What have you done to your Tacoma today? 1st Gen Edition

Anything less than 3 really should be fine. Depending on a few things.

I had 2.25 when I did mine.

 

Thanks, gentlemen.

 

Isn't backspacing the measurement we're the tire is being brought back into the fender? Not entirely sure on what backspacing means lol. Cause I'm going to get a set of Scs F5. But I want to do the tundra brake mod

 

BS is the measurement from the inner lip of the wheel to the inner mounting surface.

 

This. It's a measurement of the wheel.

 

Roger that thank guys

 

So while we’re on the subject of backspacing and fitting tires I have a question.

My wheels that I bought last year have 4.15” backspacing meaning the back of the wheel sits closer to the fender than I want, I think. To run a wider tire than I have now I would need a 1.25” wheel spacer to change the backspacing to 2.9”?

Or do I have that all wrong. I know there are other points where tires will rub depending on the overall dimensions but a spacer would help for this particular wheel?

 

What size tires?

A lower BS wheel or adding spacers is going to alleviate frame rub, but will increase how much you rub in the inner fender/pinch weld area. It’s a compromise, but you can cut/smash/bend the pinch weld area to fit. You can’t do that to the frame.

FWIW, I am rubbing frame a little with 255/85/16 with 4.0” BS.

 

Wheel width also changes this.

4'' BS on a 8'' wide wheel vs a 10'' wide wheel will be most pushed out then the 8'' wheel.

 

My brain hurts now lol

 

I’m not really sure yet. These wheels are boxed up in a closet. They were an impulse buy with plenty of tread left on my 265/70/R16’s Duratracs on stock wheels.

I’ve been stalking other 17” wheel first gen build threads to see what they’re running but with this information here I guess I need to see what backspace those guys have as well.

 

I have ray10s which are a 8.5'' wide wheel and 4'' BS with a 255/80r17(33x10). fit great. Little rubbing on the pinch weld but all 33s do that.

 

It’s a 7” wheel so the tires won’t be very wide anyway.

 

Yes measurement wise you would be correct. Typically in my experience though, changing the back spacing helps more to get a tire off the frame/uca's but will put a tire more into the fender. Backspacing is a bad way to go about fixing fender rub. Typically fixing fender rub is best suited for an angle grinder, and a BFH.

 

Wow. THat is super narrow for a wheel, even more narrow than OEM. what tire are you going to run? You sure it can fit on a 7''?

 

I’m thinking about a 255/75R17 Falken Wildpeak. That’s a little taller than my current tire and pretty much same width. Recommended tire size according to the literature with it is 265/70R17. It’s the Sema TRD wheel:

 

ahh those are made fore 2nd gen/3rd gen tacos. They have over 5'' BS so will be sucked in more to the truck. Also should be a bit more than 7'' wide, closer to 7.5.

You might rub a bit do to it being inboard so much on the frame or UCA. But would be an easy fix if it did.

 

I wanna see these on a first gen Tundra

 

I don’t know, the paperwork says 17X7 with 4mm offset so it should be 4.16 backspace. If they measure 7.5 that should take it up to 4.41 backspace...if these online calculators are accurate.
