Update on 17" tire choices. Earlier this year Kumho announced a new Extreme Performance Summer tire, the ECSTA V720, but did not say what sizes would be available. They are now available at TireRack and the news is not good. They are only available (at least currently) in six sizes, the two largest of which are 245/40/17 and 245/40/18.

It seems unlikely that they would design a new tire and only produce 6 sizes so I searched for any info on possible additional sizes but didn't find any.
There is some good news for fans of the ECSTA XS which have been discontinued. Although the 315/35/17 size seems to be unavailable everywhere I looked, the guy I chatted with at TR said they are expecting one last shipment in June and there will be a very limited number. If you have to have them, you can pre-order them and they will be reserved for you when they arrive (assuming you are near the front of the line). The matching 235/40/17 size is still listed as available, but who knows if they will be in June.
I also asked his opinion of the Conti Extremecontact DW in the 285/40/17 size and told him that I didn't have any "Track Time" planned. He said that was an excellent choice for HP street use. Their price is $174 while the 245/40/17s are $126. There is quite a selection of other suitable large sizes in the 18, 19 and 20" sizes.

The Kumho ECSTA SPT is also available in the 285/40/17 size with the matching front of either 215 or 225/45/17. Both will work with 8" rims and are 24.6 and 25" dia respectively.

That's the tires I have on my car 285/40/17 and 225/45/17 I think they look good on the car. 285/40/17 were the only size I would get for a 17 by 11 rim I think the 315/35/17 are to short and 335/35/17 are to wide and too expensive
Thanks for the input. I'm seriously consideing the Kumho ECSTA SPT, just wish they had a 335/40/17 option. Of the available options, I think they are the best looking.
Richard,
If you want to see a few other views of a 285 width tire, I have some from this gallery post late last year. I went with the Conti Extreme Contact DW and I am very happy. I have them in a 19" rear, but they should look similar. My only complaint is that they are so sticky that its hard to do a nice smokey burnout.
These photos were taken before I removed the spring spacers.

FWIW, I recently replaced my 13-year old Dunlop SP8000 335/35-17 with M/T Street Comp 315/35-17. The price was right for a tire that spends its time on the street getting to/from and parked at area cruise-ins during the driving season...

@Jimlah, thanks for the photos and confirmation that they are a great tire. A question though. Why did you go with the 225/45 vs the 245/40 which is slightly smaller in dia (24.7 vs 25.0)?
@rlee63a4, what are you running on the fronts?
@rlee63a4, what are you running on the fronts?
I was afraid the 245 would be too wide. This was my first set of tires on a newly purchased Pantera. I wasn't trying to push the limits of tire fit.

@rbarkley671, Picking the front tires was a challenge since M/T doesn't make a matching Street Comp tire for the 16" wheels that I'm running on the front. So, the best I could do was look for a tire with a similar asymmetric tread pattern and tread wear rating (for what that's really worth). I ended up with a 225/45-16 Nexen N’Fera SU1. Not really what I wanted but figured the tire is Z-rated. So, how bad a tire can it be for street use.

I'm afraid that's the situation (different front/rear tires) most of us may be in soon if not already. I'm pretty content with my choice of the Conti Extremecontact DW and that the 285/40/17s on the back will look good and drive well. However, I haven't actually bought them yet as it will be three or so months before my car is back on the road.
About time for an update!! I'm committed to getting ZONKEY back on the road this year (hopefully in time for the POCA Monterey Fun Rally!!). So tires are back on my mind. If you look back in this thread, I'd sort of settled on the Continental EXTREMECONTACT DW in the 285/40/17 and 245/40/17 in front.
So, time to check what's available now (last check was in May of '15). Not much has changed AFAIKT, except that Conti is retiring the EXTREMECONTACT DW and replacing it (Feb 2017) with the new "EXTREMECONTACT SPORT"
http://www.continentaltire.com...coming-february-2017 and "including 17 new sizes, ranging from 15” – 20” " (no mention of old sizes they are discontinuing!)
Sounds great! So I called TireRack to see what they know. Sadly, not much at this time: no pricing or sizing info, at least that they would tell me.
Meanwhile the old DW's are on sale! The 285s are $155.55 and 245s are $112.45 for a $536.00 total. This seems like an incredible deal. The alternative in this size pairing is the Pirelli ZERO SYSTEM at $1,362.40 and they don't rate nearly as well!!
So, what to do? I'm strongly leaning toward the "known known" (as good old, should be dead by now if there were justice in this world, Rumsfeld would say) as I realistically, at age '72, won't be pushing things to the limit or noticing performance differences at the few % level.....

You can still find the 335/35 17 michelin pilot sports it just takes a little searching. I believe it was Joules that said they are produced in batches. I know tire rack had them again earlier this past fall.
I like the new

I've been considering the 285/40r17 tire myself, paired with the 225/50r15 up front. Available as a matched set in the Pirelli P Zero model. In my opinion the 285/40R17 (26" diameter) is too small in diameter to pair with any front tire larger than 24.3" diameter.
The chart details options where you can acquire the same make and model for all 4 corners, with good availability, correct diameters, etc.

I thought I would make it through my lifetime without ever having to hear that phrase again!
That DW pricing sounds excellent BTW. Are there any left?
LSJ
You might try Toyo R888's.
Thanks for the reminder!
"That DW pricing sounds excellent BTW. Are there any left?"
Well, apparently not too many. I just ordered a set of 4 (285 & 245/40/17) from TireRack. At least for my west coast zip (90277 so the Reno warehouse) there were less that 4 left of the 245/40s (so now less that 2). The good news is that both sizes are $112.45 + $20 shipping and no tax. The bad news is that the 285's have a mid '13 date code (TR said they should be good for ~5 years). At that price, I can live with that.
I checked other sources and most didn't have them. Amazon does and at about the same price (w free shipping with Prime) but probably add tax (8%+ in CA). They showed on 7 left (245) and 4 left (285). So, if someone wants some, they better move now.
I checked other options on TR and P Zeros are available in 335/35ZR17 and 245/40ZR17 sizes. the 335s are $632.00 each!! Michelin 335s are available for $406.70 but the closest to a front tire is 225/45ZR17 (don't know if that fits).
As for the R888's and other track/autocross tires, as I said before, those make no sense for my needs.

Tire rack called me this morning to make sure that I knew what I was doing as the sizes are not on their recommended list for the Pantera. I took the opportunity to ask him if he knew anything about what sizes the new Conti "EXTREMECONTACT SPORT" are going to be available in. His answer was that they still don't know.

I have Michelin 225/45ZR17's on the front and they fit fine. My car is a fall of 73 build and the fenders are partially rolled from the factory but not completely and the fronts never seem to hit when steering. I have the 335/35/17's on the rear.

Good to know. BTW, for all searching tire options, this is a great site:
https://tiresize.com/comparison/
As it shows (seamingly) all available tires and where to buy them. TireRack is good, but only shows that brands (and sizes?) that they carry.
The 225/45's are about .3" larger in diameter that the 245/40's. Of course, as George and others have pointed out, width can also be a factor.
Guess what just arrived. And the good news is that the 285's date code is 47/15 (Nov,'15, not the mid '13 I was told) and the fronts are 10/16 (March)
The rear's tread is only ~1" narrower that the 335/35s and the dia 0.2" less.

The Continental EXTREMECONTACT SPORT tires I mentioned above are now available. The 285/40/17 & 245/40/17 are available as before. I think this is a complete list of the sizes that are (will be?) being made:
https://tiresize.com/tires/Con...emeContact-Sport.htm Tire Rack does not list all these sizes.
Here's Conti's listing (tiresize.com seems to be the same)
http://www.continentaltire.com...ort-28540zr17-100w/?
Pick a size from the popup and scroll down and click view more to get the specs.
In the 18" size for the rear there is a 295/35ZR18 (26.1" dia) and 285/40ZR18 (27" dia) and a number of other possible options in the 19" and 20" sizes.
Prices about the same as the EXTREMECONTACT DW (before going on close-out)and quite reasonable at $203 (285/40/17) and $262 (295/35ZR18). The 285/40ZR18 size doesn't seem to be available yet.
