pathfinder123 Posted November 27, 2009 Share Posted November 27, 2009 Got a bit of a weird problem, which I hope someone can throw light on. For about 1/2 mile or so from cold my 350z steering feels very light, almost like driving on a slippery road. After that I get the normal steering response with the right amount of feedback,and all is well. I am sure it's not a tyre heating issue, as I get the same symptoms whether I drive at 70 or 7 MPH. The fronts are Bridgestones, and have a reasonable tread left. Could it be the PAS, or something associated with it ? Cheers S. Quote Link to comment Share on other sites More sharing options...
Trev-the-Rev Posted November 27, 2009 Share Posted November 27, 2009 Maybe an obvious question but have you checked the pressures? Should be 35 psi. Quote Link to comment Share on other sites More sharing options...
pathfinder123 Posted November 27, 2009 Author Share Posted November 27, 2009 I haven't, but why would the steering suddenly change ? S. Quote Link to comment Share on other sites More sharing options...

pathfinder123 Posted November 27, 2009 Author Share Posted November 27, 2009 Brand new Falkens. S. Quote Link to comment Share on other sites More sharing options...
Ekona Posted November 27, 2009 Share Posted November 27, 2009 Yup, that'll do it. Difference in tyre compound front and rear (especially in these changeable conditions) will lead to the temps not being equal and give you dodgy handling. Change the fronts for Falkens ASAP before something nasty happens. Quote Link to comment Share on other sites More sharing options...
Chris`I Posted November 27, 2009 Share Posted November 27, 2009 Yeah we have seen this a few times going between different compounds. Some say its fine, but more say its dodgy. Havent done it myself, but if its not handling right then that would be my first port of call. Quote Link to comment Share on other sites More sharing options...
Lincolnbaggie Posted November 27, 2009 Share Posted November 27, 2009 I have noticed a similar feeling as well (running Falkens on all four corners) - it always takes a 1/2 mile or so for me to feel confident about the grip from cold (and I've checked pressures/tread etc). Also feels like the road is slippery for that first couple of minutes. I've just got used to it and wait for some heat to get into the tyres. I assumed it was normal Quote Link to comment Share on other sites More sharing options...

I assumed it was normal Cant say I get the same feeling with mine running Falkens, but then I take it easy for the first 5-10mins while the oil gets up to temp. Maybe get your tracking/allignment checked, my car felt 10x better once I had mine done Quote Link to comment Share on other sites More sharing options...

Maybe get your tracking/allignment checked, my car felt 10x better once I had mine done That's why it's never bothered me too much as I always take it easy as well to get everything up to temp. I'll probably get the tracking checked to be on the safe side. Quote Link to comment Share on other sites More sharing options...

Sounds like you are experiencing the same effect as me. I have planned on replacing the fronts with Falkens after Christmas, and will get the tracking checked at the same time. As I said there is a fair amount of tread left on my Stones, so they should still be working. I find it difficult to believe that it is caused by the tyre temperature changing over 1/2 mile of sedate driving. I have never noticed this effect with any of the many cars that I have driven, why should the Zed be different ? Anyone with a tyre temperature gauge that they can loan me for an investigation ? S.
