I'm looking for wheels and tires 16 inches diameter for a GR86 due to necessity of all-season tires. Tire Rack.com just shows 17 inches options, but I need 16 inches.
If you search for wheels on Tire Rack, you can select diameters in the left column. For some reason, selecting only 16” doesn’t eliminate all the non-16” options, but if you sort by price (low to high), you’ll see plenty of 16” options.
You can also shop around by wheel specs. Look for 5x100 bolt pattern and something that can accommodate 56.1 mm center bore with or without spacers. Stock offset is 48 mm if you want to stay close.
If you’re looking for winter beater wheels, you can find donors from plenty of other Subaru models that use the same bolt pattern, hub, and offset. Lots of Foresters, Imprezas, Crosstreks, older Legacies… Some of them may have bigger OEM
tires but compatible wheels. There are plenty of web sites you can use to cross-reference by year/model like wheel-size.com .
You don’t need to go to a 16” wheel for all-season tires, though. There are plenty of all-season tire options that fit our stock 17” and 18” wheels.
