Stolen from http://www.metrics.com/vw/faq/tires.html (referenced in a
H= Speed Rated Code
(H means it is rated for speeds up to 240 Km/hr or KPH for short
periods of time. The Michelin brochure adds that the tires must be normally
loaded and properly inflated as well.)
P=150, Q=160,R=170,S=180,T=190,U=200,H=210,V=240,Z>240 km/h
(Americans can multiply by .6214 to get mph and round it off)
Just curious, but for the same model tire and size, what manufacturing
differences are there between, say, an H-rating and a V-rating? Which
of the extra improvements in V-rated tires benefit handling at speeds
below 150 mph? Will that $10-20 extra get me better steering response,
linear (predictable) breakaway, etc.?
