20" tire size question

[Bryan E 2]

If I picked up a set of 20"rims, what is the biggest size tire I can put on an 01 sport trac? Thanks in advance!

Well it's going to depend on offset, rim width, whether or not you have a body lift/torsion twist, and how much trimming you're doing. I know my 15"s have 33" tires and 4.75 backspacing at -12 offset and I get zero rubbing with a BL/TT. Hugh has 35's on a similar setup and only had to do minor trimming. If you have 3.73 gears I wouldn't go bigger than 33's or you'll destroy your transmission and fuel economy. 4.10s might get away with 35s but mileage would be bad. Anything bigger consider regearing.

stock ride height, guy has a set of 20's on craigslist he had on a ranger and was wondering what size tire I could get as the ones on there will probably need replaced soon. May be able to score them cheap (I know tires are stupid expensive for 20's)

These are the rims/tires

20"s may look cool, but on a gen1 with torsion bars front and leaf spring rear. It will ride rough. I wouldnt go over 18" with a 265-60 tire. That is what I run @ stock ride hieght. Wheels are 18x9 with 0 offset.
