Thanks Beeza,might be more  than a couple mm,i think i"ll just cop it on the chin and go for a180 and try selling the 200.thanks again.

sorry doesn't help you but good to know the metz is wider, I've got the 200-55-18 avon now and have plenty of clearance so I'll go a metz next.

How much do you want for the Metz? pm me if you want.
