The Beast of the East came standard with WTB Bridger 3.0" tyres, they stand up to there quoted width but are not the best in slippery mud and drag too much in the dry. The other down side is they are not the lightest for a folding tyre.
Many manufacturers are now designing and bringing out 27.5"+ tyres with Schwalbe quick off the mark compared to when they released their 26 x 4/5" Jumbo Jims which are still very hard to get hold of.
They have two models - Nobby Nic & Rocket Ron in both 2.8" & 3.0" and in two different side wall options - SnakeSkin or LiteSkin. At the mo there only seems to be the SnakeSkin options available in the UK.
Here is a LINK to the Schwalbe guff and here is a link to the Nobby Nic Tech Info and the Rocket Ron Tech Info
Claimed weight 910g, mine weighted in at 890g so not bad then. I will feed back more of a review after more miles of running this rubber but first impressions are good, just like the Jumbo Jim which I have been running for a while with nothing negative at all to report.
The rrp is £56.99, Ison Distribution has stock so any LBS with an account with them will be able to order them for you. Charlie the Bikemonger has also got then for £60.
I must admit I found them by accident on Merlin Cycles and paid £28.66 with the Top Cash Back off, that's less than half price, now that's what I call good value for money.
