Anyone else experiencing very pronounced feathering of the front tyres on their PHEV. (mine is a 2016 model, but only 14000 miles on clock). When I brought the subject up at the dealership during a service, I was told this was normal, due to the square shape of the tyre walls which was necessary for the tyre monitoring system to function properly. Also, if much driving is done in 'ECO' mode, this effectively makes the vehicle front wheel drive for better efficiency, thus producing more wear on outside edge. I run my tyres at the pressures for ECO driving, but do constantly use the ECO mode. Anyone else with any experience of this? I still appear to have a good 3-4mm tread across the tyre except for the extreme outside edge, which now has zero and appears to have very slight hairline cracking. The NSF is the worst, and service manager said this was normal.

The feathering is just a symptom of the tracking needing adjustment.
Your dealer is a lazy idiot.
ECO button does not make the car front wheel drive. It simply remaps the throttle pedal and tries to reduce the intervention of the ICE (petrol engine), it also reduces the efficiency of the heater or air conditioning.

Have fun!

I've rarely read such bollocks. Switch dealers now.
This one couldn't service a pram.

There are no "pressures for ECO driving." The ECO button only shifts some parameters that influence fuel efficiency - minimally or not at all in my experience. It changes nothing in the drive train. 4WD has nothing to do with it.

Running the car with the tracking out of adjustment will wear your tyres down very quickly. This is costing you money as the tyres, by your description, are illegal already.

My mistake guys, the service garage stated the wear problem was the shape of the tyre wall profile being 'square' rather than rounded, which was necessary for the tyre monitoring system to function properly. The part I wrote about the ECO button producing two wheel drive, I had read somewhere else. Didn't mean to cause confusion....was the early hours of the morning when I posted it and wasn't thinking clearly...lol. When I wrote 'also' previously, that was me jumping from what the garage said to what id read, but it was poorly written. Apologies.
When I asked the service dept about swapping the front tyre to the back to extend life, they said they would need to do some kind of resetting/recalibrating so that the monitoring system re recognised the wheel/tyre and there would be a cost for each wheel.

So basically, no one else had any problems with tyre wear.

I have included pictures below. Rear tyre no feathering, OSF showing slight feathering and NSF showing severe feathering.

So consensus is, it is not normal tyre wear?

Yes - very clear tracking maladjustment wear. Square tyres is really nonsense.

cheers jaapv, I felt the same, but the manager fooled me initially as he knew it would be the nearside showing the most wear, before I had even explained to him the problem, so lulled me into thinking it was common.

Will go back to him now and ask for it to be put in writing that it is normal wear, so that I can challenge Mitsubishi themselves. Hate being fobbed off through being ignorant of the mechanics.


Thanks.

I would let a Tyrenet specialist do the adjusting in any case. I think Mitsubishi owes you a couple of tyres.

Looks to me like a combination of under-inflation* and bad alignment. Get a 4-wheel alignment from someone who knows what they're doing (i.e., not this idiot).

*—not necessarily less than the recommended figure in the door jamb, but under-inflated for your driving style. Add 10% and see how you get on (all four tyres must be the same pressure).

Hi richi,

I'm 38psi all round, regularly checked, but I do get slagged off by wife and friend for being 'joe slow' when driving(rarely above 50mph). I would have thought slow driving would have been better for tyre wear!

Any recommendations for 'alignment' specialists in Scotland? As it is, we don't even have many mitsi dealerships!!!
Any of the 'kwikfit' type companies any good?

Failing that, it looks like a longish trip to get it checked. :-(

38 sounds about right. If you go over 40 the car gets rather bouncy and uncomfortable.
