I just acquired a 2012 Civic LX with stock 15" wheels. I also found a set of 2002 Accord 15" rims that I'm planning to mount snow tires on. Bolt pattern and hub bore match on both sets of wheels, but the Accord rims have a deeper offset (20mm deeper). I can find 20mm spacer/adapters for these. Three questions:
1- Do I need spacers or will the tires rub without them?
2- Will I harm my wheel bearings by adding these spacers?
3-Do I need to add spacers to the rear wheels, too?
Thanks in advance!

 

Are you sure that they have a 20mm different offset? Where did you source your information?

As for answering your questions directly, you should be fine running them without spacers and without rub, as long as the car isn't lowered. There won't be any issues with wear on the bearings as well.

 

1 - Doubt it
2 - No
3 - Doubt it.

 

Thanks for the responses...
Toyomatt, I measured the wheels to come up with the different offsets.
Chance EG, thanks for your answer,too. I need to put the Accord wheels on and look for problem signs, I guess.
I probably should've asked if the handling will change, beyond the difference between summer and snow tires, too.
Another thing that I wasn't aware of is that the snow tires (already mounted on the Accord rims) don't have TPMS sensors, and I'll be dealing with having the Traction Control setting stuck on. I'm not used to these modern 'features'...this Honda replaces my 99 Outback, and my last Honda was a late 70's Civic CVCC wagon
