Wheel & Tire spec question: 17x8.5 et +35 with 35x12.5" tires and stock UCA?

Is anyone running 17x8.5 wheels with +35 offset and 35x12.5 tires on stock UCAs?

Method and a few other brands sell this wheel spec, but despite my searching I cant find anyone who is running a 35x12.5 tire and stock UCAs. I don't mind trimming the skid a little if needed. Looking for minimal tire outside the wheel well.

If yes, what tire? Pics of the UCA clearance would be super rad.

Thanks in advance

 

Anyone have feedback for this setup? Thanks

 

I don't have experience with that personally, but some others might. Some more info from you might help too (year and suspension setup to start). This topic is quite the bludgeoned horse and there is gobs of great info on this forum. Here are a few rabbit holes to dive into:

Thank you. I have used the search and spent hours scrolling already, and will keep digging.

I probably missed a post in there somewhere, but have yet to find confirmation on the exact configuration I described above.

 

You’ll clear with +35. If you’re running your stock rims, then you’ll for sure need to add spacers.

 

This is 37x12.50 +12 on SPC UCA, but you’ll get the idea.

 

It's a lot for sure. I'm pretty sure that will clear your stock UCA (they're relatively small vs aftermarket). It'll be probably a hair tighter than a stock setup, but you should be fine. What's your intended use for the truck & upgraded wheels/tires/suspension? Parking in the grass every once in a while and looks? Or are you hammering trails w/ boulders logs etc? As the suspension cycles, distances and dimensions change, so you could run into some trouble if you're really getting after it.

 

So I don't have any experience with this exact setup. But like you I did extensive digging before choosing my current wheel tire setup.
I'm running a 17x8.5 with a +25. Tire is a 34x12. In order to get these to fit and not rub I did a 2.25 lift in the front and the normal plastic work up front. (Eventually I shimmed the bumper too.) Once you get to the 2.5 lift or more is when ppl start recommending UCAs for clearance and proper alignment.
Do your research, you may come up with different recommendations. But my research told me that I 'could' run 35s but would be seriously pushing the envelope and the max specs on the UCAs, and still may be out of alignment, and very likely still be getting a rub at max turn in reverse. Either it was gonna get a lot more expensive, or I was gonna be asking for a crappy ride with no room for adjustment.

 

Thanks for the responses everyone! Intended use will be mostly camping around CO, but want to be able to cycle suspension without issue and get the alignment correct. Planning on 6112 up front at 1.9" setting, and don't mind trimming/spacing the front bumper and/or doing BMC. Was hoping I could get a proper alignment with this wheel/tire/coilover combination AND the stock UCA.

Need to be careful talking offset and different rim widths... I like the 17" wheel options from Method and was looking at 8.5" wide wheel with +35mm offset.

I have seen confirmation that 18x9 +25 will work, and based on this online calculator it seems like 17x8.5 with +35 will be 0.14" more inward (closer to UCA).

 

I ran a 35x12.5 on stock 18" TRD wheels with no spacers (2nd gen 2012) and with stock UCA. Had a 2" lift and only had to trim the skip plate to eliminate rubbing.

 

+35 is the key, should clear UCA. That would be about the same offset as the stock wheels with a 1.25 spacer which does clear UCA with 1250 wide tires.

It is a great offset for a Tundra, wish there were more wheels available in that offset.

 

Thanks for the replies! Would be super cool to see a pic of the clearance to see how much room there is if anybody has one handy.

 

this should be helpful, and there is another thread link in this thread

I will be running a very similar setup soon. I already have the +35 offset wheels and i just ordered the 37x12.50 tires to go on them.

I am running an aftermarket UCA but it has very similar clearance as the stock one.

Right now, with stock wheels and tires, I can tell that if the tire was taller, my UCA would be buried in the tire sidewall.


That is with a stock tire on a stock +60 wheel. The new wheels are +35 but the new tires are also wider than stock. According to this online calculator, the difference is pretty close to a wash. I might gain about 1/8 of an inch of clearance if anything.



My current plan is to wait till the new tires come in. Try to install them, and if i need to, order an appropriately sized spacer from BORA.

I already ordered some extended wheel studs from ebay, https://www.ebay.com/itm/164876042315 which i am going to use whether i need a spacer or not, simply to avoid having to use extended collar lug nuts.

Anyway, I'll know more by Monday or so. I'll report back with what happens.

 

ICON REBOUND 17X8.5 +25mm offset, 315/70r17 with stock UCA, no rubbing.
I can get a picture of the UCA-Tire side wall gap later


And the poke isn't too bad. IMO +25mm is where it's at in terms of larger tire fitment.

 

Thanks a ton guys. I wish there were more wheel options in 17x8.5 width and +25 offset. I know +35 will be close to the UCA with a 35x12.5, but curious to see exactly how close.

 

OK, just ran out to the truck and got these pics for you. I don't think 35mm would be a problem but it would be too close for my comfort, given that I got the narrowest 315 width tires (section width), YMMV with 35s, but 25mm would definitely provide a safe amount of gap with any 35s.

And I feel you, I was looking at 25mm wheels, I think the only good ones are ICONs and method 316 (happen to on sale now)

 

Really appreciate the pics! I am tempted to try the +35s. Just to be sure, you are running the ICONs 17x8.5 +25, right? What brand/model tire?

 

Correct on the wheels, for the tires

BFG KO2 315/70R17 Load range E (NOTE: Load range E has a narrower section width and tread width than load range C for the KO2s in the size of 315/70r17)

 

You don't need any lift for 35s. If someone wants to "level", then raise the front 1.5-2.25 and you'll be fine. Then when aligning, set the rear LCA pivots all the way out, and adjust the front ones to get camber right. You should have good caster and no BMC needed, but you'll probably want to space the bumper with some 5/8" nuts and move the liner forward.

OP... you'll have no problems with clearance. Though I have rims that are 10mm more outboard, they are also 9" vs 8.5" and the tires are wider. I got about 35mm space, and I thing 10mm would be adequate... maybe even 5mm.

 

I agree with almost everything you said. Except for the "set the rear LCA pivots all the way out" part.

It isn't the greatest idea to be at the maximum adjustment angle for two reasons. The first being, once you are at the maximum, you can't adjust any more if you need it. The second being, twisting the LCA that much puts extra strain on the bushings making them wear out faster, meaning you run into issue number one faster as well.

But if you are willing to accept that, then by all means, do it that way. It will be easier to set up now in exchange for more maintenance later.

 

Good info on the E vs C BFGs. I had heard that the K02s tend to run a little smaller than some other brands, but didn't know about the different tread width.

Thanks for the alignment recommendations. Currently planning on doing 6112s up front with the 1.9" setting. Your wheel specs are 9" width with +25 offset, correct? This is giving you about 35mm clearance (1.4")?

 

35x12.5 are usually ~34.6" and are measured on 10" rims. 1" of rim width is ~.4" of tire width. So 35x12.5s on 8.5" rims will be ~34.6"x11.9".

 

I also run 6112/5160 with 1.9' setting up front, so it will be a good baseline for you.

 

Yep. And my tires are ~.8" wider than a 12.5 on a 8.5" rim.

 

Thank you. Sounds like my proposed setup will work. No concerns with the stock sway bar, right? ...in case I decide to keep it on

What is your tire size on the 9" rim with +25mm?

 

There'd never be a need to move the rear ones out further. But I did wonder about the bushings... when I first looked at how the alignment adjustments are designed I couldn't believe it... seems like such a kludge. Look at how the stock configuration is, though. The front or rear is set to the top, and other to the bottom... so the stock configuration already has max misalignment of the pivots, just in a different direction. I think they're probably ok like that...

 

In the sig... 325/65r18... should be 34.6 x 12.7 on 9" rims.

 

Ya, I agree. You can. Ive seen the video too.with literally the same rims I'm running. Just stating my own experience with a similar wheel offset and a slightly smaller tire. My clearance on my UCA and skid plate were never even an issue at +25. Had I put a 35" tire on I'd be real close to needing a BMC, my caster would have been even closer to max and my front end bumper work would have been that much tighter. However, oddly enough, I think I'd still have room for the tire to clear the skid plate and UCA.
