Used these tires on the 2000km Canning Stock Route in Western Australia known for its harsh environment with sand rock gravel all thrown in they preformed better then expected

Will never buy these again. Tires are less than 7 months old and they are separating. Also have a friend that bought these tires he had had the same issues. Had to have all six replaced with around the same mileage as mine. If fact I got mine after he bought his thinking they were a good deal. My truck had 234,569 miles on it when installed now it has 247,990 so they are of poor construction from my experience

OK, here is the good with the bad.
The good is that they are a decent tire at a great price. They are air pressure sensitive but the ride is good with 45 PSI front and 40 PSI rear for my P/U empty. Note: you must air up to haul a load (80 PSI). I drive about 60% city, 30% highway and 10% off off road (Ca. desert). Tires work very well at the right air pressure in the desert (35-30 PSI). Just returned from a 90 mile off road trip over 2 days and never even hinted of getting stuck (sand & rocks etc).
The bad is that they are very noisy on the road, are cupping a little and are wearing fast. I am guessing they will be worn out at around 30K miles or so. On road handling is only OK. I might buy them again because of the price.
By the way do not ever buy Michelin truck tires. Before the Hifly's I has a set of Michelin LTX tires and 3 out of 4 had bad tread separation on the same trip with 50% tread remaining. After 2 weeks of jumping through hoops with Michelin they voided my warranty saying it was because I had Armor-all on the tires. That's right the excuse was because i had Armor-all on the tires. Went up their chain of command and they all refused to honor the warranty. The tire rep at Allen Tire said Michelin tire never honors a warranty - period.

my opinion on these tires is very good I have just got back from a 5500k trip on some off our toughest roads in sa sand dunes mud rocky you name it and never had any problems at all. very happy I rate them better than the last two setts of cooper tires. cooper tyers will never be seen on any of my cars agan.only because I have had no luck with them at all.
