Well, really, the title of this thread ought to be "Falken tires", specifically the Azenis RT-615k's. I've had three sets of these tires on my '85 S2 5 speed in the past four years, and while I like them...they are starting to get expensive.

The RT-615's are basically a DOT approved autocross tire, with a tread wear number of 200. Sure. On a good day! They STICK LIKE GLUE. When these tires are new, they are unbeatable. I think there is a Michelin Pilot tire that seems to get the same reviews, but it is also twice the price. The RT-615's have been all the rage among autocrossers the past few years as a result.

-And they "vulcanize" or get HARD very quick! And then they wear right out. How fast do they wear out? Well, I put about 2500 miles per year on my 928, with 95% of the driving on city streets in warm south Florida. These tires seem to stick very well for about 5 months, and then they get Viagra and become hard as rocks. One year after I buy them, they are nearly down to the cord!

I don't race my car, I don't autocross it, but I don't have much wear on my brake pads either. I use the handling capability of the car to toss it through turns at whatever speed I am. Also, every day that I'm home, I make a point of at some point going to full 100% power for at least 5 seconds in order to keep the engine clean, and also as just a chance to estimate the state of the components of the injection and ignition. I have an A/F gauge in the glove compartment, and I look at this while I run the car to 60 mph.

The car is an S2, 310 hp from the factory manual. I have an ignition chip, an Ott X-pipe, Borla dual exhaust, a rising rate fuel pressure regulator, and an A/F gauge. The car runs right, so it is certainly making more power than the manual says. The limited slip is working correctly, the car was aligned on a Hunter DSP-4000, and the ride height is correct.

So the long and short is that I'm really not "beating" on the tires. They are simply race tires, and not the best idea for a daily driver. GAWD I love those things on the rear when they are new though!

Well, up until recently, I could buy the Falkens for $110 each front [235/45-17] and $140 each rear [275/40-17], so they weren't expensive at all. Apparently the people in Japan that make Falken tires caught wind of how well liked their tires are now, and they've jacked up the prices by about 50% in the past year! The hell with that, I'm not made of $!

Surfing tires last week, I found these tires for sale from a company called Vredestein out of the Netherlands. This company has been around forever, but up to this point they sold mostly snow tires. Giugiaro has apparently gotten involved with them to design the tread, which looks like a Formula One rain tire. Check this out: It says on the side wall "Made in the Netherlands". I didn't know that tires were made in western Europe at all any more!

Anyway, the treadwear number is 280, and I bought a pair for the fronts. My rears were into the tread a month ago, so I bought two more Falken RT-615's, but when these wear out I'll pull two of these Vredesteins for the rear, and see how they do.

Vredestein Ultrac Sessanta. The treadwear is 280, which is medium. I've been putting 235/45-17's on the front for the past few years with good results. The rear Falken RT-615's in 275/40-17 size are the culprits; They wear as I've described, the fronts much better. I bought new rears about a month ago; When these Falkens wear out I'm putting Vredesteins on back there to keep the car the same all around.

Anyone know anything about the Vredesteins? I'm pretty sure they just came out.

Hey Normy, Tires are an expense on these cars.
I first tried the Yokohama's at a 300 ware and with moderately aggressive Driving while on holidays they made it home after 4500 k and only had 30 percent left on them. (the car was loaded with camping gear)
a used set on Michelins that were on some rims I bought made most of the next summer but I cut the season short. Last season I ran the Falken ZE 502 and they are a harder tire around the 400 ware which seem to last longer but IMO the Michelins are a quieter tire.

yokos before and after 5500k

Looks like you got the Winter Tire - the Vorti is summer. I will ask some of my Dutch and Belgian colleagues how they are thought of over there.

ULTRAC VORTI

The Ultrac Vorti is an Ultra High Performance tyre in the absolute top segment of the market. The tyre was developed in close collaboration with the Italian design company Giugiaro, and its slimline design and asymmetric profile give this tyre an extremely sporty and unique appearance. The tyre excels in terms of grip, handling, comfort and braking behaviour on both dry and wet road surfaces. By making use of innovative technologies, the tyre is also surprisingly quiet. The Ultrac Vorti is also available in rear axle sizes with an adapted profile and specially-tailored structure, especially for sports cars that have different tyre sizes on the front and rear axle. Due to the fact that it is the front tyres that dissipate the majority of the water when the road surface is wet, the focus for the rear tyres was on increased grip and stability.

The comments above about front vs rear design is interesting...esp for 928'ers They even have 928's listed in their pull down menu for all model years...don't see that everyday.

1983 928S - 16v 4.7L L-Jetronic
Dark Grey w/ Blue Leather
85/86 exhaust manifolds

Hey thanx Stat!

These are the "Sessanta", which sounds like a cheap Toyota or Nissan. They aren't mud + snow tires; We don't need those in south Florida. These are their new Giugiaro-designed performance tires, which are summer-only in other climates.

I remember Vredestein tires from back in 1984 when I owned my first car in Michigan, a '77 VW Rabbit, and bought my first edition of "VW & Porsche" magazine, an excellent mag geared toward regular people who worked on their cars which.... eventually morphed into the glossy review of monstrously expensive cars owned by rich idiots now called "European Car".

My subscription to European Car magazine expired during the late 1990's. On purpose-

Anyway, I was wondering if anyone knew anything about their sport tires. I suspect that I'm going to be the "guinea pig" on this one-

Hello Brad- I hear you!

Yeah, I've vaporized a few Goodyear blimps worth of tire rubber since I bought my 928! I've enjoyed every bit of it, so it is money well spent.

I went to post a picture of these new tires, but the pic from my camera is apparently too big? I'm on a Mac now, and don't have the photoshop I had three years ago that would have easily changed the format and downsized the file....

I still think Apple products are better-

I think that I would rather have the tread design on my tires created by a tire engineer than by an Italian designer...

Yeah, I thought about that.

-Well, the company has been around for a long time, and the treadwear number of 280 is harder than the 200 on those Falkens, so I'm hoping to get more than a few thousand miles out of them. And I want the same brand all around, so next year I'll put the Vredesteins on the back and give them a try.

I'm sure that they will last longer than the 2500 miles or so that I'm getting out of the Falkens!

Vreds have been around in various configurations for many years,as you cite- including some performance models. For european snows I generally think of Nakoian....
I was chasing a set a couple years ago but had trouble finding a U.S. vendor. Any tips?

Cape Cod? I seem to remember someone who lived part time in West Florida and Cape Cod. Is that you?

Anyway, I buy all my tires online and have them installed by a local tire shop that is happy to do so. If you want exotic tires like the Nokian Hakkapeliitta [Can you tell they are from Finland yet?] you can try www.tirerack.com , or www.discounttire.com . I simply did a web search about tires in the size I wanted and found a place that sold them to me. There are DOZENS of online tire vendors.

THanks. I had trouble hunting down Vredstein retailers online but I'll recheck. I didn't think discount or the 'rack carried 'em. For online, I always check tires-easy / delti.com as well, have had good results particularly if bargain shopping.

I don't do the snowbird thing- have a few years...well, decades...left of work until I could adopt that lifestyle..and actually I probably will still have other constraints at that time. But even if I could, Cape Cod would likely be the southern extent, not the Northern one!
