Subaru Forester tire size, battery and oil
What fits a Subaru Forester, generation by generation: the factory tire sizes by trim, the battery group, the engine oil and the wiper blade lengths. Each line is checked against two independent sources. Before you buy, read the sticker inside the driver's door: it lists the size your Forester left the factory with.
