unusual tyre wear


Recommended Posts

Guest skylinegirl

hi guys,

i have a problem with my R33, the right rear tyre is wearing on the inside,im only getting 10,000k,s out of it maximum.All my tyres wear on the inside but i can get 20,000k,s out of the rest of them which im told is normal for performance tyres.Ive had new shocks installed in the rear as the right one was stuffed,i thought that may have been the reason for the unusual wear but it wasnt.I had a wheel alignment done after the shocks were installed and the last set of new tyres and i still got wear on the right rear, ive taken it back to wheel alignment guys and they dont think its anything to do with the wheel alignment.Can anyone help me as to what may be the problem????

............Thanks

Toe angle can be a major culprit here. Negative camber will affect tyre wear slightly, but not nearly as much as bad toe. I wore mine down to the steel belts before I noticed! I was keeping an eye on the outside edges of my tyres which was still almost brand new, then when I took my car in for tuning, my mechanic said "you know about your tyres being worn down to the belts don't you?" "NO!?" Had a look when it was on the hoist, fark!!!!! The front tyres had gone from new to dangerous in about 8000km.

It could also be worn suspension bushes (causing your toe to fluctuate). How are they doing your wheel alignment? With lasers or strings? And are they doing a 4 wheel alignment or just front?

I have a print out of the wheel alignment.So hopefully its on that.(camber,castor and toe) I'll have a look for it let you know....thanks mick

Yeah same here jimx......Done with lasers and yes it was a 4 wheel alignment.......What have you done to yours to fix the problem???

If there was something wrong with your suspension, surely they would have picked it up while doing to '4 wheel' alignment. Take it elsewhere & get a second opinion. Last time I got mine done was at Pedders - 4 Wheel Alignment cost ~$100.00, they checked my car out before doing the alignment, plus they had white papers on what the correct figures should be (camber, castor, toe) all the skylines (32,33,34). Good luck with it.

Cheers,

C.

Yes it certainly should be there. Let me know what they are and I can tell you if that is the problem. Even if u do have a problem with the suspension it should show up on the alignment.

If you cant figure it out let me know and I will get a fax number you can send it to so that I can have a look and see what it says.

Goodyear at Castle Hill do a fantastic 4 wheel alignment with lasers, and it only costs $60. They are familiar with Skylines too, they can get it up on the ramps even if you have a really low front bar (like I do :rofl:) It's a major hike even for me but they're open Saturdays and worth the effort.

Hmm there is certainly nothing hugely wrong there. 1degree neg camber is not a big concern thats for sure and 2mm toe is nothing massive either. All looks good there. You may need to get it done again just to make sure that it is right but looking at that all looks good. A rear camber kit may help marginally butif those readings are correct then really it is not going to improve things much. Other than suggesting getting another alignment done just to be sure I don't have much to offer. Sorry.

Mick.

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
