285 70 17. will they fit

[86mk7]

What do I need to fit these on a pretty much stock truck. I'm looking at aftermarket 17s right now. I don't want to trim the front bumper either. Will a small torsion crank clear just fine

 

[86mk7]

Anybody know.

 

[bowtiefreak]

yes they will fit just fine so long as you do not have some crazy offset or back spacing on your wheels

 

[86mk7]

They'll be pretty mellow backspacing. Nothing realy crazy. Just some 17x8 or 17x9 with around 4in backspacing and an all terrain bfg retread style tire.

4 inch is more than stock so you may need to trim the valance and the inner rear part of the fender (I just cut that area out)

 

[86mk7]

Well Damn. I'm not cutting anything since its all new. Guess ill stick to a 265 70 17 then. I thought I read that 285 would fit. I can d a small crank but I can't cut anything.

I have 8" of lift on 35s and still cut. It is inside the wheel well, no one is teh wiser and the average guy can never tell

4" backspace is what is getting you...if you look at rims that are 5"+, I've been told you can clear with just a little crank.

As a caveat, I'm just learning all of this myself and just passing on info...if someone here has actual experience (compared to me), pls chime in.

Check out the OBS "Exterior" forum on this site, i posted a few diagrams within the last few days that explain backspacing and what our rigs need to clear certain sized tires.

For what I've found in a black wheel that we like its always around 4.5 back spacing. I've found a few 5 inch back spacing tho to. The offset is what I don't get.

pretty sweet tool...

 

[86mk7]

The wheels I'm looking at are 17x8 with a +10mm offset with a 4.92 back space.

Before I was lifted I ran t 17x8 with 4.5" bs and had to run 265s so I could clear. I wasnt cranked though

96Chevy (a member on here) runs 285's/xx/16 - i believe he did a 1" crank up front.

I'm not sure if he lifted the rear (i.e. blocks) or if he had to cut the front. But the 285's look sick on his rig.

Send him a PM or maybe someone else with 285's can chime in.

I've got 285 Terra Grapplers on 4.5" BS rims. Check out the pics in my profile. I rub still even with a 2" crank. Keep in mind, I have factory flares that stick out a tiny bit more and still have the factory valance. They look good, but if I had to do it over again, I'd just grab some 265 Terra Grapplers from summitracing for $123/each instead of the $200+ I paid for these 10 plys. I have a big heavy grill guard that sank my truck from when I first cranked it, so I'm probably at around 1.5" now...it did rub slightly less without the guard on it.

Hotrod - your rig looks awesome with those 285's!

Where are you rubbing? Any chance for closeup photos of the rub spots?

Do you think a rim w/5" backspacing would have helped?

 

[h0tr0d]

Thanks. The edges of the tires rub at the bottoms of the wheel openings in the back where it curves towards the center of the vehicle. It could be trimmed easily and not noticeable unless you knew what to look for. The valance also rubs at the back corner when the wheels are half-lock, but that's super easy to trim and looks factory if you cut it down at an angle. 5" backspacing on the rims would help as it would probably stop the rubbing on the inner fender.

Hey hot rod. That's exacly what our truck looks like except we don't have flares. Truck looked great. Only difference is our truck has black bumpers instead of Chrome. And ours is still black and white. Lol

86 - post up some pics!!

 

[86mk7]

I have no clue how to even. Lol.
