7" Fuchs fitment

[50/50]

I just had a 71S corner balanced and installed 26mm bars. The car has 7"
Fuchs with 225/50's. The fenders are stock but have a bright metal trim
strip around the wheel wells. ( was this a factory option?) The suspension
tech is very well known in southern CA. I haven't seen the car since the
work was completed but he says the ride height is perfect. The question/problem is the tire is hitting the fender on hard bumps. He says
the rim is too wide. I have seen 7's on many stock 911s. Any ideas before
going back to 6's?
thanks

I had 7s with Mich XWX and didn't rub with a euro ride height. If they are rubbing ask where. If they are at the lip you may want to run a narrower wheel. If up in the arch, I'd say tires. The 7s look so nice. If you want to sell let me know. I know of a good home!

The real problem with 7"s is if the tire hits the inner fender, say on a big bump,the tire will burn the paint on the outside...ask me how I know. If it hits the fender lip the tire gets chewed up and you might want to be very careful with the chrome around the lip...they may be difficult to replace as that option was fairly rare.

Second isssue is that Porsche bodies are not stright and equal. The height difference may be up to a 1/4" one side to another. That problem is fixed at the alignment/weight and balance shop.

The trick setup is to have Harvey Weidman turn your 7"s into 8"s. He changes the offset and vola you have eights without rubbing!!! I'm running 205-50 X 16", 8"s in the rear and 7"s in the front.

I have run 225-50 X 15" 7"s and 8"s both needed the fender lip pulled out on a stock 69-T.

Hope this helps.

The wheel arch molding was a factory option starting with the 1969 E and S models which carried over through to 1973. Depending on how bad the tires are rubbing, you may be able to get away with rolling the edges of the wheel arch from 11 to 1 O'clock. A wooden baseball bat works real well. Idea is to coax the inner wheel arch lip up enough to clear the tire by rolling the bat between the tire and fender. Just a thought. Good luck Allan

Tire widths vary drastically from manufacturer to manufacturer within the same specs. I know it's not much help but, some can have success with the same basic wheel/tire (size) combo where you will have difficulties...

FYI... Quoting a friend on another board:

I've now gone from running the fattest tire you can squeeze on a factory Fuchs wheel to the skinniest tire you can fit on a 7" rim.

I measured a few 205/50VR15 tires and needless to say they are all different.

*Yokohama EVS ES100 overall width is 8.2"
*Falken Azenis overall width are 7.875"
*Cheapo Nankang ex-500 overall width are 7.75"
*BFG G-force Sport overall width are 8.5625" These things are FAT!
