54Arosa Posted September 16, 2014 Report Share Posted September 16, 2014 Buying some 13x7 banded steel wheels, and will be wrapping them in 175/50 Yokohama's, will this knock out my speedo? (It is currently fitted with standard 14x6 185/55)Thanks for any help Quote Link to comment Share on other sites More sharing options...

bobbo Posted September 17, 2014 Report Share Posted September 17, 2014 (edited) Bit more than barely, almost 11% speedo error! www.willtheyfit.comVery handy site, will tell you everything you need to know Edited September 17, 2014 by bobbo Quote Link to comment Share on other sites More sharing options...
Vwlup0 Posted September 18, 2014 Report Share Posted September 18, 2014 Give or take as to how much the speedo is already out as standard, you'll probably be about 4-5 mph out at 70, so I wouldn't worry to be fair.. Quote Link to comment Share on other sites More sharing options...
bobbo Posted September 18, 2014 Report Share Posted September 18, 2014 Well, what is currently indicated at 70mph will be indicated at 11% above that with the 13's, so what used to show as 70mph will show as 77.7mph. Not insignificant IMO. Quote Link to comment Share on other sites More sharing options...
54Arosa Posted September 19, 2014 Author Report Share Posted September 19, 2014 I'll just keep a satnav in my car, that shows my actual speed Quote Link to comment Share on other sites More sharing options...
