Pay attention to TPMS caps

Just like on any vehicles with TPMS that features aluminum valve stems, do not install a chrome or chrome-plated steel valve cap on an aluminum valve stem on a Hummer H2.

Contact between the different materials will result in galvanic corrosion which will seal the cap to the stem, potentially fracturing the stem when attempting to remove the cap.

Use only plastic or aluminum caps on an aluminum valve stem.
