I got my WTB Weirwolf 29x2.55 LT fitted at the weekend at long last.
These are my initial observations, I have only ridden it for about a mile on road and played around on it in the street.
The tyre is big, definitely the biggest 29er you can get at the moment. It fits easily into the Nimbus II 29er frame. It doesn’t have an aggressive tread, the LT means “low tread”. It is bigger than the Bontrager Jones XC 29 (middle in pic) that it replaced, bigger than my Maxxis Holy Roller 24x2.4 (left in pic), and bigger than the Big Apple by a few millimeters all round.
On the road it is very easy and predictable when cornering and gives a very smooth ride. I tried low pressure and medium pressure but I didn’t pump it up hard. With it being such a big tyre even at high pressure you can get a cushioned ride. You can also get some bounce if you like hopping around but I didn’t notice it bouncing along during normal riding. It it did suffer from curb crawl and tried to ride down the crown of the road, but not as bad as knobbly tyres I have tried. It didn’t noticably improve at higher pressure. It may be possible to eliminate kerb crawl by having the tyre really hard but you’d need a lot of pressure in a tyre this big.
This tyre replaced my Bontrager Jones 29x2.25 tyre. Which for some reason tracks straight and true whatever the camber, however it is bad at cornering. Whereas the Weiwolf is the opposite and turns beautifully but doesn’t handle a camber. It probably makes sense that there is a pay-off, and you can’t seem to get a tyre that is good at both, but comparing the two tyres which have very similar tread pattern and profile I can’t think of any reason for this.
If you want a really impressive-looking, large volume, 29" xc tyre that’s nimble on the road the Weirwolf is a great tyre. If you have a problem with severely cambered roads where you live the Bonty is better.
