Truck rims & tires too big for truck, rubbing in hard turn

I bought a used truck that has aftermarket rims and tires. I didn't catch it when test driving, but right front tire rubs the inside of the fender well when I cut it all the way to the right. It doesn't do that turning to the left, and the left tire isn't rubbing. What's the fix? Coworker mentioned a leveling lift kit would fix it, or do I need to downsize the wheels a bit. These are 20" rims.

Your truck most likely calls for 20” rims/wheels. Your tires/rubber are over size. Wear out those tires then replace with smaller.
Look into the leveling kit to explore all options.

Depending on how it’s rubbing you can maybe get away with wheel spacers if you just need a little clearance.
But once you get new tires then you should definitely get the correct size.

Stock tires and rims.

What kind of truck?
Front or back of the fender well?
Is it the fender well itself, or the plastic liner?
Exactly what aftermarket wheels (and their offset)?
There is a multitude of options to remedy depending on the exact situation. Trim the liner, wheel spacers, bumper spacers, full leveling kit, crank the torsion bars a bit (if the truck has them), new tires.
The rim size itself is nearly irrelevant, outside of the offset. The overall diameter of the tire is what determines the overall height of the assembly. You can have a 35" tire in a 22" rim all the way down to a 15" rim. Its still gonna rub the exact same, as the overall diameter doesn't change, just the "inside donut" for the rim.

2020 GMC 1500 AT4 w/ 275 / 60R20 Mickey Thompson Baja Boss tires, the rims have an offset to the outside.
Rubbing the back of the inside of the fender wall and the plastic piece below that.

Yeah, those tires arent wide at all but are 33" and will absolutely rub a stock truck. Is it completely stock or is there already a spacer on the top of the strut? Could you just trim fender?

There's no spacers or lift kit at all on it.

Your offset is what’s killing you.
I had 295/60/20 on stock rims on a ‘19 SLT and it didn’t rub.

I would think strut spacers should solve it. They are cheap and stupid easy to install, provided you don't mind losing the factory raked stance.

There is a bracket bolted to the front of the frame rail near the back of the front tire (behind the fender skirt). Turn the truck wheels all the way to the left, detach the fender skirt near the back of the tire then remove the four bolts connecting the bracket to the frame then remove the bracket. Repeat for the passenger side and you should solve the problem. I think the video in the link below is the video I used to figure it out. I didn't mess with the section in the front of the wheel well behind the bumper and I've got 35s

All this!!
The tire isn’t too big, relatively speaking- but just like when you add spacers…yuck…too much offset increases the scrub radius and you get interference like this.
If you like the look, and the rub doesn’t sound like it’s horrible, use a sawzall, cutoff wheel, hammer, etc to trim fender liners or smash pinch welds that are causing the interference.

Got a quote to install a leveling kit and re-alignment from CSC Customs. If there's still rubbing, I'll take that plastic piece off the back of the front fender.

There is a possibility that the previous driver replaced tie rods OR tried to straighten the steering wheel.
If you adjust the hell out of tie roads you can make the wheels cut waaaaay to far one direction while barely turning the other.
If your tie rods are set correctly then both tires will touch on hard cuts or neither tire will touch. You have only 1 touching. You need to get that aligned because you might not touch at all when turning sharp in both directions. If you do, then you can figure out best path… lift or smaller wheels/tires.

SO without knowing the OEM sized tires the obvious problem is the offset rims. The very best service you will get out of that truck will be with the standard sized rims and tires that the truck was manufactured to use. Anytime you put offset rims or lift kits you are changing the geometry of the from suspension and steering, Your stuck will not drive as well as when new. The tires and front end components will wear faster. It's just physics.
Now if you want to send about 10K you can hire someone to re-engineer the who chassis so it will liik better to someone that is not in the truck..
Some may not agree with me but keep this post. I will be right down the road.

tires too big for truck

Got a 1-3/4" leveling lift kit and an alignment. It looks good. Right tire isn't rubbing anymore, but left tire is now rubbing just a tad when cut all the way left. There are some short plastic mud guards that are sticking below the back of the fenders that it's rubbing on. I found a kit online that I can order to replace those mudgards with just a piece of plastic trim that matches the piece that goes around the whole fender. I'm going to try that and see if that will reduce all of the rubbing.

What is it rubbing on? If its only one tire its usually just the wheel well liner. It should be pretty easy to just go in an trim your wheel well liner to not rub on the tire when it is turned all the way.
