I have also imported 275/55R20s (waiting for the 20" Rims expected to arrive next month for my Hilux & 225/55R17s for our Altis.
The issue is, that here, either you get old tyres sold as new or manufacturing date tempered tyres sold as new. In Isb/Rwp, GawalMandi is hub of all such nefarious activities.
These tyres are atleast brand new. That's why I want to sell the Michelins and keep the CatchPowers for the Hilux (both 17"s as well as 20") and have already replaced my Altis 215/45R17s with the BCT 225/55R17s.
