As Mike said, I rode through Africa on trelly's! I couldn't recommend 'em enough! Cheap, easy to put on, (even though Grant J might disagree, tee hee hee!) and tougher than John Waynes underpants!
I run them from St Louis, Senegal all the way to Cape Town (west Coast) and only had 1 front and 2 rears changing them in Yaounde, Cameroon. I kept the spare rear till Angola before leaving it as it still had tread!
I initially tried then on the piste in Malaga on a HUMM meet and REALLY enjoyed their grip on the fun stuff. Reasonable for the highway too at 75mph/120+kph with or without luggage and they gave amazing grip on Congos finest highways! (insert; MUD, Mud, Mud!) Obviously they are an off road tyre so on 'damp asphalt' take it easy but that's the same for any similar tyre. The two guys I was riding with went through their tyres like I do
, quick..! Not to mention expensive!
So for the price, if you don't like 'em then no tears will be lost, If named brands are you thing then go ahead but I was adventerous and tried them and came away happy!
Hope it helps?
