It is an MOT failure. The tyres I use. Bridgestone Potenza RE050A are Asymmetric (A) and seem to wear well.

 

Hi there.

My first day on this forum and I to had very similar tyre wear on my Mazda 5 Sport. I noticed a week or two after purchasing the vehicle, used, from my local main dealer. My local tyre specialist suggested that this wear on the inside of the tyres, on one the canvas was showing through, was almost certainly caused by the previous owner stradling the speed restriction pillows in the road at high speed. I now tend to drive over them,sedately, with two whhels on and two off. I hope this helps.

Hmm, sounds like the dealer is feeding you a load of cobblers to me. Read through this thread and I'm sure you'll see why. There are so many of us with this issue and I very much doubt that we have been driving wildly over the humps! ( I certainly don't and have had significant inner tyre wear.) Mazda know there is an issue but don't want to admit it, this has been the case for a few years now I think. I'd keep a close eye on your new tyres if I were you and keep the pressures up.

 

How many of these pillows do you have around where you (and the previous owner) drive? I get the inner-edge wear problem, but am fortunate to not have any of these pillows on the roads I normally drive on.

If you look through this thread you'll see that some posters have had the problem apparently fixed with a 4 wheel alignment (Rhrodri), and others with a change of Tyre (NickC). There are also unfortunates like me who are still getting the problem despite trying various tyres and having several alignments. My remedy at the moment is to just use budget tyres and flip them after about 8000 miles (switch over the front wheels AND flip the tyre on the rim - this way the directional tread still points in the right direction, but the inner edge becomes the outer edge). At the moment I've got LingLongs on the front, £58 each. I'll give an update on the wear at 8000 miles.

One thing I've not tried are the more expensive tyres that other's say don't have the problem. I've seen posts saying the following tyres do not wear on the inside edge, and people have got over 20k on them:

Bridgestones,
Continental Contisports,
Michelin Primacy

Also, there's almost a consensus on this forum that the recommended pressures are too low, after my first tyres went I started keeping them at 36psi instead of 32psi, and reckon I got a few thousand more miles out of the tyres as a result (was getting outer edge wear too at 32 psi).

Good luck

 

I think you can get a cream for that.

 

2009 2.0D Sport

have read this forum thread on off for many months. Here's my report

So 20k reached.

2050's are now down to smooth on inside front and rear edges Rotated at 9k miles. (i bought fr dealer at 6 mo. with 7k miles). I ran tyre pressures higher than dealer I guess (34-36 front, 34-38 at back dep on weather load etc.)

From reading this forum, 20k on the 2050;s seems about right. It is probably too late to complain to Mazda (as I have no intention of buying new tyres at the dealer, I doubt I can blag a free alignment let alone geom check there, which is the best i could squeeze out of them at 20k and 2.5 years old).

So time for new tyres:

I have spent huge hours on internet looking at reviews (mostly in german) and prices. A few here on this thread have mentioned their decisions on replacement tyres. One of big probs with reviews is that they are for a certain size (rarely our 205/50.r17 93V or W) and the tyres' standards can vary massively within a given model (esp diff load ratings eg. 89 v. 93)

All seasons are not avail for the above size in Europe (excepting Vredestein.Quat.Lite but few reviews). If I go to winter tyres next year I will go for 16 in (15in dont fit) so should solve wear there (assuming its the 17's that botch Mazda's camber design thus causing the front wheel wear problem on the facelift 5)

So it's Summer tyres; which? In the performance realm, the Conti's Sports 2, 3, or 5 all get good reviews All cost ca.£530 delivered. Seems the wear in 5's (reviewed for a similar size to 205/50r1793v) is potentially very severe (German track reports) and they are sticky. methinks too much Mazda5-disease wear to justify 600 odd quid. Avon's are cheap as performance (e.g. Four (4x) Avon ZV5 205/50/17 R17 W93 Set of Tyres XL | eBay) but crap reviews. Mich.Primacy too dear (you guys said wear does not justify price). Other contenders e.g. goodyear efficientgrip get poorish reviews for price. PIRELLI CINTURATO P7's are thus my choice in this category (top reviews in sizes close to mine for: wear, wet stopping, comfort&noise, comprimise of rolling resist v. cornering stickiness.

Or BUDGET, the barum-bravuris (as someone mentioned) get top reviews for their class. They are the cheapo from COntinental made in Romania or other eastern EU. They are ca. 310 quid from tyre trader (aka National on ebay but w. cahsback)

The p7's are about £490 delivered.

What would you do. If the Bravuris are as sticky as the german reviews claim, the mazda5 might eat these up in 10k (even with higher tyre pressure). But if the Pirelli P7's wear quick, they will look pretty exprensive pretty soon. I'd like to think I could get 30k out of them. None of the tyres are non-asymmetric so no flippning on the rim, only front to back rotating.

Oh, and at my 2nd svc (5 months ago massively expensive like my first as you all know) both rear schocks had gone - the or was leaking! Same the service was AFTER my summer in the Alps and autobahn (DPF clearout time). Both repl. FOC under warr. In many ways this p*sses me off more than the tyre wear. 15k from a set of shocks! Can someone tell me how to bust this new set before the warrantee runs out in July cuz after that me and the dealer is goind our separate wayz.

Other than a Crankshaft sensor failure (mis-repaired by the dealer!) at 12k I do like the car as a sporty yet functional family car and other gripes apply at least as much to other comparable cars

Had the barum's Bravarius 2s on for a few months now after getting them dealer fitted with the free geo checks there.
Personally, I won't buy them again, and not something I would have chose. The dealer recomended them. They are a touch noisier than the Falkens I had before, and a bit less grip. The plus with them is I actually expect the inner edge wear to dissapear, despite the geo check. Thats because they are almost like a truck tyre in construction, with the edge having a clear defined seperate layer, and a squarer definition from the tread to the sidewall profile.
Hope I am explaining it well enough, but other tyres go from the tread to sidewall in a more continued, rounded action.
Time will tell, as I have about 2K on them at the mo, and the problems were appearing at 5-6K.

I have also been lead to beleive that tyres must be XL rated, but not seen that in writing, just probably dealer BS, trying to blame the wear on me again!


I prefered the Falkens 452 that I have used on more than one car, with good results and a good price, if you want budget.

I have found this site recently: Cheap Car Tyres Online » FREE DELIVERY » Oponeo.co.uk

They certainly seem a lot cheaper for my bike tyres, but not compared them for the car. They are based in germany I beleive, and people I know using them report good service and about 2-3 day delivery.
Never known ebay to be the cheapest place for tyres, I usually use mytyres or Black Circles

 

Hi all,
I have just been through the same process as Mark. I have replaced all 4 tyres with Kumho KH-31. Total cost £343. Only done 250miles so far so cannot comment too much but they seem okay. Noise definitely seems to vary more with different road surfaces compared with my previous ones. The Kumhos are asymetric and XL rated. I believe XL may be something to do with having more reinforcement.
Previous tyres were Michelins and Goodyear. The Michelins did over 22000 mostly on the front and the Goodyears did 27500. Tyre wear was fairly even - lowest was 1.8mm. Pressures have been maintained at 33-34
psi (i.e. as recommended) - virtually all driving done with only me or plus wife in the car.

Like others have commented I could not justify paying over double for Michelins and it came down to either Kumhos or Falkens. Only reason for going for Kumhos was they were about £10 ea less.

if u can afford them and want a decent grippy tyre Falken 452's they cost around £75 a corner from Camskill (then u need to get fitted).

 

Another vote for Camskill here. I find they, or a local independent, are the cheapest. The multiples do not even come close.

My current fronts are Falken FK452s at 36psi. They are coming to end of life and I would say they are just OK for the money. I found that they lost traction (accelerating from standstill) more often than other tyres I have tried (Bridgestone RE050, Conti SportContact2, standard Dunlops), and no, I don't think I am particularly aggressive at the lights

I have ordered the Hankook K110 (£87.40 +Del) and shall see if the extra money makes any difference compared to the FK452s. My alternative would have been the Uniroyal Rainsport2 (£88.80 +del). I have not heard a Mazda5 owner talk about either of these yet.
