Costco Steel Rims
I recently bought a set of steel rims (snow tires winter use) for my 97 Nissan Maxima at Costco. The brand is Macpek. From the catalog, the recommended model is X41552 and the alternate model is X42554. The particular branch I visited only carried the alternate and I bought a set. They are 15x6 with 5x114.3 bolt pattern. They are universal fit and hence are lug-centric instead of hub-centric.
I intend to place the tires on the car myself and and hence I took the Cost rims and snow tires to a local garage to have them mounted and balanced. Upon installing the tires on my car, I realized that the lug holes on the Costco rims are a bit larger than the originals for my Maxima. I check the lug hole size against my 04 Honda Accord rims and the ones from Costco are still bigger.
Here's my problems:
1) I understand the rims will not fit the hub, but what if it doesn't even have a tight fit on the lugs? How can I ever centered them properly?
2) Is it normal for the lug holes to be bigger?
3) Perhaps there are new bolts that can solve my problems?
4) My original maxima rims are 6.5" wide. The costco rims are 6" wide. Any problems going to a thinner rim even though I am using the same size tires?
5) Would a hub adapter solve my problems?
6) I have an impact wrench from [rfdlink=/forums/autolink/redirectpage.php?linkid=24]Canadian Tire[/rfdlink] which I bought for wheel swapping. Understanding the recommended torque for wheels is about 90lb/ft, would my 228lb/ft impact wrench which doesn't not have torque adjustment be a problem? Potential damages?
Thanks in advance for any responses.
