Best tire & size choice for 1977 911

I need to replace my Yokohama's on my '77 coupe. Looking for opinions on replacements. Please let me know your favorite brand and tire size.

Thanks.

I’d go ahead and put on a Nomex suit before other replies start rolling in.

You might want to post your wheel sizes?

'77 tires

My wheel size is 15"

I was running 205x60x15 Yokohama's. Then I found out one rubbed just a little on the passenger rear against a braided oil line.

I just bought four Vredestein Sportrac 5 195/65 R 15 from Tirerack at a very good price - the size is similar as the 185/70 that was the original fitment

I run 205/55/16 in the front, 225/55/16 in the back. I like the kuhmos ectsa PS31. I used the ectsa Supra before but they don’t make it anymore. Inexpensive and good tires. I really like the lower profile 55 tires on 16 inch wheels, but it may not work as well with 15 inch wheels.

I like my 195/65/15 Goodyear Sport Eagles it's a tossable V rated tire that is solid and not too expensive.

I like my Continental ExtremeContact Sports. Use them for everyday, HPDE and rain tire for Autocross (in place of my Hoosiers).

Most '77s would have come w/ 4 x 6x15ET36 wheels and 185/70 x15 tires

If you are going for originality Pirelli CN36 in that size are the tire to use

later in the product cycle life 195/65 x15 were supplied in those wheels

all of the above tires are ~25+" tall

for a biy of a performance boost 205/55 or for more of a boost 205/50 can be used on the 6s, I'd avoid 20/60 as that is even taller than oe is is a drag on performance

There must be a custom oil cooler setup on that car for the 205s to rub, w/ 205 the backspace is around ~5.5" and most 911s even w/ stock oil lines can get away w/ ~6"

Have a look at the Yokohama Advan Fleva which looks like a replacement for the S-Drive which I am running on my 77 coupe. Loved my S-Drives.

I am using Continental ExtremeContact Sports 205/55-16 on my 1973 with 6x16 Fuchs. There were no rubbing issues after I upgraded to Turbo Torsion bars. Prior to that I had a rub about 1-2 inches above the fender.

When I use my 205/50-15 Hoosier SM's on my 6x15 Cookies, I had a rubbing issue where the tire shoulder would rub against one of the nuts on my right spring plate. This was resolved by installing a jam nut in place of the stock nut, cutting off the exposed threads and adding a 5 mm spacer.

Interesting

I've seen 215/60 on 7x15ET23.3 rub a couple of inches up into the paint in back, the back space in that combo is ~ 5.5" too. Same as 6ET36 w/ 205/55, Hoosiers do run wide in the 205 size by ~.4" over other brands

Generally contact on the inner side at the il line and a trailing arm bolts occurs at b/s ~6"

Here's a tire w/ 6" of back space
