Adjusting wheel offset

Plan on buying a TRD Sport and modifying the wheels/tires. It appears buy and large that the largest size of tire that would fit w/o rubbing or chopping is 265/70/17? Can I play with the wheel offsets for a wider stance (I plan to install bushwackers so I am not as concerned with the wheel sticking out past the stock fenders). Can the tires go wider than 265 w/o issue? The TRD Pro rim is +4mm. Is the body for the TRD Sport the same as the Pro and therefore if i upsize to aftermarket 17x7 and +4mm with tires spec'd above, should be no problem??

 

No...
A 285 would stick out 1.25"; a 17x7 et +4mm wheel would stick out 0.5".
The tire doesn't just pivot in a turn, it travels through an arc. You increase the size of that arc, along with forward and rearward movement in the wheelwell, with more poke. There is no 'magic' wheel size that guarantees fitting 285s; especially without some clearance help from a lift.

FWIW, a 265/70/17 would poke out 1" with a 17x7 et +4mm.

 

255 80 17 is a 33" setup. On an OE wheel, no lift, no rubbing, no cutting has been reported by several.

Good fitment is much from the wheel specs and some from the slightly narrower tire than the in crowd tends to run.

Problem with this seems to be that E ratings are all that's available in this size. Which pavement pounders don't need, although they are very rugged for the true off roader.

 

Currently running 275/70/17 on the TRD Pro 4Runner wheels with no lift and I am not rubbing under normal driving conditions. Haven't taken the truck off-road yet to test.

 

Is the TRD Pro the same truck body and suspension as the TRD Sport? If so, i would think that if I use the same wheel width and rim size/offset as the TRD Pro, it should fit no problem. Thoughts?

 

What is the specs on the TRD Pro 4Runner wheels?

 

Will 265/70/17 with stock suspension fit without rub?

 

17x7 4mm offset

 

The Pro, Sport and Off Road all have the same body/fenders/Flares.

They all have different suspension (different shock & spring combinations).

 

Yes. As long as you are not using Weather tech mud guards. Mine rub slightly at full lock.

I'm running the 2017 Tacoma Pro wheels with no spacers. Have 285/75/16 BFG tires. No rubbing. Lift is a 3" OME.

 

does the different suspension play a major role in wheel/tire fitment? how much?

 

All the different packages sit at about the same Height. Pro sits the tallest. I plan to get 265/75r16 soon which fit on all stock 3rd gen. I suggest you do the same. I am running SCS F5 16x8 with 4.5in backspace which puts the sidewall and tread flush with the fender flare to perfectly fill the wheel well. Check out the tire offset calculator for the different combos that you are considering...

 

Are you sure 275/75/16 will fit stock without rubbing? Consensus from what I have been reading is 265/75/16. What is the max backspace before rubbing the cab mount or inner fender? What is the TRD Sport stock tire specs?

 

That was a typo...
265/75r16 fit fine. The 265/70r17 is the same height and width.

I would avoid too little backspace which will put your tires out past the fender and throw rocks and stuff all over your truck sides.

 

I am going up to 265/75-16 after my 245's wear out and they will fit fine on my SR5

 

I plan to add some bushwacker flares on the outside so am not too concerned about the poke. I am more interested in the backspace before it rubs against cab mounts or inner fender walls

 

Backspace is to clear steering/suspension...
Enough poke, will create a big enough arc in tire movement when turning, to interfere at the cab mount area.

 

okay. Do you know the maximum backspace before rubbing the suspension/steering components? Also how much poke would start to rub the cab mount?

 

If you want bushwacker flares and high offset wheels, you will need a lift kit. Do not get blocks & spacers!
