I hope your not planning on adding more than 8qts oil??

GOOD video regarding the issue with the calipers and what to look for behind the wheel for proper fitment.

They're are some good reviews on both the AT and the MT. https://www.offroadxtreme.com/engine-tech/wheels-tires/tire-review-mickey-thompson-deegan-38-all-terrain

The Trail Boss Goodyear Duratrac AT tires weight 53lbs. I know when you go to a larger heavier tire it can affect ride and mileage. The Mickey Thompson Deegan 38 has a true diameter 33" and 34" tires that are slightly heavier by only a few pounds. Plus Deegan is a local MX rider here in SoCal...support local!! https://www.mickeythompsontires.com/light-truck-tires/deegan-38-all-terrain#sizes

Just bought these...Black textured and easy to install with another person. https://www.roughcountry.com/rc-gm-wheel-to-wheel-nerf-steps-rcc1980c.html?find=2019-chevy-silverado-1500-4wd-15759
