What are the biggest tires which can be put on the factory wheels for a 98 F150 V6 5 speed? We want to do a 3" body lift and want the truck to look bad ***. This is a project I am helping my son with later this summer. Please advise. Thanks.

 

all 4x4 f-150's have the same tire size, engine size has nothing to do with it. but most people start with 35'' tires when they have a 3" lift and go up from there. personally, if i got a lift i wouldnt go anything smalller than 35'', b/c a f-150 w/ no lift already has a bunch of space for 33''s and such, so go w/ 35 or 37 or somethin.

 

I have had a big probelm deciding how to go about lifting my 03 4.2. i have read alot about the gearin being really high, people seem to talk about regearing even for 33's. so i really want to hear from someone who knows if you can even put only 33's without regearing and come out not hurting the truck too bad? but as far as the on stock rims as you are talkin about, the biggest tire i could find that fit a 7.5 inch wide rim was a 305/70/17...witch is a 33. somethin ' tire. I have a friend with the 5.4 and he eaisly cleared 305/70/17's by cranking the torsion bars. so if you find out anything more id love to know!

 

I have a 07 f150 4.2 v6 5-speed with 3.31 gears and I have 33 mickey thompson baja claws on my truck only lift I have right now is a 2.5 AS leveling kit......Ive had no problems with having them on my truck with the gears I have now, am I going to regear...yea probably to 4.10-11s since I do alot of highway driving.....but I havent had a problem so far......I still get about 17mpg highway with em. Later on after I lift it im going to 35s so yea! if you have any questions feel free to ask

 

Thanks, that helps alot, i was startin to stray away from goin bigger. how high does your truck sit with 33's and a leveling kit? i looked for pictures of your truck but i couldnt find em.
