Wheel and Tire "Will this fit/rub" stock, leveled, and lifted info inside (complete with poll)

First thread where I read every post from the first to the last with this many pages. I literally put on some new after market rims that are 17x9 with a -12mm offset this past weekend. I put the stock tires on the new rims since I still have about 30K left on them. I thought about up sizing just one tire size but now fear there could be rubbing simply based on the offset after reading through all the posts on here. Anyone have a similar set up and did they have any issues?

Currently running as stated:

17x9 Rims with -12mm offset
265/65/R17's

Looking to upsize just the tires as I have no lift and don't plan on getting one anytime soon and thought before reading all this that 265/75/R17's would work. If you have a similar set up or advice, feel free to share!

 

Glad you read it all the way through!

I'm not too sure with that fitment. I know that size on stock wheels will work, but due to the width and the offset there's a chance. if you do rub, it'll be a very small amount and most likely only on the plastic which is very easy to trim.

Turn your wheels lock to lock and see if/where the tire comes within .5" of the plastic and that'll help you determine if it'll rub.

 

That was going to be my next question! If I turned the wheels to the max and measured, how much space at a minimum should I be looking for. An extra inch in tire height puts it .5 inches closer so how much should I have for a buffer. Not an offroader to be honest, but dont want to run over a raod reflector and have an issue either...lol!

 

Haha I gotcha.

The best way to do it would be with your suspension compressed. At ride height you can only tell so much, and people get away with 285/70R17 without rubbing with lift and these wheels at ride height. The issue really presents itself once the suspension compresses, even on road like turning into a driveway with some speed you have the wheel turned, suspension compressed, and boom: rubbing.

I've picked the wheel/tire combo I want and then trim accordingly to fit, but I'm not fearful of cutting away some plastic and metal.

If you absolutely do not want to trim but you really want to go up a size the best way to tell would be to:
Jack up the truck and put the truck on jack stands.
Get a floor jack under the tire and compress the suspension, then carefully turn the wheel left and right and see where the tire comes close.
If you go up 1" in tire size you'd need at minimum .5" of clearance, but want some buffer there, so shoot for .75" of room.

If they're not going to clear, don't fear trimming the plastic. Go slowly and you can do it clean to where the untrained eye won't be able to tell.

 

Thanks!

 

I'm in the process of getting a 2019 Tacoma TRD Sport 2WD and I was wondering if all of this information pertain to 4WD only or is this info applicable to 2WD also?

 

In my case I drive a 2wd. It should apply to both.

 

^^
You’re both good.
3rd gen Tacoma’s 2wd and 4x4 are built off the same platform.
1st gen and 2nd gen tacos had a 5 lug 2wd version where this info would not apply.

 

Admin can we please make this a sticky!! It’s not only informative but hilarious

 

@eccracer104 Thank you for posting all of this and continuing to update it for individual questions. I'm mostly concerned about not wanting to do a CMC on my leased truck. I know it's not a big deal, but the dealer might not agree with that sentiment in 2021. One thing that I'm still utterly confused about is UCA's and caster, and how that relates to the cab mount. Is it more beneficial to opt for an aftermarket UCA to keep the tire off the cab mount, or is the factory UCA better for that? I've read both. Up until recently I thought aftermarket UCA's were for increased suspension travel, so here I am. In my case I've got 16x8, 0 offset wheels and would prefer to run 285/75/16 in Ko2 or maybe ST MAXX flavor. Stupid cab mount!
Thanks!

 

You might be good with that set up with no CMC.. I had the same size (approx) 285/65/18 with 18x9 0 offset on my second gen (smaller wheel well too) 2” lift with no CMC no UCA

Some UCAs (SPC light racing is one) allow the wheel to be mover forward in the wheel well further from the cab mount to reduce rub.

Hope that helped

 

@4biker What @Hookedup said would be my recommendation as well since the SPC arms have very easy caster adjustment.

Adding caster pushes the wheel further forward within the wheel well. Moving the wheel forward (towards the front bumper) creates more room between the tire and the cab mount creating less of a chance of you rubbing the cab mount.
Don't ignore the fact that your tire may hit the lower part of the fender requiring trimming there as well.

@AY_ARONTRD didn't have rubbing with his stock UCAs but after adding Icon UCAs had more rubbing.
The stock UCAs had too much caster, and the Icons are in a good spot with a little over 2 degrees (good spot in terms of driving and reducing wear on the bushings) but less caster means the wheel came back towards the cab mount causing rubbing on the fender.

 

I feel stupid even asking lol, but you’re a great resource. Might as well take advantage of your knowledge and make sure:

- Looking at getting new wheels (17x8.5, 0mm offset)

- With slightly more aggressive tires (Cooper AT3 4S) but stock size (265/65/17)

- Completely stock suspension (2017 Sport)

Think I’d rub at all with the wider wheel, pushed farther out? What if I went up to 265/70/17?

I know I could go up a size with the stock wheels. Was curious how the offset and inch wider wheels influence that.

 

Pull the front mud flaps and you should clear with the 265/70R17 tires.
If not, get an alignment and ask them to max the caster out. This will move the wheel forward and give you more room.

Unfortunately with aftermarket parts it's never an exact science, it's a bit trial and error, but you should be safe with that tire size even with the wider and more offset wheel. Being that the tires you want don't have a aggressive sidewall that will aide in minimizing the risk of rubbing the fender while turning.

 

I am going to be doing a Low Range 3/2” lift and getting 33” tires. Most likely Falken Wildpeak AT3 285/75/16. Will tires rub on stock rims ? If yes , Would new UCA’s make it work ? Also eventually going to get new rims. What size 16 inch rim would you recommend? PS Truck is 2019 TRD Off-Road 4x4. Thanks

 

You’ll need either new wheels or wheel spacers. That size tire will mount the stock wheels, but the tire will hit the UCA and you won’t be able to mount it.
Even with aftermarket UCAs you’ll need new wheels or spacers.

 

What would be a relatively safe size 16 or 17 rim ?

 

255/85R16 or 255/80R17 for a 33”
Or 265/75R16 or 265/70R17 for a 32”

 

I meant what offset and rim size would give me best clearance for 33 inch tires. Thanks.

 

You'd have the best luck with either a 16" or 17" diameter with an 8" width, 0mm offset for 4.5" backspacing.
