20 inch Tahoe wheels

One wheel cannot go on another if that is what you are asking. You could use 20" wheels if you use appropriate sized tires.

Thanks, let me be more clear. I would like to replace the 18 inch wheels and tires with 20 inch wheels and tires. I guess the bottom line is will an LTZ 20 inch wheel and tire fit on a LS Tahoe that came with 18 inch wheels and tires.

Can I put 27565R20 tires with 20 inch trims on a 2002 chevy tahoe.
