Default Are the Z1 Star Specs too aggressive for my needs?

I just bought some DPT's 17x9 +42 for my bugeye. I need some 245/40/17's now. I'm trying to decide how aggressive to go since I daily drive the car about 8k miles a year (mostly highway), but also autox about 4 or 5 times a year.

I've been advised to go with Dunlop Z1 Star Specs (Extreme Performance). The price is about as high as I'd like to go at $150/tire and research has shown me only good things (7.78 review), but I notice a 200 wear rating.

Since I'm only autox'ing 4 or 5 times year should I drop down to something less aggressive with like a 300 wear rating?

The Sumitomo HTR Z III (Max Performance) are sticking out to me with a review of 7.35 and 300 wear rating and only $100/tire.

Or another level down (Ultra High Performance) to the Bridgestone Potenza RE760 Sport with a review of 7.19 and 340 wear rating and $120/tire after rebate.

What do you guys think?

Wear ratings don't always mean a whole lot, plus it's hard to compare them across manufacturers.

Each manufacturer gets to set it's own standards for wear rating, so one mfrs. "200" could be another's "100."

I personally would spend the extra for the Dunlops, but then I don't mind replacing tires once a year either.

Wear rating are not that good of a measure. My stock RE070 wear like iron and have a 140 rating. I'm on my second set of take offs at 50,000+ miles.

if you want to be competitive at the AutoX the Star Specs would be a good choice.

give me a call directly or use this LINK to place your order.

Star Specs are bad*** (I am running them in 225/45-17). I also agree that the wear ratings don't mean ****. I got almost 25K miles out my last set of tires which were Bridgestone RE01-Rs. A good alignment and a proper rotation schedule goes a long way. I get a rotation/balance/alignment after every other oil change (6k-8k miles), since I bought one of those 5 year plans.

Also, my usage is very similar to yours being that my car is a DD and I only AutoX a couple times a year.

If your priority is dry grip from an ST tire then get the Kumho Ecsta XS. XS gets the best lateral dry grip. Look at the Tire Rack spider charts.

Don't get confused. Extreme performance summer tires are all about dry grip and the kind of handling you prefer, not driving in the rain.

But, you can get better wet performance and easier handling with the Star Specs with dry grip that is close to the XS. Pay more and there are extreme summers out there that do even better in the wet.

If you want better wet performance and tire life with a summer tire for DD I would also look at the best maximum performance summer tires as they can outperform extreme summer performance tires in the wet.
