Deciding on tire size with 3" lift and 4runner stock wheels

So I've been reading all through this forum on different tire scenarios with different lifts, etc. and need help deciding on what to get. I think I've settled on a 3" Pro Comp lift but am torn between getting 285 or 275 70r17. I've seen people saying both ways for both tire sizes that they either work or don't work. My big hangup though is that I have these 4runner wheels pictured (not my wheels) and I don't know how much backspacing they have compared to Tacoma wheels? I feel like they have a little more but I'm not sure?



I want to avoid the cost of getting new wheels since I already bought these and had them powder coated. I also want to still fit a spare tire in the stock position and have heard both ways on if a 285 will fit there or not? Lastly, I want to get away without trimming anything or very little if possible. While searching I've seen mention of a Cab Mount Chop. I haven't looked into that in detail but sounds like it would be best avoided too.

As far as my truck goes it's a 2015 4x4 with 6 speed and 4.0. I don't do any serious wheeling aside from some moderate trails every now and again to access more remote camping and hiking. I would like to do more of that with a lifted, more capable vehicle. I'm not positive but I think my tire size right now is 265/60r17 (I can check tomorrow) Wrangler Duratracs. I like them and would get the same tire in the new size.

Any help would be greatly appreciatedn, thanks!

 

After reading up some more I'm pretty settled on the 275/70 and if I need to I can get the 1.25" wheel spacers. I don't know why but I was thinking they were more expensive than they are. I had ruled them out initially because I was worried about handling at highway speeds too. I do a fair amount of driving at 80+ mph, will I need to worry about that with wheel spacers?

 

I believe you can get away with 285's with 4runner/FJ (most likely 4.75" back spacing) wheels but with a 3" lift, you'd need aftermarket UCA's.

 

Less lift, better components are your first things to consider.

Call Marie @HeadStrong Off-Road for suspension suggestions.

My thought would be to go with a tire size that works with the wheel, no spacers, minimal trimming. So to achieve a side view 'look' of fuller wheel wells that could be a 255 in a taller profile.

You can use the tire calculator to play around with combos that give similar diameters. Remember, too tall impacts performance in several ways, and it doesn't sound like regearing is your goal.

 

Spacers will net you just fine. City or offroad. They can handle just about anything for your needs. Make sure you either go Spidertrax or Bora only and not the gloried washer style spacers which reduce the amount of thread engagement for your lug nuts.

 

285/70R17 will rub when flexed off road. I also had VSC issues going with 285's in the past. Zero issues with a 2" lift and 265/75R16's or 275/70R17's. Expect a hit with your mpg with bigger, heavier AT tires though.

 

Thanks for the input fellahs. I think I like the look of the 275 plus it probably wouldn't be a good call to try a 285 on a 7" wheel anyways. My biggest concern was rubbing the UCA but I"m hoping that wouldn't be an issue with the 275. When doing all this should I factor in buying some 1.25 Spidertraxx or do a wait and see approach before putting them on? I might end up liking the more stance anyhow with them? I have searched a whole pile of pictures but it seems that everybody and their brother gets new wheels when they lift and nobody sticks with stock wheels or even less FJ or 4runner wheels. I just don't like the vast majority of aftermarket wheels where all of them have fake bolts or nuts on them or different black and aluminum sections. Nevermind goofy hubcaps too. I'm striving for the minimalist murdered out look.

 

We have 275/70R17 on an oem 4Runner wheels but it's on a stock 4Runner and not a Tacoma. No issues with rub anywhere.

 

Thabks for the follow up.

I didn't realize that Duratracs aren't made in 275/70/17 so I was up late last night looking at Cooper Discoverer ST and ST Maxx, seeig how they looked on Tacomas with different wheel options and in different sizes. I was even playing around with looking at 255/80r17 tires and such but I don't know if I would care as much for those tall skinny tires.
