If the rears are 255/35r19 can i run 245 35/r19 without any issues?

I wouldn't with an AWD car. you want the difference in tire size to be less than a 1% difference from eachother regarding "Rolling diameter". Otherwise you are more likely to have 4x4, abs & DSC error lights.

Try messing with this below:

https://tiresize.com/calculator/

click on tire comparison and put in the two different sizes you would like to use for front and rear and if the diameter is less than 1% you'll be fine.

for example I have 235/35/19 and 265/30/19 difference= .8%
