Hey there, I would like to put s70 turbo rims on my 1985 244 gl. What do i have to do? Thanks!!

The bolt pattern is the same (5 x 108mm).

The backspacing of the rim is quite a bit different (i.e. the offset, or centerline of the rim, is deeper into the hub for FWD wheels.)

You need wheel spacers and longer studs, or wheel adapters that bolt over your existing studs.

Take a bare rim before you put a tire on it, and try it on your hubs, front and rear. You'll see what I mean. Backside clearance will be too tight, especially on the sides of the trunk box.

Now, pull the rim out about 3/4". See how little stud length is showing? That's why you'll need longer studs.

Do it right and be safe- don't home-brew something and risk having a wheel come off. These wheels can be used on RWD's, but the guys doing it have put some work into a proper solution.

By the way 240 wheel studs are NOT metric- they are 1/2"-20 fine thread.

Thank you very much! you have been very helpful. I have one more question. I did attempt to put the FWD rims on the back of my car and it bolted up and i do understand i need spacers but when i did so the car would not move. Can you by any chance explain that? Does it have to do with the pin that comes out and fits into a little hole in the stock rim? and do you know of any good places to get a wheel spacer with studs and or adapters? Thank you very much!!!

When you put FWD wheels on your RWD car, they were probably jammed against the frame of your car!

Check the inside of the tires for damage.

In the 240, the wheel clearance to the sides of the inner fenders (the trunk box) is very tight, even with proper RWD rims.

The wheels designed for the 740/940 fit ok, but any wider tires than stock will rub. Even the stock size of 205/55-16 on the Hydras will rub, but I run them all summer on my 240.

Thin wheel spacers can be used without long studs and push the wheels a bit further out so tires maybe 1 or 2 sizes bigger can be used - but that's about the limit.

I had a set of spacers that were less than 1/4" wide, made so they fit over the hub on the rear axle. That gave just that little extra bit of clearance needed to prevent rubbing.

Using the FWD rims, a spacer or wheel adapter is required. I don't have any info on companies selling them, sorry.

That little pin is of no real consequence. On my '93 I swap all four wheels (and mounted snows) each winter, and because my "snow rims" are older and don't have the requisite holes simply unscrew the pins (10mm wrench) for the winter and put them back in the spring for my summer-only tires and wheels.
The pin is a redundancy, the only thing it does is keeps the rotor on the hub -- it sounds important but actually, the caliper and its pads are doing the exact same thing, as do the wheels themselves when they're also bolted on.

That said, there's no way that the pin would keep the wheel from turning. The wheel itself must have been jammed against some stationary part (e.g., the caliper) when you bolted it on the car. It might have "looked" straight, but it just has to be firmly touching anything to keep it jammed in place.

The alignment wheel rim to hub pin is of consequence if you spin balance the wheel on the hub.

I forget the other reason why it's there. That pin serves a purpose. Else I forget.

I think that's the original reason for it -- Volvo spin balances the tire/wheels *on-the-car* at the factory, and being mounted at the time, it also includes the balance of the heavy brake rotor during the process. Thus, the pin ensures that the wheel is mounted the same way if it's ever demounted.

The other reason that you're trying to remember, perhaps, is to fasten the rotor to the hub -- the same purpose as the ordinary 10mm bolt in the other cars.

However, when do you take off a wheel? When you rotate your tires, or to put on a set of snow tires. At these times, assuming you're not spin-balancing the wheel/tire on-the-car, the pin's position-keeping role is utterly useless.

I always insist on spin-balancing, in fact I pay extra money for the Hunter Road Force system which balances the tires with a roller pressing against the tread of the tire to take into consideration tire distortion (and I get a printout of the results). However, it's been decades since I've since any shop that can do a spin-balancing of any kind while the tire is mounted on the car -- which makes the function of the pin a moot issue.
