33x12.5R18 on TRD Rims question

I have read so much... sick of reading...

I want 33x12.5 on my TRD rims... Will it work and will I have to do the cmc

 

What tire brand and model?

Most (if not all) 12.5" width tires are recommended to be mounted on a minimum 8.5" rim. Our TRD's are 8". If you do a lot of wheelin' & crawlin' airing down those tires could cause you to lose the bead.

I'm looking at 305/65r18 which are 12" wide (also recommended 8.5" rim) and 33.6" diameter.

I currently run 275/70r18 bfg KO2's. 33.2" diameter and 10.8" wide. Zero rubbing, zero fender liner heating, pushing, melting, or cutting. Stock TRD off-road suspension.

Most of the guys who really know what they're talking about said due to the backspace/ offset of the trd wheel, increasing width of tire would produce an issue with the UCA and therefore require spacers. I can nearly fit my hand in between there now. Adding .6" (half of the 1.2" difference in the 275 to 305 jump) I don't think will rub or contact the UCA. But I've only measured with the wheels straight on and not turned. I don't know enough about suspension components to understand if turning the wheel affects that space/geometry at all.
Adding spacers pushes everything out which is where you run into the fender liner, mud flaps, skid plate, and body mount rubbing issues when the wheels are turned.

I can math really well, but again, I'm deferring to the expertise of the guys who really know their stuff on here. And I've only got 15k miles on the 275/70's. Not looking to replace tires yet.

 

Nitto mud grappler 33x12.5r18

 

32.95"x12.6" measured on a 10" wheel, I'd imagine yours would be a little taller and narrower due to your wheel squeeze.

 

So trim plastic but should be OK with cab mount

 

Is there a reason you want to go so wide? I think you might hit your UCA's with stock wheels.

 

No reason haha. being difficult i guess

 

So.... New rims (moto metal -24 offset) with the 33x12.5... Will I be required to do the cmc? Trying to get my ducks in a row before I pull the trigger and buy this stuff.

 

From everything I've read, yes.

Better start saving $$ for some bodywork / painting too. Your doors will become very intimate with every rock on the road with that width of tire and offset.

 

ok when you put it that way Eff that... so a 305/70 R18 mud tire on stock rims. PLASTIC trimming only no cmc? If you guys haven't noticed I am against the CMC...

 

305/70 is almost 2" taller diameter than the 33" tires you were looking at (34.81"). You'd likely need some lift. And still probably require a CMC.

 

SMH..... What mud tires do people run on these TRD Rims

 

this is like pulling teeth

 

I think the majority here are running some variation of: aftermarket 18x9" +30 all the way to -12 offset. (Majority in that range) with 295/70r18. 3" front lift, 1" rear lift. (+30 to +18 offset seems to be the sweet spot). Varying degrees of liner modding and CMC's.

That's my forte.

 

285/65R18 Should fit minimal trimming? I really do not want to do the CMC

 

Yes.
Can verify personally that 275/70r18 will fit w/o trimming.

 

285/65r18 will fit fine

 

Sold I'm going 285/65R18 mud slingers

 

I really am shocked that no one stuffs 33x12.5 on a 3 inch lift.... I am tempted because I have found a good deal on 33x12.5 but lack information (the shocking part because of this site)

 

I think you should, as I've been curious myself.

kyle

 

I'm about to go 6 inch lift with 35's and say eff this question.

 

Hahahah. Always an option

kyle

 

I mean...you can stuff 35" General Grabbers on TRD wheels on stock height with minimal hackery. No CMC needed.

 

How? Everyone here has said no go on 33x12.5 but you said stuff 35's?.... Haha could save me 4k if we hash this out

 

Caused a bicker match with the wife about the lift Rims and tires. Either piss her off and do it or make her happy and just get new rubbers

 

Piss her off and do it!!! You only live once and she'll forget about it in a few months......besides....they always find something to be pissed about anyways dude........... 285/65R18 on 18x9 wheels with 5" back space and 0 offset only requires a mud flap sacrifice...... My next tire will be a 305/65R18 because wider looks better and I will be getting new wheels with a +12 offset for the wider tires..... 2.5 inch lift front

 

Yes 33x12.5 & 35x12.5 will fit on the TRD wheels, i have done both. the 33s were on at stock PRO height. and I went to 35s after I installed my coachbuilder goodies. I already had an aftermarket front bumper so no trimming for me. and I have not had to chop the cab mount.

33s.

35s

New vs old and clearance(I have a 1/4 spacer on the front hubs)

 

and I put the 33x12.5 on my coworkers tundra, stock height not leveling kit and they did fit no issues, didnt even rub the skid plate.

 

No one puts 33x12.5's on with a 3" lift because the tires look unproportional. Too wide and too short, the latter being the main thing IMO. Besides that, if you go to a 3/1 lift why only get a 33? A lot of guys on this site have 295/70's or 35x12.5's on that lift, or even 305/70's in some cases.

And just curious, why are you against the CMC? Just buy the plates from Relentless and find yourself a shop that'll do it for ya, easy as pie.

 

This is all true and I agree, 33s aren't much taller than factory and look 'little' even at stock height of a pro. Thats why i finally went with 35s.
