I just got through reading some threads asking about what size tires are OK to run on stock wheels and some say to not run 285's and some say its ok.

I am planning on running 285/75R16 BFG Mud-Terrains on stock 4runner wheels (16x7), BFG's site says they recommend 7.5-8 in. wheels...I really don't want to have to drop the cash to buy new wheels as I would have to take a loan out on em, I'm barely scraping the bottom of the barrel to get the lift and tires alone.

Will I be OK? What about tire wear?

Thanks guys!

i did it on my last 4runner, and it worked out fine for me. almost exact same tire, except just the all terrain.

 

I did for about 6 months, and it was fine. 285 BFG MTs.

At first I had some rubbing issues on the upper A-arms which sucked... turns out the guys who aligned it actually screwed it up and it was a good 1/4" off ??! So it was rubbing .

I ended up bying some 1" bolt on wheel spacers from marlin and it added a wide stance nad had plenty of clearance.

 

if you decide to get a loan...

I had the same concern FInk, but I'm running 285's now and nothing has been a problem so far.

I even wheeled it last weekend on 18 psi and no issue of bead popping or anything

 

Ive been running 285`s on stock wheels, for about 8 months now, I air down to 15-10 psi no problems here.

 

Awesome! I was really concerned, I never even though about this as a factor. Which is weird because when I had my old 2nd gen I had to upgrade to a bigger wheel so, I guess it just never crossed my mind!

Thanks fellas!

It's perfectly fine on a 7" wheel, even a 305 would be ok. I have 285's on 16x7 Tacoma wheels on my 4Runner and I have run 285's on 7" wheels on my work trucks for the last 450,000 miles and no problems.

 

You won't have any issues I think of other than overall stability. The wheel spacers (reasonable, an inch or so) would be nice when you get the money together, this just gives you a little more clearance and overall stability.

 

Had no problems here when I ran 285 Dueler AT's.

 

I've got the same setup your looking at and it's worked fine for me for the last 2 years. I get some rubbing on the upper a-arms when the swaybar is disconnected and some slight rubbing on the frame with compression and full lock.

 

Wont the center of the tire wear out quickly when not aired down?

I asked the same question on some other forum not too long ago and the basic response was that the chances of the tire popping off the bead when aired down was less likely but when aired up the center of the tire would wear significantly faster.

 

285/75R16 BFG AT KO's on OEM 16x7 wheels at 40 PSI. No problem, even tire wear, great gas mileage. Had them down to 16 PSI in the Outer Banks, NC. No problem.

Alignment, air pressure, rotation frequency, and driving style will make a much more significant difference in tire wear than having a rim that is .5" narrower than the manufacturers recommendation.

 

i do want to state though that the tire and a-arm clearance is absolute none! It is wayyy too close, I have mine shaved down a bit and still worries the hell out of me. For street driving though you should be ok

 

Why? It is not under constant contact. It is only occasional. If a tire can thrash agains the rocks over and over it should be able to handle an occasional rub against a smooth piece of metal.

 

Ran 285's on stock 16x7's with rubbing on the upper a-arms. Thats all though. Even aired down to 11psi at tellico.. no prob.

 

til it starts rubbing more and that rubber to metal causes the metal to heat up and melt the rubber

oh, but i don't care. just thought i'd add to the fire.

 

I'm saying if your tires rub, get your truck aligned and you'll probably be fine...

There was only like 1/4" gap between the tire and upper a-arm though...which was too close for comfort for me.

 

I run 33/12.5-15s on stock 15x7 alloys. My tires are a bit taller, and about an inch wider, on smaller wheels. I've had no problems at all. Proper inflation is more important, but that's really all you need to worry about.

I've heard arguements that wider tires on smaller wheels is actually safer, as there is more pressure on the bead to hold it in place, even at lower PSI.
