Tocchi Sandtrap Motorsport Donating Members 2,055 Member For: 16y 1m 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............. Link to comment Share on other sites More sharing options...

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 Share on other sites More sharing options...
