What is the biggest tire I can get on a stock suspension?

I think that the question you SHOULD be asking is

"what are the biggest tires i can put on my stock rig and NOT rub BADLY on the trails when I go offroad and try to flex my suspension --which I will need to do in order to make it up the trail"

The answer is 31" or 265x70xR16 - IMO

I'm running 265/75-16 Yokohama's (they run big). True I have 3.5"+ of lift but flex flex great, all the way to the bumpstops. I had very little rubbing before I added wheel spacers. Even with the spacers I only rub some, not bad at all.

A good flexing suspension, lifted or not, should compress to the bumpstops. Since a lift doesn't change the bumpstop position, you will have the rubbing when fully compressed. Compressed is when you will have the most rubbing.
 
Rockdawg has 35s stock. Lol I don't think can even turn.

Oh they turn and don't rub :guitar3:. There was a lot of clearancing (very big Hammer) to make that happen though. lol. If you plan on wheeling, especially in the front, the largest tire you can run is whatever you can run on stock suspension because the IFS runs through the same suspension travel no matter how much lift you have. if you want to run big tires you have to clearance without the spring and strut in the front and the suspension on the bumpstops and with the tire running through the whole turning radius, or bL until your above the tire when fully compressed. I do rub on the frame at full lock but that I can live with. And I have finally installed my kings up front and 8 wraps in the rear. the reason to lift for me has more to do with breakover angle than tire size which is also why I don't run a bL as it doesn't help for me. I'm coming up on a nice balance and look forward to wheeling some more stuff in the 98 as the AC works really well and its hot right now. lol

While the general consensus is 265/75/16 there are some exceptions.

I had major rubbing with 265/75/16 duratracs with new wheels. The aggressive thread coupled with the wheel's backspacing (wide) made for some bad rubbing. Like I would turn heads as I pulled in and out of stalls. A 2.5" lift took care of the problem.

No, the general consensus is 265/70/16 not 75 unless you want major rubbing on the trail with your stock suspension. The rubbing can make you worse off than with the smaller tires because you can't go up the trail due to flex rubbing.

Other than that sorry to jump all over your post fellow San Diegan!

It's all good. I don't take things personally, especially on the internet. Do you wheel anywhere in the SD area or other parts in the county?

To clarify my statement...a lot of people will say 265/75/16. There are 3 mentions in this thread alone. Just trying to point out that 265/75 can rub under certain circumstances, especially, as you've pointed out, on the trails.

So even if you have a 265/75/17 it wouldnt fit? Sorry if it sounds stupid but i dont understand how changing the rim size would effect it as long as the tire is the same size.

The reason i ask is because i have a chance to get a brand new set of 265/75/18's and i was thinking about getting an 18 inch rim for them. I have no idea if it would work or look good, just looking into it since i have the chance.

A 265/75/17 is larger than a 265/70/17. the 75 (32.64") is an inch taller than the 70 (31.60") and the 75/18 (33.64) is an inch taller than the 75 and 2 inches taller than the 70. When going up a rim size you have to go down 5 on the profile (middle number) to have the same size tire. That's why a 265/70/17 is the same size as a 265/75/16.
 
Less backspacing on wheels (less than the stock 4.65") can cause more rubbing on the fenders. Also wider wheels.

I wouldn't think twice about running 265/75-16 on stock wheels with stock suspension.

A 265/70-17 is almost the exact same size as a 265/75-16.

Most of my rubbing came when I added wheel spacers. This made my effective backspacing 3.4"
 
Going from 265/70/16 to 265/75/16.

:driving: When I bought my used 4Runner it needed tires so I looked up OE tire sizes as options. BFG showed a 265/70/16 AT K/O tire as OE equipment on my 96. That is what I ordered and had installed. That was about 98,000 miles ago and they still just passed inspection! I got a great deal on bearly used 265/75/16s and will be installing them when I hit 100,000 miles on this set and retire them. I mainly use them on sand and snow and I don't expose them to high flexing off road. The larger tires should be fine do you agree?
 
The PO put 235/85r16s All Terrains on my stock 4Runner. They are 31.7" tires. They seem a little bouncy to me and are meant for max 7" wide wheels.

265/75r16s are basically the same height, just not as narrow.

Spacers FTW.
 
I have a 98' SR5 2wd and have 15" rims. Is there a big enough difference in the suspension between a 2wd and a 4wd that I could not run a 265/70/15? Can I run anything larger because of the 15" rim?

I was at the tire store today getting a screw pulled out of the wife's tire and I inquired about BFG Duratracs. The guy said he could get them in and slap them on tomorrow but needed to know what size I needed. I told him 265/75/15. He said that there was another number and a letter that followed up after those that he would need as well. He showed me on a few of his tires how it looked. The problem is that I don't have a set to look at.

Or should I go with 31x10.5R15s?

Any help? I need to call in the next couple of hours so they can toss them on the truck and have them in by tomorrow. Any time after that and I just won't have the time to do it with the upcoming deployment.

And if I get them... those running boards are coming off!
