hey everyone. im in the process of buying new tires and heres my current list:
Front:
245/40/19s (stock size)
Rear:
275/35/19 OR
285/35/19
Does that sound good? or what should I tweek here? I want to have no ABS issues and my car is stock height. Should the rears be a 30 instead of a 35?

Front is 26.7"Originally Posted by Dagoon
275/35-19 will be 26.6"
285/35-19 will be 26.9"
Height-wise/ABS/etc; you are fine with either combo.
No, you don't want a 30 series for those combos. Way too small tire for that type of setup.

Height-wise, no they won't rub. I run a 26.9" tall rear tire with no height-rub issues.
Width-wise, depends on the width and offset of your wheels.

My rear setup is 285/35-19 on 9.5" wide +45 offset (just like you are describing). They did not rub until I added a full-size spare and one additional passenger and only on heavy dips or bumps and then they rubbed very slightly and very infrequently.
A 275 would probably give the extra clearance not to rub under these conditions because they are not as wide and not as tall.
I had my fenders rolled and slightly pulled and have no more issues. I also added a 5.5mm spacer to push them outward even further and they still don't rub.

So I looked through and found that 40 offset on a 19x9.5 will work up front, but the rim I am looking at is 41mm offset. I know I can get a spacer to fix that but was curious, would a 41mm offset not rub the front strut on a stock car?

It would probably be close, but you should be OK I would think.

I like them for the money. They came highly rated by several car magazines.
In my experience, they do well in wet weather. I run them from about April to Oct/Nov.
Cornering, they've been fine for this heavy car.
Their straightline, dry traction seemed better last year when they were newer but it's also not that hot out yet. I don't have a lot of miles on them and plenty of tread left.
They stick better in temps above 70 degrees. The hotter it gets, the better they grip in a straight line.
With consistent temps below 40/45, I would take them off the car as they are too slippery when it gets near freezing.
I don't find them noisy.
@ SLizzo: what's your opinion on your Hankooks??? I'd like to hear too and it would help out Dagoon.
