What is the widest tire I can run???

82 LWB with 15X10 4.5" backspacing. Currently I run a 295 50 15, but don't like how low profile they are... I would like to go back to 29 or 30 inches tall. What is the widest tire you can run without having to reloacate leafs or pound out the wheel wells?!!

THANKS!

are your rims 15x10's? That sounds mighty wide for an 8" rim!
