rear end issue a wheel issue

[pitslayer]

as some of you may of read ive had a thud which sounds like a buggered CV joint coming from the back. yesterday i changed over to the facelift alloys, and the noise is mostly gone. still can be feintly heard, but its alot duller, in tone.
time to get the wheels balanced i think. all tyre pressures are at 36psi
strange.

I run 32 at the front and 34 at the rear. Reading through in the past I would have thought 36 all round was a little harsh. Must admit though my fronts have always looked under inflated on any tyres on both the cars.

are those figurers on a 16'' or 17'' wheel?

[Beastlee]

16" for me.

Manufacturer's recommendation is 32 front, 29 rear, but most people choose their own preference. Mine is 34 front, 32 rear for normal day-to-day running. I'll go as high as 40 all round (measured when cold) if on track.

[Beastlee]

Yes, forgive me, that is the right way round for my figures. I would edit my earlier post but it would confuse matters. Mine should read 34 front 32 rear.

36 all round, its the pressure i have always used, and there one standard 16s....the noise is coming back now though, had 2 days of it gone, and now its coming back...wierd

You could try and clean the wheel / hub interface surfaces so they are nice and clean. Perhaps a thin film of copperslip on the hub surface too may help?

[pitslayer]

might be worth a try, will try getting them balanced aswell

clean the mating surfice yes

copper grease no, no, no, no, no, no well unless you want the wheel to fall off

i found something really wierd with one of the bbs alloys i took off. one of the eagle F1s, has the wierdest tyre wear i have ever seen. it has 2 cuts parrarlel to each other, which are going the opposite way to the tread.

[Beastlee]

Any pics? If it was feathering I would suggest perhaps alignment was out.

first i noticed this

where the splits are

no tread

[Beastlee]

Looks like I was on the right track......or the not so right track if you get the idea.

[psbarham]

they are pussy cracks, they apear when the car has been driven slowly and the tyres spend all their time cold

[White Lightning]

New seat of boots required then?

[pitslayer]

for those wheels yes, i took them off because they are getting up to the wear bars, so i put the facelifts on which have lovely new tyres well newish.
will be getting more for combe though

[DickBarton]

Looks like you have driven over something on the ground and it has cut - glass perhaps?

[shaun1978]

looks to me like that rough drive you have been going up at 200mph has ruptured the carcass of the tyre causing the tread to bleb, which means they are no longer perfectly round.

[pitslayer]

try 5mph. the cuts are in the opposite way of the tread
