What are the biggest tires I can put on my 99 B4000 without having to lift it?

Does anybody know? I really would like to get some new tires soon!

Not sure if this will help but...

If you go to 4wheelparts.com and look up shocks, there will be a link for a tire fitment chart. I found it by clicking on the following tabs: Suspension- Explorerer Pro Comp- Shocks - ES3000 - Tire Fitment. It lists a Ford Ranger up to '96. I'm not sure if this is the same as a '99. It lists the 4X4 version with a suspension lift of 2" allowing a tire height of 31". I would guess without a lift you would get exactly 2" less (?) for a height of 29". It also lists 4X2 if you need those numbers.

Good Luck!

sourceunkn, thanks for the link :D
