any truth to this idea about flat tires??

I don't have any hard evidence to support that contention but logic tells me that a stronger tire (Z-rated) will hold up better than a tire rated for lower speeds.

I suppose manufacturer quality standards are a factor (think Firestone Wilderness and ATX tires) as is usage. Consistant high speeds on a 112 mph-rated tire would probably stress it more than it would on a 150 mph-rated tire, thus leading to possible frequent blowouts.

I've always had V or Z-rated tires on my Mustang and have never had a blowout and only one flat in 12 years.
