The narrowing made my car feel finicky during turns, so would 7mm spacers help? Would it just lead it back to stock load onto bearings? or would 7mm be too much and load the bearings leading to early bearing failure? ... well early as in 190k worth of wheel bearing early.. Haha
The smaller wheel offset number would stress the bearing more than that +55. Installing a 7mm spacer just places the wheel back to the stock +48. It's not going to place any more stress on the wheel bearing than the stock wheel without a spacer.

One thing to keep in mind. The wheels bearings are known to fail, even with the stock offset wheels!

I seem to recall that there's a maximum spacer thickness, before it's advisable to install longer studs?

I think it's 3mm on oem length studs.


The higher, the fewer.

@subaru3169 looking at discussion on this thread: Wheel spacers? It appears 3mm is acceptable. Some say 5mm is doable, but others say no. No way you could run 7mm spacers without longer studs.

sweet thanks.
how would smaller offset increase wheel bearing stress? I was thinking less due to the leverage arm shortening. just wondering the mechanics.

7mm is a lot..

@frijoles the stock offset is +48. A larger offset number moves the tire/wheel inward towards the suspension... like that +55 offset. A smaller offset number, like +40, +42... what we have on our Foresters, moves the tire/wheel outward towards the fender. This will put more stress on the wheel bearings, which are know to fail even at the stock offset.

As to the +55 offset with a 7mm spacer. you will need to install longer studs to get enough threads for the lug nuts.

Thanks in advance!

Okay, so yes, I can CONFIRM that the '13 WRX 17X8 +53 DO need spacers when running a 235/45 tire IN THE REAR ONLY, I ordered 3mm hoping that would be enough and am going to give that a shot today or tomorrow.

I had no fitment issues in the front, but the back rubbed right away.

Hey guys.. Wanted to add to this post since I did use it to find out what other factory wheels will fit my sister's 2002 forester.

But I couldn't really find if the 2018/2019 Crosstrek premium wheels fit or not..

She originally had 15x6.5 (+45ish?) Subaru HUBCAPS with 205/70/15.. Beat tires and just ugly.

And the Crosstrek wheels/tires are 18x7.5 +55 with 225/55/18.. I took a chance if they would fit or not and just purchased from someone locally..

But luckily.. They fit.. No spacers.. Only thing I needed to do was shave off a tiny edge of the front lower control arm bushing bracket with an angle grinder.

The tears were very very close.. Within a credit card clearance!..but it is a static part that came that close.. So if it doesn't touch.. It won't.

I tested it out by driving up to ~75mph..doing fast circles.. Hitting bumps..reverse etc..

I will probably get some decent spacers for the rear to make them sit flush.. But these were pretty much bolt on! Cleared everything Lock-to-Lock. Very close.. But it all works out perfectly.

Honestly.. I thought they were pretty ugly at first.. But once they were mounted on the car.. They look to be aftermarket wheels and look great!

Wanted as much sidewall as possible.. And yes the OD is slightly larger with the new setup.. And making the speedo read about 3mph slower.. But it's fine

So..

Vehicle: 2002 Forester

Wheels are from :
2018/2019 Subaru Crosstrek Premium
Wheel:18x7.5
Offset: +55
Hub and bore: 5x100, 56.1mm bore
Tires: 225/55/18 Falken Zeix.

Modifications required:
-Slight trim on lower control arm bracket edge.. Basically just chamfer off the sharp corner.. It does not effect anything structural or safety wise.

Other than that.. Bolt ON.

hopefully I can get these pics uploaded

Hope this can help someone else.

Not sure if it was posted but here's the 2018 Crosstrek wheels on my SJ. Straight takeoffs so the tires are 225/60/17
