I have a 1971 914-6 clone that came with a set of 7X15 five spoke Fuchs. I am currently running a set of 225/50/15's on these rims. The tires fit under the stock wheelwells with no modifications. The person I bought the car from said the rims were from an early 911 but didn't know the year, etc.. I read somewhere about an early Fuchs rim that would allow a person to run larger tires on a 914. I recall something like a 911R, does this make sense. My brother would like to aquire the same rims but I don't know what to tell him to look for. Is anyone aware of the rim in question.

There's a pretty good chance that your stock fenders are not quite stock, if you can fit 225's under them. I have never heard of 225/50-15 fitting under totally-stock fenders on any 914 so far. Josh2 has 215 or 225 on 14" rims on his car, and they have required folding up the rear fender lip. But he says that 15s are a no-go.

I saw a Six conversion (71) recently with 225/50-15s on Fuchs 7 and 8 by 15 rims, but the rear fenders had been "rolled". A nice subtle job that was not easy to tell just by looking. I don't know what offset the rims were.

Another Six conversion (74) that I rode in recently had the 7 by 15 911R rims on the rear. These are EXTREMELY expensive (something like $1100 each??) and very rare rims. He said that all he could fit on them were 195/60-15s. The 50-series tires didn't stretch out far enough to mount on 7s, and any wider tires still rubbed in the rear.

Unfortunately, the hand-built nature of the 914 (and the less-than-perfect QC by Karmann) means that all 914s are a little bit different than each other. And clearance is tight enough in the rear fenders that a little change can mean you can or cannot fit a particular tire and rim combination.

You might be able to measure the spacing between the plane of the hub and the fender, and the clearance between it and the trailing arm and strut. That will tell you how much space you have to play with. You'll need to jack the trailing arm up and down to see how the plane of the hub moves when the suspension moves, because that WILL change the clearances. Then you can use that info to figure out tire width and rim offset. Be sure to add some safety fudge factors, since the suspension will tend to "give" at least a bit under side-loads.

Attn: Dave Darling, thank you for your response. How would I know if my fenders were "rolled" as you say. I did look in the rear wheelwells and the inner lip was bent up and out of the way a bit. Is this what you refer to as being "rolled"? I do know that the rim is a 15X7, that I am sure of. I am also sure of the tire size, 225/50/15. Is there any way I could tell if I have the 911R rims you referred to i.e., numbers on the rim, etc.? I have the same rims front and rear if that makes a difference. Thank you again for your help.

Rolling the fenders and folding the fender lip are two different things.

To "roll" the fenders, an object (typically a towel-wrapped baseball bat or piece of PVC pipe) is placed between the wheel and the fender. Then the car is rolled (or driven) forward, and the object goes up and over the tire. If the object is the right size for the particular fender/wheel clearance, the fender will get pushed outward by the object. Repeating with a larger object will push the fender out even more.

This is an easy way to tell if you have any Bondo or body filler in your fenders, BTW. If you do, it will crack and break and might even fall off the car. Old paint or paint that isn't very flexible will also tend to crack and be damaged by this procedure. Fun, huh?

I know one person who told me that he put some halfway-reasonable flares on his early unflared 911 that way. They looked very good. No repainting necessary. At least, that's what he told me.

I'm not sure how you'd tell if your fenders were rolled. It can look very subtle. You might see if you can find an unmolested 914 of similar vintage and do a side-by-side comparison.

The 911R wheels do have a particular part number on them, but I don't know what it is. You could try checking on the 911 forum, or an e-mail list, or doing some book research. (Johnson's 911/912 Authenticity Guide, or maybe Anderson's 911 Performance book.) Any numbers you find on the wheels should help you find out what kind of original application, offset, etc. they have.

I could be totally off-base about having modified fenders, too. All 914s are slightly different. You may have one that fits 225s prefectly from the factory. If so, you're very lucky.

Yup, I agree with Dave here. There is something about your 914-6 that doesn't add up. The largest tire that you can fit on the 914 is a 205/60/15. Of course, not all tires are the same size. One manufacturer's tire may fit whereas another may not. I have seen this before. 225 is pretty big though, so I predict that the fenders have been rolled out.

I doubt that you have the 911R wheels, as they are probably worth more than the car, and anyone who put them on there originally would most likely know that. (they were rare back then, and they are rare now). Check your car against some of the photos here on the site. That might tell you some more info.

Also, your email doesn't seem to be working. Give us a call here at 888-280-7799 in the eve (Pac Time), and we'll hook you up with those parts that you were looking for.

Many thanks,

The easiest way to identify the 911R wheels is to compare them to either late model 7X15 wheels which have approx.
1 1/2 inch of dish and the center spokes
are inset. The 911R wheels appear identical to the early "deepsix" 6" wheels.
They have a deeper dish than a later six
but the spokes come out further so the total effect is that the spokes are almost
flush with the rim. When the 911R's ran
with 6's and 7's on the rear the wheels
all appeared identical. Hope that helps.
