Get a Maxxis 2.5 or any 2.3 tire you like and enjoy. A 2.7 or even a true 2.5 is a bad idea. Wheels go out of true, it's a fact and if you want to keep riding when this happens than this is your best. Sorry, I know your pain I had one of those Jr.T's with crappy tire clearence. That's why I bought a Boxxer and then a Monster T, no more tire clearence issues. Good luck.
