    I believe Redline, Premier RS, and maybe Hatch RS come with 18s.
    The LT sedans, at least 2016-2017, came with 16s, Goodyears on most, Hankooks on RS, except my fleet ordered 2017 RS has Goodyears.

    I suspect the short runs of less than 10 minutes are killing your fuel economy. The engine never gets a chance to warm up. Take it out on a road at 55 MPH and drive out and back for 30 minutes each way. Then see what the fuel economy reports. Also, to rule out a dragging brake, when you get back, use the back of your hand and gently touch each wheel. They may be warm but they shouldn't be hot - a hot wheel indicates a dragging brake.

    My 2018 Hatch RS was an LT model and came w 16s. I plan to upgrade but will probably only do 17s because I'm terrified of driving it around the city with 18s. Philly potholes are real man... haha

    Ride quality sucks on the 18's. I went up a sidewall size when I replaced my tires and it helped a bit, but the 17"s are probably an even better choice.

    Also, if it makes you feel any better, this was my last top up before we head to the beach this weekend. 100% city/gridded streets/gridlock driving. Saw highway speeds for maybe 15 miles on the tank.

    Haha yeah I figured. I think it's just something people get used to. Personally that takes a toll physically on me and the car so I'd rather not risk it. Plus like you said below, it adds even more the mpg game.

    That said I think if I lived in the suburbs or down south with pretty open flat roads, I'd definitely go oversize like that. It just looks so gooood.

    I am not saying I am in the same ball park, but when I first got my '14 2lt , the mpg slowly went down a lot..... like initial full tank was around 440 mile.... then after a while it was 379-400... and this was on 87 octane... and at the time I was delivering pizzas.. and this was all from may 2 of last year till this past march... and insert a change of jobs, and one drive into work and home of about 25 miles. And slowly my full tank went back up to 480 miles per tank on 87 octane... then I started using some 93 octane and bam!!!! I am over 500 per tank... I will say as with any car, short trips or stop n go trips are the worst for mpg

I've seen folks here with MPGs in the 30s and 40s... Yet I average at 22 and peaked at 28. No aftermarket items are installed on the car short of a subwoofer. Any ideas?
    Thanks!
    You only have 750 miles, it should get better after "breaking in". The short trips are a mpg killer as others report. I have a 2012 LT RS and get upper 30 on road trip, but my daughter(heavy foot)drives intown alot and she averages in the mid 20s. Driving style contributes a lot to mpg also.

    I think it might be what was said earlier about the DIC
    it will report the average gas mileage for the last 1000 miles if you have it set that way
    you won't see much change unless you set it to last 25 or 50 miles
    you change it via the steering wheel buttons - have to hit the center check key when the mileage display is shown
