Im a very "think ahead" person and when my t1-s on my 19s burn out I want to try a set of Falken St-115's. These tires dont come in 275/35/19, only 27530/19. The oem spec for 18s are: (OD = Overall Diamater; these numbers all came off toyo.com and falkentire.com, both t1's and st115s have almost identical specs.)

225/45/19 ~ OD= 25.9
245/45/19 ~ OD = 26.6
thats .7 that the rears are bigger.

Now here is my current setup on my 19s
245/35/19 ~ OD = 25.8
275/35/19 ~ OD = 26.6
thats .6 that the rears are bigger.

Now if I went the rout of 275/30
245/35/19 ~ OD = 25.8
275/30/19 ~OD = 25.7
thats .1 that the FRONT is bigger, how does this affect VDC seeing the fronts
are in fact slightly bigger.

I also looked at 285/30/19 (t1-r comes in this size) and those are still 25.8 which still does not make the rears bigger than the front. I do however like how a 275/30 looks in back but i really would like to know how the car react to this setup. thanks, and sry for the long post

i'm running 275/30's in the rear and the vdc comes on during spirited driving. because of this. vdc (which is completely worthless IMHO), stays off at ALL TIMES.

 

I'm also running 275/30/19 and no problems with the VDC.

 

i was running 275/30/19 while i never had a problem with the vdc, i would never go with 275/30/19 again cause it's off by like 3% and it looked like crap. Having the car sit higher in the front than the rear with a larger gap in the rear to go with it. stay with 35 series tires.
