I have a heavy foot and usually drive 80mph on most highways but do the speed limits in town. Many times, I will drive faster than 80mph. These tires are my 2nd set. I love them. They are extra-ordinarily fabulous. There are no other tires like them. These tires ought to be standard on all vehicles including trucks. If only I could get them on my 2011 toyota tacoma in a 265/65r17. I've traveled from my home state of Indiana to Montana, Utah, Colorado, South Dakota, Florida, South Carolina and many other states during mostly the summer time and some during the winter and would not even think about driving there without these tires. I've got them inflated with nitrogen. I've found that the most common reason why many tires do not perform nor last as long as they should due to over-inflation and under-inflation as well. Nitrogen keeps them at proper factory specs. I've witnessed that oil change businesses as well as tire shops and car dealerships will over-inflate your tires. The correct tire pressure is located on the inside of the driver's door. Although I tell these places not to touch my tire pressures, they still do and many times have found my tires over-inflated to their maximum which will make them ride rough, be unresponsive, and will wear out many times faster. These michelin pilot tires are simply put...the best of the best of the best. There are no other tires like them and no other tires will come close to them. I corner fast, brake hard, slide around corners on gravel roads plus I drive fast in wet or snowy or dry conditions. Knocking on wood, I've yet to feel them hydroplane. I suggest buying only these tires and carrying a tire pressure gauge and check them for proper air pressure at least monthly. I've yet to add any additional nitrogen in 45000 miles.
