Goodyear Wrangler 285/75/16 with Donahoes

[Box]

If this is your setup:

How close are your 285/75/16 goodyear wrangelers to your UCA with Donahoe coilovers? If it's less than half an inch will they ever rub, or do they move synchronously?

What about your BFG A/T KOs? They seem to be a little narrower...

I'm having issues that seem to be in the range of 1/8"-1/4", and I'm curious if they'll ever rub or if they'll keep their distance.

The tire will get wider as you air down, if you hit/press the top of the tire hard enough into an obsitcal I guess you could rub. At that time, what does it matter, its not going to hurt much besides paint.

Do you have stock UCA's? What height do you have the Donahoes set at? Backspacing on rims, bla bla bla.

From the information you provided, they shouldn't rub. 1/8" is pretty close. I can't remember how close my 33x12.5x15 BFG MT's were to the uniball cup for the camburg UCA's... but I never noticed any rubbing on them. I routinely aired them down to 10 psi and never had issues that I know of.

My donahoes are set at around 2.25" of exposed coil. backspacing is stock on 2003 rims - about 4.25 I think. Yeah we're talking really close, but if it sits 1/8-1/2" away from the UCAs, it will ALWAYS stay that far away, right? so if its not rubbing when I put 'em on with the lugnuts, then it really won't rub unless I air down a lot, right?

You should be fine. You can always air down and check.....

And 4.5" is stock b/s.

I put 'em on! So anyone who wants to know...

2003 Toyota Tacoma Xtracab V6 with Donahoe coilovers set at 2.25" of exposed coil, deaver 8-pack and bilstein 5100s with 285/75/R16 Goodyear Wrangler SilentArmor tires works OK. When it's on the lift it rubs, but you can still turn the tire (I could slide my key with the tire in between the two and it would barely scratch the a-arm, but it still rubs). Once it's on the ground, the A-arm lifts up just a little higher than the tire leaving you with about 1/8" of clearance in between the a-arm and the inside wall. all in all they drive great & fit well - super stoked.

The standard measurements for this tire is 32.8" diameter, and 11.3" section width. The BF Goodrich tires run a little narrower by about .3-.5" on both measurements.

Hope this helps anyone else that's in the same situation.

So I hate to raise the dead, but this post has all the info in it already.

I'm now looking at putting on some new wheels with less backspacing (I'm still running the stock 16x8 TRD alloys).

Is a spacer a good option (or is it even possible)?

Are there any negative effects of decreasing backspacing? I imagine too much decrease in backspacing would increase stress on the suspension, and I could then see why a SAS would help (beyond that, nobody's ever given me a good explanation of why it's done other than "one day, son, you will know why").

Any good recommendations on some 16x8 wheels with about .5" less backspacing from stock?

Do the stock 16x8 alloy wheels sell well used? Some of these steel rims are so cheap I think I'd make a profit and I could do more additions.
