Do any Yeti owners have any views on the pros and cons of running their tyres at the "eco" pressure shown on the label inside the fuel filler flap?  I understand from the manual that it's supposed to improve mpg - but does it make the ride harsher, or have any other adverse effects?

 

The reason I am prompted to ask is because my tyre pressure warning light came on the other day.  I stopped and had a look at the tyres but they all seemed OK.  I drove the short remaining distance home and let the car cool down, then checked the tyres.  I found the front nearside was at the "eco" pressure of 2.5bar whereas the rest were at 2.2bar, which the label inside the fuel filler flap indicates is the nominal pressure for the car when part laden.  I will admit that I'd never consciously noticed the "eco" pressure setting on the label before.

 

I assume it must have been like that for a week or so, dating back to when I had had the NSF tyre replaced and the front wheels re-aligned due to excessive wear on the outer shoulder of the NSF tyre.  I'm a bit disappointed that the garage that did the work, which I usually trust to do a decent job, had apparently not thought to check the pressure in the existing good tyres before inflating the new one.  But in the long run I think no significant harm was done in this instance.

 

This is only the second time I've had the tyre pressure warning warning light come on.  The first time was after I'd had to fit the spare - which is a bit smaller than the normal wheel+tyre - after ripping the sidewall of the OSF on a sharp piece of protruding kerbstone ☹️ (no chance of fixing that with goo!)  In that instance the light came on after about ten miles of driving, which I thought seemed like rather a long distance to cover before the computer decided that the wheel revolutions were significantly unmatched.  In this more recent instance I'd probably covered about 50 miles before the light came on, which seems even worse - although I suppose the actual difference in the rolling diameter between the same tyre at 2.5bar and 2.2bar is likely quite small.  Nonetheless, it does reinforce my view that the tyre pressure monitoring system is really only useful as a warning in the event of a fairly major deflation - in other words, the kind you'd expect to notice anyway? - and is no substitute for regularly checking tyre pressures (which I admit I probably should have done as a matter of course after the new tyre was fitted, just in case).

If the garage that replaced the tyre or if you had “reset” the TPMS you would not have gotten any warning and would have been oblivious to the fact that one tyre was inflated to 2.5 bar. Which shows the benefits of checking tyre pressures regularly and resetting the TPMS as required.

In the instance when you fitted the spare wheel, if you had reset the TPMS, no warning would have incurred.

ej, most of what you have written is correct.

The difference in pressures is very small, but coupled with a new tyre understandable.

I have run the pressures as per the fuel cap many times, loaded or just two of us.

Of course the more pressure the harder the ride.

Most of the time I run the pressure at 2.2bar, unless going 4 up or heavy weight in boot.

Adjust all pressures, then on level ground re-set your TPS.

And, the only person to set the pressures right, is going to be you. 😄

 

Ps. When I go out on the bike, I check pressures every time.

Not so often in the car though. 🤔

2.5bar is too crashy for me.

 

2.2 is what I go with unless loaded and towing.

 

 

I also find the 2.5bar eco pressures far too hard for me, coupled with the less than ideal Goodyear efficient grip tyres which I believe are the bigger culprit.

However I run at 2.4bar and find things are much more to my liking in noise, harshness and grip  .. I know its not much of a change but it makes me content. The Goodyear's are not long for this life so maybe I will like the eco setting on what I believe to be a better tyre of my choosing.

2.2 all round with Goodyear 225/50 R17  EFFIGRIPERF 2 98W XL  feels (and sounds) just right.

Rarely more than the two of us in the car and any trip luggage never weighs more than an extra adult in the back.

I run 3bar all round with no issues. The ride is unimportant to me as it's a works vehicle and always fully loaded.

What is it that you find 'less than ideal' about them?

 

I have them and have no cause for complaint although living in the hot and dry Spanish climate clearly my demands from tyres are going to be considerably different to yours in the the UK!

 

They were originally on the back of the car with a pair of crummy but near new Champiron VP1's on the front. Those were quite noisy however swapping the Goodyears to the front made a dramatic difference to that.

 

I'm no fan of odd tyres so near new or not the Champirons are going in favour of another pair of Goodyears.

Champiro appear to be a budget Chinese brand.  The reviews in the UK aren't too bad, but from my point of view tyres and brakes are the last thing I would economise on.

The Purchase price of tyres is not an indication of safety or grip / traction / friction.

 

The OEM tyre fitment of tyres from the biggest most well known brands fitted by the biggest car manufacturers can be real horror shows.

ECO Tyres that some might run at ECO tyre pressures and that might leave a Dealers from a PDI over inflated and as they were when the car was In Transit.

Even run at sensible pressures they might well be OK as Summer tyres if the Summer is dry and warm but as 'All year round' and use all around the UK they may be no better than Ditch Finders, actually worse than tyres that are inexpensive and made under names owned by the Major Tyre Companies and equal to the Parent Companies tyres.

eg Michelin own Kieber, Tigar, Riken,Kormoran, Uniroyaland BF Goodrich, then ATS Euromaster & BlackCircles where you might be able to get these brands.

Michelin Primacy 4 are not Budget but ECO and fitted to maybe get economy and range with EV's rather than Security, gtip, traction and short braking distances. 

 

What are fitted as OEM on Soft roaders / AWD's and imported to the UK in strange sizes for those that need All Weather / All Season or Winter tyres is ridiculous in this day and age. 

 

As to Brakes, that is something that VW Group penny pinch on and replacements that are superior to OEM need not be expensive to exceed the standard discs and pads and may not rust in front of your eyes.

Tyres in my opinion are very subjective, my beef with these Goodyear's are on Scottish rough road surfaces (by design for rain & winter ice/snow) incredibly noisy and harsh riding at any pressure, the 2.4bar I stated is about bearable for me, plus although I have had the 4-wheel alignment checked several times I dont like the lack of grip in the wet ... I find them fairly dreadful compared to any Uniroyal or Nokian I have had in the past albeit on other cars.

 

To balance that I did find them much quieter on German, Austrian and even Italian motorways ... so its maybe horses for courses, but in the wet, wet West Coast of Scotland where summer is 27mins on a random day at the end of June they get a big thumbs down from me.

 

As I said my opinion 

Edited 17 October, 20214 yr by TruckbusUK

Subjective indeed.

 

100% diametrically opposed to you here in Spain dry performance and road noise are my equal principal bullet points.

 

If buying 4 new tyres today I'd probably plump for Hankook, Michelin Primacy might be fractionally better but IMO not worth the £40 price differential.

I find pretty much the same with Primacy 3's on my Yeti, I live near the peak district and drive through it most weeks. Badly surfaced roads with wet/cold conditions mostly, mud, leaves etc.

 

The Michelin's feel too hard, noisy, skippy, easy to break traction and downright dangerous once the temps drop below 7 degrees and we are getting to that now.

 

So even though they are only half worn they've been removed and a set of Crossclimate 2's fitted. Feel's much better now.

3 bar ? That's 43.5 psi. Far too high surely. Must be bouncing all over the road. Probably only the centre part of the tread touching the road. What's the recommended pressures for your model ? In the event of an accident whether your fault or not if the pressures are checked by an insurance assessor they may well look for anyone or anything to point the blame at. And they do.

Your concern is noted. And your view on how much tyre is in contact with the road or how much bounce there is doesn't concern me or my tyre fitter who commented last week when he changed my winter tyres that they always wear evenly.

On my Greenline I run at 2.15 bar all round, usually just 2 of us aboard.

The label inside the fuel filler flap on my Yeti seems to allow up to 3 bar when the vehicle is fully loaded, which Rustynuts says his usually is:

 

 

(I have to say it's not entirely clear why there are two figures under each load category, nor why they're the same in each category except for the fully loaded case.)

Simple. 16" or 17" wheels for the rows, and in each case the left figure is the front tyres, the right the rrears. I do get concerned when people talk about tyre pressures without ensuring that they are referring to the same size. Obviously in this case it doesn't matter, but on some types of cars there are various diameters, widths and aspect ratios used, and sometimes extra load or non extra load, and these may have very different pressures.

Front and rear.

Now we have sorted the tyre pressures out:

Can we now talk about Oil?

 

🤣🤣

 

 

Funny this sort of subject.

Near on every Forum, Bike or Car, Oil & Tyres seem to be the top subjects.

I think the 3 bar is the pressure for the trailer tyres that will be carrying the 5 suitcases for the 5 occupants of the Yeti!!!

That's a lot of difference between 2.4 bar recommended for front tyres of a fully loaded car and 3 bar.

What are you trying to say with your obscure comment and awarding of yet another "groan" Llanigraham?
