I've had my t6 from new but I put the 18" t5 sportline wheels on after 500 miles with some landsail 235/45/18 tyres. My van hit 7000 miles today and with it coming into winter I thought I'd change the wheels back to the standard 16" as I was changing the wheels over I noticed that both passenger side tyres were pretty much bald on the inside egde. I don't drive the van hard so it has shocked me that after 6500 miles the tyres have deteriorated this much. Anyone else experienced similar?
