I need a diagnoasis

[sleepyrascal]

SYMPTOMS:

Front right tyre (from drivers point of view) is near slick in the centre. All other tyres are in perfect condition. I thought it was all the racing of the lights etc:I. You could expect one front to be slightly more worn perhaps but not to this degree. All tyres were of equal wear a few months ago.

On another note, I have a nail wedged in one of the rears. So suggestions for a low price high quality tyre??

Slick centre, and tread on the outside is a sign of over inflation.

What size is the tyre.

[sleepyrascal]

its on a 17". The tyres were inflated by BMW in Aberdeen.

Thats probably your problem then :p Does sound like excess pressure, definitely worth checking

And if you question them, the answer will be, did you check the pressures as stated in the handbook.


Still worth mentioning it to them though, can't hurt.

As for a replacement, it all depends if you want run flat or not.

The thread here (http://www.newminiscotland.co.uk/snitzforums/topic.asp?TOPIC_ID=3147) is about replacement tyres, and there will be plenty on M2 as well.

[sleepyrascal]

Ok nice one Duncan. Cheers. I forgot about that thread.

It will be over inflation. When you over inflate a tyre the centre of the tread bulges out as the bottom of your tyre essentially goes V shaped. Tut tut BMW Aberdeen!

SUB HUMAN SCUM JC!! :(

I wonder if I can pin this on them. I was getting some stuff done to the car before the loch ness run. When I picked up the car the service guy said he had filled the water, checked oil and tyre pressure.

[Gismo]

Tyre pressures change daily, especially with the dramatic temp change we have been having lately, i doubt if any garage, including JC's would accept liability in this instance.
It is the owner's responsibility to ensure that the correct pressures are in their tyres for their particular needs.
Same goes for the oil and water levels :(

[Duncan Stewart]

It is worth spending a few quid on a tyre pressure gauge and keeping it in the car so you can check regularly. I do this but still find the fronts wear more in the middle, pressure is the recommended 35psi which is higher than any other car I have owned.

[KenL]

What was the psi in the tyre?

I check mine every week when I wash my car along with oil and fluid levels.

Duncan, that seems a bit high, especially as you're wearing the tyre, are you using the guide on the inside of the drivers door for the correct pressure

[MartinSullivan]

These are the pressures out of the manual for the standard tyre combinations

First figure is in bar then the ones in brackets are kPa and finally psi

Some good articles on tyres, pressures, wear etc can be found here (http://www.tirerack.com/tires/tiretech/general/pressure.jsp) - just use the pull down menu to select the articles

[duncan]

Fair enough Martin, but the MINI stuff is for the North American market.

I'd check the UK owners handbook.

[MartinSullivan]

Cheers Duncan, just checked figures are correct as per the UK spec manual - only difference is tyre is spelt incorrectly :D Saves me scanning the page in again - if anyone prints it out just tippex out the word tire and replace it with tyre :D

Just noticed my manual does differ from the chart for 175/65 R15 tyres it quotes 2.1(210/30) for fronts and 2.4(240/35) rears with two people.

[duncan]

Its probably the same, just they can't spell the word tyre properly! :D

well I will be digging out my manual as soon as I get home as I am sure manual says 35psi front, 30psi back with two people, 35/35 with full load!

[MartinSullivan]

Page 79 Duncan!, my manual does differ from the chart for 175/65 R15 tyres it quotes 2.1(210/30) for fronts and 2.4(240/35) rears with two people. Is that what you have?

[Duncan Stewart]

Doh! I was talking b*llocks :eek::I:clown:
Curiosity got the better of me and I went out to the carpark to check.
The door pillar sticker says 2.1 bar front, 2.4 bar rear, so I also then checked my actual tyre pressure which are correct. Interesting to see two different versions for the rear though

Duncan - when I was running 15" tyres, I found that the grip increased quite dramatically when i lowered the pressure to 30 all round (as shown above). I got a good even wear rate at that pressure even with quite a bit of very hard driving.

The amount of grip on the car when i got it was very poor... dealer had given it to me with the tyres at 45psi!!

[Duncan Stewart]

Cheers Rob. I think I will give it a go as it feels a bit "light" sometimes although it holds on OK.

[Wul]

Rob - the cars arrive with a higher pressure to increase their clearance on the transporter - part of the PDI procedure is to reduce this back to "normal" pressures - tut tut to your dealer!

[sleepyrascal]

Had to replace the balded tyre at my expense, plus I had a punctured rear. The tyres were months away from needing replaced so i just changed the whole lot! £580. OUCH!

GULP OUCH :(:blackeye::eek::disapprove: was that the best price you could get?

[sleepyrascal]

that was kenway tyres. It was £640 to start with and I got it down to £580.

[Big Col]

<splutters> £580!!! <feels faint>

Did you try Colins in Dyce? I got 17'' runflats for £117 - which would be £468 for four
