not sure what caused this but I just picked these up and wondering if they are still ok to drive on.

Well, you've got some significant chunking going on there. My guess is that these tires were used in a track event or autocross, where they got very hot.

How old are they? (Click here to learn how to tell.) If they're not too old, I would use 'em, no problem...

 

is this it?

Probably not. It's usually molded into an area in the sidewall that's depressed to make it easy for them to change the serial numbers, not numbers that stand out away from the sidewall. And the numbers are usually slightly bigger than that.

It might be on only one sidewall, not both.

Humm this is the other #'s besides the tire size and air pressure

Yup, those are the numbers. The tires were made in 2005. Go ahead and use them, they should be fine.

 

Awesome thanks! I dunno if you can really tell from picture but, how much life do you think is left on them?

 

you can tell from the dot number, where it says DOT xxxx xxxx xxxx the last 4 numbers is the week and the year the tire was made so 2505 would be about halfway into 2005

edit: as for your tires the cracking seems pretty rough but ive seen much worse id say they are ok there seems to be decent tread left just keep an eye on possible camber wear near the cracking

You can't tell from a picture, and tread life varies.

 

dunno,but if i were u i was gonna bye new ones

 

I wouldnt be ridin on those Tires at all, Its the safe-factor when it comes down to this, even if there "newer".

 

I don't think there's anything unsafe with these tires.
