I have a 97 dakota, 4wd, 5.2 v8 and i wanted to put a 6" lift in it, what size tires would be good. Its gonna be mostly an offroad vehicle

 

With that size of lift I'd go 33's or 35's. Stock size is 31's for a 4x4.

Most members have 33's if they have a lift., but there is a member named Blaze who has 35's on his Dak which has 5.5 inches of lift I believe. Looks good but anythng bigger would look silly imo.

 

If you're going to use it off-road, go with 33s. 35s will hit the fenders when it flexes (unless you also have a body lift).
