BSD, If you want to claim you source your info from the manufacturer, at least get the right one. Try Goodyear. Or actually, since most of them are retreads, try whoever does that. In ML at least, that's still Goodyear.
The tyres "axle mate" is better off supporting it's blown mate when the a/c is 2.5 to 3 tonnes less in landing weight, and cold, rather that pretty much right after take off. (Heavier a/c and much hotter) As long as the gear retracts normally, and no other sytems are an issue, then going to Bn isn't an issue.
