Don't know if the offset, pcd, bore etc are interchangeable or not, but they are the key elements. Offset can be adjusted out a bit with spacers if needed, but if the hub and studs are the same, not a change of fitting them to the hubs.
Regards tires, that's about a 3.5% difference, so your speedo and mileage counter will be off a bit. You'll be doing about 72.5mph when speedo shows 70, 93.2 for 90mph, if speedo is actually accurate of course, most overread a bit.
Not ideal as suggested max difference is 2.5% I think, but might as well use them and then replace with the proper size. Saves paying £80 to swap over and put in bin.
