Tocchi Sandtrap Motorsport Donating Members 2,055 Member For: 16y 4m 29d Gender: Male Location: Perth Posted 05/07/10 06:23 AM Share Posted 05/07/10 06:23 AM got a pair of 235/40/R17 tyres, and im looking at a pair of 235/45putting the 45's on the front, and the 40's on the rear ... helping to set the car up for less understeer and a tad more oversteer.is the speedo worked out on gearbox output or something?basically, I know my speedo may be out (pending on where its measured from)... not as issue, as a hardcore street racer im immune to speed cameras.just want to know if it will throw up any error codes due to the staggered sidewall profiles?

Your looking at aprox 12% difference in rolling Diameter. You may get away with this.Only one way to find out.............

No abnormal operation though, didn't phase me, but that might have changed if I need to jump on the anchors on the highway Link to comment https://www.fordxr6turbo.com/forum/topic/69202-sidewall-profiles-staggering/#findComment-1021955 Share on other sites More sharing options...
