In this modification experiment, watch as I successfully upgrade the donut spare (155/60 R17) to a larger donut spare (155/## R17). DIY at your own risk.
So does this get you to the regular wheel size or just closer? If just closer how close? My daughter has a 21 Sienna LE that has just the kit and I’d like to do the panel, carrier and wheel upgrade for her. She drives a ton and even if she couldn’t change a flat herself the option of someone helping her with a spare available would be great.
