I'm looking for a single tyre to match the other four on the car - Bridgestone Duelers .  However, Bridgestone now say the tyre model I need is being discontinued. I eventually tracked one down on the 'internet in a rather obscure place, but the tyre is new.  The tyre DOT is 48/18.  I'd intended to use the tyre as part of a 5 pattern wheel rotation system.  Current tyres are 43/19.  Any thoughts? 

No problem at all.

Yeah, I was coming to that conclusion, but then thought about other issues.  The tyres are being sold by a 'trading' company down in Bedford.  I looked on their website and they mainly sell stuff like boxes of crisps, cooker cleaning fluid and cheesy wootsits   So, I was wondering how these tyres have been stored since 2018.  On top of a cupboard, under a skylight.  Under tons of Haribos, and the like.  So I'll give it a miss this time.  Thanks for you reply though.  PS I like your Border Terrier (?) photo.

No issues from that, unless you think you'll not wear it out in 6 years.

It wouldn’t worry me.  

Google Michelin for a view on tyre age, I know yours are not Michelin but an interesting article suggesting 10 years for replacement. Lots of ifs and buts of course.

Very good suggestion.  I found this Michelin tyres aren't bananas :)  Now you've got me thinking, as I'd concluded it wasn't worth the risk... ummmmm !
