27.5" Tire too Tall for an '05 Outback?

Okay, so the stock 16" Tire is a 225/60-16 that stands 26.6" tall, and the stock Fitment for the 17" is a 225/55-16 that stands 26.9" tall. So clearly a 27" tall tire is no big deal, but is a 27.5" tire just too much? The tire I'm looking at is 27.5" diameter x 9" Width (same width as stock), thoughts?

I doubt you'll even be able to tell much of a difference between 225/60-16 and 225/65-16 tires as the radius is only 1/2 inch bigger. (half the diameter increase) To check for fitment turn the wheel all the way to the left and right and look for places that will rub. Usually suspension control arms, springs, and fender liners are what will get in the way. When you are looking make sure to check the top, front, and rear of the tire. If you are planning to run your car off road it's a good idea to check when the suspension is fully compressed and relaxed.

Again for a .5 inch increase I doubt there will be any issues at all, but some tire places will even mount the tire and let you try before you buy. (and some are so anal that they won't mount anything but factory stock size, so call first)

As long as all of the tires match, it probably doesn't matter what size they are, as the rotational circumference is identical.

Worst that would happen is probably some rubbing on the inner fender at full steering lock.

Hmm. It'll be cutting it close. 215/65R16s will fit 2005+ Outbacks, but a 225/65R16 might be too much. The 215/65R16 Grabbers have a larger diameter than the stock tires but are narrower, which helps to avoid rubbing at full lock. 215/65R16 Grabbers like mine are VERY close to rubbing.

Our 235/55/17 would be 26.2" diameter. At full lock, the fronts come close to the Tupperware at the front of the wheel well. So you might rub a bit when turning.

May I suggest you go to page 2 of the attached link:
http://www.carbibles.com/tyre_bible.html

key in the details of your current tyres and then compare the data of the new tyre...
Cool Link, lots of great information. I'm not sure why the suggestion to visit though, as I know the existing tire size, and the new tire size, as well as how to calculate them (though the manufacturers actual specs tend to vary from the calculated ones)..

Hey OhBe1,

A 235/55/17 calculates to 27.18", did you mean to say your 235/55-17 is 27.2" tall? The Stock RE-92A in 225/55-16 is 26.74" calculated, and 26.9" (manufacturers specs) overall diameter, so that would mean there is very little clearance tolerance beyond..

I'm guessing the additional .25" looks like it would be just too much to accommodate without rubbing given what you see with your 27" tall tire (the General AT2 in 215/65-16 is 27" according to manufacturer's specs)
