bluegp Posted June 22, 2004 Report Share Posted June 22, 2004 225/55/16 - is anyone running these tires...will this make my speedo be innacurate? That's the size I have. I like them because they look a lot wider than the 60 series. In my case, the '89 originally came with 195/70/15 tires (that size is not made anymore) and the 225/55/16 comes out to be the same diameter. There were a few different size tires used on the W's - I doubt there were any differences in the VSS, ECM, etc. between these cars. There's probably a "average" tire diameter that the parts are calibrated for. Like said, your speedo may be a little off anyway. If it is dead on right now, it will be a little off when those tires are used. Here's a speedometer error calculator: http://www.paspeedo.com/calculator.htm With the sizes mentioned, it says that when the speedo would read 55 MPH, the actual speed would be 53 MPH.

BIGBULS Posted June 22, 2004 Report Share Posted June 22, 2004 It's ~3% difference............not that bad. I'd do it if you are a little strapped for cash. Quote Link to comment Share on other sites More sharing options...

Baddflash Posted June 23, 2004 Report Share Posted June 23, 2004 For sure get the tires, good deal! My car originally came with 195/75/14 but now has 225/60/16 buy those calculations it would read under by a few mph. LOL! I forgot I'm using the chip and ss from another car so I have no idea how far my speedo is off. Any idea what a '90 GP SE with 5-spd might have gotten for factory tires/rim size???

joey b Posted June 24, 2004 Report Share Posted June 24, 2004 I can get 3 like new yokos for 45 bucks, maybe 50 series though. What do you think about that and is there anyway to correct the speedo? Quote Link to comment Share on other sites More sharing options...
