I recently purchased a 2017 Forester 2.5 Touring and installed a winter wheel and tire package on the vehicle. Let me help you save some time and frustration that I experienced so you don't have to go through the same ordeal that I went through. This took multiple trips to the tire shop to get right. I have used these guys for the last 10 years and have had no issues whatsoever, but I was swapping winter tires on OEM wheels and not using aftermarket wheels.
The entire vehicle was vibrating at highway speed (70mph and up)
Here is the setup
- Nokian Hakkapaleta R2 225/17/60
- Pacer 83B steel wheels 5x100 17
I went with 17 tires and steel wheels because of Chicagoland winters and notorious potholes. Plus the wheels are going to get beat up by all of the salt and steel wheels are less expensive to repair than aluminum. I also didn't want to spend a lot of money.
The shop I go to uses a road force balancer and they did rebalance and move one tire on the wheel one visit. They also tried different lug nuts that fit better on the steel rim than the OEM ones. Finally after much research I asked about a hub centric ring? A 56.1mm to 72mm poly carbonate ring was installed and seem to eliminate 95% of the vibration. Winter tires are not going to have the same ride comfort as an all season or summer tire. I've drive Nokian WRG3 all year on my other cars, but that is an all weather tire and not a full winter tire. Those tires are very good but they do not offer the same traction as a full winter tire setup. With a Subaru, the WRG3's are probably good enough but I have the OEM wheels to run a summer set so I figured I would go with a no compromise setup this time around.
The take away is that, if you are running aftermarket wheels that are "lug centric," you must run a hub centric ring to make sure the wheel is as centered as possible. Otherwise you will get vibration at highway speeds.
Finally, the Subaru all wheel drive with Nokian Hakka R2's is the most sure fitted setup I've ever driven in winter. I highly recommend these tires.
