liam42whu Posted February 17, 2011 Share Posted February 17, 2011 Hey all, The story is, I got a puncture so I fitted the spare wheel, since then I replace both rears as the non punctured one was worn quite bad, and now wen turning right the traction control comes on for no reason. Is the wheel speed sencor easily damage When using the spare? Can a damaged wheel speed sencor affect the traction control? Any other ideas. Thanks liam.

introspect Posted February 17, 2011 Share Posted February 17, 2011 Are all four tyres the same brand? Have you checked tyre pressures are all correct (should be 35psi)? Quote Link to comment Share on other sites More sharing options...
Neilp Posted February 17, 2011 Share Posted February 17, 2011 What size are the Tyres you fitted? Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted February 17, 2011 Share Posted February 17, 2011 tyre size? pressure? brand fitted? if they are directional tyres are they facing the right way, if all 4 were taken off have you checked they haven't put the fronts on the back and vice versa?

liam42whu Posted February 17, 2011 Author Share Posted February 17, 2011 Size- 245 45 18 Make- avon z33 Pressure -were a bit high but only 2 psi Thing it's the side that got the puncture that's playin up Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted February 17, 2011 Share Posted February 17, 2011 does it only happen when you turn in that direction or does it not matter happens when you turn left or right? Quote Link to comment Share on other sites More sharing options...

liam42whu Posted February 17, 2011 Author Share Posted February 17, 2011 Due to lack of funds brigestones, although they will be replaced in a couple of weeks, Quote Link to comment Share on other sites More sharing options...
liam42whu Posted February 17, 2011 Author Share Posted February 17, 2011 Ooo and it did in a straight line so I turned it off, but I dont like driving with it off so that's not a option Quote Link to comment Share on other sites More sharing options...
introspect Posted February 17, 2011 Share Posted February 17, 2011 Due to lack of funds brigestones, although they will be replaced in a couple of weeks, I suspect that's the source of your problem then. Mixing tyres on the zed is a big no no. Quote Link to comment Share on other sites More sharing options...
liam42whu Posted February 17, 2011 Author Share Posted February 17, 2011 I know it a big no no, but it's only when turning one way, and plenty of other run like this so it shouldn't do this. Quote Link to comment Share on other sites More sharing options...
Ekona Posted February 17, 2011 Share Posted February 17, 2011 Yes it should. You've created an imbalance between the two ends of the car and the TCS has no idea what's going on, hence you're getting odd symptoms. In the meantime, just be more gentle on the throttle as that'll be a big reason why everything's getting confuzzled so quickly. Quote Link to comment Share on other sites More sharing options...

CrumbMC Posted February 17, 2011 Share Posted February 17, 2011 When i bought my Z it had different brands front and back and the TCS was grabbing at my wheels all the time. now with all 4 Decent same brand tyres the problem has gone. but the starting routine of my Z is clutch in, turn key, Turn off traction control, so i don't have this problem. Hope u get it sorted mate Quote Link to comment Share on other sites More sharing options...
Matt L Posted February 17, 2011 Share Posted February 17, 2011 mine has different tyres on the front and back and i have never had this problem, i know that doesnt really help you find ou what it is but just so you know im not experiencing the same problems with different tyres on the front and back.

Same here, I bought some alloys off another member and they are different brands front and back. This is going to be rectified next month but I have never had any TC issues with the different brands. Again probably not very helpful to your issue. Quote Link to comment Share on other sites More sharing options...
Ekona Posted February 17, 2011 Share Posted February 17, 2011 If you're smooth with your inputs you won't notice much difference with mixed tyres until you need them in an emergency. Quote Link to comment Share on other sites More sharing options...

docwra Posted February 17, 2011 Share Posted February 17, 2011 I have now run 3 different sets of wheels and 12 different sets of rear tyres on my car and not once have had the traction control problem you are talking about. I really, really dont think its mismatched tyres, but Im sure Ill be told different. Think about it - there TC kicks in when there are differing wheels speeds from front to back. I know you guys REALLY hate mismatched tyres but are you seriously telling me that it would cause the rears to rotate faster/slower than the fronts?? And dont tell me its due to wheelspin, no tyre is that bad that you are incapable of pulling off without spinning it up. My guess is that the rolling radius ratio has been changed, same as if you were running 19's on the back and 18';s on the front (which Im aboput to try myself actually) - different tyres makes in the same sizes will have sidewall variations that could cause this.

liam42whu Posted February 17, 2011 Author Share Posted February 17, 2011 Different tyres would never give me that problem, wheel speed sencor being damage mite, so I'm goin to go with that for now, cheers guys Quote Link to comment Share on other sites More sharing options...
Neilp Posted February 17, 2011 Share Posted February 17, 2011 i have run mixed tyres on the track as my track wheels had a puncture, and even pushing hard and i never had traction control light up Quote Link to comment Share on other sites More sharing options...
Ekona Posted February 17, 2011 Share Posted February 17, 2011 So basically you're going to ignore all (well, the vast majority) of the advice here and go with your gut? Well, I'm really glad we all bothered taking time to give you the benefit of our experience. You've got vastly different compounds on the rear to the front, and as such totally different grip levels, and you're wondering why the car is doing weird things? I genuinely hope it is just a wheel speed sensor, but even if it is you've still got a mis-balanced car once it's replaced. Quote Link to comment Share on other sites More sharing options...

As with my car i had mixed tyres but were both premium brand and relatively soft compound Quote Link to comment Share on other sites More sharing options...

As with my car i had mixed tyres but were both premium brand and relatively soft compound +1 someone usually has £10 tyres on the back and and crappy ones on the front which happen to be mismatched and then people upgrade to a proper tyre and say its because they where matched, mainly cos they where crap. Docwra let me know how that goes as I have wanted to do that. Quote Link to comment Share on other sites More sharing options...

Docwra let me know how that goes as I have wanted to do that. Blimey, someone who can see what Im saying I cant get over some of the hysterics that surround mismatched tyres on here, I mean again, how is two different compounds fore and aft going to affect wheel speed? Hes talking about turning, not under hard acceleration or when driving on ice ......... So basically you're going to ignore all (well, the vast majority) of the advice here and go with your gut? Well, I'm really glad we all bothered taking time to give you the benefit of our experience. Id add he isnt ignoring the experience of others, it seems to me that there are a lot of people who have run mismatched tyres and not had this problem, 5 on this thread in fact, and only one who did have the issue with mismatched tyres. Id say he is going with the majority. Oh, and as regards 18s front and 19's rear I dont for one second think my TC will work in that configuration, but its got to be tried Quote Link to comment Share on other sites More sharing options...
