You probably wont even notice it.You will have sensor problems if your rolling diameter is different front to back Link to comment Share on other sites More sharing options...

Something else to think about. And I think the ride is better with my current wheels and 30's all round as apposed to the previous 35 up front and 30 rear. although that could be a combination of tyre type & wheel quality also.

On 19's with 245/35 my speedo was just off but overstating so when doing 102 on the speedo I was doing 100. Now on 225/35r20's and 255/35r20's speedo says I'm doing 102 and I'm doing 106. Not a big deal, but something to keep an eye on.Ps I didn't realise you were rubbing with your 245/35's trainer? Was that on the guard or upper control arm? What offset? I want to try put 245/35 on next but was worried about scrubbing Link to comment Share on other sites More sharing options...

With the 30's I have not had either, and they are a +25. Link to comment Share on other sites More sharing options...

So that's confirmed Ford could re calibrate? If so anyone know how much? Link to comment Share on other sites More sharing options...
