Fake Off-Road

I purchased a completed set of these less than a year ago for my older pickup used mainly for dumping trash and launching jon boat. First time the truck went 'off -road' (if you'd even call it that) while riding through wooded trail behind house, one of the tires got punctured when driving over a fallen branch. The puncture is too close to the sidewall, so I can't get it repaired. Forced to purchase a whole new tire, even though these are practically brand new (200-300 miles). I think the tire looks good and seems to ride fine on pavement. However, I would advise staying away if you're wanting an actual decent off road tire. If you're just wanting something that looks good on the road, but doesn't really perform in the realm they're marketed for... these are for you.
