Title: Track day tire usage
Post by: Justin on March 08, 2009, 10:41:44 PM
I was online and noticed a few 'track tire specials'
"two rears and a front"
Is anyone switching out the front with every other rear swap?

I toss them both and start fresh. . .
curious if you do the same.

On my RC I could have probably gotten 1 front to every two rear but always changed them in pairs just be safe. It always made sense to me that tires were alot cheaper than new bodywork and or parts.

That's part of the Great Tire Conspiracy.

- sell you warmers and a generator because of "cold tires" and "heat cycling"
- sell you more tires before your current  tires are worn, because of "heat cycling"
- sell you a pair of tires because "they should be replaced as a set"

Horse droppings! Cow flop!

Replace a tire when it is worn out or when it loses grip.

My 600 still has the same front I put on it before Miller and it has many, many days left in it. I'll probably go 3:1 for a ratio of rears to fronts.

Here's a tip: Get a Michelin S1246A front and you'll need 1-2 per year and you'll probably think it's the best tire you've ever ridden on.

Well there ya go. That should put an end to the questions about tires!

I agree with what others have said. I go through 2 or 3 rears for each front. I'm running Dunlop GP-A tires on a 2001 Honda 600. I usually replace the front when I feel "guilty" about keeping it on there so long. I usually replace it after about 10 trackdays.

Heretic! You probably don't even have tire warmers, do you?

I am part of the deaf, dumb and gullible crowd that replaces both front and rear at the same time. Oh, and I even have tire warmers! I must be REALLY stupid!  :D

I also replace both at every interval, usually 2-3k miles and they are cheater slicks at that point, but I agree with the statement, when they are worn out and lose grip, CHANGE them..

or really fast

Hopefully you give your fronts to those poor, less fortunate souls who wait every third rear to replace the front.

The no nonsense 'straight talk' is much appreciated. Thanks everyone

I actually usually sell them as a set of good take offs. I have been known to give them away at times though.

Wouldn't hurt my feelings to pick up some of those, I'm too broke to buy new tires...

My point exactly. You are replacing good tires. They are still good for trackday riders who aren't in danger of coming close to record lap times.

Point taken. I was just being a smart ass. It's the way I am, just hard to express through a forum sometimes I guess. No need to defend yourself. Don't mind me.

Also, I just realized this is a thread about track days, but it's in the racers section. Different contexts. I was of course talking about track day riding not racing.

I blame the pink baby-doll shirt wearing thread starter.

!!!!!! HEY  !!!!!!!
Pink was the new black. . . So really it was a black baby doll shirt I had on. It was more of a midriff, really

It's better to ask an amateur racer about tires, because you push limits more than I do.
I don't want to ask less experienced or more conservative riders for advice on traction.

I checked and the front tire on my GSXR has about 1000 miles on it. Brand new, then 420-430 miles at Miller in half-hour sessions, the rest at Fernley in 20-30 minute sessions. Works out to 60-70 heat cycles. Soon to be making a sketchy inside pass at a track near you!   ;)

Well what about shinko tires?
they are very good tires and a lot of dragracers swear by them. and the best part is that for the cost of a rear tire of a big name brand tire you can get a set of the Shikos.
check out their site.

the 003 tires would be a good bet as well as the 008's

How much throttle do the drag racers apply while leaned over? How hard do they trail brake into bumpy corners?

They may be "very good tires" for drag racing, but there is little evidence to support they are worthy of track riding. Get thee to Google.

Ive read reviews on the Shinko slicks as I was going to purchase a set because the price is right. The reviews are NOT GOOD. They are hard even in the soft compound. A lot of the super moto guys said they have crashed because of these tires. I decided not to buy them..

I finally retired my front Michelin S1246A slick from my GSX-R600. Brand new before Miller last year, rode there and Fernley. Seen 104 F ambient temperature maximum, 29 F minimum, while out on the track, and ridden in light rain on a damp track. Stored for six months. Never used with a tire warmer or cover.

1,621 miles
12 days
84 sessions (heat cycles)

The wear dimples are only half worn but it developed a gutter near its edges.

Amortized over the life of the tire, the $180 or so it will cost you from SPL is peanuts.
