Tire Shops Good with Wide-5's in NorCal?

#1 Post by Randy Nonnenberg » Tue May 27, 2008 5:35 pm

356 Friends,

I am planning to mount my new tires on my restored original 4.5" wheels in the next couple weeks. Has anybody found a shop in the bay area that will mount/balance these vintage wheels/tires with the proper care?

Also, do you guys have metal weights on the outside of your wheels, or is that best avoided nowadays?

Thanks,
Randy

Randy, I live in San Mateo and the only tire store I've found in my
area that has the correct adaptor to mount and balance 356 wheels is
this one:

http://www.fivepointstire.com/
Five Points Tire Imports
2115 El Camino Real
Redwood City, CA 94063
(650) 365-0280

I always have them put the balance weights on the inside of the
wheel. I am not aware of any compelling reason to have them on the
outside.

I also request that they hand tighten the lug nuts to 90 ft. lbs.,
and they oblige. If you don't ask, they'll use the air gun and
probably over-torque them.

ABLE Tire in Novato mounted tires for me on my 5 1/2" Mangels last year. They also mounted tires on my 4 1/2" original 356C wheels two years ago.
All the tires came from the Tire Rack.

My local shop does a lot of special type of mounting, their machine
has a rigid mounting arm that does not touch the rim. To do a perfect
balance you sometimes need to mount weights both outside and inside. The
wheel can be out of balance both in the outer plane and inner plane. You
can compromise by placing the weights in the inner plane near the
centerline. The 356 is not to fussy about the balance but I would at
least mount the wheels with the least amount of weight on the front.

Another route to go would be to buy your own adapter. That way you can take your wheels to any tire shop. The only one I've seen for sale is offered by Mainly by Design. The website has them listed at $69.95.

They are a Registry supporter.

Here's their website:

least mount the wheels with the least amount of weight on the front.
Before all the fancy electronic machines for balancing, circa 1953, I worked at a repair facility that used Behr alignment and balancing equipment. The owner instructed me in the use of the balancing machine and noted that it ..."takes 3 weights to do a proper balance. One static weight and two weights for the dynamic [then called "spin balancing"] balance."

He also pointed out that the most important weight was the static weight [as this would take care of the wheel tramp] and if you had to use more than 2 oz of weight diagonally opposed[ one 2 oz weight on the inside, one 2 oz weight on the outside], the tire was not any good.

With simple logic you could balance a tire with a minimum of weight but it often required several spins[they barely spin it once with the machines today {and only in one plane}] and the movement of the static weight to the opposite side originally placed. This was important to the customer then because he was charged for the service and the weights used. When finished, you mounted the new/used tire with the most weight on the axle with the most weight. For American cars then, this was the front because of improved damping.

The tolerance class for motor car wheels, rims is G40 according to research by the German Association of Engineeers[VDI] At about 100 mph the residual imbalance at the radius of compensation [where you place the balance weight] is approximately 10 oz-in/lb x E-3. So lighter wheels need closer weight choices or trimmed to specification.

I am not certain about the comment that the 356 is not fussy about balance. If you drive fast, balance is important.

How about a good, knowledgeable tire shop in Fairfield County, CT?

Steve,
Folks are going to miss your question, since it's buried under a subject line for the other end of the country.
I'd start a new subject if you want info on CT.

I was having the same problem, so I bought the wheel adapter from Mainly Custom and took it to the regular tire place up the street.

I still change my tires by hand. Always have. Takes me all of 5 minutes. The nearest “city” is a half hour away. Do the math.

John,
How do you balance them?

I don’t bother to balance the wheels. Every now and then I’ll take one of my jalopys out on the freeway, I never seem to notice any vibration or wobble. When I was a kid my uncle owned a tire shop. He told me that the lead weights were more to get money out of people than to balance the wheels. I believe him. However, if you’re gonna race your 356 at triple digit speeds, that would be different.

For those who do balance the 205mm B/C wheels, that adapter is still available:
