the alinment?

unless you wasz running on train tracks, theres no way you would get a groove as bad as that. it would be evenly worn across the tyre.

i know with the alinment out your tyres wear,but not like that. even if the cambers were out it would not be as bad as that.

id still say to check the off set, and then check your suspension legs.
try jacking one of the sides up at the hub mate, you may find something

Ive seen lots of tyres do this through alignment. Usually through being lowered too much combined with alot of toe out.

Go ask your local tyre shop if you dont belive me.

Surely some kind of rubbing issue?!?! Looks like a spacer has been taken out, and someone forgot to put it back...

Have you had the car long? It would be pretty hard to not notice such extreme rubbing.... maybe the previous owner.....

Alignment being out would not mean the tyre would be evenly worn accross the tyre, in fact completely the opposite. As frayz said a combination of toe out and wrong camber would scrub the inner edge off - it did on my previous car, a Slammed valver. This is an extreme case though and due to the step I would suggest it has been rubbing on something aswell. It hasnt gone like that overnight though, you will be checking them more regularly in future I rekon?

catons scooby

when did you get the prodrive geometry done, and do you have fat mates, no offence intended....

catons scooby

o and by the way, the other plus side your car will probably feel quicker now as no friction with this wheel....

I'm with frayz, with this kind of wear we usually find something on the suspension has failed or bent (?)...

serious tracking problem by the looks of it . or its rubbing on something . check for marks on the suspension struts or arches

Schumacher

Got back after having the geometry checked - everything appears okay? I'll post the printout a little later. Now I'm a little confused... Maybe it's just a bad batch of tyres?


The tyre is NOT from the car in my profile - that's parked up with a busted engine. The tyre failed on my other Impreza. And yes, everyone has fat mates!

with messing about with cambers and toe in & out. the toe in would have had to be over 40' out. and theres no way that can happen on a scoob the way there set up

so if the off set is ok, then if the tyres were on there while the damage was done. it has to be something wrong with the legs.something out of place

wsell, again. hope you sort this issue you have mate

RB5_203

Frayz is right!

I have had the same problem in the last couple of months with both my RB5's, still have the tyres so took some pictures to prove this! a combination of taking corners fast with a wrong setup made mine go exactly the same as in the above pictures!

and mine happened with Toyo T1 R and the S's on the road!

Tyre from RB5 101




My hallway is currently filled with tyres!

Eagle F1's, R888's and the Hankook RS2's that I used at rallyday and was supprised at how well they did for a £95 track tyre!

but if you look at them tyres, there worn across the hole tyre.
they worn more on the inside so i would have said the camber was wrong.

i had tyres like that in the past.
vecrtas are a bleeder for that

bibo_boy

Hate to say it but I'm with Frayz too.... exactly the same happened to me when I was a kid... Escort lowered to the deck with angle grinder and never checking tire pressures = no inner side walls!!!!

Schumacher

RB5_203, was yours due to toe-out? Did you get a printout of the settings??




(Busted tyre was put back on the left rear)

Edit: Forgot to add... Had to jack up the left rear to take off the space saver and put the old tyre back on just before the check. Asked the guys if this would affect the results, was told no?

Funny how Fifth Gear are talking about tyres?!

jeansmechanic

If it was rubbing on anything then surely you would smell it and see the blue smoke pouring from the wheel arches going along, also it would make a hurrendous noise. I also fit tyres for a living and it is so common, incorrect pressures, toe out, camber angles. If the car is lowered the camber changes and can cause that problem with out the tracking being out. It would only have to be about 7mm toe out to cause that much damage.
Defo not rubbing on anything in my opinion.
Where are you from mate?

I lost a full set of tyres on my old bugeye sport in 6k, this was before I knew anything about this problem. I swaped front to back when I noticed something was wrong at around 4k then researched the subject..... what an eye opener that was ! I simply ran for another 2k until the handling was so bad I changed all 4 and had the alighnment done by Powerstation, that set went on for ages and I even sold them on they were spot on.

On a positive Schuey it's just as well you found them when you did, you could have been going at 70 old pal and you don't want to even think about that.

fair comment, that didn't quite come across properly in a hasty written post
what i was trying to get at was if you treat nangkangs like a high performance tyre you'll come unstuck, saw a mates nankang virtually totally delaminated after some spirited driving. blocks pulled off, canvas showing, scary stuff!

anyways back on topic, good luck getting sorted schumacher. bloody lucky you spotted that

G00ner

That's interesting...

When I brought my GSi Estate new it was chewing up tyres in exactly the same way on the back of the car, I went through over 20 tyres in 100k miles.
Retards at Vauxhall never did work out why it was doing it...

I don't think you would hear it if they are rubbing, I never did in my GSi.

Get a 2nd opinion on the tracking, most of these tyre places are managed by numpties with no technical ability, badly calibrated equipment and no idea on how to use it anyway.

skoobidude

Had exactly the same happen on my car a few weeks back.
Although I'd driven to work that day with the car pulling to one side slightly. Then on inspection spotted the front nearside to be rather low on air so I took it to nearby garage to pump up but the air wouldn't go in...
Convinced the valve was knackered I took it a little further to a tyre place only to spot exactly the same as the original posted piccys when I parked (with wheels turned)
Tracking mate!

Ignore half the suggestions above. My wheels and tyres were standard on the car from new. I'd caught the kerb on reversing into my garage (which sits parallel to the road) on a few occasions.. This led to the slight pulling to one side but conveniently the tyres were on the way out anyway so I ignored the pulling thinking I'd get it done at the same time as fitting new tyres. But in the end I had to part with my cash a little early
I would suggest you have either knocked/scraped a kerb at some point or your tracking was out to start with.

Mikkel

I'm not sure which I most shocked at, the state of that tyre or the fact you actually take your wheels off to wash them Still, just as well you do!

Schumacher

Yeah, if it was rubbing I'd see smoke and smell it. I'd also see marks on the strut etc whenever I clean the wheels, but there's nothing there. Definitely not rubbing.

Any more opinions on the geometry printout (post #44)? Need all the advice I can get but also ASAP so I can decide on what to do next. Everyone I've shown the tyre to have been baffled by it. Can't really drive the car so I'm stuck up north not being able to get to work.

To whoever asked, I'm currently in Doncaster.

jeansmechanic

Is the car on standard suspension Schumacher?

Schumacher

Dropped on H&R springs with stock struts.




Mine's the white one.

From the printout your camber and toe look fine.

1 degree on the front is much less than i run. Also your toe is so shallow that it too isnt going to cause an issue.

Your front castor differs by a whole degree between left and right. I wonder if your lower pickup has moved on it mounting as this should be equal both sides. especially as youre still on stock topmounts. This will alter your dynamic camber when the wheels are turned but not enough to cause your issue IMO.

Its not related to your issue but your rear camber differs by almost 2 degrees, id add some camber bolts to the rear and get that dialed in equally.

Id be inclined to show that printout to a chassis specialist such as Zak at Mocom and see if he can shed some light on your issue.

Sorry i cant help more.

jeansmechanic

Sweet ride. Who changed the springs? Did they do the tracking and camber adjustment on it after fitment do you know? The front struts have camber adjustment bolts fitted

Schumacher

Springs were done by previous owner.

Frayz, -2 degrees on the left rear was the busted tyre. We jacked up the car to remove the space saver to put the busted one back on for the alignment check. Car wasn't driven so the suspension wasn't settled. -2 definitely relates to the tyre wear.

The front offside (right) tyre is shaping the same. I'll get some pics later today.

Can't really take it to Zak as I'm stuck up north.

frayz

iTrader: (7)

Fair play mate, is there not a chassis specialist in the area?

May even be worth a call to Zak to discuss the alignment settings. He may see/suggest something that I may not.

Im an engine builder remember lol

Schumacher

I don't know Doncaster that well. I'm a Londoner, ha.

Yeah, might be worth giving Zak a call later in morning.

nixxon

You wouldn't necessarily see smoke etc. Depends how harshly it was rubbing.
If it's alignment causing this, you would also possibly smell it, and the car would drive like an absolute pig.
Was there any sign of rubbing last time you took the wheels off? How long ago was that? Did you swap them front- rear? Are the rears starting to look the same?
What tyre pressures are you running? The combination of low pressure and cheap tyres could result in the the rim causing the groove. What section are the tyres?
And finally, don't assume the -2 camber is caused by the car not being settled. If it had just been jacked up, and not settled, it would probably read positive, not negative. I know mine would!
Get the alignment done again, somewhere else, and settl the car by rolling it a couple of yards. A difference of 2deg in rear camber is plenty enough to make the car crab slightly, or make it pull to one side.
