We’re now getting into our second year of iX possession, which suggests the start of our second winter with the automobile. Finally year, we acquired using the winter without difficulty, however, the automobile simply by no means felt significantly snug in low-grip situations. So, that is been excessive on my record of issues to handle earlier than the snow begins flying this year.
The iX has all-wheel drive commonplace due to its dual-motor configuration. That’s an enormous asset when the roads are coated in snow, however, the BMW nonetheless has some substantial issues working in opposition to it for low-grip driving. The most important difficulty? Weight. The iX weighs someplace around 5,700 kilos, and occasion probably the most superior stability management and braking programs cannot compensate for mass.
The opposite is huge difficulty was tired. The all-season Goodyear Eagle Touring tyres present a very good mix of grip, low noise and low rolling resistance regularly driving. Nevertheless, in tougher situations, they proved constant however lower than stellar. I wished one thing slightly extra confidence-inspiring.
I handled an identical scenario with our earlier EV, a Tesla Mannequin Y, by going to a devoted set of snow tyres for winter months. With the iX, I hoped to keep away from the trouble of swapping wheels and tyres every year.
Once I realised the ian Treatment WRG5, it appeared like an ideal answer. Nokian dubs this an “all-weather” tyre, threshing completely completing all yr lengthyearon roads moist or dry. But it surely gives an extra aggressive tyre ctyreund and tread sample to take care of the types of low-grip situations that Nokian’s winter tyres represent.

The corporate was type sufficient to supply a set for testing, however there w, as an issue: Nokian does not make a Treatment WRG5 within the 235/60R20 dimension that the iX xDrive50 rolls on by default. The closest they’d was 255/55R20, considerably wider and barely shorter.
Figuring out the iX was designed for tyres tyresoad as 275 for the M60 trim, I knew that becoming 255-section-width tyres tyres no difficulty within the fenders. There’s additionally the priority {that a} wider tyre wotyrepossibly really be worse for winter grip, as the traditional perception is that slender tyres are thresher. Nevertheless, I have been assured up to now by tyre entrees that—in most non-race conditions—wider remains to be higher, even in a low-grip setting.
So I put within the order, and certainly, the tyres match on the iX with no difficulty. What was stunning was how a lot of tyre purchases had already taken place on the inventory of Goodyear tyres Ttyresar two had been noticeably extra worn than the fronts, to not the purpose of the place they wanted to change, but definitely to the purpose the place lot of their finer tread was gone. My tyre tretyreauge reveals they’d about 1/4 of an inch of tread remaining after 12,500. Most consultants suggest changing typestyles as they get beneath 4/32 of an inch for wet or winter situations, so it is not nice to see them this worn after solely a year of driving.
The previous tires. You possibly can see that the rear tires (left) had been significantly extra worn-out than the entrance tires (proper), seemingly as a result of the iX sends extra energy to the rear wheels.
That is regardless of this factor largely being pushed for informal commuting and relaxed road-tripping. BMW really does not have a really helpful tyre rotation interval, however, when you have a jack and the requisite instruments, I’d recommend doing it each 5,000 miles or so.
Regardless, given the discount of tread on these two tyres, I used to be completely happy to be swapping on the extra aggressive Nokians earlier than the snow began flying.
Noise and Vary
Past the dimensions issues, I used to be additionally frightened that these further sipes would end in extra noise on dry asphalt, so I took some in-car recordings of the automobile on the previous tires eatyreofan swapping them out. On the identical stretch of dry asphalt, the Nokians measured constantly inside a decibel of Goodyears.
After which there’s the very queveryCertainly an extra winter-friendly tread and tyre compound will end in decreased effectivitycorrectorr? Preliminary checks really point out the opposite. On a 220-mile freeway take a look at the loop, the iX really used barely much less vitality than it did when working on the Goodyears on days with related temperatures (between 40 and 50 levels F), averaging 2.7 miles per kWh on the Nokians and a pair of.6 on the Goodyears.
Vary testing like this in the actual world is fickle at greatest, so I am not going to say the Nokians are literally extra environmenvironment-friendlyheless, that put to relaxation my concern that I might see one thing approaching the ten to fifteen % vary lower I’ve seen up to now when working a devoted snow tyre.
Lastly, I used to be additionally a bit frightened about how far off the speedometer could be, given the outer diameter of the brand new tyres is barely smaller than the previous one. I might finished the maths utilizing online conlineors however was very glad to see that the GPS-measured distinction at freeway speeds was lower than 1 mph.
Reboot
As we had been executing all this testing, we observed one thing was amiss with the iX: The hands-off Driving Help Skilled system wasn’t working. It did not give any errors or throw any alerts, it merely did not work on the freeway.
We additionally observed that the automobile refused to acknowledge any distant instructions. The iX had already confirmed fickle in coping with preconditioning requests or serving up details about cost standing and the like. However, now the,e factor was lifeless to the world so far as the MyBMW app was involved.
I used to be a bit frightened that there was one thing fallacious with the automobile’s onboard modem, however, after some Googling, my spouse learned of different individuals fixing related conditions by forcing the SUV to reboot itself. The method is not fairly so simple as the ol’ three-finger salute that Home wWindowscWindowss can be acquainted with for rebooting, but it surely’s not far off: Faucet the engine begin/cease button 3 times to enter diagnostic mode, then maintain down the quantity button for 30 seconds.
Several moments later, the automobile was again online unfortunately cruising up the freeway hands-free.
Now it is time to see how the brand-new tyres deal with the white stuff – assuming we get some this yr.
