A: 10” would be my preference. 9" would work, but 10” will put more tire surface on the pavement or dirt.

A: Hello rwi2112, I would recommend the 12" Fuel wheels. This will eliminate any need for trimming the body panels. Thank you for the question.

A: Sir, This tire requires a 10" wide wheel the 13.5" is referring to the section width side wall to sidewall. hope this helps thanks for the question.

A: Hello Roaster, Super Swamper Tires 33x13.50R17LT, IROK Radial should fir your '99 F150 with trimming in the wheel well.

A: Thanks for the inquiry Roaster, the Super Swamper Tires 35x14.50R17LT, IROK Radial part # SSTROK-14 will require a 6-8 inch lift for proper clearance to clear a tire that size.
