My car has 205/50/15's on it which make it squirt out of a turn from low speeds. OTOH, the ride isn't the finest but I can live with it because I have cars that ride nice.

I've come down with some choices mostly based on dry grip and not so much about ride quality. Sizes are limited.

Dunlop Direzza in 205/55/15 to add some height (although a 50 series is fun!)

G-FORCE SPORT COMP-2 - SIZE: 195/55R15 because that's all they make

Pirelli P6000 185/70/15

Avon in either 175/70/15 or 185/70/15

I'm familiar with the Avon from friends who run them on early 911's. There's a guy who uses them on 4.5 Fuchs in the 175 size and they say he's not easy to get away from on a back road.

Opinions welcome.

OP doesn't specify rim width, but I've been looking for replacements for my 205/60/R15 Goodyears which I haven't been thrilled with, over7X15 Fuchs, so I appreciate the topic. 205/55/15 sounds like a good option.

Out of curiosity, what is your objection to Pirellis, other than possibly price?

The new car I picked up has Yokohama S-drive, 205/55-15. No idea if they're any good but they're a summer sport tire.
I like a bit taller tire to fill up the wheel well, I wish they came in a /60.

Here's an interesting article that compares several period style tires.....Vredestein, Michelin, Pirelli and Blockley tires in the 185/70 R15 size. The Vredestein stacks up pretty well.

From this thread:
http://www.914world.com/bbs2/index.php?sho...39516&st=20


I'll leave the 14s and the CW tires to Coker Tire (where you can also buy Model T tires) and stick to what appealed to me as period-correct (or at least not "period WRONG") and still sporting options for a narrow 914 after a ton of personal research, phone calls, internet surfing, etc.

Coker Tire/Michelin XWX 185/70R15 (the hot tire of the day, standard equipment on the 911S and the +0 upgrade for 914s)
Notes: Can't get my head around $348 each for a tire this small, with such dated technology. Too concours/show & tell-oriented for me, and way too expensive to boot.
Find them here: https://www.cokertire.com/tires/michelin-xwx.html

Vredestein Sprint Classic 185/70R15 (the reasonably priced tire if you want period looks and decent performance)
Notes: Period tread pattern and sidewalls, probably better than the Coker Michelin XWX and a LOT less expensive at $140 each; nice steering response, nice ride, not so great in terms of ultimate grip. Bought a set 8-10 years ago. Just weren't for me, but a lot of people like them.
Find them here: http://www.vulcantire.com/cgi-bin/tiresear...t_classic_t.cst

Avon CR6ZZ 185/70R15 (just bought a set, will mount them shortly...)
Notes: We'll see about ride and handling, but everyone raves about them; definitely have the period look, with tall, plain sidewalls. Available in three compounds, with 29 being the hardest and 31 being the softest (you want 29s for the street). Narrower than I wanted, but I am told even the hardest version has a LOT more grip than any street-spec 195 or 205. Roger Kraus Racing carries them for $280/tire. Not cheap—unless you compare them to Coker XWXs. They do seem like good value against a modern N-spec Porsche tire, given their specialty nature—though they won't last as long. You can also get CR6ZZs in 215/60R15.
Find them here: http://rogerkrausracing.com/pages/pricing.html

Dunlop SP Sport 195/65R15 (a good middle of the road, affordable tire with reasonable grip by modern standards and a sidewall and tread pattern that don't look completely alien on a 1970s car)
Notes: Sidewall too modern for me, but better than most. A favored tire of Rod and Gary Emory for street-oriented 356 hot rods where Hoosiers won't work. Grip okay, ride okay, but distinctly not sporting—even if they are probably superior to the best tires of the 1970s. Bought a set, but am taking them off after 1,000~ miles. Just not for me. But: $65~ each is a bargain for what you get.
Find them here: http://www.tirerack.com/tires/tires.jsp?gc...0160211172230:s

Michelin Pilot Sport All-Season 3 205/55R16 (what a great street tire!)
Notes: I almost moved on to 16-inch wheels just to mount a set of these. I put a set of them on our 2013 Abarth at $129~/tire and it may be my new favorite street tire. It's AVS Intermediate good, and maybe better. Crazy grip (better than many summer tires, apparently), very quiet, and carries a tread wear rating of 500. I'm not expecting that long a life given the grip, but will be fun finding out if it's hogwash. If the Avons don't work out, this may be my next plan.
Find them here: http://www.tirerack.com/tires/tires.jsp?ti...romCompare1=yes

Michelin TB & TB15 (perfection, at a price)
If I was running a GT-flared 914 on 15-inch wheels, and perhaps one day I might be, the choice would be a lot simpler. I'd run Michelin TB15 tires (vintage race/tarmac rally tire) on 15x7&9-inch Fuchs. They have wonderful grip, REALLY nice steering response, and killer good looks. Jeff Zwart is running them on his yellow 914-6, and I was blown away by them. The fronts are 215/55R15, the rears are racing sizes but not all that hard to figure out for the back of a 914 (the same size as the front of a RSR 2.8).
Find them here: http://www.summitracing.com/search/product...elin-tb15-tires

Hope this is helpful for someone else!


Will say, with hindsight, I would have done the soft-compound CR6ZZ over the hardest. They wear better than expected, and I wouldn't mind something softer.

I'd also take a hard look at the P6000 N2 in 195/65R15 (might be a better street tire, and the 195's bulge looks great on a 5.5- or 6.0-inch wheel), the Yoko A-048 in 205/60R15 (may rub a bit, depending on your 914's rear fenders), and the Direzza in 205/55R15 (ran 205/55s for years, and liked them, but have wanted a taller sidewall lately). It's really too bad the Michelin AS/3 isn't available in 195/65R15...would be the perfect 914 tire. Simple sidewall, timeless tread, great handling in any weather, etc.

"Dry" handling numbers in the 8's are more to my liking. Grand Touring tires are generally in the 7's. As a 100% fair weather driver, wet traction isn't a concern.

Pirelli P6000 - 7.9 dry (195/65)

Goodyear G-Force - 9.0 dry (195/55)

Direzza DZ102 - 8.7 dry (195/55)
Direzza ZIII - unknown but should surpass the DZ102

Yokohama S Drive - 8.6 (195/55)

Toyo PROXES R1R - GOK? They are liked by the go-fast crowd.
Yokohama ADVAN A048 - 9.1 (205/60 or 205/50) Pricey but here is your 205/60, Mark. (IMG:style_emoticons/default/piratenanner.gif)
(They won't to win any wear or ride contests but they do work.)

I just had a set of Yokohama 205/55R-15's shipped to Harvey for my wheels. The price is right and it gets a set on the car and if I am able to then upsize down the road, I would prefer a 60 series, then I can do that with ease. But for initial fitment I needed to know how it was all going to fit. I had my deep sixes widened on the back side by 1" and we raised my spindles by 17MM. I am hoping to be able to pick them up this coming Saturday morning. (IMG:style_emoticons/default/beerchug.gif)

Letting Harvey mount them is the best money you'll spend.

He once told me the story of a set of wheels which a restoration shop wanted to mount the tires themselves. (He offered, they declined) The shop ended up damaging a wheel which required it to be sent back for another restoration. (IMG:style_emoticons/default/headbang.gif)

Exactly why Harvey is mounting and balancing them. Just makes sense. (IMG:style_emoticons/default/beerchug.gif)

Falken Azenis 205x 50x15 sticky summer street legal. No penalty for rating at AX UTQC 200
Toyo Proxes R888 similar with more sizes.

Note: check overall diameter for any tire you choose. It dramatically effects your gearing> This can be a help at autocross depending on speeds expected along the course and the amount of shifting you will need to do.

Don't get tires like this if you plan to drive in rain.....

Have you guys tried the new Pirelli tyres that have been tested and homologated by Porsche.

they make

165VR15 Cinturato CN36 N4
185/70WR15 Cinturato CN36 N4
215/60WR15 CN36 N4
205/50ZR15 Cinturato P7
225/50ZR15 Cinturato P7
and they are now making some more P7 tyres in 16" for later 911

Howver all things considered these are the best tyres to fit to Porsche.

I would strongly recomend keeping away from anything lower than a 70% profile tyre on your cars because they just won't handle as well. tyres like a 195/65R15 will have a carcass that is designed for a much more modern chassis.

you can get these tyres from Lucas Classic Tires in the States https://www.lucasclassictires.com/Porsche-911-Tires_c219.htm

Only thing to think about when picking tires per grip levels is characteristics.

I find I don't like most "square-shouldered" tires. They may have a lot of grip, but the shoulder design seems to have a fair bit to do with how a tire acts and communicates on the way up to its 7-8-9 in grip. I had a set of very square shouldered tires from a well known manufacturer that ruined not just my 914 but also my WRX. Plenty of grip, but with a cliff. Not too useful, and treacherous in the rain. YMMV…

of the choices listed, I would go with the Dunlops if beholden to a 55 series tire. If willing to keep the 50 series, a 205/50 opens the door to a lot more choices.

I have 14" rims.. The only sporting tire I find is the Falken Azenis 615. Its a really nice tire btw. No road noise like the R888. Sticky too.

Depending on how many miles, or your use, whatever you by will likely "time out" before it "wears out". I bought my Falkens in 2016. They are considerably less sticky now than when new, but as expected, plenty of tread left. Just takes some warming up to make them sticky again.

I have the Pilot's on my car in 195/65-15. They are what was on the car when I bought it. I really like them but they are getting old and should probably be replaced soon.

Problem is that these are no longer offered in this size and there do not seem to be many other options besides generic all seasons. I only drive her in Spring Summer.

I think I can get Vredestein SPORTRAC 5 in 195/65 R15 91H. Should I go with those or should I be considering an alternate size tire?

195/55R15 is completely the wrong diameter

80% of the correct 165 = a side wall height of 132mm

55% of 195mm = side wall height of 107mm so that tyre will be an inch too small in radius. so gearing wrong as well as handling effected.

the lower profile you go and the wider you go the more derogatory effects on handling. With racing cars, (which is totally different to road cars.) these cars are lowered with stiffer suspension, and they change the camber and caster, so it is like a wholey different car. which is then not so suitable for the road.

The effects of putting wider lower, profile, squarer shouldered tyres on a car like that are that because you have relatively soft suspension, and because the wheels stay parallel with the car (instead of adding adverse camber as the car rolls) as you corner and the car leans, it climbs onto the shoulder of the tyre lifting the inside edge, which creates a sudden loss of grip, so the idea that they give more grip, is not as clear cut as it might seem. the tyre itself offers more grip, but only when you have the chassis to suit.

Anyone who has auto-x'd one of these would heartily disagree. My car was originally owned by an ex-AF pilot who still auto-x's at 86 in a Boxster or Cayman. Not in love with the looks of a 50 series tire but they do work very well. Slot car... Go-Kart...Video Game. (IMG:style_emoticons/default/biggrin.gif)

Also have a '74 911 with Goodyear Eagle Sport tires on it. They are 195/65x15 and I'm anxiously looking forward to taking them off the car.
This is an another ex auto-x car with "suspension upgrades" and a warmed over engine. The tires don't take input without a moment of "indecision" before they take the line. That's unsettling.
