I recently purchased a set of 17 x 8 wheels for my 75, and I am curious what size tire do I need for the inflated height to be

26 inches

27 inches

28 inches

Thanks

Are you trying to maintain the stock tire height?

I don't have the numbers for the stock GR70x15 tires, but:

245/60 R 15 is 26.57"
255/60 R 15 is 27.04"
235/60 R 15 is 26.1"

Hope this helps some.

Stock tire height is 27"
255/50 17 is correct height.
