Cracking in sidewall

[JEEPRUSTY]

I just got the bike running sweetly again and now my one year old V rated Battleax is showing cracks in the sidewall.

Why does this happen? Another 150 bucks to go.

Is it me or did this not happen as much in old days.

First, are you sure it's one year old?

What's the build date?

If it's that new, I'd be talking to the dealer about how to approach the manufacturer

It happens because rubber dries out. The oil weeps out, and they crack. If you've ever left your bike in the sun for a period of time... take a look at the tires, there'll be a blue tint to the sides of the tread... that's oil coming out.

Do believe there's a date code on tires, think it's 4 digits, first two give the year, second two give the week of the year.

Well, that's not quite right.

Well, that's not quite right.

Don't just say he's wrong (or not quite right) without explaining, Sir!

Well, that's not quite right.

OK, I got it backwards, I'm dyslexic, first two the week and second two the year. If you can watch this video about how to read manufacture date codes to the end you're a better man than me.

Oh great!!... First Avon now Bridgestone. There aren't that many left for my tire size.

Ride more, crack less.

[JEEPRUSTY]

DAMN IT ALL!
It is an 09 tire
only cracked on one side and yet a throwaway

What do you clean your tires with and do you use any tire dressing?

[JEEPRUSTY]

Soap and water
oddly it is the side opposite to the sprocket
Oh well just another day can't take it with you.

The date that the tire was installed is far more important than when the tire was manufactured. Tires not exposed to sunlight (UV) ozone, oil or oxygen can be in new condition for decades.

As long as the cracking does not extend to the cords don't worry. If, however, you can see the cords, even when they are covered with rubber, replace the tire immediately.

Tread and sidewall compounds are typically 30% to 50% oil.

its not really deep and it is only where the names and logos are.

You running wire wheels or cast? If they're cast... I'd spring for new tires... if you've got spokers... well, that's what tubes are for . Give them til the end of the season, and keep it under 75.
