Yes, you can run it. It won't be a big enough difference between the tires to affect the ABS or traction control. The 245/45/17 has a circumference of 80.7 inches and the 275/40/17 has a circumference of 80.6 inches. I'm running 245/40/18 on the front with a 285/35/18 on my car with no adverse effects. Although I only have ABS because traction control wasn't an issue on a 95, it's not enough of a difference to matter to the system. In my case, it's only .4" of a difference in size. You'll be .1" different.
