30x9.50's on 15 inch rims gains you 1 inch. stock height is about little over 27" and 30's are almost 30" so if you subtract the 2 you have about 2.5 inches. BUT thats 1.25 on the top and bottom of the rim. so you only gain an inch.

But an inch and more aggressive tires is a big help! <img src="/forums/images/graemlins/cheers.gif" alt="" />
