Just bought a 2002 XL extended cab and it has the basic tires/rims (235/70R16) and I want something to fill up the wheel wells a little better and dont want to spend too much $$$. Are there any take-offs...IE. from 2005 F150 that I can use on my truck? And will changing tire size affect computer/speedometer/milage. Thanks a lot.

 

You can fit up to 315/75R16 on there, so anything between your size and that will fit. 265/70R16 is a good size IMO.
