They are 7.50R16 nylon ply Dunlop Hi-Miler Custom Xtra-Grips, same as I have on my Series.

I suggest you don't want them, unless you are already deaf, or want to sound fully sik bro but can't afford both tyres and exhaust. From about 30km/h, they start to moan with a wubwubwubwubwub as the bars hit the ground. At least at higher speeds it blends into one constant whirrr. Mud tyres have nothing on the volume of these beasties.
My set were around $110 each second hand from the army, one still has the camo paint from being taken off an RFSV or LRPV or similar :)
I wish i'd put them on 110 rims instead of Series rims, just to give them a try on the County :evil:
