Do you guys think buying from tyres for a Merc not marked MO will make a massive difference to the wear ?

Just had 2 Michelin Pilot Sport 5’s on but somebody said tyres made for Mercedes marked MO would have been better and the wear slower on the inside.

(The last set i had wore very quickly on both inside edges)

I imagine wear will be more on MO tyres. The reason being wear rates typically aren’t top priority for manufacturer tyres.


They’ll be more fussed about things like efficiency, wet braking and wet handling - these will typically come at the cost of wear.


At least with Michelin PS4Ss, manufacturer versions wear quicker than stock ones from the reviews I’ve seen online.

No difference in 99% of cars.

Very few cars actually have tyres created for them. M cars, Porsches etc. are the exception.

What's the car?

Efficiency (or lower rolling resistance) is actually good for wear. This is usually at the expense of braking and handling.

BMW PS4S tyres use more of the softer compound when used on M cars, actually for the opposite reason to wet handling. They want the best lap times and 0-60 times. These cars aren't focused on efficiency or wet lap performance. It is most likely true for any car that is performance orientated enough to have PS4S as it's OEM tyre.

It has a softer gripper black carbon, more of it, and is combined with a silica compound similar to Cup 2 tyres which is worse in the wet.

The BMW * marked tyre is a lot worse in the wet, but way better in the dry.

Always a bit bemused by these kind of tyres for daily driving in the UK given there are performance tyres which will cope far better with the normal range of conditions in the UK, the 0-60 difference isn't noticeable in person in comparison and while the ability to lap a demanding circuit will be noticeable most people won't have that level of skill or even doing that.

I'm kind of wanting the impossible but can't find a tyre which combines everything I want - looking for a tyre which combines at least basic all-season capability (doesn't need to be proper all-season) with good dry braking distance which also is light off-road capable, low rolling resistance, good ability to handle torque and not soft. Anything which seems to manage to cover both good dry braking with some all-season performance seems to have a reputation for being soft and not handling torque well.
 
how much does price matter ? Cross-climate 2's are still little more expensive than my Goodyear efficient grips - so when my time comes I will think about changing one axle.

on pricing, though, this had been interesting

New EU worn tyre rules could save 400m tyres and £5.9 billion a year | Auto Express

Tyres at the 1.6mm legal minimum tread depth must still meet same performance standards as new tyres, says the EU
www.autoexpress.co.uk www.autoexpress.co.uk
so eu will impose a new standard on car tyres which will mandate that manufacturers have to give them better grip when worn, without a price increase ?

Not worried about price, but ideally I want something which stops in the dry in much shorter distance than all-seasons while still having better than summer tyre capability in a contingency - I've got better options if it is properly wintery.

What is noticeable with the BMW * marked tyres is how the tyre feels and the feedback, especially on M cars.

Kinergy 4S2 (4S2x suv). From tyre review:

"The Hankook Kinergy 4S2 was the best in dry handling, the best in wet braking, good around the wet handling lap, good in dry braking, and was comfortable. It did lose out in the snow compared to the best, but as I said at the start of this, I would rather have an all season tyre that's good in the dry and the wet than one that excels in snow, that's what a winter tyre is for afterall. Once again the Hankook has the balance of an all season I really like."
 
I just had a set of pilot sport 4's fitted, been running those tyres about 5-6 years now, but man are they expensive. For my car £150 per tyre, vs about £120 for something like Goodyear efficient grip.

I don't do extreme mileage, but I live in a rural area so do a fair bit of driving a lot of which is NSL, so makes sense to have decent tyres, but I'm honestly going to have to consider maybe going with something else next time given those prices.

If you think the Goodyear's, that's £60 cheaper for a set, or a bill of £240 Vs £300, that's a fair amount of cash saved and I wonder really, if the extra is worth it.
 
Depends a bit what you drive and how you drive is albeit the emergency services tend to use the Goodyears quite a bit - they are fairly decent. I wouldn't be in a hurry to put PS4s on the Qashqai for example hah - albeit it is quite torquey but the steering/handling in general would not make them worth it :s

I'd kind of discounted them due to so-so aquaplaning resistance - this is the problem I can find tyres which tick most of the boxes but always fall down on one of the requirements :(

There's not going to be a tyre that's great at absolutely everything.

You want the dry braking of a summer tyre, the all round capability of an all season, some off road ability, efficient, enough grip to deal with big torque, isn't soft, resists aquaplaning... The only thing you've not mentioned is wet braking :p

This newer generation of all seasons is almost certainly going to be the closest thing you can get to a 'do it all' tyre.

FWIW I've had the Kinergy 4S2 on the rear of the 440i over winter and they were spot on.

Closest I've seen so far is the Pirelli Cinturato but they aren't available for my vehicle, most of these tyres do well enough in wet braking other than the budget options.

Thing is I'd happily trade some of the winter handling capabilities of all-season for better dry handling, I'm kind of falling out of love with the braking distance in the dry on all-season and how they can become sloppy in weather like we've got at the moment, but I do need some better than summer tyre abilities in inclement weather for contingency - if it is proper wintery I can swap the wheels out for better winter options.

Have you ever aquaplaned? I don't think in any car, on any tyre, I've ever had this / experienced this issue. :)

I haven't so far when I'm driving, I've been in other people's cars where it has happened though - a lot of that due to budget tyres :s

I spend a fair bit up and down the A30 and A303 dual-carriageway sections and definitely like confident feeling tyres when passing lorries in torrential rain, etc. which the last few months especially has happened a lot. My summer tyres have been Bridgestone Turanza t005 and Conti PremiumContact6 which are decent in the rain but the Qashqai is on Avon ZX7s which are a long way below those in the rain.

I'm in a bit of an odd position in respect to where I live and journeys I do in that while 95+% of the time I don't need anything other than summer tyres, in that up to 5% of the time there is no substitute for something which performs better than summer tyres but I rarely need to go to the full compromise of all-seasons and if it is properly wintery I have other options.
 
I have a 2021 Nissan Leaf Tekna EV that I bought a month or so ago. Between the day I test drove it and a week later they replaced three of the Goodyear Efficient Grip Performance with a pair of garbage Sunny Sport Macro tyres on the front lerft and rear right and a Delmax Sport on the front right. These tyres are abysmal!! On Friday I overtook a tractor and the front tyres tramlined the center lines in the road which gave me a brown trouser moment and on Saturday night in the rain on a twisty road I could feel the car sliding all over the place so these are going sooner rather than later before they kill me. The thing is I am stuck on what to go for. The tyre size is 205/50 Z17 and they must be XL rated. I am leaning towards all season tyres as they need to be able to cope with the snow we have in NE Scotland but also be good in the wet. I had Hankook Kinergy 4S2's on my B-Max and they were excellent all rounders but my economy dropped by 5-6mpg so not ideal for a EV. I know Michelin Cross Climate 2 are excellent but that's a hell of a lot of money for four tyres.

I haven't completely ruled out a summer tyre but there is very little in the way of winter test results on these. I have had Goodyear Efficient Grip Performance on other cars and grip in the snow wasn't too bad but I didn't like the soft tyre walls. I have found the Michelin E-Primacy for £145 a corner and a extra 15% off four tyres but I can't find any winter data on them. Same thing with the Bridgestone Turanza 6 but the tread pattern doesn't look too good for use in the snow.

Any suggestions from the OCUK experts would be much appreciated.

I have the previous Turanza t005 which are very similar tyres and anything other than light snow they struggle - one of the reasons for my posts above. I don't believe the 6 are any different in that respect.

There is an all season version of the 6 which is supposed to be a decent all rounder but I've not tried it.

My C63 is on P4S tyres. The previous owner replaced one due to damage so now I have one that needs replacing and another at 7ishmm. Not sure if I should replace both or just the one. If I replace both I'm putting Goodyear Eagle F1's on. 265/35/19 pricing is obscene. I can put 275/35/19s on for much less.
