Winters for '18 S60 T6 Dynamic with Sport Chassis
Hey,
I just picked up a 2018 S60 T6 Dynamic with the Sport Chasis. I wanted to buy winter rims and tires for the car and use only the Volvo prescribed size. for this particular model it seems volvo only endorses using the same rim and tire for winter as the summer. Any other S60 combination will cause a 4% speedometer error. The rim has a very large offset 55mm. its an 8Jx19x55 and the Tire is a 235/40R19. What are the best options? Buying new volvo OEM rims are expensive IMO and my 2018 doesn't need brand new rims. Kijiji and facebook market place barely has any options. Volvo dealer says Portia, Bor, Ixion, Artio or Polestar Rims ONLY. any suggestion? These options don't seem like ideal winter wheels. I currently have the portia rim on now with my summers. Open to all opinions and want to hear thoughts. Remember if I attempt to downsize and wish to keep using volve recomended tires sizes, then the overall wheel diameter will be smaller causing speedo and odometer error. IS there a method for electronically modifying the computer perhaps? IDK

Off size rims for winter tires
This is probably too late to help you but I just saw it.
4% error is tiny. The manufacturing error even with the factory rims probably can be larger than that. Tires of the same nominal size vary in diameter more than you would think.
My wife bought a 2018 S60 T6 with 18" rims. I found a set of used 17" volvo rims ( I think from a C30?) and used the winter tires from her toyota. They create a bit of spedometer error but not much. at 4% you might have an indicated 100 km/hr and be doing 104....
You can look up wheel specs to make sure bolt pattern, center bore dimension and offset are. Other Volvo models (nice because them come with volvo centers) and other manufacturers rims can be. This is a good site. Volvo S60 Wheel Size and Specs (wheelssize.com)
Look up the tires you have for summer tires and the tires you are thinking of using for winter tires on the smaller rims on a site like tire rack to see how comparable they are. The diferrence in diameter will be proportional to the speed error. ie a 4% smaller tire will over read speed by 4%.
17" or 18" rims would do you just fine with the right tires and be cheaper for the rims and tires. Generally you want a narrower tire for winter then most cars have on them for summer tires for traction in the winter.
Hope you were already successful or this helps.
