Have a stock 99 F150 4x4 Off Road Pkg. Has 275/75 R17's. Anyone know the largest size I can go with stock suspension?
Thanks!!

 

285s i think

 

You can fit a 315/70-17 (35x12.50) on your truck if you use the OEM wheels. However, this is an extremely tight fit and you will have some rubbing on the frame at full steering lock. Personally, I wouldn't go that large unless you plan on a lift kit in the near future. If you plan on remaining at stock height, I'd stick with a 33 inch tire (285/70-17 or a 33x12.50-17).

 

I was considering a 305/70/17 tire on stock rims, but figured naaa, not for now anyways. So I went with the 285/70/17 and put the black side out. I wouldn't do it any other way. No changes and no rubbing etc. All I have to do is recalibrate the speedo with this little recalibrator I got, after I figure out how to do it. The truck looks like this now:



You'd need to trim a bit off the valance and crank the torsion bars up plus get an alignment for the 305/ 315's. I have seen a pick up like mine with 315's and a body lift and it looks great, but if no mods are to be done, go 285's or maybe 295's, maybe!!!

 

I've run 33'/12.5's on 16x8 aftermarket rims on my 98 with the same Off Road package as you since I bought the truck new. Just had to turn up the torsion bars this spring to keep it from rubbing the splash guards.

 

anybody have pics of 305s on there 97-03? I am getting that size tire at the end of the week and would just like to see if anyone has any pics. Thanks

 

I wish you could see, but for sale is a 1999 or 2000 with 305/70/17's and what looks like torsion bars cranked only, do it and crank those babies!

 

I recently went for 285 70 17 BF Goodrich All Terrains. Look and drive great
no rub.

 

just so i'm right on this.....a 285/70/17 will fit on my stock 17x7.5 rim and i won't have any rubbing issues? ...I have a 01 XLT 4x4 off road package

 

285's will fit a stock 4x4 (wheels included) just fine.

 

I had a slight rub with my 285/70/17's on my 03' Screw, but I also put them on 17x9 wheels. I just trimmed the inside of the front valance about a half inch, now no problems. I have one, not so good (lighting was bad, camera battery died, still haven't gotten to the store to get a new one lol), picture in my gallery.

 

Ordering them tommorrow I think they will be in the next day . No worries I will have a before and after pic.

 

I put 295/75/16's on 16x10 inch rims and with the torsion bars cranked I still had a good amount of trimming to do.
