Correct Stock TIre Size

Hi guys,
My bird has 15" wheels on now but I think it came with 16" (it's a formula). What would be the correct size so the speedo is accurate? I've got 215/65/15's on it now.

Tire sizes should be listed on a placard on the door.

What if the placard is faded, or painted over(Like mine)?

What is the stock tire size?

Re: Correct Stock TIre Size

depends. one option was 235/60 15 - and there was 215/65 15
both are 26 inches high which is what your speedo is set for from the factory.

even the 16 inch rims will only be 26 inch diameter. so it could have been 255/50 16, or 235/55 16.
there may have been a 255/60 16 too.
they are all about 26 in diameter, give or take a little.
