Dave I thought of one other tire that I tried albeit as take offs; Avon ACB9. I used a 6.0 x 22-13. They are used on classic Formula Fords and small bore sedans. Again it's a bias ply but it should easily fit under you fenders and they fit on Rims as narrow as 5". You might be able to find them as take offs for cheap.

Hi Tom,
I have thought about these however after talking to a chap who has tried them on his 1200 evidently they are good for 1 lap then just get too hot and go off very quickly.
Interestingly I googled the Yokohama A050 and believe it or not they make them in a 175x60x13 so I rang the importer here in NZ to see if they had/could get them only to be told that they were not bringing any 13" A050's into the country - even after offering to prepay for them. Typical NZ !
Well buggar them- I quickly had a look on the net and found a Japanese site that exports so will contact them for a quote.( and our retailers wonder why they are losing business hand over fist to overseas suppliers via the net!)
So a few options on the table- still waiting to hear on the Nankangs.
Watch this space!
Cheers

Hi Tom,
Just had a quick look at the Hoosier site. Gosh, those R7's look the goods. There is absolutely nothing available here in NZ unfortunately.
What sort of money are you paying for them over in the States?
Cheers
Dave

Hi Dave you could try MD Motorsport (Max Dumesney) he is the importer in Melbourne for hoosier tyres.Greg

Dave,

For current Hoosier Street TD I'm paying $185 per tire. The 185/60-13 R7 are $195-200. Last week I email Hooiser for some help deciding whether to stick with the Street TD or go to the R7, my concern was the wieght difference (the TDs are only 11lbs). I was told for the my 100whp car that I'd be better of with the TD. They also told me they are coming out with a new / updated tire, 20.5 x 6.0 - 13, which offer more grip and will also go a few more heat cycles as well. It's due September / October. Basically they are waiting tell the sell of existing stock of Street TD, which means they may have some smoking deals on the older tire.

Now as for those Avon overheating, yes it is possible to do them in very quickly, they are fine for anything sub 1500lbs. When I ran them on my car it was 1780 with me in it, much more than that I bet you could cook them in a couple of laps. If I was doing untimed track days I'd buy a used set to play with. They were heaps of fun, with a bit taller sidewall then the Hoosiers you could hang the car waaaaaay out. My buddy whose known for wrestling old dirt bikes in the most alarming manner commented "those sure look like fun", total giggle fest. If there's timing I'll be on the Hoosiers.
