Im looking to purchase some new tires here soon. I want to run a 275 in the rear. Just wanted some opinions on what to run in the front since I am awd, or if it would be better to stick to the stock size all the way around.

if you go 275s, do 275 all around. if not, do 265/50 all around. those work well too

I was gonna go with 275/45's all the way around because they were cheaper. Then at the last minute the guy at discount tire said he would do the 255/50's (stock size) for the same price, so that's what I did. I would stick to the same size all the way around though.

Thanks. Im stock height in the front now, looking to order the lowering kit at the end of the month to go to 31.5. Think 275s will rub pretty good?

275/45R20's will in NO WAY rub... they are just .2 inch shorter than stock, and depending on the brand, either the same or 1/4 inch wider into the wheel well.... They will not rub even if you lower it... unless your riding on the frame, then you might touch the fender...

Would the car look strange with 275/45/20 in the rear and stock 255's up front on a 2WD?

I would do 255/50 in front and 265/50 in back... you could do 275/50 in back, it's 30.9" tall, but the cheapest tire in that size is $235 each...

you could also do 265/45 in front (29.4" tall) and 275/45 in rear (29.8" tall)...

The Hankook Ventus AS RH07 comes in those sizes, and is $117 for the fronts, and $121 for the rears (on Tirerack)...

They are ranked 3rd in the Crossover/SUV Touring All-Season category with good scores in all the categories....

2wd or AWD can do a staggered setup with 20x8/10s and 265/50/20s and 295/45/20s

Get the 275/45 spec-xs if u care about tires lasting a while since they have a 420 treadwear. But for just sticky tires get the kdws

KDWs have pretty good treadwear at 300. It isn't like they are 150 or anything. I don't care for the spec -x because the tread design throws rocks.

That's true but u can't really compare a tread rating of 420 to 300, the difference is almost the same as comparing the kdws and nt05s together since the nt05s are I think 180. And the kdws would outlast those by a lot id think

That isn't very scientific. I'd say the drivers foot will have more to do with tire life then the 120 difference in tread wear rating.

Don't get too hung up on treadwear between two manufacturers. A treadwear of 300 form one company will be different than 300 from another. It's a gimmick.

Well I hope it works out because I got 255/50/20's up front and purchased the Kumho Ecsta STX KL12's for the rear in a 275/45/20.

Great there is a 1.2 inch difference between the two tires the wrong way! Ugh hopefully it doesnt look too bad.
