Default My new OE wheels don't fit on the rear

First nice day, thought I'd put my new wheels on.

start on passenger side.

front wheel goes on fine.

rear wheel doesn't seem to slide on all the way... doesn't seem to fit over the hub ring? it goes on partially, but the bolts look too short for the nuts and it doesn't sit flush against the rotors all the way around... what can i do?

wheels are 17x9.5 set, 54mm offset, 70.3 hub size
car is 1995 firebird

The hubs on the 93 up to about 96 are slightly larger, so you'll need to use a dremel tool with a sanding drum on it and take a little bit off the inside of the wheel hubs until the wheels side all the way on.
BTW you might as well do all 4 wheels, then you can rotate you tires.

Bingo. Had to do the same thing on some wheels for my old 93 Z28.

Thanks for the reply guys! Something I can try, doesn't seem too hard, but I wonder... is this the recommended solution or is there a "better" way? If I took it to a tire shop how would they fix the problem?

It's really not a big deal to do at all because even if the hub doesn't fit perfect it won't matter, the wheels are lug centric so the hub doesn't matter too much

How well do the center on the wheel balancer after the centers are opened up??

Perfectly fine in my experience, the difference in hub sizes is something like 3 hundredths of and inch. Not enough to screw things up

You aren't taking much off, not nearly enough to affect the balance. You just turn on the dremel and run it around the bore a bit. It'll look like you're just scuffing it up, but just wipe it down to get the dust off and the wheels will go right on. The first time I did it I just used sandpaper and did it by hand. It's easy.

OP -

Alternatively, jack up your car's rear end, block the front wheels, remove the rear wheels, then re-install a couple of lug nuts (per side), put the car in gear, and then let the spinning wheel act as a lathe, and (using sand paper) "sand" the outer surface of the hub vs. sanding the rims themselves.

I was not worried about current balance ...
I was worried about how they will balance next time ....being the balancer is hub centric ??

Don't worry about it.

This isn't a bad idea. I'd personally prefer to sand the hub vs the wheel. Just my opinion

I haven't had to do this in years, but if my memory serves me right, the entire bore of the wheel doesn't need to be sanded. Only a small portion, that is a small lip in the bore that gets in the way. I always used sand paper by hand and it only takes a few minutes per wheel.

Thanks for the help and advice guys!

Got the wheels on today, tried sanding by hand but ended up using a dremel... didn't have to take too much off.

Looks good. I've got those same wheels in 18x10.5 for my third gen progect. They may end up on my 97 until that is ready to come out of the garage though.

Edit: Need to lower that guy a couple inches.

it's amazing what a lowering a couple of inches does for the looks.
