I am sorry to say this pram is NOT compatible with different wheels, meaning I cannot recommend you any wheels that would fit any make your days easier. If I should suggest something, I would say buy a pushchair (not a system) not, with LARGE wheels for snow. You will, however, find other niggles with it - it will be heavier, bulkier... but better for terrain and snow.
Maybe, if the budget is limited, go for a second-hand for-now stroller and keep this you already have for later use (in spring+). A used Brtax B-Motion 3 Plus, for example, could word for worse terrain conditions. Fix your front wheels, as well, when going over snowy terrain - it will help slightly
And do remember, no stroller is friends with snow, pushing through the snow will always be a bit of a struggle. Larger wheels and/or fixing your wheels will, in any case, help.
