I replaced my tires on my '03, when I bought it in '11 with 2k miles on it. Dunlop recommended replacing over 6 years old, and that sounded reasonable.
I bought an '07 SG in December with 7k miles on it. The tires looked pretty much like yours do. I replaced the rear when it wore down (roughly at 11k). Never had any issues. The front is still on there and going strong. Had it inspected during service and everything is ok. no issues. Same style tires you are looking at there. If you're paranoid about tires, then replace them, if you ride dangerously aggressively then I would probably replace also. Otherwise I think you would be ok.
When I was vintage bike racing there was a guy using tires from 10 years prior - he was fast as heck; the tires on my 73 vette were 15 years old and were fine... they seem to lose their wet grip sooner than dry grip so be careful in the rain. so even if the lawyers say replace after 5 years, if you know your bike you will know when they aren't performing well.
My experience with car racing is older tires are fine IF you get lots of heat into the them, minimum 3 laps. They soften up and you use them till they show cord. However they are TERRIBLE in cool weather and rain. Same principle applies to street tires. Tires start hardening as soon as they come out of the mold. Every additional heat cycle accelerates that. I change my car and bike tires every 5 years along with the battery. Peace of mind on that cool, wet fall day. Just dig your fingernail into a new tire at the stealership and your older tire.
If you are thinking your tires are maybe not in very good condition by all means buy a new set. This is not something to think.... (maybe I can get that next trip out of them). You only have 2 and and why worry about it. Replace and RIDE!
Tires start to lose grip 2 years after date of mfg. I'd never go more than 4 years on a tire from date of mfg on a cruiser, 2 years on a sport bike.
You'll find the the date stamp on the side wall. it's a 4 digit stamp. First 2 numbers are the week, second 2 are the year. So a code 1012 would be the 10th week of 2012.
lol OK OK point taken gentlemen.
No bike inspection required around these parts.
Took some pictures, don't look so bad to me but understood the rubber won't be nearly as quality now. Unless I can't read tires very well?
Will likely ride out the rest of the season carefully then pick up some new rubber in the spring.
Thanks!
It's a tire...nothing metaphysical about 5 years...I had a tire in my shop in Tn for a decade...put it on my 98 Fatboy...got 15k miles out of it. If it looks good, it will give you decent service as long as it was a quality tire to begin with.
I support the change camp! I certainly wouldn't ride on them, except to get the bike home, they would go along with all the fluids, as part of the process of making the 'new' bike mine.
There are too many variables that can't realistically be summed up to come up with one answer to how many years is a tire good for. There are some rough guidelines from the mfg but the tires on a bike that lives outdoors in the desert heat will have a very different lifespan than a bike stored inside in a more moderate environment.
Me personally, I would base my decision on a visual inspection, your usage and the value for the piece of mind.
Old tires crack and get hard hurting traction and comfort. Take a look at the side walls, if you see any cracks, get rid of then. My experiense is that over 5 years, motorcycle tires are done, too old.
