Umster Posted August 1, 2019 Share Posted August 1, 2019 How much of an impact does having larger alloys and larger profile tyres have on an odometer? Can it be corrected? Is it legal? Is it worth it? Quote Link to comment Share on other sites More sharing options...
pintopete58 Posted August 1, 2019 Share Posted August 1, 2019 If you go bigger on your tyer wall you need smaller wheels . if you go smaller side wall you go bigger wheels. If you just go bigger every thing your speedo will out and you get readings on your dash Quote Link to comment Share on other sites More sharing options...

Umster Posted August 1, 2019 Author Share Posted August 1, 2019 Well I'm more concerned about the odometer and if the mileage I've actually covered is the same as the mileage shown on the clock. Friend has told me I should get the counting mechanism recalibrated as my aftermarket alloys will cause a speedo and mileage error. Quote Link to comment Share on other sites More sharing options...
Silverthorn Posted August 1, 2019 Share Posted August 1, 2019 Error is very minimal to the point i wouldn't even worry. Pop the stock wheel specs and the wheel specs that you are considering into willtheyfit.com and it'll tell you difference in a percentage and mph at 30 & 60. 1 Quote Link to comment Share on other sites More sharing options...
