I'm wanting to put redline tires, size 215/75/15 on Magnum 500 wheels 15x6. Do ya'll think will have any scrubbing problems? My springs seem to stand up like they should. Thanks Tom

If your coil springs are ok, then you'll have no problems. My '70 Avanti has Magnum 500 wheels and P215/70R15 redline tires and it has no clearance issues...then I did have to replace the coil springs as they had those little twist in spacers in the springs when I purchased the car. The 75 series tires like you mentioned aren't as wide as what I have, so you should have even less potential clearance issue.

Check with SDCer Peter Sant, who runs his maroon 1963 R2 Avanti at The Pure Stock Drags with Magnum 500 wheels...and if I am not mistaken, tires even larger than those you cite, Buck. BP

Gunslinger, I saw your picture on that car show site. Where di that little spoiler on the front of yours come from? Also, what center caps ar on your wheels? It sure looks nice.

I agree with Bruce. My 74 that I purchased has 235's on it with Magnum 500's and no sign of damage anywhere. I can't get to mine easily but I'd ask Bruce or Bob P's contact about backspacing to be sure you are all discussing the same setup.

The only possible issue with 15x6 Magnums is that if you have Turner brakes they may not clear the calipers. The four I have from a '70 Avanti won'y work on my '64 with Turner brakes, but Gunslinger also has '70 Magnums and two of his do clear the Turner brakes (?). Part of the caliper can be ground off, but I was kind of afraid to try it. I do have 215x75x15 tires on my Magnums and I have them on my disc brake Wagonaire with no issues.
On the '64 Avanti I had before I was running 225x75x15s on 6 1/2 inch Mopar wheels. Only on hitting a bump while making a hard turn did I have any clearance problems and it sat way too low in front.

The air deflector is from Saturn...part #21031161 from a GM dealer. You bolt it to the radiator support under the front end. In my case, it dropped engine temps at highway speeds about ten degrees or more by redirecting air up into the radiator rather than passing under the car creating turbulence. It's an easy modification. I used some aluminum bar stock to reinforce it but some don't bother with that.

The center caps are the normal caps for a Magnum 500...I simply added the round stick-on Avanti emblem available from Studebaker International and other vendors. I considered using the 3-blade knock off style caps available for them but the more I thought about it the more it seems I would be losing the elegant simplicity of the Avanti design...less is more. If they added function it would have been fine, but they don't. It seemed they would detract from the visual look of what I wanted.

When it was discovered that two of the 500's on my car scraped the calipers the Turner kit comes with, we found that two of the rims have about a 3/8" different offset than the other two, so I leave the two on the front that clear the calipers. Since my car came with the 500's from the factory, I can only guess the wheel manufacturer sent Avanti Motors rims from more than one production run with slightly different dimensions. As long as they fit and cleared the Bendix calipers without problem, Avanti Motors had no reason to second guess anything. It wasn't until years later when owners started installing the Turner kit that problems began cropping up.

The reproduction Magnum 500 on the market by Wheel Vintiques may or may not clear the Turner kit without some grinding of the calipers...I have no idea of their offsets or how closely they do or don't follow the original patterns.

Not exactly. 215mm is the section width on either tire. It is the height which differs: 75-series is 75% of 215mm, or 161.25mm tall. The 70-series is 70% of 215mm, or 150.5mm tall.

FWIW, the height of the tires is as pertinent as the width, as it is the top of the tire which often gets into the top of the front fender opening.

I run 205x75x15 on Magnum rims for my 64 Avanti with no rubbing issues.

I believe the aerodynamic effect of the spoiler is to create a low pressure area behind the radiator to cause greater air flow through the core. The 10 deg temp drop is real.

I looked at Wheel Vintiques site and they had several types of lug nuts. Does Avanti have some odd lugs?

i also used the same saturn part# 21031161 on my '63 with the same good results on temp drop. :) very easy to install...

I am running 215 X 70 X 15 Magnum 500's on my 63 Avanti. I have Michelin X One tires. The rims are also 7" wide. I had to put a 3/16" spacer on each hub to clear the Turner Brakes.
The rims came from an aftermarket Mustang parts dealer in PA.
I put the Avanti decal over the top of the Mustang emblems.

Peter,

Can you give us the name of the PA Mustang parts guy that you purchased the set of 15 inch Magnum 500 rims from? What was the cost? Did your purchase include the chrome (I hope) Mustang lug nuts?

As I recall the Mustang parts dealer was Tony Branda somewhere in Pennsylvania. (Probably find him on the Internet) There was a special on when I bought the wheels. Four for $575.00 which included the lug nuts and centre caps. The guy was real good to deal with.

I'm running Halibrand Engineering 5-Spoke wheels on my avanti. You can order them with specified backspacing. The ones I ordered where 15" x 6" with 4" back spacing. I have the the Turner disc brake kits on the front and rear of my Avanti. The tires are Firestone FireHawk Indy 500's that are size 215/70/15

Looks nice, but I was wondering what your parking/emergency brake is. Do you have one on the driveshaft or do those rear calipers activate somehow? You may not use one, but many states require them for inspection (on cars that originally came with them).

The photo was taken probably before the cable was installed. If my memory serves me correctly, the Turner kit uses rear disc calipers from a Cadillac application that allows for setting with a cable pulled emergency brake. Therefore inside the emergency brake will be applied with the original factory "T" handle from under the dash.

My 67 came with Magum wheels and 235's on it. Last year I replaced the tires and went with 235's again as they seem to work great without any issues on the car. The 235's o are one size oversize I think

Thanks for the fast reply. Branda is still selling the Magnum 500 rims from his web site, but prices are up substantially:

Set of 4 15x7 Magnum 500 rims, with 20 lug nuts and 4 Pony center caps $734.95

Branda is offering free shipping at the moment. He indicates the rims are made by Specialty Wheels Co.

Here's the site:
http://www.cobranda.com/index.html

I just wanted to confirm that you bought the 15x7 rims and that the standard Mustang offset works well for a 1963 Avanti. Do you know if any spacers are needed for the Mustang rims when mounting to the original Avanti front disks/rear drums?

that's a little more than i paid in '99, but i think the parent company is in the southeast, so maybe the shipping charge is more to you than it was here. it got here in about a week.

i doubt you could get the same price or get it much faster from a local dealer unless they are a former saturn dealer and just happened to have one in stock.

definitely worth the 26 bucks! :)

The Mustang Magnum 500's fit perfectly on the rear of a 63 Avanti with 215X70X15 tires. The fronts require a 3/16" spacer both for the original Avanti disk brakes or the Turner kit. I have had these for the past 5 years and work well.

I'm fixin' to order my wheels tomorrow. {Monday} What are the 3/16" spacers I hear ya'll talk about? Are they just thick washers you put on each lugbolt? 3/16" is not very much.

Gunslinger
02-19-2012, 09:28 PM
Spacers look like a flat disc with a series of holes or slots drilled in it to fit a variety of bolt circles. They simply fit between the wheel and hub so the calipers clear. If you have a choice, get steel spacers instead of aluminum...aluminum can crack if the lug nuts are torqued too tight.

Thanks so much for all your help. I ordered my wheels today and I am having my tires made this week. So I am ready to go to the big show in Myrtle Beach in March. Thanks again for all ya'lls help. Tom

Both Larry's Thunderbird & Mustang Parts and Coker Tire sell those wheels, too, should anyone be price-shopping.

(I only have a 2008 Larry's catalog, though, so am not sure of his current offerings.) BP
