Increased fuel consumption after changing tires?

Hello everyone, I have an Opel Astra and have noticed an increase in fuel consumption of about 0.5 liters since the last tire change. In addition, my vehicle has been displaying the error code P200A for 2-3 weeks. Could the tire change be related to the increased fuel consumption, or is the error code possibly the cause? Has anyone had similar experiences or any tips on how I can solve the problem? Many thanks in advance!

Summary of the thread

The issue of increased fuel consumption in an Opel Astra arose after a tire change, with a concurrent error code P200A. The tire change involved switching to new all-season tires, but the size remained the same, suggesting the tires are unlikely the cause. The error code P200A, related to intake manifold runner performance, is identified as a potential cause. It is recommended to inspect the intake manifold runner control valve for any malfunctions, as this could impact engine performance and fuel efficiency.

Check if the new tires have a different size or type compared to the old ones, as this can affect fuel consumption. For the error code P200A, it relates to the intake manifold runner performance. Inspect the intake manifold and its components for any blockages or issues. Let me know how it goes or if you have further questions!

Tires were changed from summer to new all-season tires. Nothing has changed in terms of size.

Since the tire size hasn't changed, the increased fuel consumption might be more related to the error code P200A. Check the intake manifold runner control valve for any signs of sticking or malfunction. This can affect engine performance and fuel efficiency. If you're unsure, it's best to have a mechanic inspect it, as it can impact engine performance. Let me know if you need more help!
