New here / offset/spacer/UCA guru needed

More lift only solves rubbing if you never cycle your suspension. Horizontal clearance while turning is typically the problem. Finding a rim with the appropriate offest/backspace is a good start, but that's just one factor.

 

Don't go spending money until you know what the problem is.

Are there corresponding marks on the tire? Would likely be the entire circumference. Are there marks on both UCAs in the same place? Do the tires rub now when you turn lock to lock?

It's possible those marks on the UCA have nothing to with the wheels on the truck now. There is clearly daylight between the tire and the UCA, so I don't see how that would happen. When larger tires rub, it's the frame and/or the fenders when turned full lock. If your tire is rubbing the UCA, it would be right at the ball joint.

 

Makes a lot of sense I just assumed that was the issue because it is so common. I’m not sure what those marks could be from then any ideas ?

 

Any ideas what it could be

 

Do you see any adjacent rub marks on anything else?

 

No, but it’s on both sides... maybe when it’s in 4WD and fully locked when turning?

 

4wd or 2wd shouldn't make a difference. I just don't see how a tire would rub that specific spot under normal suspension travel, big tires or not. It's just a weird spot that it appears to be partially on the underside, which suggests to me the suspension was compressed when it happened.

For the record, the difference in diameter of 265/75-17 and a 285/70-17 is negligible (0.06") and the width is about 0.75".

If you don't see any evidence of rubbing elsewhere (frame, fender forward/behind tire, cab mount), chalk it up to a previous owner and go enjoy your truck. Personally, I wouldn't worry about it unless you're rubbing now.

 

Also, might want to throw a little paint on those spots just to keep the rust at bay.

 

I head and feel some rub right when I first start up and drive but then it seems to go away .. I feel like something Is up ... i only test drove one stock taco before so..

 

Those are tire rub marks. Tires flexes. You see the rub marks on different spots because it happens when it turns, and it happens when you go over bumps and dips. I suggest you get aftermarket UCA's. Spacers will only have your tires rub elsewhere.

 

Any recommendations on a good set for a fair price?

Thank you everyone for the responses !!

 

SPC or JBA would be your best bet. @Wheeler's Off-Road Inc

 

Any theory on how something like that would happen? Getting sweet air? High-speed turn aired down?

 

I only know what it looks like because I've seen it personally on someone running 285's on stock wheels and UCA's. It's when the truck is moving and turns, the tire flexes and hits the UCA's. It doesn't have to be aired down. Just the nature of tires. The road has to be completely level for it not to flex.

 

Hmm. I had 285/75-16s on stock wheels and didn't experience that. I guess that's why I thought it was odd.

 

Incorrect offset on those aftermarket wheels perhaps?

 

Can be dependent on a few things like type of tires, psi, driving style, etc. The OP has minimal rubs from the pics. I've actually seen a post here where someone bought the truck running 285's and the stock uca's were actually cut so that the tires didn't rub.
