Front Tyre edge wear

[AlanTR]

After 22,000 miles on my 21 plate Crosstar there is excessive wear on the edges of the front tyres. The service sheet shows the tread depth as 4 mm and the edge wear was logged as an advisory on the MOT.

The tyres are Dunlop Enasave EC300+ 185/60/R16 86H. We are in our mid-70s so there has been no hard cornering! Obviously it would be a good idea to have an alignment check.

Has anyone experienced similar excessive front tyre edge wear on their Mk 4 Jazz?

It maybe you have hit a pot hole and its skewed the alignment of the wheel tracking . While not enough to notice on tbe steering  wheel central position it  may have caused it over a good distance . The high torque of the electric drive motor can add to the wear if you set off briskly from a tee junction.. however if you drive smoothly as i try to (mostly..) its simply going to be wheel alignment .?

If the outside edges of both front tyres are wearing faster than the centre of the tyre it will be due to low tyre pressures.  I had this on my Mk2 Jazz.  Add 2psi to the manufacturers recommendation next time you add air to your tyres.  Do it first thing in the morning before the tyres are warmed by the sun or driving.

Just how bad is this  'edge wear'.   Have they logged the 4mm depth at the edges, or are the tyres mostly 4mm with even balder edges?   If they are noticeably bald then  the tracking/tyre pressure may be relevant.

     Some eco type tyres come with less than 7mm tread when new,  so still having 4mm remaining at the edges   after 20,000 miles is not a bad rate of front tyre wear. You may get more than this if its mostly motorway miles,  but  the Mk4 has incredible torque from rest, and even older drivers might get more front tyre wear than expected without being boy racers.   

They may still have  quite a lot of mileage left in them. The advisory might just be because they may not last another 12500 miles  service interval  .

A couple of weeks ago I noticed some wear on the outer edge of my front nearside which I’ve not seen before. an SR,26 months old and only 7500 gentle miles. Driving is nearly all local. Took it to nearest tyre place who told me to replace both fronts as they also had some small age cracks in between treads-and check alignment,£320!
Tried a second one they too said same and wanted £240 for same. As I was near to Kwikfit as well I called in. They said nothing wrong with the tyres or slight age cracks and didn’t need alignment checking.
Lastly on way home I called at the local garage that normally service my cars (who are not tyre retailers)when not using the free service offer I’ve got on the car. They also said nothing wrong with tyres and asked if I have a lot right hand turns on my usual routes as this can be cause of slightly more wear on the tyre. Which I actually do.Also said they’ll easily last me until next year when I’ll probably change car anyway.Interestingly he said they don’t use OEM tyres like the Yokohama as they wear too quickly. They also service all the local ambulances and fit lesser know tyres to them( can’t remember the makes) and they get 30k out of them!
So in the end I’ve not had them changed but I’ll keep an eye on them.

OEM tyres are often a collaboration between tyre maker and car maker to achieve the best possible results for  the cars official emissions rating, noise level etc.  1mm or so less tread depth when new reduces rolling resistance and noise by a small amount, which might be just enough to achieve a lower banding for tax/emission zone advantages.   They also recommend higher tyre pressure than used to be the case for the same reasons.  The car maker doesnt care if you have to replace the tyres sooner, and for the tyre maker its a plus. 

Its always been the case if your typical  mileage involves a lot of  bends and turns  that your nearside front tyre  gets a bit more  than its fair share of outer edge wear. Even if you dont drive the car like you stole it.
  I used to have a sharp U turn on my daily commute. Over the full  life of the tyres my nearside front outer edge had about 0.5mm more wear than elsewhere. I could replace both front tyres while they were between the legal minimum of 1.6mm and the minimum 3mm recommended by the tyre industry.  So I never bothered messing about rotating tyres. (rotating left to right is a problem with directional tyres anyway)  There was nothing wrong with tracking.

another reason - from another post - why I get the tyres rotated from front to back - also I get usually in excess of 30000 miles per set. driving is most up to speed limit, in small town and a roads very little motorway.

Thanks for the various responses.

The front tyres are worn on the inner and outer edges (a bit more on the outer, as you would expect) which normally indicates under inflation. I check my tyres pressures regularly when "cold" and always maintain the pressures as per Honda specs.

Obviously I need to increase the tyre pressures - too late for the current front tyres which I have carefully inspected this morning. The guide for minimum depth is 1.6 mm over 0.75 of the central part of the tyre, my fronts are 4 mm in the central part but are barely compliant on the outer part. New tyres required.

The current Dunlop tyres have good reviews so no worries there.

Several aspects to this as previously mentioned.
I worked in design/development in the car industry and yes, the OE tyres are very likely not the same as you will get as aftermarket even if the reference is the same for reasons discussed.
Electric/hybrid cars tend to be heavy,  and torque from standstill is often quite high. Near full lock on the steering there is often quite a lot of scrub and wheel camber angles can get exaggerated,  not normally an issue and a result of compromise to achieve good turning circles with higher speed handling. If you do a lot of full lock turns it can accelerate edge/shoulder wear.
Road surfaces in some regions can be quite abrasive too, depending on weather,  hills etc, and what sort of grit is used locally.
Sounds like your tyres still have a bit of safe service life left if you've had several opinions which you trust.

I’d swap the front tyres and rear tyres around. Probably cost a tenner at best. Should even out the wear and maximise the use of the set of 4. I’ve always done this on my car with the intention to replace all 4 tyres at once every few years.

I would certainly NOT move front tires (that need replacing according to Alan TR) to the rear. That's where the best tires should be!

100% agree.

Any council road calming humps along your regular route?
Used to be common around cities who were hell bent in stopping cars being used on rat runs or slowing stolen vehicles being hammered at night.

Reading this post has prompted me to check the tyres on my new Mk4 Advance (3 weeks old & 550 miles) which was supplied with Yokohama Blue-earth-A tyres.
Tread depth is only 6.5 mm which I guess, confirms what others have said, regarding OE tyres.

For comparison, maybe someone can tell us the tread depth, of a new Non OEM Yokohama tyre?

Please also have a look at https://www.honda.co.uk/cars/sitemap.html with special regard to the "Tyre label sheet" of the respective models. Interestingly, there is no mention of the Yokohama tyres for the Jazz 
Please also note, that Honda seems not to care about the Jazz owners because there is no tyre listed with a wet grip rating better than B (the majority being C - or worse) where as the HRV comes with Michelin tyres with an A rating - go figure!

(btw: That's why I leaned on my dealership to have Michelin Primacy 4+ installed instead of the crappy BlueEarth things and I am more than pleased with my choice!)
