Yes you can with no problem. They will be a little bit wider and taller, but hardly noticable.

That's actually the size that should have been on your STi, and why your speedometer reads about 4% fast, Subaru's tire of choice (the Bridgestone RE070) isn't available in the US in a 235, only in a 225, so we got stuck with it.

actually they went with the 225/45-17 to impress the magazines with the 0-60 times ..... the shorter tire improves the gearing for acceleration ... the 070 was designed per Subaru's specs so, they could have said "make it in a 235" but they didn't

if they really wanted to impress the magazines with 0-60 times they woulda let us hit 60 mph in 2nd.

I'm glad they didn't though, cuz they would just mess up the rest of the gearing.

You want a 235? You already have one. Measure your RE070.

Hmmm, this is in direct contrast to what the Bridgestone rep told me...

While the RE070 225 may be as wide as an average 235, it certainly isn't as wide as the very same tire in a 235, come on now Jon.

Perhaps a better way of looking at it is that the RE070 225 might well be as wide as another brands 235 "upgrade" which is what the original poster is considering.

Now if you have a source for 235/45 RE070s...

Perhaps. Of course, in that instance you'd be right (like you knew you were before you posted), with the tread width being 8.7" wide, the 225 RE070 is wider than most 235's...just not the RE070 235 .

***knowing is half the battle***
Yes it is:
http://www.tirerack.com/tires/Spec.j...=Potenza+RE070
RE070 225x45x17
Tread width = 8.7"
http://www.tirerack.com/tires/Spec.j...1=yes&place=15
Yoko AVS sport 235x45x17
Tread width = 8.3"
http://www.tirerack.com/tires/Spec.j...1=yes&place=10
Goodyear Eagle F1's 235x45x17
Tread width = 7.9"

As Jon said - the RE070 is as big, or bigger than most 235s anyways.

... and I believe 615's are even wider ... ahem ... when their 235 officially comes out.

Falkens are always WIDE. Their 225 is virtually the same size as the Kook in 235

Will it be a 235/45 or 235/40? It would be great to have a truly high performance alternative to EVO tires in 235/45.
