I bought snow tires for my 2009 Fit from Tire Rack and just had them mounted on some basic steel 15" wheels. Can anyone tell me if I need to reprogram or change anything so the car's computer adjusts for the different tire size? I went from the stock, OEM wheels to 175/65R15 on the snow tires.

Sorry if this has come up before - I couldn't find any answers.

Thanks!

 

depending on the outerdiameter of the tyres, your speedo may be slow or fast depending if the new tyres are taller or shorter than the stockers. other than the tpms light being on, you shouldnt have any issues

 

The closest match to stock dia is 195/40/17's
