and
275/30/19, circumference: 80.1"
wouldn't a 235 front be better suited with a 275 rear? 80.0 vs 80.1

I guess since so many people have 245 and 275 the difference is not problematic for the DSC.

Im Glad I found this thread...
Currently Im running 235/35/19 up front and 255/35/19 rears, all on staggered rims.

I think my rear tire size is affecting my DSC making it light up when (coming on/off ramps or taking freeway curve left/right at high speeds).

I had 235/35/19 front and 275/30/19 rears before with no DSC issues.

Thanks to this thread, I just purchased a pair of Conti Extreme Contact DWS size 235/45/18 to match the same tires I have in the rear sized 265/40/18.

Both tires have the exact revs per mile, and now my DSC does not kick in until I am WAY into the fun zone!

Woo hoo!!!!

The question that was asked multiple times in this thread with no real answer being given is whether 245/275 is better or 245/285?

It seems that the circumference difference between 245 and 285 is less, however going 245/285 means you have taken the relative stagger to 40mm instead of 30

Can we can get a more definitive answer here please?

I'd go with 245/275.

Increasing the amount of stagger is the opposite of good

great thread...what are your thoughts on 265/35/19 in the rear on a csl/zcp wheel?

Been running the usual 245/35/19f, 275/30/19r combo the last few yrs on OEM CSL's and as I'm due for replacing the rears shortly considering what this would do for handling/ride quality given the increasingly poor condition of roads around SF area these days. Just think a bit more meat in the rear sidewall would help from the quality perspective since these wheels are mainly used on the street. For the front id keep the same sizing. Ive run ps2's, T1R's, and currently the RE050A pole positions. Considering the RE-11's next to try something new...

So id go to running a 245/35/19f & 265/35/19r...and of course when the fronts wear out id pick up another pair of RE-11's for that too.

i have a question:

i'm planning on running a square set up of rear oem 19" rims, because the concavity just looks great. my question is, will 245(currently on my front) fit the oem 19" rims, without being too stretched? the tires are toyo t1r if that helps, and also, are our 19" rear rims 9.5" or 9" ?

I'd stick with the recommended 265/30/19.

It's only 1 cm off 255, I think you'd be okay. I think concavity is a dumb reason to run rear wheels in the front, though...
