i use kumho kl71's i have 35x 12.50 they stand at aprox 34 inches tall... i have not balanced them and have no need to as they perform faultlessly, as did the 33's that i had before that covered aprox 80,000 miles.
i have used the cooper stt's and to be honest find them horrible, they hold stones and clog with mud. more worryingly they dont seem to stop any ware near as well as the kumho's. we have a set of stt's on my girlfriends truck and the side walls are deteriorating terrible and will be replaced with kumhos asap!
the hankook RT03 is allso an excellent tyre...
