Planning to purchase two new Goodyear 4.50 X 21 BW tires. Does anyone in the North East Ohio area mount and/or sell these tires?
Thank you

I thought Lucas had an Ohio location, but their website doesn't show it. Try a Google search.

The 4.50 x 21 tires were used on the later Model Ts and the 1928-29 Model A Fords. Those are regular non-clincher tires and should be easy to mount. If you are putting them on the 21 inch Ford supplied welded wire spoke wheel or the 1928-29 Model A Ford welded wire spoked wheel running adapters on your speedster -- they mount like any other modern drop center tire.

You might even be able to order them through the local Goodyear dealer in your town. Any tire shop should be able to mount them for you on the wire spoke wheel that is a drop center design. If you are putting them on the wood spoke wheels -- I would be sure to find someone who is familiar with mounting them as you can warp the rims if you are not knowledgeable or careful.

Snyder's Antique Auto Parts, Inc. is there in New Springfield, OH 44443 and they are one of the largest old car suppliers. Also contact the local club -- see: and

They probably could recommend someone. And even better they could show you how easy it is to change them. As a 15 year old little kid (I was small for my age) I could barely change a clincher tire but the 21 inch drop center rim tires were much easy to do.

I noticed also this is your 4th posting. Welcome to the forum! And if you haven't read some of the Model T safety information -- please take a look below:

There are some known safety items about the Model T that you should check out before you start driving it. (If you are driving slowly on a farm where it doesn’t matter if the brakes fail, the spokes fail, car turns over, etc. – then you can ignore them all). If you have been around Model Ts for while you probably already know about the pitfalls. But if not, I would recommend you review them so you learn about those issues second hand rather than first hand experience. Getting an experienced Model T person to help you learn about your car can save you lots of frustration and possible expense. For example if you fail to retard the spark and you push down on the starting crank at the front of the car to start the car, you could easily break your arm. That is a known safety issue with Model Ts. And it isn't dangerous as long as you understand what causes it [spark lever advanced [that is the left hand lever on a left hand drive car] it should be pushed up], commutator adjustment rod installed wrong or bent improperly so that even with the spark lever up, the spark is still too far advanced, shorted wire on the commutator, etc. . And if you use the electrical starter that your car should have – if the spark is advanced and the engine back fires – it can damage the starter and/or bendix drive. For additional details please see:
and there are other related threads.

Some other safety related items:

And be sure the car is in safe working order. An engine that burns oil is not a critical safety issue (at least not in my book) but the front end castor if it is set up negative can flip the car. If the rear axle still has the original babbit thrust washers you can lose your normal service brake. Those and similar items are well documented "oops" for the T. But if you have never been around one -- they are probably new "data points" for you. Some of them are listed below – not to scare you but to let you learn from others rather than discovering all the lessons on your own.

Safety Glass is nice:

Use safety wire and not lock washers or cotter pins on the two studs holding the wishbone to the underside of the engine.

Lots of safety items

Over center steering – shouldn’t happen on the later Ts (yours is a later T)– but if someone replaced your later teens steering gear housing or rebuilt it without the lock pin – or installed the wrong length drag link it might happen: as well as:

Types of safety wire:

Example of loss of brakes caused by drive shaft failure:

Top T tips – many of them are safety related also:

Tour safety check list:

And if you have a gas hot water heater in the garage – be very very careful. The float in a Model T Carb will sometimes stick (or trash in the valve) and the carb will leak gasoline. Not too bad if there are no sparks – several homes, garages and cars have been lost when a gas hot water heater was near by and someone started the dishwasher other item that caused it to turn on the burner at the wrong time. Note gas fumes tend to be heavier than regular air …. so they tend to hug the floor. If you adjust your garage door to let the mice in and the air out – that is a temp work around. But replacing the gas fired hot water heater with an electric heater or having the gas one relocated away from the garage is the best thing

Even with a perfectly good and properly adjusted front steering system – if you back up quickly, the front wheels can go full left or full right and pull the steering wheel out of your hand – so remember to back up slowly. It is caused by the caster of the front wheels similar to the casters on the front of the shopping cart – designed to be stable in one direction but not so stable in the opposite direction. Since you have already been driving the car you probably do not have the following problem – but you might still want to check. If someone rebuilt the front axle and it is was really difficult to keep the car going straight they may have inadvertently swapped the front spring perches. There is a left and a right spring perch that tilts the axle so the bottom of the axle is slightly ahead of the top of the axle (5 1/2 degrees positive caster – although there is some discussion that it is a little less but still positive for the balloon tires like you have). If it has negative to neutral caster it can cause a wild ride and also could cause the car to flip even at a slow speed see: that shows the spring perch installed incorrectly and how the front axle looks then. Also see: Note even with the spring perch installed correctly a bent or shortened wishbone could cause neutral to negative caster.

Also the rear axle thrust bearings if they are babbitt (originally bronze in the 1909-1915 cars and then switched to babbitt on the cars during 1915 ref: see part number 2528 ) can fail with minimal warning leaving the driver without the normal transmission brake (the main regular brake on a stock Model T). See the discussion at: If you loose the brakes and you are on a flat area with minimal traffic – it is not nearly as bad as loosing them while going down hill towards a busy intersection. See the rear axle babbitt discussion part way down in the following thread:

Wood spokes work fine – but they need to fit tightly, not be split or wood rotted, made of quality wood (pine is not a good choice and yes some folks have offered pine spokes for sale) and the bolts etc. need to be tight without too much wobble in the wheel. see:

Again a T is a faithful servant but it has some known issues that the driver needs to be aware of and to take proper precautions about.

I would also encourage you to check out the local Model T Ford club(s) near you. As mentioned above please see: and They can be a real source of encouragement and help you as you learn to maintain the car. Steve Jelf has an excellent set of books he recommends for new owners on his web site at: with the T section at: and the recommended books listed at: Note there are also free “how to books” on the internet such – see: 56bbT2W68C&hl=en&sa=X&ei=tdpWVMi4PMOjgwSAhoC4Ag&ved=0CBcQ6AEwAA#v=onepage&q&f=fa lse and there are others – but I didn’t see a 1926-27 one. And the Ford Service is online at: and does include the 1926 -27 “Improved car” features.

Good luck with your speedster and welcome to the forum.

Respectfully submitted,

The 4.50 X 21 tires are easy to mount. Definitely doable by the average T guy.
