Hi im sorry to post about wheel and tires but i'm still not sure where i stand with sizes. I just picked up a 2012 F150 ecoboost it has the 17" wheels on i don't want a leveling kit just to replace the wheels and tires. I want to get nito trail grapplers tires but do i get 17x9 wheels with 285x 70x17 tires i'm a bit lost. Sorry to sound stupid is there a caculator i can use thank you for any help john.

 

http://www.miata.net/garage/tirecalc.html. One that gives you a idea on how big of a tire vs stock size.

 

what is the goal?

just looking to get better tread? or are you looking to upsize a bit? those 285's are going to be a bit larger than stock, in the 10% range.

there are quite a few people on here with plus-size wheels that could probably tell you what fits and what doesn't, based on if you have a lift or not.

 

I have 285/65/18 terra grapplers on my 2011 fx4 EB with NO lift and zero rub

 

On stock rims? He wants to get different rims if I read correctly. There is where he might run into issues with a + offset on the rims. Just sayin'. You might want to check with someone like www.tirerack.com I'm sure they could answer better than I.

 

Sorry yeah i would like new rims for my 2012 f150 do i go for 17 x 9 with 285 70 17 tires? Would they be a direct replacement?

 

i randomly picked a 285/70/17 (BFGoodrich) at it suggested a rim width of 7.5-9.5"

so if you are looking at rims, and that size of tire, a rim that is 17x9 should work fine with that tire.

I'm not sure of your exact configuration of truck, so i assumed an XLT crew cab 4wd to compare. The stock size for that truck would be a 265/70/17. so your proposed size would be larger by about an inch in diameter.

if you were looking for a stock size, i'd recommend the 265's. even if your truck came with the 235/75/17's (super cab's), the 265's are going to be very close in size to the orininal. The recommended rim size for a 265/70/17 is 7-9", so those would work very well with your proposed 17x9" rims.

depends a little on your overall goal.

if you want some skins that are roughly the same size as the original, i'd suggest the 265's. the choices are vast for this size, and the prices are more reasonable.

if you want to upsize a bit, the 285's are a good choice for your proposed rim size.

you may want your tire shop's help checking the fitmet of those wheels, though. I'm willing to bed that the stock rims are only 8" wide, so your 17x9's will fill the wheel wells a bit more.

if you are looking for the most possible traction, get some 17x8's and hand the most rugged 235/75/17 you can find on them. but i get the impression this is more about looks than raw function.

hope that makes some sense. if not, just ask ...
good luck!

 

Not hijack the thread, but I've been looking at replacing the tires on my 2wd '10 Supercrew. I currently have P265/60/18 and I want to move up to LT265/65/18. I'm also thinking about doing a 1in. daystar leveling kit, but not sure about that yet. Has anyone done this on a 2wd? I don't want to do anything extreme since I do pull a 28ft travel trailer (main reason for the switch to LT from P rated tires).

 

Thank you for your post sorry i dont come on here much i want to get these procomp wheels
Series 7031 - Flat Black Alloy Wheel

and maybe 285 70 17 nitto trail grapplers.
