FUCHS SIZE on narrow G BODY

[lifeonmars]

What size FUCHS wheel will fit a 77 911S narrow G body?

[Showdown]

Kinda depends on a lot of factors;

What tires?
What rear suspension height?
Camber?
Rolled fenders?

There are literally dozens of threads on this topic that are comprehensively exhausting.

Short answer is 6x15 are safe, 7x15 are doable with a bit of work, 8x15 are possible with some effort and magic.

The first place to look for info is Bill Verberg's page on wheel fitment.

I have 15 x 7 on my ‘76 narrow body. They fit really well but I think you have to be very careful with the the tyre size/ profile. I run 205/55 without any issues. I think with 60 series it might hit the front guards. Rears wouldn’t be an issue.

I run 16 x 6 and 16 x 7s on my narrow 74 with 205 50 16s...no issues.

I run 17x7 Euromeisters. Nothing over 7.5" is going to fit without metal work imho. Sucks. Every time I see a set of OG 80s/90s aftermarket wheels with 5x130 bolt pattern, they're always staggered and wide AF/completely unusable for my car. I'm never doing flares.

Thanks for the help everyone.

I have 5.5 x 14’s…1977 S - Comfort Package for now, prefer steels in 15” for retro look.

FWIW, your car has the same front fenders as later "narrow body" 911s (with flared rear fenders) -- 16x7 will fit up front and fill out the front fenders quite nicely. Depending on tire selection (205/50-16 would provide more clearance than 205/55-16), you might need to roll the inner front fender lips a little bit. Could be nice to run tires/wheels "square," as it'd enable you to swap front to back and extend overall tire life.

I mentioned this on another thread about tires, but maybe it bears repeating.

I have a '77 and went with 6x16 and 7x16 with Dunlop Direzza 205/50/16 in the front and rear.

In the front, there was no issue, even with the car lowered to just below Euro height (we're talking like 1/4" below Euro). In the rear I had to roll the fenders and give 1.2 degrees of negative camber to facilitate clearance and I still got some sidewall rub on big dips and bumps.

After a summer of driving them I decided to change. While the combination would be great for track, for streets it was unpleasant. The lower profile tires and larger rims made the ride very rough and harsh. Not to mention, my stock 2.7 really didn't need that extra rubber.

I went with 6x15 all around and 195x65 Riken Raptors (Michelin made tires) and have to say it's a world of difference. The car feels softer and the steering is most definitely lighter. With the 2.7 it really feels more fun on the narrower and larger tires. It's not a modern car "on rails" and it wasn't ever supposed to be and that's actually what I love about it.

I think there's a temptation to throw on bigger rims and low profile tires because that's what we think of as high performance and that's what all the high end builders do... but keep in mind that many of those cars are pushing 350+ HP. It's fun to make the car look more aggressive and "cool" but there's often a huge trade off in actual driving experience.

Just because you can, doesn't mean you should.

Julian -- interesting observations. My 3.2 carrera came stock with 16x6 front and 16x7 rear wearing 205/55-16 front and 225/50-16 rear. I've been running relatively compliant tires (Most recently Michelin AS3+, previously Continental DW summer tires) and haven't had issues/concerns with a rough/harsh ride on Denver area streets/etc., but would expect more track-focused tires (such as your former Direzzas or Yokohama AO52) to be a fair bit harsher. Guess my point here is that the type of tire one chooses (Grand Touring for your Raptors and my Michelins vs Ultra High Performance ) may well have as much effect on ride/etc. as tire size does.

Exactly the same here. I did not want to roll or cut my pristine fenders/paint, but wanted a bit wider wheels because I had upgraded to a hot rod engine (but still wanted 15s to help with acceleration vs taller wheels). I experimented and was only able to get 7x15 on front and back of either of my '74s...and wanted the car to appear as original/stock as possible. Even then, the tires rubbed until I specifically searched for the specific brand of tires that measured a bit smaller for the size where they rubbed. Then, still had to stiffen my suspension (larger T-bars) to keep them from rubbing in the back on bumps (already had new shocks/struts and tweak the positioning of my Carrera cooler in the front right wheel well as on some turns, the tire rubbed on that.

Well.... after more thought I'm thinking 15" X 7" set would be great.

Good decision

now follow up by keeping the tire OD down

[ADDvanced]

Just FYI you usually list the diameter first, then the width. So 15x7.

[lifeonmars]

Any tire brand and size recommendations? thanks for help

I run 205/50s on my 16 x 7" Fuchs on my lowered 77, with a 6mm spacer on the rears and the rear arches rolled. I like the Goodrich G Force Sport Comp 2s I've had for about 5 or 6 years, but Tire Rack is showing the Firestone Firehawk Indy 500 just slightly higher in the subjective rating for tires in the ultra high performance summer class. The rating was almost identical, with the Firestones having a firmer ride, which I may not want but someone else might...

This size yields a slightly smaller overall diameter, which throws the speedo off a little, but I like the lowered look and the added acceleration.
