Tire balancing needed
 

Do Model A tires need to be balanced? If so, What are the jacking points for the four wheels? I plan on using Discount Tire.

Re: Tire balancing needed
 

i never balance my wheels, never had a need to.. no shimmy at speed....

if you feel the need use dyna beads which some use.

model A wheels look like s--t with weights stuck on them..

good luck letting discount tire touch your wheels ...lol


jack up under the front axle and rear diff i have used all 4 corners and also just the centers.

put the stands under all 4 corners

Yes, they do.
Before you do you might want to consider the balancing beads.
I stopped balancing years ago on all my vehicles and use the microbeads.

I run 55-60 in my A all the time and the beads that happen to in those tires I picked up from Snyder ( http://www.snydersantiqueauto.com/5582).

I don't use their replacement valve though as I have sealing problems in the metal valve stems.

I would have them place weights on the inside of the rim if necessary. The tires are new and just came with the car. Were they balanced from the factory when new?

Re: Tire balancing needed
 

they dont look great on the inside either

Re: Tire balancing needed
 

I have never heard of balancing beads. Do they just roll around inside the tube and stay in play by centrifugal force?

Here's a Youtube demonstration of the Dynabeads like I use on most everything.

and here's the dynabead page that explains what is happening.

Do the beads that Snyder's sell work just as well as Dynabeads?

Re: Tire balancing needed
 

When you put tires on the rims it is advisable to make for best balance.

I set up a front spindle with light oiled bearings. I mounted the tire mounted on the hub clamped to a bench.

I then let the wheel find the heavy spot. I then broke the bead and rotated the tire until I got the slowest finding of the heavy spot.

Note: the colored dots on the tires have different meanings. Go look up what the colors mean. None of the dots lined up either way on my wheels when I got to best balance position.

I also spun the wheel with the tire to make sure the tire was true. Some lower cost tires I understand are not always very round.

How important is balance?
Not as much with the heavy axles (unsprung weight). The mass of the axles will dampen a lot of imbalance.

I happened to find with my 5 new Goodyear tires that one was closely balanced and another pretty good. The other two were ok. On each wheel I had spots where the imbalance in the tire and the wheel lined up and it spun much faster to the bottom.

It was a bit of work to do the balance, but it is sometimes better to work with what you have for a best fit.

I am a believer in balance beads and have a good supply in stock. My concern would be that all the beads I have seen say do not use inside inner tubes. What is the thoughs on that?

If you plan on driving at higher speeds then you should balance the wheels.

Re: Tire balancing needed
 

I made this tool to check for bent wheels and to check wheel/tire balance. I've never balanced my wheels and never had a problem, but have used the tool to check wheels before using them. The spindle, bearings, and hub with drum are good used parts, so I bolted the bottom of the spindle to the stand in case I need to use them on a car.

Just be sure they don't try to change a tire using one of their modern machines or you will have a problem with your rims being bent.

the latest quality modern machines will not harm the rims or the finish

Re: Tire balancing needed
 

Before going to the trouble and cost of balancing, have you driven the car?? Any shimmy, or odd feeling??

It does not shimmy. Driving one of these things is new to me with the big tires. My last car was a 62 Corvette with no PS or PB, and a 17" steering wheel. I just didn't know that most of the 31's really don't need their wheels balanced.

Re: Tire balancing needed
 

Yes

When I got Minerva, she had 6 month old Firestone Deluxe 19" tires. She was TOTALLY smooth from ZERO to 80 MPH, with NO balance weights! Gene must have put in Dyna-Beads!! I always forget to ask him.

How much should one buy for 5 tires?

Re: Tire balancing needed
 

Typically, for our tires, it's 4 Oz per tire.

I was low on dynabeads at the time so I just ordered from Snyder a 4 wheel kit and one extra. See link in post 3

(fwiw - DO NOT Drop any beads on the floor. I dropped a gallon jug of beads over a year ago and a few ounces got loose. I'm still sweeping them up!)
