Rear Tire Rub

flint38 · Posted: Thu Nov 03, 2005 9:13 am Post subject: Rear Tire Rub

Hi All!! I have these exact wheels on my 71' fasty and they rub like hell in the back. In addition to new shocks , i think that a wheel with different back spacing might help. Im not hung up fatter vs. thinner tires, just want to drive my car without popping a tire from rubbing. http://www.thesamba.com/vw/classifieds/detail.php?id=212386 does anyone recognize this type of wheel, do you think its the cause, and what is the backspacing? the wheels came with the car, and god only knows which owner put them on. Thanks

Pics of them on the car would help. If it is close, you might be able to dial in some additional negative camber in the suspension. You might be able to get some earlier (supposedly shorter) axles, too. Can anyone comfirm this about the axles?

If they are rubbing on the inside, changing the offset with studs and spacers will work. If they are rubbing on the outside, (rubbing the inside of the rear fenders) the offset is wrong and you are going to have to go with different wheels or modify your suspension.

you could roll your arches, take the wing...sorry rear fender off, then cut the lip off the inside of the arch, had to do it mine, extremely low type 3 with wide low profile tyres, so the wing would of just shredded them
but no doubt someone will come on and say blah blah dont roll your wings but its up to you

Those aren't Porsche wheels, they are factory alloys available during the '70s. they are 5.5 inches wide. They shouldn't rub, unless you have something wider than the 165R15 for a tire.
I have 205/65R15 on AE 8-spokes, they rub, so I had to fold the inside of the fender lip over. I used channel locks wrapped in cardboard, or you can use plier covers. Ther was minimal deformation to the visible outside fender lip.
If you have air shears or a cut-off wheel they can be trimmed after you take the wheel off, but this will damage the paint and require finishing work. Grinder and primer at the minimum.

I put short axles on my car. They're pre-1967 Bug Axles I believe. We had to use a press to get the bearing housing off and put the type 3 housing on. Im not sure about the compatabilty with the IRS on your car though since mine is a swing axle. On my car with 8-spokes I had about 2mm of fender clearance before putting the short axles on, and about an inch afterwards.

thanks for all the good advice guys! I'll try to borrow my buddys digital camera this week and post a pic or 2. Its kinda driving me crazy when I have a mechanic here in town telling me that the car originally had 14'' rims, the tire store guys are telling me my shocks are dead but the rims are the right size, and the local foreign auto part store dude is tellin me I have to much backspacing! ARRGGG.

Once I post the pics maybe you guys can help me get to the bottom of it.
Thanks again guys! Ill post again soon.

Well i can tell you now that they didn't come with 14" rims!!
Stock it 15" 4.5 inch wide

i have those rims on my fastback. i'm running 165R15's and in the rear they were millimeters from rubbing. i did what someone suggested and rolled the inside lip of the fender to give it a little more clearance. i can barely fit a figer between it now. unfortunately you cannot use shorter bug axles since yours is irs. i would like to know how they fit on your car with 165s, since i have not found out if there is a width difference between IRS and Swing.

Here is a link to some photos of my fasty. You can get a sense of just how close its riding right now, and Ill post some more close up picks of the rear tire area. just by looking at the pic of tripicana's fasty, I can tell mine is rideing a little low, It does have 165's all aroundhttp://groups.msn.com/AircooledVW/flint38sfasty.msnw
thanks again guys!

Man is that thing pink. Wink

Yeah, it looks a little low in the rear, as well as being tight with the tire to fender. More than likely the offset of the rims are for a bug, as you shouldn't be that tight that low. Normally with IRS, you'll start tucking the top of tire inward when it gets lowered, but yours isn't doing that, so it must be torsion bar sag. Rolling Eyes

I hope this helps.
