Best option here is find someone with an R Design fitted with 17" and swap wheels! 225/45/17 has plenty of sidewall to soak up bumps😀
But seriously, I agree the lowering springs coupled with a 35 profile will make for a firm ride... Just be careful changing tyre size with insurance, some will view the size change as a modification. Plenty of tyre calculators to show the difference in sizes, be worth a look.

Insurance can be very weird. The first thing to determine is whether any change you're considering is an "OEM" option, either a standard choice or available on other models in the same range.
If it's different size tyres and they're listed on the car sticker or in the manual I'd not worry.
If it's outside that they WILL want to know and might refute a claim if you hadn't told them. Standard kit they probably won't be too bothered about, but best to tell them.
That said, most companies are less picky about "sensible" mods these days and won't necessarily charge anything, they just want to know.

My insurers used to get really interested a decade or more ago in the fact that I fitted winter tyres, these days they couldn't care less!
Though they do want to know that I have two sets of wheels (winter and summer) as that's something I have to store when not in use so it is, to them, an extra risk. no charge though. Not on the V40 though as that has all-season tyres (Michelin Cross-Climate 2) that's my other car.

 

I have 235/35/19 as well. But I want to lower my ride. At the moment it’s quiet high. So lowering is the next step. Just not sure what to get it down to so that it doesn’t rub. It’s still standard from factory. Can someone guide me

 

If you are going to fit big rims with low profile tyres (and yeah you WILL have a much harsher ride - my V40T5XC is on 18" as std and its pretty harsh - then please fit bigger discs as they start to look too small in there. Also paint the calipers. Other comment is that you dont have the XC blacked out trimming so, particularly at the rear, the wheels look small for that haunch. Just saying.

 

While it costs more money, a height adjustable coilover setup could work in your favour...

 

Joining to the thread from a different direction wanting to go from 17'' to 19''

Looking to buy these beauties "Polestar Performance" 8 x 19", Volvo V40 with specifications as follows:

Model & model year	V40 2013-2019
Possible part numbers	31454840
Recommended tire size	235/35 R19
Color	965 (Silver)

I am driving 2012 V40 D3, oem sports suspension and rims Segomo 7,5 x 17'''

Two questions:
1. Fill they fit on my car?
2. Can i have them legally? Volvo approved 18'' and exceptionally 19'' from the factory..

Update on the above: after researching I grew more confident that there is no obstacle to putting even 20’’ wheels (with limiters installed), so when I’ve found the great deal for used OEM 19’’ I took it!
Super happy with the purchase and the look. It’s badass imo 🖤

Previous 17’’ wheel.

 

Have or will you lower it. I want to get 19" from stock 18" but i want to lower it too. Prefer the way a 19" fills the arch more but they like in your photos lift the car to look like a jeep.

Are you going for springs or coilovers or just leaving it as is.

 

I am running my V40 R Design on Eibach Pro-Kit lowering springs, replacing stock springs (Chinese made, apparently) that had both snapped at 50,000 miles! They make the car look much better, with no huge gap between wheel arch and tyre. This is the 3rd Volvo (totalling over 200,000 miles) that I have run on Eibachs and I am a huge fan. They are made in Romania, by a German company that only makes springs, so much better quality control than the standard Chinese made springs! Friends in the motor trade tell me that broken springs are now commonplace. I have also now swapped to my spare set of winter wheels (taken from my old 2011 V70) as an experiment. They are 245/40R18 Cratus wheels with Michelin Cross-Climate 2s on. They also fit, surprisingly. I thought the ET55 offset and 8" wheel depth (as opposed to the standard 7.5" on the Ixion IIIs) would cause issues, however it doesn't. I am very happy with the look. Caliper painting in the spring...

 

Hey great post! Can I ask if you have had any issues driving over speed bumps?

Cheers

 

No. I am always careful not to hit them too fast anyway There's no bottoming out, at all, but then I have fitted new springs and shocks (Sachs OEM) all round
