How many sets of tires do you typically buy in a year?

Slicer?

Definitely can fit that tire size in rear (not in front). Plus a 275 is great on a 10.5. Honestly wouldn't want it on anything narrower for track use. That size tire is used routinely by people running ZCP wheels (10" wide).

Why the arbitrary $1000 limit? Every tire on that list is mediocre.

I think it's better to look at longevity as part of your cost. In other words, what's cheaper? A tire that costs $1000 but only lasts one track day or a set of tires that runs $1500 but lasts two?

It a good point.
But all my tires last short of two days and more than one day.

For what I want to experiment with in the first few 2020 track days a mediocre tire will do.

If want to go fast it would be the Hoosier R7 or A7. For that, I already felt the difference. Nothing else came close to the 265/35/19 R7 on the front.

He's a bit unconventional.

Do you have access to a set up engineer? Something seems wrong for you to get such short life. I regularly get 8-10 days from a set of tires. I run 3-4 sessions a day, 10-20 minutes per session. I push the car fairly hard. Heck I still have a set of R7's from 2017 that still are in good shape.

This, he thinks all tyres will wear the same with a given alignment. Hence he doesn't want to pay for what he usually uses.

I run 7 x 20min session per day at NYST
I don't think LRP is as abrasive as NYST

I would really feel like I am wasting my money if I don't get performance I need from the tires I paid for...

To keep things in perspective:
Either track , LRP to the east, NYST to the west is 70 minutes from my house.

I get up in the morning, after coffee at 6am, I am at the track before 8am, empty the car, 8:30 driver meeting, 9am-5pm I do 7x20min session and I am home for dinner.

Meaning, a track day for me is not a major time commitment aside from the actual time on the track.

I feel free to experiment with ideas, knowing that I will not make my best lap time that day.

I suppose I disagree that you don't learn anything doing 1:40 at NYST on sub $1000 a tire set. I do agree that at 1:50 pace it does not translate into what happens at 1:35.

But at 1:38-1:40 it is relevant enough.

About alignment and suspension. My experience showed that the camber of 265/35 on expensive R7, from a wear point, is similar enough to a ECSTA PS91 265/35 or 275/30.

So I think a reasonable approach given my objectives and circumstances is to adjust my settings using a less expensive tire before I use expensive tires.

What I have proven, to myself, is that while slick 235/35 is faster than any of the high performance 265-275, the alignment is not the same.

This creates a practical choice, do I align the car two different ways? or do I align the car to the 265-275 tires and alternate between expensive R7 and Inexpensive summer tire.

And I came to the realization that I will keep the alignment the same, and use less expensive tires.

Lastly, Looking for all the tires I outlined, calling a $900 tire set that gets consumed in two days cheap is a mischaracterization of value. It is a very very expensive hobby.

While I am not by any away advise anyone to follow what I am doing, I will continue to report my lap times and equipment I use. The results are not as obvious to me as to some of you.

Lastly, I would not label me as "different" or "strange" I am as an average person as it gets, alas perhaps with a tinge of curiosity and need to experience things myself to learn. :-)

Comments are always welcomed. Where else can you get such a quick answer to a 275/35 on 10.5 question? only here.

I respect that you're doing what you want to do, but your approach is counter to the approach most others at your level are taking.

You have a car with a supercharger, aero, ceramic brakes, 4-way JRZ's (IIRC) yet run on some of the cheapest tires out there. At your driving level and with the performance of your car, most (and I mean 99.9% of the advanced driver population) would be on R-Comps or true slicks.

As an aside, you should consider springing for a trip to Watkins Glen this year. Best track in North America and not really that far from you.

[m13s]

Putting those tires on that setup is a waste of time and money.

Spend some money on good tires, the sneakers you have mentioned are shit. Sans Bridgestones which are a decent street tire.

Why are you running 19's ?

Moose,

I want to be clear, I am not disagreeing with you or @Deka. I have put a set of hoosier R7 on this setup and that can't be beat. I am not tryin to do 1:35 with less of tires.

Having said that, It does not mean that EVERY TIME I go for a track day I MUST put on a set of expensive tires. In my book I MAY put on a less expensive tires for time to time to feel and explore

For example, If I want experiment with 275/30/19 front and 275/35/19 rear. I will be doing it with the cheapest tires I can find in the max performance summer or ultra perf summer.

Now if we are going into "why do you want to do that, most people don't" well, I don't have an answer for that. I just do want to.

Yes Watkins Glenn is fabulous. Been there with Ducati and my (RIP) 1995 Euro M5. Fabulous but 4 hours away. not going to happen this year. Unless all you guys will be there and I will have to come and meet you guys.


As far as what most people do.... let's not go there. :-)

This


If u went with a 265 u could get AD08s or RE71s, both of which will be wider in a 265 then any of the tires u listed and only cost u an extra $300. That's a no brainer.

I was more referring to his poor choice of tires

$300 is the cost of a full 7x20min track day.
I agree. No brainer.

[Grillpt]

What tires are u using that last short of two days and are u wearing the fronts and the rears out that quickly?

[Bartledoo]

I think we are better off trying to convince him to trade the BBK for a PFC or AP Radi-Cal kit that fits 18" wheels...

I was on Hoosier R7 265/35/19 front.
I don't wear the rear quicky
Th front I chew the outside with -3.0 camber.
For 2020 i will be trying -3.25 or -3.5 front
