255/85 on stock suspension

05 Tacoma dbl cab with stock suspension. If I go with a shorter backspace on a new set of 16" wheels, say 4.5", then can I fit the 255/85's without rubbing, or making other modifications? Looks like they add just over an inch to the radius of my stock 265/70's

 

265/70/16 are 30 1/2" tires , 255/85/16 are 33 3/8" tires , not sure if it will happen without a bit of trim a roo , and pushing the tire out will actually increase the likelihood of a rub with 255's

Ya..read a lot of those posts, ultimately leading me down this road for 255's. I'm not quite ready for a lift and didn't see anything about these on a stock ride.

Where is most likely to rub in turning situations?

 

A few members on that post noted that they do not rub with 255/85s on a stock rim at stock height. They also noted that they stay on pavement.

 

May or may not be going with 255/85 before lift, stillundecided. But first…if I go from a stock 7” wheel with 5.25 BS to a new 8”wheel with 4.5” BS then my centerline of wheel is moving out 1.25” (thoughstill inboard of hub mounting plane) and the curbside face of wheel is movingout 1.75”, which means even a 255 tire will break the vertical plane of thefender. I’d prefer the tire to stay within the fender extents, but finding anappealing wheel with 5+ BS is not happening. Appealing to me is the basicdesigns such Mojave ATX, Procomp 7069, and Black Rock Yuma. And, I’m not clearif the added 1.25” outside stock mounting position is potentially damaging tosuspension.

 

Rubbing may occur and you may have to trim a little but not a ton. The lift will have zero effect on whether you rub or not, the wheel travel is exactly the same stock as it is in a "Lifted" application, only difference is the ride height is a bit higher when preloaded so you wont rub as often on the street but will rub in the same spot stock as you would lifted. The only lift that changes the suspension geometry is a drop bracket and I assume that is not your intention since you are considering this size tire.

 

i dont think that would work out, i have 255/85/16's now and i rub on full lock and thats with a 3" lift

 

ok, though not sure I follow how a lift will not change travel height...lift and rubbing and travel aside...even if I ultimately use stock tire size, will the differing BS and wheel width cause issues with pushing the wheels further out over the hub mounting and beyond the fenders

 

The "lift" is just an adjustment of the ride height, the front suspension is just pushed down a bit when you run a preloaded coil or adjustable coilover. The suspension cycles within the same limits top to bottom it is only the static height that has been changed by the coilover preload. When you compress the suspension while turning is when you will typically rub, this compressed position is exactly the same whether stock or "lifted" With stock wheels and offset you will have the least rub because the turning radius if farther inboard than most aftermarket options. The issue is you may rub a little at full lock whereas with a wider offset you may not. The wider offset will cause you to rub in areas such as the fender flairs and possible the cab mount. It is safe to assume you are going to rub a little somewhere but not a ton, the aftermarket wheel option with a 4.5" backspace will likely be the best bet and only rub areas like the flairs which are easily trimmed.
Some of the TRD wheels like the Trail Teams, Baja and TX wheels are a 4.5" BS on a 7.5" wheel and likely the best possible combination for this tire size.

 

thread revival, woo!!

anyone else have experience with 255/85-16 or 255/80-17 on a stock suspension??

 

Try them out! I loved the look of them! If you rub I believe it would just be the mud flaps. All I ran was eibach coils! Buy them from me!
