Default Tire Question

My current tire sizes are:

245/40/18 (front)
275/35/18 (rear)

I really like the low profile "look" of the rears, so I'm wondering if its ok to do 35 series all around:

245/35/18 (front)
275/35/18 (rear)

Are there any disadvantages of this setup?

Should work fine, I don't forsee any ABS issues with a change in diameter like that.
Traction control... not so sure, but it's related to the ABS anyway. The NSXs are sensitive to big differences in diameter front to rear (TCS activates constantly), but I haven't heard complaints with the Lexus cars with TCS.

The only issues:
1) Slightly greater risk of wheel damage over potholes
2) Few tire choices in this size (Pirelli is the only one I can think of).

Unlike the poor Honda traction control, Toyota traction control compares the relative speed of the tires. No worries.

As mentioned, the negatives are poor tire selection, more risk of damage, and worse ride quality.
