Unofficial fixes / workaround & after market fixes

Blazeforth I've got the diesel and the suspension is so hard its ridiculous - like spine shattering hard - cars into dealers next week to be looked at and I will post if they change anything - if you want me to post part numbers tell me where to look for them and I will stick some pics on.

just pop under the back of your car, you can find the rear suspension. The part number is directed towards the tyre, but just wanted to compare the ones with updated suspension. My dealer told me they can't do that as it's not active for UK customers. It looks like this.

I've got it from another thread. No worries.

Some info for you.

We've been noticing that some cars are being delivered with Toyo Proxes with 100 weight loading, and some (mine) with Bridgestone 104 XL loading tyres.

As the CX60 does not require either of these levels of loading (92 would be perfectly fine), the tyres fitted are being over specified, which can certainly relate to the comfort levels we are experiencing.

XL (extra load) tyres are notorious for reducing ride quality and increasing cabin noise. They do have advantages also.


Toyos are naturally a forgiving soft tyre (with immense grip), and with the lack of reinforcement, they will be a whole lot comfier over the Bridgestones.

I'm going to make a thread about it once we have more info, I am trying to find a CX60 local using Toyo 100 tyres so I can compare the comfort levels. Certainly could be on to something here.

Bridgestone actually make the Alenza in 100 loading, but from what I can tell its more expensive than the 104, so this could explain why the 104 is fitted to mine.

On my recently acquired (March 2023) CX-60 PHEV Homura, I do have Bridgestone Alenza 235/50R20 100W. There is NO XL marking, so I appear to have the more expensive of the various options suggested above. My dealer has also assured me that I do have the revised factory fitted shock absorbers and that there is no requirement for any local dealer replacement (unlike other earlier PHEV vehicles in his custodianship). Might this explain why I am not moaning about the 'ride'?

Last night, I spoke with the couple that spent 650 miles in my back seats on a trip to the Yorkshire Dales and they assured me they have "never been in a more comfortable car", despite the steep hills and undulating country roads. There is no doubt that early CX-60 PHEVs had a troublesome ride, but has Mazda now got its act together?

I quote below from RAC Tyres. I am curious about the CX-60WAR suffix (Top brands and prices you'll love - RAC Tyres).

235/50R20 BST ALENZA1 100W CX-60WAR

The Bridgestone Alenza 001 has been developed for high performance SUVs and offers an all round reliable performance. As well as this, it has been engineered to offer high levels of safety, notably in terms of its confident braking and grip. Moreover, it is a durable tyre with low tread wear to be expected thanks to its specialised tread design.

• Designed for luxury SUVs
• Reduced tread wear and improved longevity
• Strong braking and grip

How odd that its designation appends CX-60WAR? Coincidence?

There shouldn't be an XL marking on a 100 weighting tyre I don't think? Im still in the infancy of my learning on this though.

XL loading tyres are 104+ I believe. And yes the 100 tyre on pretty much all tyre reseller websites is more expensive than the 104 strangely.

This certainly is starting to make sense now of why you appreciate the ride of the car so much more than I and others do . The guy who got his car with the Toyos 100 said it was much more comfortable than the one he test drove and didn't snap at potholes. Reading about the differences between reinforced XL tyres over standard literally echoes all of my thoughts about the ride especially its 'snappy' and aggression at pot holes.

The RAC quote is interesting to see. National tyres are quoting the 104 XL for my registration (and my previous PHEVs registration). The RAC quotes the same, however the guy above has the Diesel as well, and his has 100.

Sounds like Mazda either made a cockup, or have figured out what the culprit was/is.

I think there is something in this! No one wants to sit in the back of my car as they say it makes them feel sick all the small bouncing and motion from the road modulations.

I am at my dealer on Thursday, I am going to checkout their CX60 demo cars and see if any have the 100 tyres fitted and take it for a test drive. If all I need to do is put on a set of 100 loading tyres to fix the ride I will be one happy camper.

Apparently, in Poland, some cars are getting Toyos, and some Bridgestones, but no comments on the weight loading version they are.

Blimey! Is this a Eureka moment?

Frankly, I can’t believe the “CX-60WAR” suffix on the RAC Tyres website for my factory fitted tyre is mere coincidence?

On my housing estate we have some (in road) brick vehicle calming patterns that my former Mercedes E350D (and previous Jaguar XJL) with low profile run-flats shuddered over as if it was a cattle grid, but my CX-60 barely notices them. We also have two speed bumps and again, the Mazda is much better over them than the Mercedes, or Jaguars XL and XF. I imagine that this experience is not dissimilar to a comparison between 100W and the stiffer reinforced 104XL when fitted to the CX/60? Any thoughts SouthEastern?

I genuinely do believe that Mazda has probably sorted this out for later PHEVs. Or did I simply get lucky my car having been supplied with Bridgestone Alenza’s? But what is now the recommended tyre fit? Maybe others can comment stating their tyre and car date of acquisition?

I have also now had all the software upgrades listed by Ash8. However, I have never experienced the 12v battery issue, although have seen its nuisance on an earlier delivered showroom car. My doors and insulation also seem fine. Even my wireless charger stability seems to have improved since its software upgrade.

What is remarkable is after these software upgrades, my vehicle left the dealership with 20 miles greater estimated total mileage and yet my dealer added no petrol or charge. My next 100% home charge also estimated 36 miles EV, rather than the past typical 28, with the higher figure being closer to my actual experience (that is close to or occasionally exceeding the quoted 39). To be fair, external temperatures are currently much higher.

Early Mazda CX-60 PHEV reviews were justified, and maybe are still relevant for the diesel? But more recent reviews of the PHEV and customer experience seems to be better. Maybe tyre choice is more important than suspension?

I picked up my CX-60 a week ago, registered 30/12/22, VIN1128xx. It hadn’t been a demo but had been a director’s car within the dealership group, 1800 miles on clock.
My tyres are also the same as Noah’s it seems, please see photo. Absolutely no issue with the ride, over the moon with it all so far!

Having looked at mine properly now, I fear these tyre sites and their classifications against registration numbers could potentially be at fault.

Two of my tyres are 104xl and two are 100. I cant check the PHEV as its long gone so Ive gone off the registration on these sites which all quote 104 XL’s.

It seems like its had two new tyres at some point in its travels and they have basically just used a tyre service who has classified them like these sites have and fitted them. It does happen when they experience damage in shipping and transfer. I dont know how these classifications are done with the online sites but my car and the previous one are all quoted as having 104 XL’s, never an option for 100.

Sadly it does mean , although my ride will get better on the rear when i put 100’s on which will be welcomed, it won't entirely solve my issues with the comfort and ride. So back to waiting for Koni and their adaptive dampers.

Rules me out of fitting some of those Pirelli All Season Noise Cancelling ones though, cant take an £800 punt on XL’s even though being an all season they ‘may’ be better but they may also be worse!
