Disadvantages to bigger tires??

I am currently running an automatic 2008 JK Sahara Wrangler with 2.5" Rough Country lift, 2" wheel spacers, and stock Sahara wheels/tires.

I want to get Nitto Trail Grapplers 295/70R18. Will I be okay with just going through with the regular procedure of buying new tires(mounting and balancing)? I have read up about a lot of talk that I should change the gear ratio (so expensive!) or should consider getting a superchip or something to change the computer settings for bigger tires.

Need some suggestions on what to do here...can I just put these tires on, balance them, and be okay?

What would be best? What would be cheapest?

Thank you!

Those tires are extremely heavy, and on 18" wheels you're going to destroy your fuel economy, acceleraton, braking, etc. It'll also be very hard on axle shafts, lug studs, u-joints, ball joints, transmission parts, etc. I'm not saying that you're going to have problems...but yes there are disadvantages to running big heavy tires like that.

Changing gear ratio will help. You also won't make those fit on the factory wheels so look into some different wheels too.

I have 2" wheel spacers on as well, so they will work. Sorry I forgot to mention that.
