265/75/16 Tires Rubbing w/1" Spacer

[WrenchTech]

I am having an interesting experience. I took off the factory alloy wheels and 265/70/16 tires and mounted some Daytonas 16 x 8 wheels w/ 265/75/16 tires that I had available. The first problem was that the steel wheels did not clear the calipers at the front wheels. So I got some 1 inch spacers, not planning to run them permanently, but just to see how the different set up would look and act.Then I encountered a new problem. The 31-1/2" tall tires were now rubbing against the pinch weld at the front of the rocker panel when I turn the wheels about two-thirds of the way to full lock. I thought you could run 33's on these vehicles. Was I mistaken?

In any case, I am thinking of running the five-spoke Toyota alloys that came as an option on the 4runners and Tacomas. I think I have read that those wheels will clear tundra calipers. Can I also expect to run my 265/75/16 tires on those with no rubbing?

This is how I hope to end up in the next few weeks. As soon as I can source some suitable wheels and get them painted.

The tire pictured here is a 275/70/17, which is virtually the same diameter, if not just a bit smaller, as the 265/75/16 that I am running. It is roughly an inch wider in the cross-section though.

my stock wheels ( your lower picture) will clear the TBU. If your thinking of doing the TBU, just be warned that the stock spare will NOT clear the TBU. So some resort to ( if flat on front) put spare on rear and move rear to front. I opted for just getting a stock wheel for my spare. Or carry a spacer and install with spare to clear when needed.

As far as if the tires will clear without rubbing, I think a lot has to do with age of springs and shocks. YOu might be at the time where you need new springs/shocks. I installed 99 tall springs and KYB shocks and had no problem with tires clearing,,,,ko2 265/75/16. Now with 50+k on them ( springs and shocks) they recently started to rub (I hit more gravel than pavement so that might have shortened the spring life)
I am installing the tundra billie LC spring lift in the next few weeks so that will fix that. ( have all the parts, just not the time) will lift about 2.5 inches .

Did you check the backspacing on the new wheels? Backspacing (Plus in this case a 1 inch spacer) will affect where the wheels sit in the wheel well side to side which will affect what the tire can hit as you turn the wheels.

Tire size is only half the equation. The other half is backspacing, wheel width, and spacer size. You've moved the tire too far out and that is why you're rubbing.

Your alignment also comes into play here. You may have to tell the alignment tech to max out your caster to help clear the wheel wells (pushes the entire wheel foward)

Definitely looks to be a backspacing and/or alignment combo. Did you recently swap a bunch of suspension components in the front? The wheels don’t seem to poke out too much, but needing a 1” space is pretty substantial. I run 265/275r16 without concerns before and after lifting.

Both are definitely in play here. Max out the caster on the alignment (set it to the top of the available OEM range). Along with that, the extra offset off that spacer increases the scrub radius in the front, effectively making the front wheels travel a wider arc while turning. It'll help you clear the frame, but make body clearance worse.

With the OEM wheels and no spacer, you'll be fine. Also, your current tire size is considered the largest 'no mod' tire size. Above that there will be pinch weld, front bumper valence or more mods needed.

You can run 33's. Here's my cheap-o recipe:

• 1" body lift
• 99 "highlander" springs
• bash the pinch welds
• stock 5 spoke wheels

I've been on 285/75-16's for at least 7 years now.

I believe my steel wheel has a 4 inch backspacing. If I recall correctly, the 4runner wheels are 4-1/2" or four and three-quarter inch backspaced. If my math is right that means that my steel wheels could be as much as 1-3/4 inches farther outboard than the stock set up. I think I will be happy with the results when I get the factory alloys on there.
