unfortunately I didn't know the staggered setup would mess with the AWD.
I just got it put on and now the AWD lights blinking when I drive..


My wheel setup are
19x8.5 +35 front
19.9.5 +40 back


tire sizes are
245/40/19 front
275/30/19 back


Can someone please help me with the correct tire sizes. The back setup is clean af on the car. My front is larger than my back tires, I'm trying to figure out the correct front tire size to help with the AWD problem and flush out with the back tires.

You need one of these combos.
225/45/19F & 245/40/19R
235/45/19F & 265/40/19R
235/40/19F & 265/35/19R
235/40/19F & 275/35/19R
245/40/19F & 275/35/19R
245/40/19F & 285/35/19R
The outside diameter must be within 1% of each other.

Yep^^^ replace those rear tires w/ 275/35/19s and you'll be OK, if you didn't do any serious damage already.

Thanks you for the help! Damn gotta replace rear tires? Was hoping front.

Driven on them less than 50miles

Well you could run 235/35/19 front w/ your current 275/30/19 rear but your overall diameter is quite a bit smaller than OEM, well over 4% so while your Front to rear variance is almost zero that tire being 1.2" shorter may cause other issues, so replacing the rears would be the best option. Maybe you can find a buyer for your 275s so it won't be such a hit.

There's no one better than Brad to help you suss this out!

I ran a staggered set up for about a year before I decided squared was my best bet on my X

Do I need the same tire brand/trend for AWD?
So you guys saying the 275/35 will not mess with the AWD? Need to be sure before I spend more money..

Yes it will work, or 285/35. The 285/35 is better since it is bigger and will wear faster than the front and the 1% size difference will get better not worse like with the 275/35. But either will work fine with your front tires.
