Hint on selecting car trailer mudguards.
Firstly measure the diameter of your tyre, add on the clearance front and back,this will give you the mudguards diameter.In general 50 mm clearance is okay so add 100mm to the tyres diameter.Then measure the tyres width,add on any clearance that you need this will give you the mudguards width. The width really doesn't want to go past the bulge part on the outside of the tyre.It's okay to go all the way to the chassis on the inside if you want.
