How on earth did i get this flat spot?

I recently had a tyre (on the steering axle) changed due to a ‘flat spot’. Seems quite fisable but when the rest of the circumfrence of said tyre is at 6 milimetres people (depot manager) start asking questions.

Now I’m asking the question “How could could this possibly happen?”

I had something similar once, in the brakes a bit of the cam had broken off and dropped down so forcing the brake to stay on that wheel only.

Surely you would have felt that through the steering yeah?

It has got to be a fault in the tyre surely?

I put that one to my boss as I cant offer an explanation bearing in mind the rest of the tyre is 6 millimetres.

That’s what makes me think compound failure, for it to be on 1 tyre and only 1 part, can’t be anything else.

Has the tyre had a major repair at some point? They often wear more at this point becuase the repairs are done with a different rubber compound usually.

Not to my knowledge, thanks for your input though.

Had that before, ATS man said it was probably a heavy spot in the tyre itself :wink: :wink: HTH

A couple of thoughts:
Tyre fault - is the tread at the bald point “loose”, you can sometimes tell if there is a hollow point, by tapping around the tyre tread and hearing a change in sound.
Has that wheel been parked in a puddle of diesel for any length of time - diesel makes tyres degrade if exposed for a prolonged time.

i,ve just took one off my front steer that looked like a 50p peice, put a new one on and got the bloke to do the alignment and all is well now
btw a few year back i had 2 new michelins on the front go like 50p,s after about 5k michelin bloke came and collected them and 3 weeks later sent me 2 new new ones to ATS as there was a fault in the ones he took away

we used to get 50p type tyres now and then on the steer and especially midlifts…it was usually traced to faulty shock absorbers allowing the type to patter on the road.
can also be faulty tyre casings.

A flat spot in a steer tyre that is down to 6mm is almost certainly down to the age of the tyre, basically it’s [zb]ed, the casing could be out of round so that bit wears quicker, it could just be the rubber compound itself, unless it’s been skidded flat :wink:
