I am new to the thread and am glad to be a part of it. I was wandering if I could fit a 285/75r16 tire on stock 1998 f150. Also if the will fit on the stock rims?

 

Yes that's a good size for a stock rim as far as tire wear and they fit on a stock truck with stock wheels

 

They fit, but you will likely have rub at tight turns on your lower valence. Either crank your t-bars, or trim the valence slightly, and problem solved.

Don't crank your tbars. That'll throw it out of alignment. There is kno reason to pay for an alignment when you don't need the tbar crank in the first place. You won't have to trim either. It's only one size up from the optional stock size. You can run 305/70r16 on stock wheels with no tbar crank and no trimming also. Also a 295/75r16 with no crank or trimming. If your using your stock wheel no problem man.

 

I ran a 285 75 16 on my 2wd when it was stock for 3yrs and had no problems. also i ran a 305 70 16 and only rubbed at full lock on the sway bar, so if yours is 4x4 then you will definetly have no problems with rubbing.

 

Thanks for the help. After see what all you guys said has pretty much made up my mind about the tires. Also I am not to worry about having to realign the truck after cracking the T-bars. I go to an Automotive school so I can do the alignment in there.

 

If you crank them, i think you should go bigger than 285's. Just my personal preference tho.. I wouldn't crank them until you had to just bc of the added stress

 

I'm running them on my 97, no issue at all.

 

imo cranking the tbars is terrible. i ran cranked tbars for a year before going with the leveling keys and had nothing but problems. i replaced countless tierod ends, idler arms, and wheel bearings in that time, heck it got so bad the the local advanced auto parts stop granting me a lifetime replacement on the parts due to how many times they "failed". if you are going to get new tires go with the 285/75/16, and get a set of leveling keys. they run about hundred dollars and imo will save you a giant headache. since your in school for automotive mechanics, just throw in the leveling keys when you get the tires on and like you said a free alignment. and voila you have an awsome start to a bada** rig.


here is a link to a few choices of leveling keys.....

the rough country leveling kit is an awsome deal you have the option of 1 inch blocks and new shocks as well. good luck to you

 

To the OP, DON'T do this. those things are terrible plus you can do pretty much the same thing for free by cranking the t-bars.

 

X2 do not buy the leveling keys!!

 

if you are 4x4 then 285/75/16 will fit on stock rims with no rubbing. If you are 2wd as my truck is then you could have some rubbing in the front. when turning and maybe the valance

 

I saw t bar crank up there and assumed you were 4wd. is that right? Either way 285/75r16's fit without a leveling kit.

 

yea i agree dont buy aftermarket keys. its a waste of money and both my truck and my dads has cranked tbars almost maxed out and havent had any problems and it hasnt messed up the alignment. So feel free to crank them and my 97 was able to run 33s with out any lift or kits. just cranked t bars a bit.

 

Increasing the torsion bar preload is increasing the torsion bar preload. Period. The problem with the aftermarket adjustment keys is that they allow you to put way, way too much preload on the bars. It's like most things, a little is OK but if you take it too far, it will cause problems.
