On the stock 235/40/18 profile, I once did a state highway run where the road was very gravely but didn't quite hit any bad pothole - yet I came back home to a scrubbed sidewall with small cuts all over it. I seriously considered dropping to 17 inches as well when a Volvo group member suggested the 245/45 upgrade.

Going to 16/17 inches will still give you much better ride quality though. So weigh your options.

One thing I am quite convinced is Id like to drop down to 225/50 R17's . I am facing the same issues you have mentioned above. Manufacturers should definitely take care of these issues being well aware of the state of roads in our country. It is a matter of safety.

On another note, would you know how much the 17" alloys will cost? any good brand you could recommend? I dont want to go for unbranded ones. I reside in Gurgaon.

BBS, Borbet and OZ Racing 17 inches will cost you between 1.2 to 1.5 lakhs for set of 4. I am talking about the base ones and not light weight wheels.
MSW by OZ will come between 80k to 1 lakhs.
Momo, Lenso etc will come around 50k to 60k.

I would recommend OZ Racing or BBS if you have plans to keep the car for few years, worth the investment. MSW is good too with TUV, JWL certified.

I have the same car i.e. 2015 S60 D4 which also came with 18 inch wheels so fully understand your plight. Four years ago I switched to 17 inch BBS alloys with 225/50 Michelin Pilot Sport 4. The change was totally worth it and I havent looked back. The increased sidewall height improved the ride and allows me to take on bad roads with much more confidence.

[vjbox]

Wow, this is quite a timing for me as I have been contemplating downgrading to 17" from the 18" that my V40 Cross Country is riding on for better ride quality. I just replaced the Pirellis at 22K as they had an uneven wear and since Michelins weren't available last year, I had to again order a new set of Pirellis. Now the global supply issue seems to have been resolved mostly and stocks are back I am told.

But when I asked around, both with the dealer and external garages, they didn't recommend that since it would supposedly affect the steering, suspension etc and I was asked to stick to the stock spec. I checked on the Volvo site and it does seem to list 17" wheels with 225/50 R17 tyres as approved for the car. I know they need to recalibrate things once you move to a new wheel/tyre size as it affects the speedometer, ABS, ESP etc.

I am always being extra cautious when going on longer road trips and slow down considerably when encountering rough/bad patches of roads where other cars would otherwise zip through. I do get odd stares from people in the process. I just don't want a tyre burst in the middle of a trip and the extra side profile will certainly help a great deal.

Just wondering how to go about!

I think I’ll go for MOMO or Lenso. I don't have a budget of spending 2-2.25 lacs. I will need to buy all 4 tyres as well. So those will also cost around 50k. Car is 6 years old almost, has another 4 to go at most.

That is all I wanted to hear. You went exactly what I am going through. It’s painful mentally and financially, plus you really can’t have a stress-free drive with these tyres. You are a wiser person than I am that you did this four years ago while my lightbulb has come on now. Haha. Thank you so much. Really appreciate your help!!! I've decided, I'm copying your setup. Hehehe

Just reconfirm with your Volvo dealer once that there is enough clearance for the brakes, and ensure no more than a 2% difference in the overall diameter.

Manufacturers are really brain-dead to be choosing such big rims + short tyre sidewalls for India. I have repaired my 530d's rims like 10 times for bends in 6 years of ownership. Luckily, I haven't faced any ruptured tyre yet.

I recently took an S-Class riding on ridiculous 20" rims to Lonavla! Ended up coming home with the space saver. Front tyre totally damaged on a rough road (not even a pothole):

That seems painful, I had the same issue while coming back from Lucknow and in my experience its the best highway in India at the moment. It blew out but very slowly I guess somehow made it back to Delhi. It was quite an ordeal. I’d love nothing more than go for a 16” even if it means compromising the visual appeal of the car. I have seen many S60’s with 16”. But unfortunately Volvo Gurgaon service center told me 16” won’t be possible. I’ll still check it , if so then 16”. But I’m sure as hell not sticking to these ones

hi kratant ,

before you make the final switch can you just reconfirm if all the ratings (load rating /speed rating/ maker specific mark( eg porsche gets N-0) if any of the tyres met the company spec.

i used to be wary of low profiles on my cayenne also but once i lost my way on long drive ended up on non existent roads in MP . since i was wary of being lost i didn't even think about tires once till i reached home . total damage to the PIRELLI P0 N0 tires ..none !!
since you mention bulging and cracking again if you have the fight left in you for another round of experiment try 5 psi higher than what you are filling presently. with a higher higher pressure and higher load rated tyre you might just solve your premature tyre failure .
PS: its safety matter and i hope you understand its totally your call

Given that the car was sold internationally with 16" rims, I think you should try importing them through a trusted distributor.

Well, the car is higher up the food chain in India than most Eu nations. Hence, I'll not be surprised in the lowest variant (with the 16" rims) sold in the EU didn't make it to the Indian showroom.

Just a note: When you have a puncture in the front tire, replace it with the rear tire and put the donut spare in place of the rear tire. 80-90% of the cars weight is on the front wheels while braking and a situation of having 2 extremely different tire sizes can cause unexpected skids despite the best high-tech safety systems.

Keep in mind that Volvo wheels have a relatively rare PCD (5x108), perhaps shared only with JLR among mainstream models in India. Options could be limited. Getting appropriate spigot rings for aftermarket wheels when going for the cheaper brands. A loss of 10mm width (225 vs 235) is hardly a difference, a better tyre compound will compensate for grip, steering feedback etc.

My personal suggestion would be to get used OE 17" wheels in case you can find affordable ones and you could have them inspected for major bends/repairs before purchase.

But Volvo also have much smaller output powertrain options internationally like their D2/D3 or T3 variants etc depending on market and model years. I am fairly sure that different/smaller brake sizes would have been used then including 16" options which may not be possible with brakes on OP's D5 variant.

Easiest way to check wheel/brake size difference for variants/markets is to use a aftermarket online brake catalogue (I prefer Brembo).

[Turbanator]

I will first change the profile to 45 as suggested by another member before downsizing to 17. Should work if you are reasonably attentive.

Also, try to stick with Michelin, PS4S if you can find.

Thank you so much for your advise, really appreciate it. I however as you mentioned have no fight left in me. To try out your suggestion I will have to buy another 235/4- R18 first, as at the moment my car is standing on three 235's and one space saver. Its happened so much that Id rather get rid of these. Driving a lot from Gurgaon to Kanpur, the road is outstanding but due to speeds the PSI as it is shoots up. Even tried Nitrogen, to no avail. I am going to get my tyres and rims changed. Need stress free drives. City or Highway.

Useful information indeed!! I never thought about it that way. I just didnt go above 40kph. I shall keep this in mind, and spread this knowledge as well!

A better ride quality would be very welcome in my car. Its so stiff, my Yaris and Innova have a wayyyy better ride quality than my S60. The change in tire profile would be very welcome, in fact a lighter steering too!!

Oh ok this is the first I am hearing of re calibration, as I wasn't aware of it. Will Volvo do it?

Michelin is the tyre everyone has suggested either the Pilot sport 4 or primacy 4. Ill go for Michelin and nothing else now.

I doubt that is possible given OP's car is the S60 and not the Cross Country variant which gives more buffer space in the wheel arches. Even then I doubt if one can directly go for a higher profile tyre on the same 18" rims as the tyres could rub the wheel arches at extreme steering. This is precisely what I had asked the Volvo technicians for my V40 CC if I can go for 225/50/R18 instead of the current 225/45/R18 to improve the ride quality but they turned it down as it is not approved by Volvo and they mentioned it would compromise steering and suspension so I had to ultimately back off. The only official way is for me to go down to 17" rims which allows me to go for 225/50/R17s.

On that note this is what Volvo site says for the approved dimensions for V40 CC.I am sure OP can get similar approved spec for his S60 as well.

I also get fed up sometimes with repairing the rims. It's a ritual twice a year unfailingly to pay 4 - 5k for fixing a bent rim.

Pic from yesterday. Rear left is damaged:

[kratant]

Finally got them changed. I went for Yokohama Blue Earth-1 (225/50 R17) and Momo Alloys. Total damage done was 91k. But worth it for the peace of mind. Ride quality is incredible. I should have done this a few years ago.

A thousand thanks to everyone who has replied , and given their valuable suggestions. To those who are suffering from what I have gone through, please go ahead and read this post. It is quite helpful.

^ thanks for the update. Please make sure to check your air pressure (cold) once a week without fail and maintain it accurately. You may move the frequency of this inspection to twice a week if not finding any variance week on week. Use a portable inflator with digital display for accuracy.
