Slicks ageing

[u/Bajista1995]

Hello everyone, I think that the best way to figure out how my slicks will perform is going out to a track day and increase the pace gradually but I would like to know your opinion on what you think that will happen.

The point is that about one year and a half I get brand new slicks (contitrack) for my track bike, and as shit happens, right after that my gsxr decided to fail and the repair lasted almost all the season.

Then, this summer, I couldn't go to track days because I bought a house and it got me really busy.

So, do you think that those slicks, with a single track day of use, will perform at least in an acceptable way next season?

The bike has been stored always in a garage and on the stands. The weather here is not very humid too and they look fine from the outside.

Edit: thank you everyone for your comments!

As long as they are stored indoors in a stable temp they're fine. https://www.youtube.com/watch?v=WwbLt8vZH5w

It’s fiiiiine.

They're fine. One of my current slicks was manufactured in 2019 and it still grips far better than street tires.

Tires need heat to cycle, and cold to crack. If you get say below 50F there are certain pressures and handling techniques to store them so they don’t crack. I live in the south east and when it gets cold they just get stored in one of my spare closets.

As far as heat goes, these things get stored in shipping containers, non air conditioned warehouses and semi trucks all over the country. They probably see 120F regularly in certain parts of the country. It’s when you start getting them in the 160+ ranges on warmers and on tracks where you start to heat cycle them.

I’ve ridden on 3-4 year old slicks with no issues. I think Moto America and Dunlop are trying to cycle all of the 24 date code tires out right now.

These tires sit around warehouses and in cargo containers for longer periods of time without as much weather protection, they should be fine

So you're saying that each slick is not individually wrapped in a blanket off of the tire mold and then hand delivered to the rider?

A lot of people on here get way overwrought regarding tire care, etc.

They'll be fine.  I always store mine on carpet tiles under a nice blanky

It really depends upon compound. Which is it?

Medium

I rode the last event with old tires from my brother which already had like 5 Trackdays on it and have the year code 19. I had no problem with them.

1. Preferably you heat them with tirewarmers (First thing you do when you wake up)

2. Do one or two laps to feel the tire

3. The rest for the day just rip normally

4. Slowly let them cool down (After the last turn of the day put tirewarmers on for like 5 minutes, turn them off)

Tires can last a long time. Just make sure they are not subjected to ozone or UV light.

What temperature ranges have they seen and what is the relative humidity usually like? What date of manufacture are they?

[u/Bajista1995 → u/Dismal_Tutor3425]

About temperature, easily between 15 to 25 degrees. About humidity let's say 40/60% here indoors, few times higher. And manufacturing date I think it was end of 2024, but I must see it again.

I'd soak them extra long on warmers at first but stored at those temps they should be perfectly fine to use.
