For instance 4512 would mean the 45 week of 2012 (see picture). Because of the supply chain and transit times most tires at best will be 9-10 months old when you buy them. On the track you presumably will be pushing the bike and your skills to the limit. Why handicap yourself or set yourself up for an accident by using old hard rubber at the track.

Same goes for Condoms!

Thank you

I think the responses are a bit OTT, but I did ask for your opinions so thanks anyway...I must admit I actually have first hand experience of using old tyres (blue or otherwise), and have never had a problem, but I wanted to see the level of responses and you guys didn't disappoint

Obviously, you would not be trying to push for a lap time, unless you were experienced to understand the feedback of a worn tyre like say dricked, but neither would it be as bad as sticking your dick in a blender (unless you like that kind of thing).

Anyway...I take onboard what you lot are saying but I may just go new front...Old rear.

Like I said, just setting the bike up (geometry), so will be going around, not trying to blaze a trail.

evallarta thanks for the advice about the compliancy of the rubber, I can use that.

Thanks anyway guys

I've used blue tires many times. They are nowhere near as good as fresh new rubber but at the time I couldn't really tell the difference and if your "not that fast" you probably won't either. I noticed there was less edge grip with that 5 year old tire but really it wasn't terrible. That tire sat mounted in my unheated garage that whole time too :)

Well at least mine aren't mounted so hopefully profile hasn't been affected by bike standing and causing a flat spot.

Be good to see how well the TC works on the bike with the used rear...If it activates at all...I want to try to activate it at some point....Have done so from a hard standing start, but would like to see how it stacks up coming out of a corner.

Anyway, like I said I am going to mount the new front and then get a few laps in then mount the new rear probably on another occasion when I'm more confident with the set up.

Thanks for the insight.
