I feel like anytime I have a question, at least 2 other people have already posted something similar in the last week, so sorry for the repetitive stuff.

I've got an 86 with very low miles that I picked up from the second owner.  He bought it from a neighbor down the street who had bought it for his wife, who pretty much never rode it.  The 2nd owner had done some carb work, but I don't remember him saying whether he had replaced the tires or if the 1st owner had replaced them before selling the bike.  I'm currently around 3000 miles, with the last 1300 coming from me.  The front tire treads are looking a little worn - pretty evenly, though and there's a bit less than 1/4 inch of tread depth.  There is some cracking along the side and in some of the treads.  I've tried to get some pictures, but the cracks aren't showing up very clearly.  The rear tire looks much better - lots of tread depth left and very minimal cracking along the side.  Both tires are IRC.  I tried to find markings that would indicate manufacturing date, but really wasn't sure what I'm looking for.

Here are several pics.  I've got some tax return money coming that I'm either going to use to get new tires, or do some other cosmetic/performance upgrades.  Do I need new tires?  Do I just need a new front tire?  Or should they last me a while yet?

As always, the help is greatly appreciated.  

Front tire:






Rear tire:

I have seen dry rotting on the sidewalls. This is usually caused by armor all or similar tire glosses. When you stop using the product the sidewalls will dry out.
Because there are cracks in between the tread I would suggest replacing the front tire.
I just had the same problems with my tires and changed them.
Just my opinion

Somewhere on the tire is a date code, but with only 3k miles, they might be original.

Think about it,  24 year old tires.......  Going 65 down the highway.....  NOT me.

Please replace them..... safety first!!!!

EDIT: I would recommend not buying the origianl IRC brand tires.    You can do soo much better.

Little,

Please post the date the tires were manufactured.

Based on the pics alone, that tire looks good.  Need to know how old it is, though.

From Wikipedia:

The DOT Code begins with the letters "DOT" followed by a plant code (two numbers or letters) that identifies where it was manufactured. The last four numbers represent the week and year the tire was built. A three-digit code was used for tires manufactured before the year 2000. For example, 178 means it was manufactured in the 17th week of 8th year of the decade. In this case it means 1988. For tires manufactured in the 1990s, the same code holds true, but there is a little triangle (Δ) after the DOT code. Thus, a tire manufactured in the 17th week of 1998 would have the code 178Δ. In 2000, the code was switched to a 4-digit code. Same rules apply, so for example, 3003 means the tire was manufactured in the 30th week of 2003.

Something tells me you've got the original rubber on that 1986 machine.  If it were me, I would not ride that bike another inch until it had new tires.

But, that's just me......please be careful!
