Just got a 2wd 4.0 Ranger, in good shape but the factory 225 70 14 are...lets say there's lots of room for improvement. would like to get some '01 15 inch Explorer "swirlies" and go with a small lift and 235 70 15. Factory 3:55 on a 4 speed auto. Likely go up to 4:10 and adjust the vss for the tire change as well. Any of you guys know of any pitfalls I'll run into if I did this?
