Going Bigger - 5th Gen Tire Fitment Guide

[Sully888]

I’m sitting on just over 2” of front lift and run a -10 offset wheel. I do not rub at all with 285’s. I also have my caster at close to 5 degrees with Ironman UCA’s.

Just a quick question, is there any part of the vehicle close to rubbing even with flex?. So far I have a 3 inch front, 2 inch rear lift with JBA UCAs, Viper cut and running stock wheels...lol

My tires are finally wearing out and it is time to upgrade. I have a set of 17x9 wheels with 4.5 backspacing and -6mm offset (close to yours I assume). Just wondering if I do go to 285s, what I am going to have to cut next?

I just fit Toyo AT3 in their new size 34x10.50.

Pro wheels, with 2.25 lift

Fender liner pushed forward and trimmed, JBA arms, front mud flap removed.

I had my caster maxed at alignment. I have maybe 1/4” clearance from the body mount, and about 1/2” from the JBA arms hitting the tire.

It fit though, no rubbing. I added super bump stops up front as well just in case, but so far haven’t made contact on full lock with the wheel stuffed as much I can screwing around on curbs

The only part that I ever rubbed on was the front fender area before I pushed the liner back. I have 8.5” wide wheels so not sure if you having 9” wide would play a bigger part in rubbing. Every vehicle is different, so hard to say.

So you maxed the caster out, do you know to how much?
I don't think you can really test for rubbing on curbs.... Hit the trails and see how it does. You'll need to be in a situation with the full weight of the rig on one front tire and the wheel turned to full lock either direction to test rubbing front and back of the wheel well. Unless of course you don't intend to run trails. If that's the case then you're in good shape.
I don't think you needed extended bumps personally. With a narrow tire and stock rim the tire should stay in the well during compression. I wouldn't want to give up any more up travel than the lift already took away. That being said a softer stock height bump would be a benefit without restricting travel.

4.5 and 4.4.

Your right though, just trying what I can around u til I do hit some trails which is the plan. I’ve jacked up one side fully until in the bump stops though and so far so good still. Curious how it will do with a front left - rear right type stuff on a trail.

Like the BFGs these are clearly not really a 34. 33.5 unmounted, and with a load more like 30

I bet a 255/80 is actually taller loaded. But, I wanted a little more width

Hey all,

So, I've read through a bunch of this thread and it seems like the general consensus is that it varies 4R to 4R. Hoping someone has a similar setup as me and could provide insight.

Firstly, I do plan to lift the front end a bit more in the near future BUT I am currently sitting at 1.75 inches up front with stock UCAs. Will be putting 2.5in Dobinson coils with UCAs soon. Wheels are Method 316s 17x8.5 with 0 offset on KO2 265s. With sales going on for labor day, I was going to pick up some Cooper AT3 XLT 285s. The 265s have a comfortable amount of room and it seems like all I'll need to do is remove the front mudflaps and do a little bumper trimming and I should be fine.

Anyone have anything similar? Thoughts?

2022 TRDORP
For me, first move was to try and level out the front as I like the stock rear lift. Upgraded wheels to Method 703 17x8.5 offset. Running stock Nitto Ridge Grapplers (265s). Goal was to lift around 1.5 and keep some stock rake. After install, even though I set 6112 for 1.1 lift, I ended up at 1.75. (Not sure why, and I did a boatload of digging). So I just rolled with it.
Did not do UCAs since the general rule of thumb that I have read is that stock UCA can typically handle lift under 2". No rub anywhere. All fit well, but could not get great alignment numbers or much positive caster.
I am kinda OCD when it comes to alignment and tracking straight as I drive alot on the highway. From what I have read and researched, the absolute best way to ensure good alignment and positive caster was to get new higher caster UCAs.
I then installed JBAs and all seems to have settled in; truck is aligned, tracks straight, feels solid at speed.
The byproduct is that I had to remove front mudflaps even though I run stock 265s. This was a disappointment as I was hoping to keep everything stock. Was extremely surprised with this result as I thought higher caster UCA would push the wheel forward even more. But it seems that the new UCA first pushes the wheel back to allow for more caster. Then the caster adjustment during alignment pushes the wheel forward.

I plan on moving to 285s, but I am worried about how much modding I would need to do. I definitely do not want to BMC- there are just zero trustworthy people to do that kind of work in south FL.
To your point OP, each truck is VERY different.

Hope this helps

Reading through this thread, I think I found my answer, but just wanna verify before dropping cash. Wife has picked a Fuel wheel, 17x9, choice of 4.5” bs (-12 offset) or 5” bs (+1 offset).

It seems the 5”bs +1 offset would’ve best considering rubbing. Going to run 2” front 1” rear lift on 285/70r17 Ridge Grapplers.

Just looking to verify my choice.

I run some Fuel wheels with that offset (5" +1). In my opinion it'll make fitment easier. The lift height is really irrelevant honestly. Are you adding UCA's? Body mount cop may or may not be nesecary

Glad I found this, was concerned about 275/70r17's on a stock rig but based on this, looks like there should be no problem.

Now to decide between Falken AT3W, Toyo AT3 and General Grabber ATx. BFG ATKO2's are off the table because I do not like them in the snow we get here...

Really, I'd run Interco TRXus MT if they came in a more appropriate size than 33x12.50. Ran them in a 285/75R16 on my '05 Frontier with just a 2" lift and they were great in snow and off road.

Yes, I have some SPC arms waiting for the truck and the rest of the lift. Thanks for your feedback, greatly appreciated.

 

[taildragger]

I run 285's with -12 offset wheels on a 2" front lift and only rub when reversing at full lock and even then it's only if I hit a small bump or something. Fender liner pushed in with a slight (1/4") bumper trim and front mud flaps removed as well. No rubbing off-road on mild trails

 

[Southpaw07]

My old truck as a reference point. 2017 ORP, Bilstein 5160 (lift: 2.5" front and 1" rear), 17x9 ET 0 wheels, 285/70-17 BFG K02. Minor fender trimming and fender liner mod. Front mudflaps removed.

Tons of great info in this thread, thanks everyone

Thank you!

This is a helpful resource!

I read somewhere that even 17x7 +4 wheels on a 265/70R17 tire would rub on an SR5 premium body, anyone know if this is true? Thats essentially factory TRD Pro wheels and tires and I'd think they wouldn't sell those in a blackout package if they rubbed?

I want to put 17x8.5s on 265/70R17s preferrably with a -10 offset but the wheels I like come in 0 as well. Suspension/lift is stock and wouldn't be changed until I can find one that feels as close to OE smoothness as possible with the car leveled and raised overall only 1 or so inch.

Thanks in advance for any insight! Just really looking to see if anyone put 17x8.5 -10s on a stock size tire in a stock SR5 and had any rubbing issues.

So TRD Pro's have the bumper trimmed at port as part of the overall package put on them. I do think mine would have maybe rubbed without the trim if I turn my wheels full lock; especially now that I have a true 32" tire on (the TerraGrapplers are definitely a bit smaller than some 32" tires out there).

As for your 17x8.5 -10 question, I ran that exact setup with LT265/70R17 Wildpeak AT3W on my 2016 4Runner (which from what I remember was also a true 32" tire). It actually rubbed like crazy stock and required me to remove my front mud flaps along with trimming a bunch of the bumper cover back. I assume you may be looking at SCS wheels based on your request (that's what I had).

Even if you change your suspension, you'll likely rub with that wheel size. That being said, trimming your bumper cover is super easy and not really detectable unless you know it was done, and heat-gunning or removing the front mud flaps is also a piece of cake. Don't overthink it .

if i go with the 17x7 trd pro wheels and 265,70/17 MT baja boss's they'll rub?

They will not rub if you trim the front lower fenders a little. The Pro comes with the lower fenders trimmed at the port and are 1” higher up front over all the other 4Runners. The UCA’s are all the same including the Pro and if you have the proper alignment with positive caster you will not have any body mount or mud flap rubbing. The 17 x 7 +4 offset Pro wheel work well with an aftermarket 265. I’m guessing you have a SR5 or ORP.
Adding a 1” spacer to level the truck would help with nose dive and a level look.

 

[gilli8]

i will soon have an ORP, arrived in port 5/5

thanks for the response, there are so many rim choices that it is a little overwhelming at first, but this forum is a big help , i appreciate everyone who answers all our questions. thanks for sharing your knowledge
