Can I mount 205 tires on 7jx16 wheels?

[knabini]

the current rear tires are 225/50R16 on 7Jx16 wheels and they rub the fender lip (even rolled).
Can I mount 205/55R16 tires on the same rim (same size as the fronts)?
Thanks.

You sure can but I’m pretty sure they will still rub. My guess is you are running the wrong offset wheels so you will need to address that before you’ll stop the rubbing.

[knabini]

I don't know the offset.
These are the numbers from wheel:
911.361.020 44
as 1062 28139

[knabini]

I found this:
7 x 16 911 361 020 44 = 23.3 mm offset, backspace is 122m
Strange - one tire is fine and doesn't rub. Another - rubs.

[knabini]

I figured, if a tire's new width is gonna be 20mm less, that's 10mm on each side.
10mm will be enough to eliminate rubbing.
Right?

What model and year is your car

[knabini]

1987 924s. Wheels are from 911.

As I suspected your wheels are the wrong offset for the car. You need wheels with an offset in the 50’s not the 20’s, commonly these are called late offset wheels.

You can try 205 width tires but l like I said they may still rub. Reason is they will still inflate to fill the width of your wheel so just because they are 20mm thinner doesn’t mean they will give you 10mm more clearance either side.

As for left and right sides being different, well that’s quite common in hand assembled cars like ours.

Those are Fuchs "windmill" wheels. Never were designed for 924S automobiles.

Like 9FF says above, find some nice 52 mm offset wheels and they should fit just fine. Some nice design 90 wheels from a 944S2 or Carrera 2 should work.

Your car originally came with 195 tires, so 205 tires should not be a problem with the right offset wheels.

Something like these would fit perfectly and this style is the cheapest forged set of used factory wheels you can buy (no affiliation).

Thank you, guys, for you input.
I do like the fact that you answer fast and with proper explanations.

[dlearl]

Lots of great options for wheels, but yeah, they need to be the proper offset. D90's, CookieCutters, Club Sports, Cup I & II.





These guys usually have a good selection of used wheels.

I think those Club Sport wheels look great.



I've always been partial to body-colored Cookie Cutters, but I don think they ever made them in 16"-17"

Fuchs made wheels in 16" x 7"&8" for 944's. They just need a 951 prefix instead of a 911.

16x8 rear 951362117

You only need the 951 prefix if you plan on fitting them to a 951, otherwise there are 911 prefix that fit fine on an early 944na. The 951 prefix Fuchs had clearance on the inside to clear the Brembo brakes on the 1986 951, that’s the main difference. Regardless even 951 prefix Fuchs won’t fit the op’s 924S as they are not late offset wheels.

Something else just dawned on me, but I'm not up on 911 wheels. Wouldn't a 16x7 be a front wheel? IIRC, 924, 944, 968 wheels have different offsets F/R due to the transaxle, right.

Yes, 16x7 was the size of Fuchs wheel fitted to the front of the 1986 951, the rears were 8in wide. Even the Fuchs fitted to the early 944na were 7in front and 8in rear.

The F/R offsets are the same on every transaxle, they are either early or late offset.

[dlearl]

Understood, I meant the offset for a front 911 wheel would be way off for a 944 rear, correct? If I understood the OP correctly, he's got a 16x7 911 wheel in the rear of his car?

Ah ok, both front and rear wheel offsets were ET23 on the early 944, so the 16x7 front was the same offset as the 16x8 rear and all 16x7 Fuchs whether from a 911 or 951 were ET23.

[dlearl]

Gotcha. Thx. I think I've got info on late 944 vs 968 all mixed up.
