OK people, can you help or set my mind at rest.

I'm on my second set of tyres on my Mkiv R32, they are goodyear F1s I've done about 15k on them and have noticed that the rears are almost worn to nothing on their inside edges.

What brought this about is that I thought my drivetrain was excessively noisy so I checked the tyres. Would the tyre wear make the drivetrain sound noisy?

Also the fronts and the outside edges of the rears have about 3 mm left on them. What could have caused the rears to wear like this?

I don't think I drive excessively hard, I like to push round the occasional corner and like to accelerate as fast as poss sometimes but not all the time.

I didn't have this problem with the original Michelins but I did have one faulty one on the rear that ended up looking like a 50 pence piece on its inside edge. They lasted 18.8k

All help greatly appreciated.

mine is very simular .......but i have wear on the outer edge

next time i buy tyres which is very soon

im getting a geo metric done to check the camber ...think it might be out a little bit

but then about 15k on tyres that have been pushed a little sounds about right to get that milage from them

not sure gerard, I'm pretty sure that is has a different camber setting to the GTi or V6 4Mo

But it is set the way it was from the factory, surely it shouldn't go out by much over a year or so

Yeah but the fronts and the outside of the rears still have about 3 mm

yer my front have equal wear across but the back are worn to next to nothing and the inner half of the tyres has a few mm left

im pretty sure the camber needs adjusting .........it might be worth getting it checked .....

Yes, especially if the "blocks" on the edge have worn odd unequally to each other; the one next door has more tread...

...sounds impossible to happen but it does and creates odd noised that are confused with all maner of other problems.

with the roads we have up here i'd get the alignment checked out, i'm not to clued up about camber on the R32, i'ii check some books at work and see what they say, to see if the camber can be adjusted or not.

The 4motion (which the R is based on) has negative rear camber at the
best of times (means the top of the wheels is further in than the
bottom) the R is lowered further still which accentuates
the negative camber, neil S bought Tabs's old R suspension and when he
setup the geometry that the negative camber was -3 degrees (this
is alot for a standard car)

The TT, R32 and 4motion all have a problem with wearing the inside edge
of rear tyres when lowered (see this website
http://www.wak-tt.com/mods/reararms/reararms.htm ) it just so happens
that the R32 is the lowest of all three of the above cars so has been
known to suffer this problem as standard or when carrying alot of
weight around as normal.

PS the R32 should have slightly more modern tie bars than TT's and
4motions that will allow for 1.5 dgree of camber adjustment (they have
an oval bolt hole on one end)

however it is next to useless and cannot be adjusted by even the best
tech, the best and only reasonabley accurate way is to invest in som
forge motorsport tie bars.

I think its quite normal to be honest.

I've covered almost 18k on my set of F1's, and today I had one of the rears off for a puncture repair.

The tyre has maybe only 5mm of tread left in total, but the inside of
the tyre is very much more worn than the outside blocks (talking about
the rear tyres only). Which means that the tyres are wearing out
due to the negative camber on the rear. U can see the
negative camber on the rear wheels if u follow the R32 from behind,
driving along. The rears are much more sprayed out than the
fronts..

The same wear pattern happened on my friends R32 with his tyres, and
EVEN MORE SO when he had 19x8.5J wheels. The bigger tyres he had
wore out even quicker on the inner edge than on standard 18's!

Oh, and yes same wear pattern happened on the original Pilot sports too.

Try swapping tyres back to front to even out the wear rate across the tyres.

It is right to say that the rear tie-bars are responsible for the
negative camber, late R32's did have 'slots' to allow for a small
amount of camber adjustment, which is in itself imho the cause of this
type of tyre wear.

Here's the ETKA & ElsaWin shots about it.......

My 4mo rears are worn on the inside edges a lot more than the outers
and the camber can be seen quite clearly to be out by a small amount,
and thats just lowered 35mm.

I think the only way to cure this problem is to replace the tie-bars
for a set that allow mucho adjustment, at the moment the only option is
the forge motorsport tt ones, which look very very good quality
when I checked a set out,(but then @ ?250+vat they should be!).
Then a 4 wheel alignment would be in order to get the camber set
correctly.

Maybe I'll test the water early next year for a GB on these bars from Forge?

There does seem to be a lot more 4mo's on here now so along with the R32's this may prove worthwhile.

sounds like we will have to suffer the tyre wear then ,

and i have fitted eibach springs so it will be slightly lower .............and causeing more wear

19 x 9 ich wheels so even more wear to the edge ..........

and the H&R Anti roll bars ,

is there no way that we can stop this wear of the tyres to minimum....................

Someone approached forge about a group buy a while ago, and the best
they could do was waive the VAT so it was 250 all in i think

A while ago evilhomer myself and I think (Raj20vt) did an exercise in
having the original tie bar holes welded closed and then re-drilled,
only raj was successfull, mainly because evil sold his car and I
had forge type ones made out of mine by a local engineering firm, but i
wasnt happy with the quality. (Forge supplie these Items on an exchange
basis anyway) Raj used a cad drawing to calculate the exact redrilling
measurments.

We all bought packs of 4 new tie bars bolts and bushes for ?10 of some
bloke on ebeay, if someone wants 2 to mess with I think evilhomer may
still have his

PS Milltek are another supplier of these but are even more steep tha
forge, also the yanks sometimes use an eccentric bolt and bush set but
thsi is not too easy to adjust and is only ?50 cheaper than the real
tie bars
