What is the widest tire that will fit on stock rims on 2012 300 SRT. I would like to run 255-45-20 front and 275-40-20 on rear. Do you think they will fit and not stick outside wheel wells. Thanks for help.

You can run a 275 tire size in the rear with no problem. However, running a 255/45/20 is 29.03 in diameter and 275/40/20 is 28.66 diameter. Think you will be fine with that setup.

I just put on the 275/315 Vredestein combo on mine with no problems.I'm in texas also and it works great if that helps..

275 front /315 rear will work with stock tires. The 315 rear may not work on the rear if you go with an aftermarket wheel with a different offset.

I run a 245/45 front and 275/40 rear set up right now and like the way the car handles with that stagger.

^^^I ran the same for years and through two different brands of tires. It works great and gives the car a nice look.

BUT... just put on a set of Michelin Pilot Super Sports and DAMN! These are some sticky rubber. Absolutely amazing, quiet, smooth riding, and a 30k mile warranty to boot.

Running 275/35/20 and loving every minute...

do changing to any of these size make the speedo off? i want to get new front and rears..like the staggered idea...just dont want any speedo issues...

You won't have any speedo issues with the sizes mentioned.

Anytime you are changing tires as long as you stay "near" (within a few tenths) of the stock tire OD the affect to your speedo will be negligible..

Dude, it depends what look your going for, are you going for a Fast Hod Rod look, then go with 275/315 rear.. Same diameter as stock
are you just wanting to change tires just to change tires, then go with 245/275 (Maddog).. Either way, your speedometer will stay the same..

Here is mine on 275/315 and I have a small spacer in the rear...

I am selling my tires, Nitto NT05 275/40/20 and 315/35/20 if interested, have around 1100 miles on them....

I am curious maybe the question has been answered so apology I had a 2010 Challenger SRT8 with OEM Staggered 245 45 F / 255 45 R not real sure what that accomplished not much of a size difference but could not really rotate that set up. I was able to put the 255 45 on the Front so both same sized and made rotation possible. Question I have and sorry if that has been answered above - seems the 255 45s for sure work on the rear but will they also work on the front for a 2011 - 2013 300SRT8 or does anyone have 255 45s on the front? Thanks and apology if duplicating

You really fit 315s on the stock 20x9 tire? Can you post a shot from the back.
I'm thinking 285 myself but I've got to see that from the back

I ran 255/45 x 20 all round on my 2010 300c without any issues the wheels were 20x 9 Challenger SRT reproductions and loved them,with a 20+ off set

Cheers

I'm running 275's on the back and stock 245's up front. I personally would not go wider than the 275 on the stock rims.

 

[stevesrt8]

^^^and the reason for that is that there is a max recommended size for a nine inch rim. BINGO -it's 275.

A larger tire may or may not fit. Tire sizing varies by mfgr, more than you think. Plus if it bows at all you could have a dangerous setup.

 

[TC300C]

I had 315/35/20 on Magnum SRT Rims(20x9) rears, they bow slightly which wasn't too radical that I thought they purposed a danger. Unfortunately I don't have any pictures of it any more.

are you running 275 35 all the way around?

 

[MAXSRT]

Can anybody post a photo of 315's (or 275's) fitted to 2nd gen SRT8 with stock SRT wheels and standard height?

To gauge how the extra width looks in the rear?

Thankyou in advance.

Old thread back from the dead.

I have a '12 300 SRT&.

What I see here is you guys are putting 275/40/20 on the front and 315/40/20 in the back using a small spacer on the back only?

Do the 315's look like they're bulging out a little too much sides? God knows the 6.4 needs the 315's in the back.

just confirming before I do this, I don't want tires that Rub at all or look like a teenager stuffed too big of tires on rice.

Thank you
