Default 2012 4:10 gears 35" tires

I've searched with no luck to see how this combo is working out, Pentastar, auto, 35's. With my 2012 rubi on stock tires I'm turing around 2400 at 65 mph. 3000 at 80. Just wondered if the auto pulls the 35 easily and what rpm's your looking at at 65 mph.

A picture is worth a thousand words they say. My speedo is off about 5 mph. But you can see by the GPS on the left what I;m running.

An auto will definitely need to be re-flashed to deal with the bigger tires. I don't mind 4.10's with my 35's and the 3.8...but I have a 6 speed.

Thanks for the input but I'm specifically interested in the pentastar the new 5 speed and 35's. I had an 08 3.8 and an auto with 3:73's. If I left the overdrive off it did ok but even then I hated the way the auto was designed.. After driving my 12 I'm thinking 35's with 4:10's may be a perfect combo.

I was under the impression that the new engine/transmission combo, the new Rubi 4.10's were basically the equivalent of the older 3.8's running a set of 4.88's.

And considering that the older engines could handle 35's fine with the 4.10's, I'd say you'll be more than fine with the new engine and a set of 35's.

from what i read the ones that have them love them ! the ones that dont are ordering and ones that hate are driving 07s wich was one of the worst years ever from what ive seen ! so go figure ! were all in this togeather im going for the 12 over my 11 ill miss it but i bet ill like the new one every bit as much if not more ! new anything is great unless you get a lemon and then you file under the law s and then go to another brand if they dont want to work it out ! i found thats the only way to go .! filed lemon law once during the 80s and ended up being on the good end of the stick ! not the shitty end ! chrysler new it was a faulty truck and finaly gave me my full refund ! years later id do it again if i got a bad one !

Not sure any clearer way of putting it. I'm only interested in what I asked in my first post. I really don't need the thread hijacked by a 3.8, a 6 speed, or 32 inch tires. I'm really just wanting input on a 2012 with an auto, 4:10's and 35's.... Thanks...

Nice pic. thanks.. Hows the performance? Does it pull the 35's with little effort?

I haven't read a comparison to a 3.8 with 4:88's. That's encouraging... I'm not lifting and adding the 35's until after the Illinois winter coming up. I might as well keep the salt off the new suspension this season, It will eat the paint right off the coils and arms.

I have 34s on a 2012 rubi with 4.10 auto and it runs great. My speedo is 4 mph off but no issues with power. It still pulls about the same a it did with the stock 32s. I will fix the speedo when Superchips finally releases programming for the 12. Feels much stronger than my 08 manual running 4.88 gears and 35s.

maybe you need reading glasses i was talkin bout the 410s on 2012
dont be a wienerhead all your life , it wasnt a hijack but seeing you think it is , ur obviously made of oscar myer, dont know anyother way to make it any more clear to you .
I couldn't make heads or tails out of your post. You went from telling me about 32's, talked about the nitto's a 2011 and a lemon.. Basically nothing I requested in my post.. You seem to be rambling.. Anyway I'm sure you was thinking all that was useful. Thanks..
