M=up to 81 mph (130 km/h)
Q=up to 99mph (160km/h)
s=up to 112mph (180km/h)
T=up to 118mph (190km/h)
U=up to 124mph ( 200km/h)
H=up to 130mph (210km/h)
V=up to 149mph (240km/h)
W=up to 168mph (270km/h)
Y=up to 186mph (299km/h)
Z=over 149mph (240km/h)
Side note on that the tires acual capacity may be lower then the rated speed. As far as traction ratings most tires on the market will have a letter rating. For treadwear same most will have a rating of "A" with the exception of a few that will have a "AA" rating. For instance the Kumho Escta Supra 712 has a "AA" tread wear rating.
