WHY BUY HANKOOKS?

Hoosiers recommends 4 PSI increase of left rear at Cali Speedway. Hanks? Wouldn't touch them as I have indicated before...I am sticking with Nitto NT-01 tires, 30% less than Hoosiers (Maybe Hankooks too for that matter...not certain, but I always get at least 20 good, no compromises on handling, heat cycles froM NT-01 tires. In 18" NT-01 rears come in 275, 305 and 315. Can't stuff a 305 into the wheel well, so I get by very nicely on the 275s.

HOOSIER SCOOP ON BANKED TRACKS

https://www.hoosiertire.com/pbP28518.HTM
In cases where the size cannot be changed (FROM A 285/30.18), it is advisable to increase air pressure to insure a minimum of 40 psi (cold) for unbanked tracks, and 44 psi (cold) for banked courses.

THIS IS SOME SCARY SH*T

back to back for me b/w nt01 and c51 z214s was ~2.5 seconds at TWS. When I purchased them last, they were cheaper than nt01s too, unless you catch discount tires semi annual sale on the nt01s.

^^^ Similar for me, except I've never seen Z214s cheaper than NT-01s in the 235/40-17 size. The 214s are 245/40-17 and always seem to be a bit over $200 each. "Regular" price on then NT-01s is about $190 and if you time the sale $155-$165.

I used a set of fairly new NT01s 245/305 and a set of C51 Z214s 245/275 that had 25 heat cycles on them back to back, 2 sessions each. The well used z214s were about 1-1.5s faster but felt much much better. Posted the NT01s on RL classifieds and had them sold before I got home that day.

If you can sell a set of NT-01s with 25 heat cycles, you can sell refrigerators to Eskimos in the winter.

Let's not forget the Z 214 is a DOT 40 rated tire, just like the Hoosiers. The Nittos are DOT 100 rated tires. They are never going to be as quick as a 40 rated tire..unless you are a pro-driver.

I think you just misread it. The NT01's were fairly new. And the fact that they happen to be on a set of CCW C10's made it a fairly easy package to sell.

You do realize the loads that a bank track can put on a tire? Especially on the rear of a rear engine Porsche. Tires have blown out because they were undersized or underinflated. Most drivers under inflate their tires in general. This is a case where it is of the utmost importance to adhere to the manufacturer's recommendations.

"Hoosiers recommends 4 PSI increase of left rear at Cali Speedway. That would be RIGHT REAR

The track is run counterclockwise, so the load is on the right rear. This is a scary track...but I seem to go back at least 1X per year. Only one incident to date...blew a right rear Toyo 710 coming out of turn 2 at 125mph ish...did three 360 snap spins and didn't hit anything. Disintegrating tire ate the rear fender liner and broke the 993RS side skirt.

Lucky to walk away unscathed.

Thanks for the above replies. Would you need to increase the right rear AND front tires by 4-5 psi and if so, how much would that affect the handling on the infield portion of the track? Also, how critical is decreasing the camber to 2.0 or less if you make the pressure adjustments? I recently used the Z214s at Willow Springs with the lower camber settings and had DRAMATIC outside tire wear on the left front and to lesser extent left rear in 3 short sessions( so bad that my race shop contacted Hankook to see if this was a tire defect).In my class I can always use the NT01s ( and then take 130+pounds off my car weight somehow)but I doubt that would yield comparable lap times to Z214s or R7s.

I would think that someone going from an R7 to a NT01 would be very disappointed I love the NT01 as a DE tire, but it does not have the grip the Hoosiers have.

BFG R1 is a very nice tire. They won't have the grip of a sticker Hoosier, but they are good to race out to 15HC's, and usable after that. I ran them for quite a few years on my 996. Never ever got to the cord. Just tossed them after they were cycled out.

what about the toyos we run in SPC? A good dry tire and reasonably priced

Be a great practice tire

My track car is a Cayman R (not the 993 turbo in the avatar) with 18 inch wheels and there are not many tires that have the correct front/rear diameter ratios to keep the ABS happy. It pretty much comes down to R7s, Z214s, NT01s and Toyo R888s. In my experience, there isn't a significant difference between NT01s and R888s and they are a few seconds slower than R7s and Z214s. I usually use R7s but due to the warnings from Hoosier about banked tracks, I was interested in substituting the Z214s but it sounds like the issues are the same. Going with the Nittos or Toyos( even though the class rules would allow me to take weight off my car to offset the difference in grip compared to the Hoosiers and Hankooks ) would be a big difference in lap time. However, it looks like those are the only options.

Nothing in 18"...

Toyo RR is a really good tire
