetic matter much to you. Those pizza cutter tires will actually save some drivetrain parts that's probably why Dodge put them on for warranty claims.

 

245’s are fine.

I’d rather have good 245 than a crap 275.

 

True, but I would rather have a good 275 over a good 245.

Got to compare apples to apples.

 

I agree, in an apples to apples comparison on my own Challenger I found a big difference in two different 245s. The stock RSAs would spin if I barely touched the pedal. The replacements are General G Max, and they have much better traction.

 

most folks comment that (if equipped with all-season tire) the Goodyear RSA-2's didn't feel all that "confidence inspiring". And after installing 275/40s on their Scat Pack "I wish I did this far sooner"

My day # 2 mod was replacing the 245/45 RSA-2 with 275/40s - I sold the take off 245/45s to a local member than needed new tires for their R/T and only had 245/45 tires as the only choice to fit the 20" x 8" OEM wheels

 

My 2015 RT came with the OEM Hyper Black 20 x 8 rims and 245s. I always kept and eye out for the OEM WRT 20 x 9 rims as I always liked these rims better! Recently I was able to buy some and thus I ended up buying new tires and upgraded to the 275s!

The grip on these wider tires is better and it definitely gives the car a more stout look! Here's a pic of the installed 245s vs the 275 wheel next to it, big difference.
