I am going to buy a new set of Michelin Super Sports for my 11 GS in the next couple of weeks.

I would think that there is not a huge demand for the 345-30-19 rears and don't want to buy some that have been setting in a warehouse too long.

What is an acceptable date time frame from date of manufacture to install date so that I don't end up with old tires before the tread is gone, like the GY F1's that are original tires and very hard and not responsive

I am hoping to get 2-3 years out of the tires and about 25K Miles from them.

I bought the same exact tires in that size this past summer. They were only a couple months old. I wouldn't worry. Just buy and enjoy. You'll love those tires. They're much better than the Goodyear's.

I buy a lot of superbike tires and wouldn't buy any, for my bike or car, that were over three years old. There's no telling how long they may have sat in the sun in someone's tire shop instead of a nice cool dark warehouse.

I personally would not accept the tires if the date stamp was more than a year old. Your local dealer probably will not have them in stock and have to order them. Chances are good that you will get recent manufacture tires.

Thanks for your reply's guys

I bought the SS ZPs for my 11 GS last fall and all four tires were no more than a few months old according to the date codes. Because of the sizes our GS take they are always in short supply so I would expect that you would get tires that were only a few months old at most. Enjoy the new ride.

Also keep in mind, if you see them on sale for a great price, ask for the date code... They almost got me, I paid a little more for new tires and am happy with my decision

I bought my 2012 GS this past Sep 14. The dealer had already installed new tires all around. The fronts were manufactured in 2014, the rears 2011. Should be ok. Free is good...

6 months old is my limit. Most of my tires time out due to age and not tire wear so getting new recently manufactured tires is a top priority when I re-shoe a vehicle. Put a set of new Michelin XD2's on my F-550 yesterday that were built late 2014, 444. 44th week of 2014.

The experts usually put it at no older then 5 years from what I've heard and read.

Whether the tires have been sitting in a cool, dark warehouse will age and dry-rot. Even if they look like brand new, a tire that is more than 5 years old from manufacture date should not be in use.

So in reality if you only get a year out of your tires, if the date is 3 years old, they would still work fine and be safe, but if you buy a tire and find was more than a year since manufactured you can request it be replace.

Did your GS come with 345s? Mine are 325s.

The original GY F1's are 325. The 345's will fit with no issues i'm told

Like to see how the 345's look after you get them. I am thinking you may be able to see a little width increase with hardly no noticeable increase in height. What are you thinking about the fronts?
