Datsun 1200 uses a common wheel bolt-pattern: 4 bolt holes on 4-1/2 inch circle (aka 4-on-4.5). Nissan engineers specified this in inches. In metric this is equivalent to a 4 x 114.3 PCD (Pitch Circle Diameter). Stock Datsun 1200 wheels are 12 inch diameter, 4J (4 inches wide). All models, even GX models and 1994 Sunny Truck models, used 12" wheels. Only the Datsun 1200 SSS used a special wheel, though still 12" diameter. Wheels up to 18x7 will fit under the stock bodywork.
Stock Datsun 1200 wheels are 12Jx4. This includes GX models.

NOTE: North American B210 1976-1978 large-brake wheels are 13" but have 4mm extra diameter inside, possibly for clearance of the large brakes. These wheels are same as Datsun 610 and can be identified by six thin slots on the face.

The stock wheel is 30 mm positive offset (mounting face is 30mm outboard of the wheel's center line). This offset perfectly centers the tire inside the wheel well.
Because the stock wheel is 4" wide, it can fit the stock 155-width tire or a wider 165-width tire. Any wider tire, such as 175-width, requires a 5" wide wheel.
STOCK = 30 mm offset

Too much scrub makes the car a bit unstable under braking and therefore won't generate quite as much cornering grip. This applies mostly to the front suspension (due to the kingpin inclination angle) and not so much to the rear (where camber is nominally zero due to the live-axle design).
This means spacing your wheels outward (away from the strut) is generally bad, increasing your scrub radius. Using negative offset wheels, wheel spacers, or longer LCA or longer ball joints will exacerbate this problem.
McPherson struts have a scrub radius problem in general. However, since Porsche 911 and most BMWs use McPherson strut, it is not necessarily a serious handling problem which cannot be overcome. Newer modifed-strut designs (such as 2011 GM HiPer Strut and 2011 Ford RevoKnuckle designs) reduce the scrub radius. For your old car, keep the scrub radius to the minimum.
scrub radius. its the distance from the centre of the tyre contact patch to where SAI intersects the ground.
'+' scrub radius where the centre of tyre contact patch is outside SAI, '-' where its inside the SAI.
SAI = Steering Axis Inclination. On a strut front end, its simply an imaginary line drawn throught the centre of the strut. Or, it you have bent struts, it's a line drawn through the lower pivot (balljoint) and the top 'pivot' (where the shock insert bolts to the strut top)
Strut front ends apparently don't like lots of + scrub.
Obviously with a given wheel offset, the only way to alter scrub is to alter the SAI. Movint the top of the strut inwards will do that, but also move the centre of tyre contact patch outwards to a lesser extent, so you can't really alter it all that much.
anyway, all i really know is my +3 offset (103mm backspace) 7" Hotwires work much better than the -10 (90mm backspace) offset 7" superlites I had. Would other less offset wheels work better? I dunno...

Largest Sizes to Fit 1200
17-inch diameter wheels easily fit the 1200. The key is: width of the tyre and overall height of the tyre. Even 18" wheels are being used on 1200s with stock bodywork, if a skinny low-profile tire is used.
The wheel mainly positions the tire within the wheelwell. The tire is the part that will rub on the fender or rub on the spring. So the tire size is more important than the wheel size.
To make maximum use of the wheelwell width:
- Front: 3.25" is the maximum backspace (which is used by the stock 4" wheel). So if going wider, the Offset must be reduced from +30.
- Rear: +30 Offset works best with Datsun 1200, allowing the largest width tyres (205-width tyres).
You can fit even wider tires by shifting them out of the fender opening. A zero offset wheel will do this with anything larger than 165-wide tires. The tires will rub on the bodywork unless they are very low profile (small diameter, such as 205/50R13). But usually Rolling the Guard and/or overfender flares are utilized.
- 4": B110 12" stockers are 4" wide with +30 offset
- 4.5": B310 13" +30 stockers won't fit the front of the 1200. They hit the brake calipers, which may be related to the shape of the wheel.
- 5.5": Most with appropriate offset will fit a Datsun 1200. 15mm offset wheels fit nicely under the front guards, but look anemic on the rear.
- 6-inch wide wheels: most will not fit, but a zero offset will.
- 6.5": the biggest 15s you can put on are +24 15x6.5 even then they stick out a couple of mm past the fenders
- 6.5" 16s with a 40mm offset (silvia wheels or R32 skyline stock rims fit this). These wheels are the limit, I have 195/45 R16 on it and they sit within the guard and don't rub anything....but the front of the guard has been altered.
- 7" Reportedly 13x7 +0 fits perfectly
- 7" wide wheels with offset of +10 require front guards modification (they will rub on the fenders). At full lock -- depending on the tires -- the fronts will probably scrub inside the guards
- 7" 14s with 0 offset sit flush with the rear and poke a little on the front. More positive offset bring them inside, but then you risk hitting the struts
- 7": 15s +10 offset on fronts and +2 offset on rears. Tires rub a little at full lock. With pumped guards with possibly 15x7 -2 offset would work better.
- 7": I have 14x7 on my 1200. With zero offset. It is a tight fit with stretched tires. Mine have 175/60R14 tires, so obviously they are stretched over the 7 inch wide rim.
See: Tire Sizes for a discussion of the largest tires that will fit and which wheels are needed for those tires.
IMPORTANT Height has little to do with your wheel, but more to do with the tire. See Tires a 195-width tire will fit if small enough diameter (e.g. 195-50R15) You may need to roll the fender.
Rear wheel mounting flanges in Datsun 1200 reportedly can vary by 10mm side to side (see offset diff housing alignment problem?).
- 7": 13x7 with 0 offset and they fill the gaurds perfectly. The tire will be under the guard lip, and will rub if the 1200 is lowered unless the tires are very small diameter.
- 8.5": 13" -15 with 175/60R13
- 9": 13 x 9 zero offset, tire 215/50r13
There is more room under the rear of the Datsun 1200 pickup model, compared to the sedans, wagons and coupes. However, the leaf springs are the same relative location, so practical limits are the same as coupe, sedan and wagon.
Stock Datsun 1200 Wheels (12 x 4) weigh 11 pounds each. Virtually all aftermarket alloy wheels are heavier, except for very expensive magnesium wheels.
See main article: Wheel Weights
Wheel adapters can be used. These bolt to the hub, then you can fit other wheels. For example, fitting 5-bolt wheels to the stock 4-bolt hubs.
If the offset of your wheels is too positive, you can use spacers to space them out to the proper place. You may need to fit longer wheel studs.
See main article: Wheel Spacers
If the wheel offset is too negative, they will fit the fenders (guards) and there is nothing you can do except cut out the bodywork, perhaps fitting large flares.
Modifying Axles to fit other wheel patterns
Modifying Axles to fit other wheel patterns can be done as well. For example, you might have the axles drilled to fit five bolts, enabling you to use 5-bolt wheels.
Any wheel that is 4-bolt on 4.5 inch circle (114.3 mm PCD) and 71mm center hole fits will bolt onto the Datsun 1200, depending on the offset. Fitment also includes the tire sizes, as taller tires may hit the bodywork.
NOTE: The offset on most front-wheel drive wheels is too much.
Wheels that fit can be sourced from these vehicles:
- Rear-wheel drive Toyota
- 1960s Ford Falcon and Mustang 4-lug (6-cylinder models)
- Chevrolet Corvair (5 x 13)
- pefect for the rear
- may need a 1/4 inch spacer on fronts to clear the brake caliper
- Rear-wheel drive Datsun & Nissan models.
- Datsun B310 wheels fit the rear, but do not fit the front of Datsun 1200
- Datsun 240Z wheels -- 14"
- Uni-lug alloy wheels
- Rear-wheel-drive Mitsubishi
- Skyline R31 spare steel wheels (14")
Nearly any rwd 4-lug on 4.5 inch bolt centers fit. These are equivalent to "114.3 PCD" in metric conversion terms.
