I think the main problem is that you have different profiles on the front and back tires making your wheels' diameter (height) different, which is a no no on AWD. Staggered setups are not recommended for AWD but acceptable to a certain extend and if done right (less than 5% difference and depending on the car) what everybody seems to agree is the diameter or height of the wheel NEEDS to be exactly the same in all the wheels in an AWD.

Way to fix it:

225/35/19 on the front
255/35/19 on the back


Don't just take my word, I'm not an expert, but maybe you can research on that a little more or tell the shop about this, I really think this is what could be causing the problem
If i put 255/35/19 instead of 255/30/19 the tire will be bigger. dont forget that a tire with 255/30/19 is bigger than a tire 225/30/19

Finally found the problem on my car. Problem was the nankang tires. Im now rolling on kuhmo and there isnt any wobbling. Also reduce my gap on the back with 265/30/19 instrad of 255/30. Thanks to Fcp warehouse they took back my tire with 200 miles on them. Thanks to everyone that helped me.

So many different tire sides and more I'm all confused. Anyways I'm getting 19" wheels and the guy wants to add all 4 even 225-35-19. Is this right or wrong. He's telling me to trust him that he knows what he's doing. All I need to know is if this will mess up anything in my car?

Anybody??? It's a 2012 is250 awd.
How about 235 35 19 with 10 offset all around. Is it safe for the awd system?
