Is the suspension bad for you too? I've never been to Germany but the way journalists write about it, the roads are like the holy grail of spirit level surfaces

Sorry for my late reply, away on a business trip. That may have been the case 20 odd years ago, but nowadays, nope. It´s the same thing with the "unlimited speed limit myth on all motorways" Most Autobahns are now regulated, although a few are still "unlimited".

Did an interesting experiment today. See the tyre guidance above. This label confirms that my PHEV car was factory fitted and delivered with (Bridgestone) 235/50R20 100W tyres.

My dealer had inflated them to 39PSI and 45PSI as per the (label) recommendation for a fully laden vehicle. The ride has been satisfactory. Today, I tried dropping that to the lesser laden recommendation of 36/36 PSI and instantly it felt just like my former Mercedes, which had low profile run-flats, and juddered over potholes and traffic calmers. I have no such concerns about the ride at 39/45 PSI. Maybe this observation might help others running with these tyres at 36/36 PSI, which wasn’t a great experience for me compared to at 39/45 PSI.

I run 38psi all round, which will fluctuate to 39psi when warm.

Much more comfortable than running 36psi. 36psi just squirms and the potholes are worse. Its like it relies on the tyre wall to take all the impact and makes everything so much more harsh.

38psi improves more areas but does make some others slightly worse, but overall, 38psi is a much happier ride for me, the car also handles better , lighter steering and feels more spritely. 36psi just makes it feel bogged down.

40Ppsi is too hard and 36psi is too soft for me.

We are possibly not fully comparable SouthEastern as you are now driving the lighter diesel and were running 104XLs on the rear until a few days ago. I suspect the heavier PHEV might benefit from marginally higher PSI. What does your label suggest?

Where we clearly agree is that 36 PSI doesn’t offer an acceptable ride. But to be frank, had my dealer not opted for 39/45 PSI on delivery I would probably be running at 36/36 strictly following the label, when a tad more pressure patently does offer ride benefits.

The pressures are listed as the same for the both the PHEV and Diesel, but i never did play around with pressures on the PHEV.

I know a few others with the PhEV also prefer 38psi all round. Its personal preference i figure and based on the type of roads you encounter the most. Best to play around till you find the best for you.

But yes one thing is for sure, 36 is definitely the worst ride quality.

“The pressures are listed as the same for the both the PHEV and Diesel, but i never did play around with pressures on the PHEV”.

An interesting admission SouthEastern. I imagine this is quite common. I would never have departed from the label’s suggested 36 PSI had my wise dealer not inflated them prior to me collecting the vehicle to the higher range. I would have just moaned! He evidently had much insight, and I know has routinely being replacing shocks in earlier vehicles. For anybody not happy with the ride, trying higher tyre pressures is evidently worthwhile, but as you say, personal preference may play a role, and 36 PSI is definitely not where folk want to be.

Everyone changes pressures on their tyres to within the manufacturers range to find their ideal, its literally something that anyone with interest in cars does yet you hail it like its a revelation, its not, it's just that you've never done it before.

However the CX60 is quite contrary, and unlike normal cars that would be more comfortable on the lower end of the spec pressure, it works better with higher pressures (although I strongly advise not to be running 45psi unloaded as that will be like a set of ice skates in the winter, thats pretty silly tbh), primarily because of the poor dampers design.

It will never bring 'premium' levels of comfort but running say 38-39psi over 36psi mitigates some of the really bad issues, like the snappy compression over potholes, but an increase in road vibrations and more modulations are felt. Its driver preference really.

The good thing I'm finding from being part of this forum, despite (fully understandable and justified) differences of opinion, is that I'm picking up lots of useful tips. Who would have thought that tyre pressure would make a difference to ride quality in such a significant way for the CX60, especially when it would appear to be contradictory to normal experiences - I.e. lower pressure equals a more comfortable ride.

Sounds very much to me that a lot will be down to individual preference and taste, and I look forward to tinkering with mine in due course.

Thankfully, my current car has 20 inchers, so I'm used to cars which are in the firm side.

It generally what happens when suspension is too firm, the shocks are pressurised at frequencies way above normal use, so the manufacturer relies on the tyre pressure to mitigate this. Tiny pressure adjustments can make a big difference - think of a race car, very much little small bump 'give' because most race tracks are butter smooth, but tyre pressures are immensely important to get the best grip and lap times.

If you drive say An F-Pace on 22's with their 'Dynamic' adaptive dampers, the ride is beautiful, plush and soft but also firm. Thats a proper suspension design and it does mean that the wheel size doesn't necessarily need to be a factor in comfort and ride.

What car do you drive now?

Tiguan diesel (190 R-line).

Been a fantastic car over nearly 4 years and 70,000 miles. Not one real issue at all.

 

[UKPhil]

My car at delivery had way over pressured tyres. Can't remember what but it was like driving on rocks. After I realised and lowered to 36 the ride improved greatly.
Strangely a bit later my dealer called to update me on some issues and said "Mazda recommend lowering to 36 psi. for a better ride"!
I said that's what the car data plate and manual already say.
Currently on 38 all round . Noticing some light "feathering " on the outside of fronts after 6000 miles

I almost bought one of those but the interior was a bit agricultural for me, the exterior is great in R Line trim, why are you getting rid?

38 all round is the sweet spot for me.

Could need your tracking and camber doing if you’re seeing some outside wear?

I fancied a change and particularly liked the interior and styling of the CX60. Also, given I'm never going to go back to my 80s boy racer days, thought the pokiness of the PHEV would be fun.

 

[JimUK]

I’m in Warsaw this weekend and seeing lots of CX-60’s! 😀🇵🇱

 

[kowalcp2]

I'm in Rome 4 days and haven't seen any.

 

[Bogdanlex]

Hello all,

Did someone change the driveshaft and can share some post change impressions ? Are the vibrations gone ? It this the solution to get rid of the vibrations ?

They called me from Mazda Romania and informed me only that the TSB was released and that they will call me again when the new driveshaft will be delivered to them. This happened like a month ago.

Thanks for your feedback.

BR

Did a 600 mile journey across UK the past weekend.
Liked:

• averaged 38mpg on Petrol alone (I couldn't charge in between as most service stations only had the instavolt DC charging)
• it definitely got the pace and love it when accelerating away from roundabout.

New issues:

• A creaking sound when turning slowly, probably suspension
• driver side mirror wobbling. On rough motorways/Aroads driver side mirror got this wobbling issue.

Disliked:

• if EV is not engaged and when accelerate hard after a roundabout, the engine feels really rough.
• High road noise in motorways
• Fuel tank is really small, maximum I could get is 260 miles from petrol alone with full tank. May be I have refuelling issue?

 

[Minimhf]

Hi @Minimhf did you resolve the gearbox issue?

Hey, no I'm still getting random bouts of acceleration that aren't me doing it. It's not like pedal to the metal territory but a slight un-commanded increase in speed, usually when lifting off. It's almost as if it's leaving the clutch in too long while its rev matching the next lower gear.
In other news I'm now regularly kangaroo hopping at low speed, often when going up hill. I'm sticking on the list for when it's in for the latest recalls, so will see what they say then.

See my other post (in the ”positive” section):
- Mazda (your dealer)is able to “learn” or recalibrate the way the gear shifting operates.
This abrupt gear shifting is now gone and also the oscillating vibrating sound.
There is still a low hum, but not as irritating and loud.
