Wheels 22" Chrome upgrade from the standard wheels from the factory The tire bead where the chrome meets the interior alloy metal corrodes. Thetires start losing air pressure. The tires should be 35 PSI. The front tire dropped to 23 PSI making sterring pull to the right. This is a problem with all 4 tires on the 2018 Chev Suburban Premier. I need to check tire pressure weekly
Rim corrosion resulting in loss of air pressure. The inner portion of the rim is corroding causing the tires to loose pressure. Depending on the amount of corrosion this could lead to a catastrophic failure at some point due to sudden loss of pressure. I took my vehicle to a tire shop thinking there was a puncture causing it to loose pressure. The manager explained to me that the pressure loss was due to corrosion of the alloy rim and that it is common with Chevrolet vehicles with factory alloy rims. The only solution to the problem is to have the rims possibly refurbished or replaced.
