For my C6 Z06

- Are there any issues with the 345/35/18 R6's? Currently I'm running the 335 but they are only 30's...and it doesn't appear Hoosier has a 345/30/18. I'm not sure how the 30 to 35 will change things??

- For HPDE days is it necessary to do the initial Heat Cycle on a new set of R6's and then let them sit for a few days? Has anyone compared doing this vs not doing this? Was there a noticeable significant difference?

Thanks for all the help!

No issues with the 345/35/18's, they are commonly run as Z06 rears.

Hey, good seeing you at the track on Sunday at Chuck... I'm runnning those sizes on my Z with zero issues. I ordered mine through Tirerack and for $10 per tire, they were delivered heat cycled. yes you would need to wait 48 hours for proper cycling (as stated on the hoosier site)

Yeah good seeing you out there Mike. I was going to check out your tires before I left but forgot.

You ever run then without the initial heat cycle? I've asked a few people and some said it isn't necessary but others say it helps.

I've never run without a H.C... it's not necessary, but its worth the money because it helps extend the life of the tires.

What do you think the life expectancy is on a set of hoosiers

Bill Dearborn

Hard to say. A lot of it depends on the alignment. Not having sufficient negative camber will ruin the fronts in short order. Running with -1.5 camber you might get 4 weekends out of them if you flip the tires on the rims after the 2nd weekend. If you run -2.5 or -3 then you might get a couple more weekends on them. The other thing you have to consider is the number of heat cycles you will be putting on them. They are sticky for about 3 heat cycles and the really drop off. Still better than street tires but by the time you get 9 or 10 heat cycles they will not be very competitive with newer tires. That is why buying race team take offs is such a bargain. You miss the stickiest portion of the tire's life cycle but you get the remainder for 35% to 45% of the cost of a new tire depending on size.

thanks the heat cycles was exactly what I was asking about.

I'll be running scrub R6 this year for the first time. Will be an interesting learning curve

What size did you decide on or were able to find? My wheels from Finnspeed should be shipping in the next day or so and I started to rethink the hoosier and consider other alternatives. The feedback on heat cycles is so varied its hard to know how long they will be good and how much tires will eat into the budget. I hear anywhere from 12 cycles to around 30 cycles, its hard to separate the fantasy from the reality

are hoosiers that have gone through a few heat cycles and fallen off, still stickier than new R888s? where would you place them on the spectrum of grip vs other R-comps ?



I was going to run CCW C10 + Hoosiers this year but then realized I didn't want to deal with the pain of hooking up a tire trailer, loading, unloading blah blah - given this is the first year running my Z06. I decided to switch to CCW C14 + R888 combination this year and then next year I'll switch to hohos.

Hi Morris I went with the 315s and 345s. No issues at all...except maybe slight rubbing at a full lock which doesn't occur on the track anyway...maybe in a parking lot.

As far as heat cycles you are hearing from 12 - 30 is really the reality. If you are a very fast and aggressive driver you are going to eat through R6 tires in a couple HPDE days. However I see some of the slower and maybe smoother drivers that are maybe running 4+ seconds slower that might get 7 days out of the tires. Really just depends on who and how the car is being driven.

morris

Well that's what I ordered and they are on the way, I figure I might as well go with a new set the first time around to at least know what it is like then I might switch to scrubs here after.

That's a good question. My opinion is that R-comps like the nitto NT-01 provide consistent grip from new to cords. Hoosiers have more grip at first but I would say less grip after many heat cycles. I've been on A6 scrubs that still had good tread but felt less grippy than a good street tire. If you see a lot blue discoloration on a Hoosier you can bet it has been cooked and most of the grip is gone.
