Hi all,

would it be classed as normal for a Michelin Sport 225 40 18" to wear so much in 5000 miles?

Last service the two fronts were reading (N/S) 4-3-4 and (O/S) 3-3-3.

Now the O/S is completely worn in the middle and desperately needing a change (just right for the Christmas pocket ) N/S has lots of wear left.

Car doesn't pull or wobble at speed so I don't think there is a balance or tracking problem.

If it's a soft compound then yes.

Basically the better the tyre is at road holding then yes and in your driving style then even more.

The more expensive brands don't last as long as the budget tyres.

the wear in the middle of the tyre is a sign that you are putting too much pressure in it (hence the middle has more contact with the road surface) and if it is worn more on the inside/outside only it's a tracking issue. Finally worn tyre walls are a sign of too little pressue in the tyres

I would suggest getting your allignment done- or a fast road set up if your feeling flush, and checking the tyre pressure in the worn tyre, wear in the middle suggest over inflation

Always a stickler for tyre pressure, they suggest 36 psi for the front which it always is every couple of weeks I check them. Surely they would both have worn if this was the case.

I agree with what others have said.

Centre wear is definitely a sign of over inflation. Also, I think there might be a tracking issue so I would get it checked.

Pilot Sports are quite a soft compound however, I got around 12k miles on a set of fronts. Depends on driving style to some degree.

What does the Treadwear figure say?:

220.

With standard modern tyre construction you would have to be heavily over inflated for this to be the case i.e. over the max side wall pressure.

I usually run somewhere between what it states on the door frame and the sidewall max and I still find the shoulders wear first.

make sure its a proper centre with the computer 4 wheel laser alignment, I got ours done at the Honda dealer FOC when we bought the car but they only had the basic 4 wheel laser alignment that most tyre companies have were you don't get a print out and use a pc and even though the car drove true the results when at ABP were shocking, toe on NSF -0.1 OSF -0.8 (outside Honda spec) never mind all the cambers etc but I knew the Honda dealer could not do these with there basic equipment.

My advice go to ABP before the new year as they have a special offer on fast road setup (I had a mild one so to increase tyre life) as this is £160 at the moment instead of around £230. I know £160 is a lot of money but proper 4 wheel laser alignment will cost around £60 and they will not do the rear or cambers so it is a compromise + £160 is nothing compared to the price of 4 tyres and for the recored I think Michelin are one of the hardest wearing tyres you can get.

You are over inflating them... it should be 33psi for 225/40/18 on the Civic. Although I doubt that 3 psi would cause that much wear in the middle. If tyres are worn there is no point getting tracking done as they won't run true.

First get new tyres and then get tracking done. Most tyre places over inflate so check your pressure after.

Door sticker (new one obviously when 18" fitted) says 36 front and 35 back.

Were do you get the info for correct pressure if you don't go by what the sticker says...?

Those are diesel tyre pressures. I have 18" blades (on a 1.8 like yours) and they are rolling on 33psi front and back as per door sticker/manual/wiki

Drop your tyre pressure to 33psi trust me

I have yet to experience a tyre that wears in the middle first.

I even used to run my Civic Hybrid at around 40psi, and the wear was very even. Tyres used to last 20k+ like that.

If you go as low as the door sticker, the ride comfort is great, but the shoulders always wear way before their time.

I think manufacturers typically tend under cook the pressures a little to err on the side of ride quality.

but tyre wear in the middle alone is a sign off over inflation

 

[bodgerx]

It can be, but they would have to be significantly overinflated on radial tyres to see that.

A few PSI over shouldn't make too much difference.

Depends on loading as well; weight in the car etc.

true and also depends when the tyre pressure was checked.

Always check pressure when cold as air expands once it is heated and thus return incorrect tyre pressures

tyre pressure

hi i have same wheels i put 34psi in front 32psi in rear have no problems of abnormal tyre wear

the problem described relates to tyre wear in the middle. if tyre is worn in the middle section the main cause of this is too much pressure in the tyre which leads to the middle section having more contact with the surface. In your case your are 1 psi over the recommended which imo would not make a difference.

Excessive Tyre wear on the inside or outside relates to tracking
