I recommend that you use this tire size calculator, and compare actual clearances that you have with the stock rim/tire combination to the proposed clearance changes shown in the tire size calculator for your proposed rim/tire combination. This should get you an initial estimate for your potential clearance issues. I believe that this would work best, if you did the level kit installation first, to establish actual clearances with the leveled truck.

Please note that I am not an expert at all in and lifting/leveling, so others on this Forum who have this expertise will chime in with their suggestions and perspectives.
Have a 2018 Yukon with OEM 20” rims. I was given a set of Fuel 20” rims that are 10” inside width lip to lip. I am also doing a 2 1/2”leveling kit on the front to level out the truck. I want to put new tires all around but not sure what size to use. I’m not wanting mud grips or any other type of aggressive tread, but a standard style tire for the road and highways. I am retired from Goodyear Chemical and get a huge discount on tires, just not sure what size I need, considering the different wheels. Any help is appreciated. Thanks.
