40 profile will increase your wheel circumference and you will need to recalibrate the speedometer at the dealer. Officially Volvo will probably tell you that they can't guarantee wider and higher profile will not rub on smth inside the arch as they have nothing to gain from it but everything to lose if you do damage it - so it will need to be a friendly tech who wheel try and check it for you. In Europe deviation from standard tyre spec can be grounds to invalidate your insurance. With extra width you will have extra 5mm stepping out of the arch and throwing mud and stones back at the car. Just seems like a lot of headache and question marks. I'd just match the tyres.

 

I personally would go wider 285/35 not taller 40. You will be just fine with few mm more width plus looks better too ;-) Plus more tire choices with 285/35 and cheaper too!

 

It would create extra noise and higher riding discomfort before all

 

I really wish you would stop posting this nonsense. You have no idea of what you're trying to speak to.

-----------------------

To respond to the OP's question ill be swapping to a 285/35/22 the day our R-Design arrives.
I don't see an issue with it fitting and no need for re-calibration. I've up-sized on countless AWD and never had an issue besides being a MPH off when at highway speeds.

 

Technically 285/35R22 is actually closer to the stock 275/45R20's than the 275/35R22's (+0.4% vs. -0.6%) so well within mileage/size adjustment limits. 285/40 may or may not fit but will definitely require recalibration as it's over 4% larger. You'd probably need to do a bunch of measurements on clearance of the current tires (loaded, full turn, incline) around wheel wells, fenders, internal suspension and nuts/bolts.

Here's a great tool (I pre-fitted a few of my guesses though I have no clue what the offset on those wheels is and I assume they're 9.5" wide w/ an offset of 45)

http://www.wheel-size.com/calc/?whe...T45&wheel2=285-40-22X9.5ET45&wheel3=285-35-22X10ET60&fcl=25mm&wcl=25mm&scl=25mm

The key parts is the clearance at the bottom. On the same 9.5/45 rim, you'd lose 5mm to the fender and 5mm to the wheel well (thanks to extra 10mm in width) and lose 18mm to the wheel well or anything above the tire (extra 36mm sidewall, 18mm above and below)

Overall though I'd second brutus. 285/35 gets you a little more height, a little more width and *should* (not an official statement) fit. Plus the choices and prices in that size is the sweet spot of low profile 22" rims until you go into the full out F150 truck style tires (305/40 or 45 R22)

 

There is also another member on this forum running 285s for past 5K miles and installed by the dealer.

 

Also note the 18mm bump would realistically raise your car (and its center of mass) by 18mm too and definitely alter driving characteristics along with more sidewall. Softer ride, less sporty.

On a side note, did you get air suspension with your car? I just ordered this set as summer tires and am wondering what ride quality is like on them without the air suspension.

 

Thanks everyone.. And great replies.. Yes have air suspension and more inclined towards 285/35. On rise quality you do feel the bumps but to be honest I had the q7 with the same tyre profile so I am used to the feel of ten road. You will
Get used to it

Yes, but will my wife get used to it?

 

One last question, do I need to recalibrate anything if I went with 285/35?

What matters is the diameter of wheel aplus tyre.
To find out how things are when using different wheels/tyres, find one of the many calculators
on the web that allow you to compare sizes so you will see what the difference is.
http://www.willtheyfit.com/index.ph...285&aspect2=35&diameter2=21&wheelwidth2=9.5&offset2=20&Submit=Calculate#content
You can play with the figures until the difference is small enough to be ignored.
And knowing the difference will allow you to decide if settings need to be changed.

 

I have over the years driven on 275 and 285 and have noticed that the comfort does go up purely because with the extra width the pothole is covered and the car glides through it, meaning to say if the width was narrower the car goes into the pot hole. Regarding the noise I have not noticed much difference due to old age. And yes the tyre choices are a lot in 285/35.

Just one last question on TPMS. How will this work with the new tyres? Where is this sensor?

Sensor (unless there's something special about volvo tpms) is attached to the wheel at the air valve. As long as whoever is switching your tires isn't a complete buffoon and breaks the sensors while taking off the tire you should be able to re-use the sensor and just put on the new tire.

 

This has gone a little off topic. OP asked if he could use wider profile tyres and someone confirmed that they are using them so it's not an issue.

 

Thanks trigger happy. So the sensor is inside the tyre?

Yes, it is:

Reviving an old thread. Has anyone else tried the 285/35/22 on their stock rims? Would love to hear how they are holding up and whether it looks funny. Thanks!
