you will be fine, i had no problem switching to 18 inchers, like someone said, the difference is so small, you will not notice it.

Just wanted to say thanks to everyone for there input. I wasn't too sure about it at first, but a lot of people have been telling me that the tire sizes are almost the same, and that it should be ok!! Thanks again everyone!

Yeah, the tire size calculator is wonderful.

I have a 295/35-18 tire on the rear, calc comes out to be 1.7% slower... which seems just about right. a 295/30-18 would have been 3% faster, so I just went with the 35 because it's closer.

Edit: oh, and no changes. Speedometer is still so close to correct it doesn't make a difference.
