I am going to need tires for it and can use some advice for brand , price, size and anything else you can think of.
#1. Stay under 50 MPH with them
#2. They look like 30X3 1/2
#3. Here's a link to some good folks:
When I measure the diameter it they measure 21". Am I not understanding something? All of the references to tires for a 1914 appear to be 31's.
A 1914 had non demountable wheels, 30x3" in the front and 30x3-1/2" in the rear. Someone has installed more modern demountable wheels on your car and from the bent out edge on the rims it looks like '25-'27 balloon wheels that uses 21x4.50 tires.
From Burbank you have about an hours drive in a modern car to Chaffin's garage in Corona - they can help you with anything you may need for your Ford and will give good free advice too
Frank,Before you make a large investment in tires,tubes,and flaps i would have a expert look over your wheels,spokes,and rims.As per what Roger said,are you going to try and use those or maybe you want to go correct? One thing sure,never never leave your new tubes in the box!! Bud in Wheeler,Mi.
Bud is correct on never leave the tubes in the box. If you leave the tubes in the box for an extended period of time, they will crack where the tube is folded. Take them out of the box and put enough air in them to give them shape - it only takes a few pounds of pressure.
Whether you stick with those wheels or decide to go "correct", there are several good sources for new tires. Your closest would be Lucas Classic Tires in North Long Beach.
I second what Roger said about Chaffin's. Glen and Dave are very helpful guys and will have most of what you need.
If the out side of the rim measures about 24" then it is a 30X 3 or 30X3 1/2 If the out side of the rim measures about 22" it will be a 450-475 21. I think the 30" measurement is aprox out side dimension and the 3 or 3 1/2 will be the width and with the 21" they use the bead size and 4.5" to 4.75" added radius height. Hope this helps
Actually a 30 X 3 1/2 rim measures 23".
Rim measurements are from the inside of the tire bead where it contacts the rim, not the outside of the rim. Dave
Is 30 the overall meaurement of the tire?
Yes, that's the old style of naming a tire - giving the approximate outer diameter. Used mostly on clincher tires that didn't have steel wires in the bead, so the inner diameter at the rim could be stretched somewhat. Though it has been used for bicycle tires also and they usually have wire beads.
So the 21-4.50" balloon tires has about the same outer diameter - the math is: 21" rim plus two times the tire height 4.50" is 30" outer diameter. For clinchers you take two times the tire height from the outer diameter, that'll give the rim diameter => 30 - (2x3.50) = 23" (24" rim for 30x3").
