rickya Posted August 30, 2006 Share Posted August 30, 2006 This is a post earlier this year by CDR. Just wondering others thoughts on this, as I missed this discussion earlier. "I kept the original size on the rear (245/45-18) and went for a wider tyre on the front: 245/40-18 The result is that the car is much less prone to understeer in the dry, and the feeling is much more neutral between front and rear. I based my decision to go for the same width front and rear on the fact that this is what many japanese tuners are doing with the Z (Amuse, Mines, Boss, Sunline Auto etc.). Before anybody says different - 245/40-18 from BF Goodrich (which is in fact Michelin) is the same diameter as the original 225/45-18's on an 8" wide rim. This means the stagger between front and rear is unchanged, and their are no problems with ESP. I've tried this setup out on a few tracks and it's very good My friend has also tried the Falkens on track, and complains all the time about the soft sidewalls."

lomoto Posted August 30, 2006 Share Posted August 30, 2006 Doesnt do any harm to experiment , sounds about right regarding the understeer will just work out expensive if you get it wrong in more ways than one..... I think for normal road use I will stick to the conventional wisdom on sizes.. Nissan didnt spend lots of time developing correct sizes for nothing... ( mind you saying that they did stick bloody Bridgestones on ) Quote Link to comment Share on other sites More sharing options...
buds Posted August 30, 2006 Share Posted August 30, 2006 They cant be that bad? Car im looking at has them on, and i cant afford to put 4 new tyres on when they all have good threads! Well i could, but would have to postpone exhaust. Quote Link to comment Share on other sites More sharing options...

They can ,, especially in cold / wet conditions..probably ideal for Spain though in mid summer Quote Link to comment Share on other sites More sharing options...

Guest prescience Posted August 30, 2006 Share Posted August 30, 2006 245x35 on 19 stays closest to the stock ratio and is recommended, despite what your man says Quote Link to comment Share on other sites More sharing options...
