The dot is to mark the heavy spot, so it is usually placed across from the valve stem. However, the valve stem weighs so little that it doesn't really matter. They should balance up pretty well no matter where the dot actually ends up. The important thing is that your mounting shop doesn't hurt the rims or locking rings. The rest is easy.

Wrap the wheel edges in a heavy, black trash bag and the tire should slide right on. I always change my 1931 Dodge tires while the wheel is on the car. Makes it MUCH easier than wrestling with it on the ground. My wheels are like yours....

Never bothered with the dot you mentioned. I index all the tires to match the valve stem and company logo and do the same with the hub cap, all four and the spare match. Bob

I deflate the tire, shove the plastic bag in and around the wheel bead edge. I use a rounded tire spoon with no sharp edges and slowly work it around the rim and pulling the tire off. I never get chips in the paint that way. You may want to check on the backside of a wheel to see how hard the paint is prior to mounting the tires.

I usually fold the trash bag a few times in order to cover the rim well. You could use a few layers of painter's tape instead of the bag.

Put the bag on the wheel edge, put the tube in the tire and be sure you have the rim band/tube protector on the wheel prior to installing the tire/tube as a unit. Put the first bead on, pull the trash bag off of the rim and insert it back on to put the other tire bead on. Then you can line up the valve stem with the hole if you haven't already done so.

Sometimes, soapy water will work to help slide the tire on if it seems to be too tight.

That works very well, but you may have to paint them again after mounting the tires using that method....like he did.

Put the tire on the wheel from the back side, I use a rubber hammer, never tire irons, irons are for removal. I like a shipping blanket on the floor and a cable or chain valve stem pulling tool. Tube in the tire, inflate then remove the core and install tire & tube. Once you are on a roll all four should take you two hours. Bob

29-31 Pontiac operators manual says to mount tires this way on drop center wheels.  I have always put the valve stem opposite the serial number.  Out of 9 sets of tires only one set needed one tire balanced.

As 1937hd45 said....find a soft surface if you mount them on a floor.

Another use for the trash bags (Like Hefty) . If you are doing a wheel alignment on a level steel or concrete surface and do not have the spring/roller plates to do the Caster 20 degree swings you can cut up into 1 foot squares the trash bags. Five or six 1 ft. squares under each front wheel will allow a perfect swing from zero to 20 degrees and back through zero and 20 degrees  to check and adjust the Caster adjustment angle. They will also allow the suspension to be jounced to level things out after a car has been jacked off the ground.

On cars with a high profile tires 60 series and above if you leave the tires in the sun for a while then spray silicone on both beads of the tire and around the edge of the rim you can sometimes mount a tire by hand. This is easily accomplished on the tire mounting/dismounting machine using your body weight and a good pair of strong arms. 75 series tires are really easy to do this way.

how do you use hammer       going to have to pry the tire over lip ?????

Just smack the tire bead that isn't were it should be with the rubber hammer, no danger of chipping paint.

I was taught to put the dot next to the valve stem.

 

Shampoo is a great lubricant for mounting tires. Don't use your wife's $45 stuff you will get in trouble. Get some from the dollar store for a $1 buck.

Make sure you have a gutter strip down in your drop center and I always Johnson's Baby Power the tire casing and the tube. For the tube, just put some baby powder down in a glad bag and drop tube in and shake.  They do make tire talc, but it is a little hard to find.
