There barely any increase, why not go aftermarket wheels with a 18x8.5 and you’ll be able to run 255+
want to keep my stock wheels

Most people just run aftermarket wheels, but 245/40 will work just keep in mind your actual speed will be faster than your speedometer a slight amount. Also the increased side wall height. Don’t see an issue with the pro springs though

40 refers to the pecentage of the tire width as sidewall height. A wider tire with the same aspect ratio means more sidewall height.

245/40-18 is no problem at all... In the autocross world, we sometimes jam a ridiculous tire on stock sized wheels. Although the car was not lowered, all of the following sizes have fit on either 17x8 or 18x8 wheels with +45 or +50 offsets:
245/45-17
255/40-17
245/40-18
255/40-18 (slight rub at full lock with +45mm offset)

I run this tire size (245/40/18) with 18x8 Accord16 wheels, no rub, and the speedometers works fine.
