In preparation for the upcoming HPDE season, I have been going through the tires in my shop to see what still has some useful life.

I have almost 40 tires, not counting the ones on my two cars, a little bit of everything.

Street: Goodyear Runflats, Michelin Pilot Sport Cups, and Nitto NT01s.

Track: Hossier R6s and A6s, and Goodyear RS3s.

As a result of my mediocre tire management, I do not have many matched sets.

My Question: Would it be reasonable to mix R6 / A6, or with a Goodyear RS3?

I understand the different properties of the tires, but I am only a "week-end warrior" looking to get a few extra track days out of my supply. I have been spending almost $400. per week-end on tires, so I am just trying to get a handle on my operating costs.

My flame suit is on, do what do you think?

I'll step in before everyone says no .

For hpde if you have some experience with car control I would go for it. Just be aware of which tires are on which wheels so you can have some idea of what the handling characteristics will be and how they might change front to rear over a session or day. For example, I was doing a track day in Reno/Fernley several years ago on scrub dunlop slicks and corded the front tires in the morning. I figured they would last all weekend so I was screwed until another guy told me he just dumped 2 NT01's in a dumpster in Reno and they still had some life in them. So I went and mounted the NT01's on my front wheels and kept the slicks in the back and had a great weekend. In general, I would mount the stickier tires in back since a slight push will be safer than a sudden spin.

+1. I used to drive w/GY supercars in front and Nitto R-II in rear on my C4 and then the C5. Just go w/the stickier tire on the rear for safety and you are good to go. Don't expect much getter lap times then you'd get w/the front type tire.

I do it all the time. Just know which axle has less grip and make sure the stickier tires of the set go there. I would suggest a durometer unless you have a good knowledge of tires. Treadwear numbers are not uniform across brands.

I did it with several types of tires.

It all depends on your experience level, but as a rule of thumb I always told my students to never mix & match tires. There are way too many things to focus on and worrying about differing levels of grip per corner is something a true novice shouldn't have to do.

I would also give the same advice to students. Since I am an advanced level driver, and instruct for six different groups, and know my cars capabilities very well, I feel pretty comfortable with managing the various grip levels. Also, I wouldn't even consider mixing any type of street tires with R comps.

Thanks for the input.

I've seen an A6, R6, and V710 on your car at the same time

And some with only 9psi in them.
