Need help finding right tire size for a 3in lift kit

[bigcountry2807]

I need help. Going to be having a 3in lift kit from RoughCountry installed on my 1998 Suburban. Want to go to bigger tires without doing any modifications except the lift kit. I am thinking that i may need to go wider as well for better stability. Please help.

Also this is the first vehicle I have had with push button 4wd. Is it on the fly or not, and what does the Auto4WD do? Don't want to push it until I know.

the best resource to learn how to use your 4wd is the owners manual. If you dont have a hard copy here is a downloadable copy

Concerning the tires, measure the existing tire clearance. In the front take the measurements with the wheels fully turned. Stock width appears to be 235 but remember you will effect your speedometer and transmission shifting if you increase diameter by more than 1".
