Just picked up an 07 SRT and the 255/45's are on the front and the 245/45's are on the back...Is this the way they are supposed to be??? I have a set of Charger SRT wheels with the same tires but i ran the 255's in the back...I'm confused...:confused:

I imagine someone rotated the tires not knowing they were staggered....

wider should be on the back..

When I got my '06, the 245s were on the left and the 255s were on the right.

LOL, could you feel the angle at all when you were driving??? i could feel how different the steering felt with the larger tires on the front...

No; I actually put 900 miles on it before I noticed (by looking at the tires one afternoon). Still I was worried about alignment issues.
Took it to NTB immediately for the swap (no charge, thanks guys!) No harm done though. All is well now. 3825 miles so far. She's the greatest car ever:biggrin:

Bad rotation

It is surely backward.

Jeez, this is getting all too familiar lately. I think this is the 2nd time I've seen this posted here and it wasn't all that long ago. Someone even had a combination of F1's and RSA's on their car. Might be worth checking that little tid bit out too. Maybe you got the other set...haha. Everyone who's said 255's on the rear and 245's on the front is right.

Now if you wanted to go with 255's front and rear that's fine even though the SRT Engineers say not to, plenty have done it.

I had it taken care of today...I knew something was fishy especially when braking from speeds above 45, i could just feel it...I got out and checked thats when i noticed 255/45:pat: what the hell is this? so i check the rear tires and they are 245, so the tires were probably rotated at the dealer before i picked it up, and the person who did the rotation wasn't up to par on the rotation procedures for a SRT with staggered fit ment tires. And they are all F-1's, I have the exact same set of tires on Charger SRT8 wheels and i always ran the larger tire in the rear.

at least you only drove yours 900 miles like that....i didnt notice mine till i was about to buy a new set of rears...since the tires were put on wrong i burned out one 245 and one 255 i had to replace all the tires so i went to 255/45/20 on all four...and i didnt feel the difference in the ride...go figure:pat:

LOL. I got all 245s ;)

There shouldn't be much of a diff really, 245 vs 255 is a width difference of 1cm, right? Now if you were running 45 series tires on one side and 55 on the other, that'd be freaky!

Actually it's a lot greater difference than that. The "45" sidewall is a percentage of the treadwidth.

In other words:

245/45/20 is 28.7 inches tall with a tread width of 9.6 inches (245mm).

255/45/20 is 29.1 inches tall with a tread width of 10 inches (255mm).

Ya know, looking at what I just wrote, when you convert inches to cm (2.54cm = 1 inch), you're figure is not that far off.
