max tire sizes.
Planning on installing the day star lift I'm also wandering what size of tire I can fit with the lift I found the bfgs in a size I think will work but. It sure
After you have installed your Daystar lift you can run up to 30" tires.
16" factory wheels - 235/75R16 = 29.9" - 235/70R16 = 29"
17" factory wheels - 235/70R17 = 30" - 235/65R17 = 29"
18" factory wheels - 235-65R18 = 30" - 235/60R18 = 29.1"
With any of these tire sizes you will need to move the tire out 1/2" to 3/4" farther than stock to clear the lower spring perch on the struts. You can either use spacers or change to wheels with a different offset.
The factory wheels come with 40mm positive offset.
For example, wheels with a 17mm positive offset will move the inside edge of the 235/70R17 tire out 0.51" and wheels with a 10mm offset will move the inside edge of the 235/70R17 tire out 0.78".
