Hello all,

I currently drive 2015 C400, and the tire sizes on the wheels are as following:
FRONT 225/45R18 95H
REAR 245/40R18 97H

If I install 4 winter tires with the same size of 225/45R18 95H, would it affect my vehicle(such as suspension and major issues). These sizes are just for winter. Thank you everyone!

You'll be fine.

I am running those size tires on my C400.
They are the Nokian WRG3 all weather and I run them year round. No issues after 2 years

So you also use same tire size on 4 of them?

user 29474838

yes, all 4 are 225/45/R18

You use them for every seasons? I just heard some tech guys saying it will affect the engine and its ability of handling high speed as time passes by. haha.. I think I will use them for same size as you do, seems you don't have any issues for your C400 yet. BTW, does your C400 have any front lower control arms problem, like it makes sounds when your front wheels are running over speed bumps and uneven path? Thank you.

Absolutely no issues in 2 years.
All weather tires are good for summer & winter. They will wear faster than summer tires due to the softer tread.
a 245/40/18 is the same diameter as a 225/45/18 that's why they can have 2 different sizes on the same car.
Ask any tire dealer.
