A bottle jack concentrates the lifting force in a small area, so I prefer a scissors jack or one of the lightweight racing jacks. Make sure that any jack that you use has enough reach for the older cars and using a block of wood to increase the range is not the best practice, the wood can crack under the strain or slip out of position. Some cars cannot use the axle as a jacking point to change a tire, the fender will not allow enough clearance to remove the tire unless the axle is free to drop. Examples are most of the 49-53 Fords and Mercurys, but some of the earlier cars will have the same problem. A scissors jack made for an SUV will usually provide enough lift at the frame. Check your frame for lifting points and if you are forgetful, mark them. I have a scissors jack that has two places for the handle, one for more torque and the other for speed. The one for speed is shaped to take a socket, so I use my impact wrench to operate it.

My 1948 Ford in 1956 had no jack in the trunk so I bought a bumper jack from Western-Auto. It served me well for 20 years though it looked bad for the bumper to torque up so high on one side. I worried if I had been taught poor technique as a one-year-old when my father took a long series of black and white photos that was preserved in an album. I go through the full range of operations to fix a flat tire including jacking up the car with a bumper jack. Later, with a truck it had a screw post jack that had to be placed under the rear axle or front suspension. Now that I am a member of the earlyfordv8club I have the 1941-48 Ford book which has in the section for "TOOLS" various bumper jacks. I specifically see the 51A-17080-A4 jack & base in fig. B-16 on page B-6 which has a trapezoidal post and the 8A-17080-A3 jack & base in fig B-19 on page B-7 as similar to the one I purchased so long ago and would definitely search for one to be accurate now. I can also assure you that the frame to the rear of the spring crossmember and the x-member is no where's near as strong as the frame forward of that place.

Do not under any circumstances use the antique bumper jacks as originally provided. They were dangerous then and are dangerous now, even more so with the weak non original replacement bumpers on many of our cars today.

I’m 85 years old and have a bad right shoulder so tire changing on the road is hard for me. I have towing coverage included in my Hagerty policy which includes my trailer and modern cars. I have used this twice in the last two years, once to flatbed a Model T about 10 miles to my house and once to change a tire on my modern car. I do carry a scissors jack in my antique cars though.
