One flat in 65,000 miles with the stock BFG All Terrains...a shard of metal I picked up on a trail. Luckily it caused a slow leak...I didn't even know I had it until the next morning when I walked out of the hotel room. If you go off road frequently I wouldn't go without a spare...especially if you go FAR off-road where a tow truck can't reach.

One other thing to consider...even if you don't go off road, but you go far from home, it's not always easy to find a shop that keeps the OEM BFGs in stock. If I didn't have my spare I'd have been stuck in Flagstaff, Arizona (about 3,000 miles from home) waiting on a tire to be delivered. Lucky me...I discovered my flat on a SUNDAY morning.

Regarding tire carriers...I got rid of my interior carrier and went with an OEM exterior one. No real complaints about the exterior unit. It's great to have the interior room back.
