Question
Can different wheel materials affect TPMS performance?
Answer
Yes—steel or heavily coated wheels attenuate RF signals, reducing ECU reception range.
Explain
Thick steel wheels (common in trucks) or chrome-plated rims absorb 30-50% of RF energy; wheels with internal damping foam (luxury models) further weaken signals. Alloy wheels with thin walls perform best. CHEPQ diagnostic tools measure RF amplitude (RSSI) to quantify signal loss and recommend wheel material adjustments.
