The stock tires on our 09 Sahara have lasted almost 5000 miles now and haven't had any problems.
Funny thing about the Rubicon though! Although it was brand new and on the show room floor, I didn't notice how bad the tires were until I got it home.
Immediately had to make allowances for new tires and wheels. Got it all done just before they were about to blow! Now I've got all these wheels to git rid of but, no blowouts!!! Except the check book!
There's usually mud on it or rocks under it!
Welcome, and have fun with your Sahara!!!
