Brand of bike you have, tells Me nothing ,
Do you want to wait until someone who bought your same bike to answer?
take a seat..
Id guess you need clearance over the tire .under the mudguard for snow?
a possible kludge.. cut the mudguard where it will be too close ..
and continue from that cut, with a bracket spanning the interruption..
I have my front mudguard mounted on either side of my fork crown,
so underside of the crown is the low point..
