The Mercedes Benz GLA 250 is equipped with a 3.5 liter V6 engine and comes with 18-inch OEM wheels and 235/50R18 tires. The recommended tire pressure for the front wheels is 33 PSI and 29 PSI for the rear wheels, with a maximum allowable pressure of 44 PSI for all tires. The lug nut pattern is 5 X 112mm. It is advised to monitor tire pressure regularly, especially during the winter months, as colder temperatures can cause a decrease in pressure by 1-2 PSI for every 10-degree drop. Alignment checks at a service center every 2-3 years are also recommended to ensure fuel efficiency and road safety.
Incorrect. The sensor will trigger an alert if the pressure is below 36 PSI.
The sticker on the door of my 2018 GLA250 turbo says the recommended cold tire pressure for all four tires is 44 psi. When my Mercedes dealer lowered the pressure to 32 psi, the low tire pressure warning light came on for all four tires.
Nobody, not even the Mercedes service staff, knows the correct tire pressure for the GLA250! My suggestion is to set all four tires to 35 psi to prevent the warning light from appearing, and slightly lower to ensure a smoother ride without feeling like you're driving a tractor.
The recommended tire pressure for the front tires of a Mercedes Benz GLA 250 is 33 pounds per square inch (PSI), while the rear tires should have a pressure of 29 PSI.
33F/29R is the recommended tire pressure for a car without any passengers or cargo. For a car carrying the maximum weight permitted, the recommended tire pressure is 44F/44R. If unsure, 35 square is a solid choice. I drive a 2019 GLA250 4MATIC with winter tires during this season.
What is the recommended air pressure for the tires on a 2015 Mercedes CLA 250 with 20-inch wheels?
