Widest tire that will fit under rear of 1977 Porsche 911S

What is the widest tire you can fit under the rear of a 1977 Porsche 911S with a 911 Fuch 16x7 wheel?

Search is your friend -- your car's commonly referenced as a "midyear" -- search the forum for "midyear tire" and you'll find threads that address/discuss this very issue.

225 50/16's will fit with enough negative camber. They may rub a bit on the inner fender on hard cornering during acceleration. That's about it with those wheels.

Diggem,

I have a '74 mid-year and the widest tire that I have been able to fit is a 205/50/16. However, you can get a wider tire in the rear if you switch to a Porsche 944/951 16x8 Fuchs. This is because with the 8" 951 Fuchs the added width is 1/2" on both the inside and outside of the rim. A 911 16x8 will not fit as all the extra width is on the outside edge.

My car with 205/50/16 rear and 195/55/16 front:

Widest wheel/tire under narrow (midyear) rear flare?

At stock height & camber settings, with original 15x6 Fuchs and Pirelli 205/60-15 rubs the fender, (not the lip).

OK on right side.

I've experienced tire rub on my '77 running 205s as well, didn't happen with every brand, but on several. I finally got sick of it and went with 195s.

If you don't mind running a tad smaller diameter tire, you can get a 215/50-16 to fit with 951 8x16.

I used to run 215/60-15 on 911 7x15's with rolled lips and minimal rub.

I think the 195/50-15s lowered the car about 3/4 inch. and the improvement in grip, (over 20 year old Pirellis :-) was astounding, not to mention a little improvement in gearing.

Would it be safe to run 205/65 15" tires on a stock ride height '77 US spec Targa ? I don't want any rubbing.
