That's the same size and offset I'm using on my truck. No rubbing or other problems.

Would changing the rim offset cause rubbing. I've seen offsets from +18 to -18. Even if you only level won't a positive offset bring the tires in?

I'm running a +1mm offset and my tires / wheels stick out slightly.

I went with the Rancho Quick lift and I'm running 34x12x18 BFG KO2 tires on mine with no rubbing. Actually had them test fit the 35s, but it was too tight of a fit for me.

Some don't have signatures so I'm wondering what engine & gears everyone is running with the new & larger tires? Also what effect they had on your MPG?

Spamfritter

3.31 gears, 3.5L ECOBOOST. The level didn't do ,uch but the wheels and tires weigh significantly more than the stock ones. My mileage drooped from 16.9MPG (average) to 14.3MPG (average).

Have you had any issue with airflow with your bull bar?

Spamfritter

Nope. Temps are all still fine. I haven't had any trouble, even while sitting in the Texas sun in heavy traffic.

im new here just got a 2015 xlt ecoboost. i came from an 06 gmc sierra denali i had 3" torsion bar lift and 3" body lift. I ran 35s and 2" wheel spacers. I loved the look of the tires outside the fender lines. looking to run 33/12.5r18 on stock wheels. would love to run 2" spacers too but not sure if ill rub. Has anyone run this setup and what kind of luck have you had?

follow up to my previous post. stock 2015 xlt can fit 33/12.5r18 on stock height with no rubbing. i leveled with 2.5" coil spacer and installed 1.5" wheel spacers front and back. no rubbing at all
