Small Garage
Turning a Car in a Space That Will Not Let You
Wheel dollies move a car sideways when the geometry says no. What they can carry, the surface they need, and the version of this that is genuinely unsafe.
Contents
A wheel dolly puts each road wheel on a small castor platform, so the car can be pushed sideways. That turns a car which physically cannot be steered out of a garage into one you can walk around by hand.
Two conditions decide whether this works: a smooth level concrete floor, and getting the car on and off safely — which is an ordinary jacking job and deserves the ordinary care.
A note on this guide: this rests on how the equipment carries and moves load and on manufacturers' stated capacities and surface requirements, not on cars moved here. Lifting points are specific to your car; the handbook is the authority. See how we test.
The problem, as it appears
A garage that the car fits into and cannot be worked in. A driveway where the car has to be reversed onto a road you would rather not reverse onto. A second car that has to come out first, every time.
Or the classic: the car is in, the doors will not open far enough to get out, and moving it thirty centimetres sideways would fix everything — getting in and out when doors barely open.
Why the obvious answers disappoint
Steering it is what you have already tried. A garage narrower than the car's turning circle does not care how many shuffles you make.
Pushing it moves it along its own axis and nowhere else. The wheels point where they point.
A skate under one corner is the improvisation, and it is the one to avoid. A single dolly under a loaded corner with three wheels on the ground puts the car in a state where it can move in one direction under a push and not in another, and the geometry that results is not something you can predict while leaning on a wing.

What actually matters
1. The floor, which decides whether this works at all
Small castors need a genuinely flat, hard, smooth surface. Concrete in good condition is the case they are designed for.
What defeats them: expansion joints, drain channels, cables, gravel, a slope, and a soft patch of tarmac in summer. Each of those stops one wheel while the others keep going, and a car pivoting on three castors is not a controlled situation.
Walk the route first. The whole route, including where you intend to leave it.
2. Capacity, per dolly rather than per set
Weight is not distributed evenly — the engine end carries considerably more than a quarter of the car. Check the rating for a single dolly and leave margin above what that corner actually weighs.
Wheel dolly set
Check the rating per dolly rather than for the set, and measure your wheel width against the platform. The engine end carries far more than a quarter of the car.

3. Getting it on and off, which is the part with the risk
This is a jacking job. One corner at a time, manufacturer's lifting points, stands taking the weight rather than the jack, and chocks on the wheels still on the ground.
Then lower onto the dolly — deliberately, because you are lowering a corner of a car onto something designed to roll.
Rubber wheel chocks
On whatever is still on the ground. A car with two corners on castors has considerably less resisting a push than a car on four tyres.

The full argument about what holds a car up and what merely lifts it is in trolley jack vs ramps vs axle stands.
4. Knowing where it will stop
A car on castors does not resist a knock. Decide where it is going before it moves, keep the route clear, and put it back on its wheels or on stands rather than leaving it parked on castors for a week.
The options, and who each suits
Four dollies if the manoeuvre is genuinely impossible otherwise and the floor is good. This is the tool for the job and there is no substitute.
Two dollies, on the driven axle only, if you need to swing the back end round a little and the front can steer. Cheaper, less capable, and the same rules apply.
Neither if the floor is uneven, sloped, or outdoors. This is the honest limit of the technique and no amount of care compensates for a surface that stops one castor.
Parking differently if the problem repeats. The dolly solves an event; changing the approach solves the situation — parking in the same spot every time is about making that repeatable, and working on a car in a garage too small covers the wider version.
The mistake to avoid
Using one dolly and pushing. It is the improvisation everyone tries and it produces a car that moves in a direction decided by the three wheels still on the ground. Either all four, or an axle pair, or none.
The second mistake is treating the lift as trivial because the car is only going up a few centimetres. The height does not change the rules — stands take the weight, chocks go on, and the jack is not a support. Lowering a car onto castors is the one lift where the thing you are lowering onto is deliberately free to move.
