if the pcd is the same then yes. et50 is 5mm closer to the strut than et45. so std cup alloys are et65 with 20mm spacers there et45 and they come to almost flush with the wing lip . an et50 would be 5mm further in than them
check centre bore aswell make sure spigot rings are available. think renault are 66,1mm o/d/. but dont quote me. at a quick glance they are 67.1mm. this could be an issue. yours are 66.1mm not sure you can buy a 1mm spigot ring. someone else may know
Ive been told that 1mm is nothing to worry about as the taper on the wheel bolts will keep them in the right position
bolts holds wheels on the car. the hub carries the weight.thats not the correct way to fit them. you risk bolts bending as the tensile strength of a wheel bolt is designed longitudinally not vertically.just saying
The hub doesn't carry anything, spigot rings are not needed at all providing you have torqued everything properly
