Bicycle Mechanics - WTB tires

Do you like this brand of tires?

I have a set on my bike, they're 41/40? what ever that means.

I think they're OK, but the shape of the tire is very flat........ :D

WTB Enduroraptor / Velociraptor tires are a great all around XC and snow tires, IMHO.

Try some air in the tire to take care of the 'flat' shape ;)

Wilderness Trail Bikes' Global Measuring System

From the WTB Website - via Sheldon Brown's website:

GMS Global Measuring System The current industry standard for specifying the actual inflated size of a bicycle tire does not account for subtle variation in tread and casing size. To address this problem and provide you with more information for comparing tires, WTB has introduced the Global Measuring System (GMS) for tire measurement.
The GMS uses a two-number system: the first number is the width of the casing, and the second number is the width of the tread, both in millimeters. These measurements are taken on a rim which is 20mm wide at the bead-capturing point, with a tire inflated to 60psi and maintained for 24 hours.

In addition to being able to accurately size a tire, knowing the actual casing size and tread width provides an indication of air volume, tread characteristics and tread contact area; all of which provide you with a more concise idea of what ride characteristics to expect from each of WTB's tires.

The WTBs are good ATB tires, a little on the heavy side, in general, but they have been pretty good to me before. Anything skinnier than 2.1 would be better for the snow, 1.9 or even 1.5 with studs work well in the snow.

I have the WTB nanoraptors 2.1.. They are good and fast on dry, hard, rough terrain. But they are not so good in muddy conditions as compared to the eduro's, but is still good.

I use a Velocoraptor on the front. I love the traction it gives me on fast fire road descents. It is also great in mud.

I have used on on the rear before. It is a great climber but slippery side to side in the wet.

VERY agressive tread.
