I'm going to install a 2" leveling kit on my 2014 Silverado, and I'm not sure the maximum tire size I can go without any rubbing. I'm thinking 285/65's. Any suggestions? My truck has 20" fuel wheels. Thanks in advance.

I had 285's on my 14 Sierra with no issues. I wouldn't have gone any bigger due to rub issues on the air dam.

Oversize tires are usually much heavier than the tires that come stock, the extra weight and height of the tire will affect performance. The taller the tire, the higher the gear ratio will become. Larger tires will also have a larger rotating mass due to the increase in weight. Both of these issues will result in a loss of low end torque. Your engine will have to strain harder to get the wheels rolling at the start. The smaller the engine, the more it will affect performance and put a strain on all components not to mention up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, which will cause it to travel more distance per revolution than the original equipment tire.

I have 285/65r20 on my '16 Sierra with 2" level and airdam removed.

I love it. I would do it again with a heartbeat. I did have to ziptie the inner fenders back for clearance.

Performance slightly suffered. MPG slightly suffered. My speedometer was off and it was recalibrated with a diablo programmer.

I am unsure if it'll fit with your wheels. If your wheels have the same backspacing as the factory wheels, then it should fit ok. If your wheels stick out a bit more, it might have rubbing on the inner fender.

Thanks for the pics. I just placed an order for BFG all-terrain tires in 285/65 size.
