October 25, 201510 yr Looking to put my old wheels on for winter with some winter tyres. My car is MY99 classic that is running 215 40 17 on OZ's but I think the original OEM 16" wheels run 205 50 16 but looks like a some good offers on 205 55 16 and wanted to check if these would be suitable. Thanks
October 25, 201510 yr If you can get the total wheel/tyre diameter and circumference the same as what it currently is then the Speedo will remain the same. From what I can remember there are a couple of websites that offer a calculation to sort it without too much brain ache. The difference between 205/50 and 205/55 is 10.25mm. If the speedo reads 30mph the 205/55 would be going 31.01mph and at 70mph you'd be doing 72.34mph. Not enough to get in trouble but certainly something to consider. Hope this helps [emoji4]
October 25, 201510 yr One main thing to consider is I take it you have the 4pots on as standard and are the oem 16" the ones that clear the calipers or a set you've picked up ? If the latter you may have clearence issues
October 25, 201510 yr Author The 16" wheels and 4pot brakes are all the originals so no problem with clearance. Speedo changes sound fine as will only be on the car for a few weeks when snow or really cold. Soon as the weather allows the OZ's will be back on. Thanks Sent from my iPhone using Tapatalk
