1st Gen Tundra Tire Setup

Plug in the numbers: Look at the original tire size you want to compare. Open a new tab or browser window. Input the new tire size. Compare the height/width/diameter of both.

Anything much wider and/or much taller, you're liable to rub.

 

It’s 2.4 inches bigger in diameter, 1.4 inches wider, and bigger in circum, but has less revs/mile, y’all tell me what y’all think, stock is 245:70/16

 

What's the overall diameter? @bmf4069 is access cab, and running 255/85R16 at 32.8" and I haven't heard him complain about excess rubbing.

YSK it's unwise to compare your access cab to double cab, or take advice from double cabs. The suspension geometry of RC/AC trucks is about the same, DC trucks are more like Sequoia. It makes bmf is a great comparison for you, same cab, same 16" tire size, same general details. You may already know this, if so, ignore me.

 

It is 31.9 in diameter, and mine is an access cab too

 

Yep, I got that from your truck info under your username. That's why I thought it a good comparison.

Which kit did you choose to level the front, and are you running anything for lift out rear (blocks or otherwise)?

The one thing that won't be apples-to-apples with bmf's setup is potentially the backspace on the newer T4R wheels you got. But generally speaking, if you run the numbers on the tire bmf is running (I just posted the numbers up there ^^) and yours comes back smaller in all dimensions, the only thing that may bite you in the ass is him having potentially ~1.5" more lift in front and rear over your setup.

I'm not going to put my rep on the line by saying "won't rub!" I'm not familiar enough with OEM T4R wheels in 16" size (I didn't even know you could get those in 16s), and w/o having backspace info on the wheels to compare that makes it tough. I do find it helpful knowing someone with the same cab type, wheel diameter, etc. as you has something you can at least vaguely compare to, though.

 

I have a supreme suspensions 2 inch level for the front, I would’ve bought some blocks but at the time didn’t think about it, and the only problem is I’m trying to run 20x7 4 runner reps but since the rim is so skinny I’m limited to what tire sizes I can put on, the most popular size aftermarket wise for these rims is the 275/55/r20, but that’s probably the biggest I want to go without adding more lift to it

 

Wait I just now realized, how did U know I was running T4r Rims/reps?

 

Shifty works in mysterious ways

 

Very

 

I'm the wrong guy to ask about updating from 16s to 20s. I think 20" wheels on these trucks looks like ass, but trying to figure out all the variables in that ... I don't want to be responsible for wasting your money. I'd recommend hitting the wheel & tire subforum on here.

​

 

Well first off that would make sense, only problem is I’m bought the rims just trynna find a tire size that should be good, some people go with that size of tires and a level and say it rubs only backwards at full lock, I mean I’m not running that big of tires cause it’s only a 2 inch level, just making sure they will fit, and thx for your help and time

 

I'd definitely hit the wheel/tire forum and see what they can tell you. Someone'll probably link you up with this thread, but hopefully have good advice for you also. I just don't want to tell you something you take to heart and find yourself buying tires that you end up needing to replace.

 

Yeah I mean allot of people with A level and that same tire size say it don’t rub, and if it does it should be minor, but one last question, is there a difference with tire cleanerance/fitment between a sr5 and a limited model?

 

Those are just trim packages, not technically different models. Those packages came with different OEM wheel options, but suspension-wise, I don't think you're going to find a difference. The big differences in clearance seem to be more tied to cab type than anything.

 

Alr thank you

 

No. You're going up in size about 1 1/4". You're fine.

 

Alr thank you

 

I also have 1.5" spacers. It has a slight rub turning left and going through a bump, but only cause my caster isn't set right. I'm betting those 275s would rub w/o spacers.

 

What would they rub on, the upper control arm, or the frame or what?

 

Mine rubs on the inner fender on the back. With wider tires w/o spacers I could see it rubbing the frame. Pinch weld might be ok.

 

What about a 285/50/r20, would that rub any worse than the 275/55/r20? I’m not worried about it rubbing if it’s on full lock and I can trim whatever it is rubbing, I just don’t want it rubbing on a control arm or the frame

 

A 285/50r20 is 11.5" wide and recommends an 8-10" wide wheel. The 20x7's are too narrow.

 

Huh that’s weird but thank you for letting me know, a 4 runner forum listed that size as a tire you could put on it, but off the top of your head is there any 265’s for the 20’s?

 

New to the forum, also interested in the answers to this for my 20" Enkei Wheels on my XSP. Need new tires. Current set is 295/45/r20 and as others have mentioned they don't look good. Thanks in advance, absolutely loving the wealth of knowledge available on here. Long time reader, first time poster.

 

Looking for some advice/reassurance. Found a deal on some 285/70/17 with the wheels being 0 offset with 4.75 back spacing. Everything I've read says these shouldn't be a problem or minor rub. My truck is a double cab 4wd that has a spacer lift from the previous owner. It's also got 285/75/16 with a +5 offset. After having the frame corrected and new suspension put on (uca,lca, ubj,lbj, outer tire rods, and shocks) I noticed the smallest amount of frame rub with a really old set of nittos that are worn and cracked. I'm either going with the set/sizing mentioned above or buy new 17x9 -6 with 4.76 offset and try to go with 265x70x17. Should I go with the used set that are virtually new or order the others?

 

That’s a lot of info you just tossed out. Hopefully I’m not misunderstanding you.

You mention +5 offset. Offset numbers mean nothing unless you provide wheel width. You need both numbers to properly calculate backspace. Backspace and alignment are the main influencers of rub.

if you are running 285/75/16 now, 285/70r17 is same width, but (in theory) a hair smaller, and should fit similarly BUT, the warning I’d issue here…. without knowing the exact brand, model, and load rating of the tire, nobody can possibly answer your question accurately. Every tire manufacturer has different actual tire diameters, depending on the type of tire. For example, BFG KO2 at 285/70r17 will run 0.1-0.2” large. Mickey Thompson Baja Legend EXP at 275/70r17 will run 0.3” large, and that 1/3” makes a huge difference. All manufacturers post up their specs by tire, typically, to help you figure it out.

That said …. The 285/70r17 should be 0.1” smaller than your current 285/75r16, but … look at the difference I just posted. If the brand/model/load you choose is 0.3” large on that 285/70r17, you’re gonna be totally screwed.

Based on current tire, the 265/70r17 will fit, no rub, all day long. It’s only an inch or so over stock diameter and less than half an inch wider. It’ll be smaller, than the other tires you’re referencing, 3/4” less width, and almost 1.5” less tall (so 3/4” off top and bottom). That will maybe be something you’d notice, visually.

 

PS - if you haven’t already read, you may want to see the “Suspension, wheels & tires” section of this thread: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

It’ll offer up some additional guidance and warnings that may help.

 

1. Sorry about that, been going back and forth on multiple forums/Facebook groups trying to make sure I had all the info I needed. I've got conflicting answers through everything between lift spacers, wheel spacers, offsets, and everything else. I'm pretty sure what I've got now are xd addicts 16x8 or 8.5. I don't have a good place to pop off a wheel at the moment. I had the backspace chart from here on a tab, but refreshed and lost it. The set on market place are fifteen52 turbomacs with wildpeak at4s.
   
   
   I've gone over all that information probably more than anything else and it has been a life saver so far. This truck has been a nightmare since I found out everything that's been wrong and hacked back together, but I was too deep in it to dump it and try again. Eventually I'm going to take the truck to lextechs near Atlanta to get a mechanical inspection done, but I'm in desperate need of tires. Thought about just buying tires for the current wheels and stepping down to 265s but with everything else that was bent on the drivers side and the way the truck still shakes, I'm just assuming the wheel is bent also.
   
   Also, sorry about the information dump. I'm trying not to dig myself into a deeper whole or make another mistake with this thing
   

 

Will try to help as best I can. As long as the 285/75r16 is an all-terrain, and the 285/70r17 is an all-terrain, and they're similar in tread amounts, there's a solid chance you can swap out tires with minimal rubbing. There's also a chance you can align out any rubbing you have with the new 285/70r17. But, if you run the measurements, both those tire sizes are ballpark the same overall diameter/width with the 285/70r17 being a smidge smaller overall diameter. But if your 16" tires are at end of life and worn, but the new 17" tires are nearly full tread, I hate to say it, but you're gonna have issues with the new tires **if** that's the case. I wish I still had the full set of Wildpeak AT3s to give you, I ended up recycling the last two because nobody locally would buy them, and it sounds like we're close enough to one another that a handoff would've been reasonable. I hated the Wildpeak AT3, too goddamn noisy.

Really though, knowing the specs on the wheels would help drastically to make an educated guess on those 285/70r17. If the backspacing is closer to 4.5", I'd be pretty convinced you can pull it off, based on the experience of a couple of DC owners here. I have an AC, so my experience won't help a ton.

It may be out of budget, but I am begrudgingly letting go of my gold/black methods which happen to look f'n awesome on white trucks FWIW: https://www.tundras.com/threads/4-gold-method-mr315-6-lug-17x8-5-0-offset-nw-ga-area.151134/

Rim-wise, in all the shit I've cycled through, I was able to get the Rocktrix (silver wheels in background of that thread) for under $600 shipped (I think $580?), they come in multiple colors: https://rocktrix.com/products/rt111?variant=40482979250199

If you specifically want 285/70r17, they came stock on a lot of Jeeps and Broncos. I couldn't find any vehicles that had the 275/70r17 which I run, and I happen to really like the look of. Good balance of rub mitigation plus bulbous/meaty without the extra.

Lextechs in Johns Creek is who I usually deal with. Pretty solid crew there.

 

PS - I looked up the Turbomac, and it doesn't appear they make it in a 6-lug with 6 x 139.7 (or 6x5.5) lug spacing? They do in the HD version, those are 8.5" with offset 0, so 4.75" backspace. Chances are, since all their wheels are probably made from the same castings, others will be similar, but I couldn't find another offset on any of the half dozen I flipped thru.
