Hello and welcome
When I bought my zed, it has Toyo all round. The front ones were close to limit 1.8mm ish last month and rear still have around 4-5mm left. Wanted to swap all to MPSS but wallet wasn't too happy with my decision as I have to replace my faulty ABS unit. Ended up buying a part worn Kumho front tyres from fellow member. Grip wise, they are a little less compared to Toyo IMO, but for £70 fitted, I'm OK with it for now and hopefully when my wallet is a bit more loaded, i will swap all corner with MPSS.
