Which Tyres?

only 1 gumwall Jack Brown in stock if that matters?

Hypers definitely. They do size up big though. Mine are the 35s but come up almost 38 on 21 internal rims even with low pressure. They do say 37-622 on the side which is a bit confusing. Would have got 32s if I'd known.

Also dont expect to be able to have black tyres by removing the reflective strip. Removed mine last night and leaves a light grey strip in its place, may go black with riding but bit annoying
