Cooper Discoverer STT

I was wondering if anyone had a set of 35x12.50R15 Cooper Discoverer STT's mounted up. I am curious about their "true" size (do they really measure 34.8" that they spec out at on Cooper's website) and how do you like them?

I read through the review page, but no one addressed their actual size. I expect and will be happy with anything 34.5" and above, but below that, I will look at another tire. If you could measure them from the "9 to 3" position while mounted that would be great.

I measured my spare. It's never been used. On an 8" rim with 36 psi it measured 34.71. They seem to pull good. Haven't had a chance to go play since I bought them. On the road imo for as aggressive as they look they're pretty quiet.

Loved the 33x12.50s I had on a 07 f150. Quiet for a mudder and wore great. Also very reasonable compared to similar tires. Will probably replace my MTZs when they're done
