Yeah. Stock size is either 215/70/15, 205/70/15 or 225/60/16 - diameters of 26.85, 26.3, or 26.63 inches, respectively. 235/75/15 would have a diameter of 28.88" so over 2" taller than any of the stock sizes. If you were to install them the car would not only ride 1" higher than stock, but your speedo would be about 7-8% too slow for your actual speed (e.g. speedo says 60 but you are actually going 65).
