Tested, it fits my trx4m f150 high trail with stock tires, but with the wide rims I had to remove the front bumper to prevent rubbing. No glueing needed on the thinner rims, but the wider rims have to be glued or they will constantly de-bead. The wide rims give my F150 amazing flex for stock axles and a super wide stance. No guarantee it will work with other smaller tires. Printing with 100% infill adds good weight, and adding BBs inside add even more weight. One file is 1/2" wide and slightly offset, and the other around 1 3/8" wide and greatly offset.

Drill out each rim in order to allow tire to compress/decompress

Wider tire prevents sinking into mud, gives monster truck look, and make tire softer somehow. Keep in mind stretching the tire will result in a lesser diameter and will necessitate glueing.

Thinner tire helps greatly when sunken in mud and on side hills.

With my poorly adjusted printer, I was able to get decent results, but the tires do wobble a bit.

Pictured above is my stock (except for 3D printed parts & bbs as wheel weights) trx4m f150 with the wider rims. After installing these, the only thing I need to complete the build for my preferences and budget is crawl gears/stronger drivetrain for peace of mind.
