Put 255/85/16s on stock OR wheels and suspension

Are you hitting your cab mount? I needed Spidertrax after I installed my JBA UCAs but now I’m slightly rubbing the cab mount. Going to a different shop tomorrow to verify my caster is high enough before I CMC.

 

1) IFS ride height lifts don’t help you fit larger tires unless you do not intend to use your suspension’s full range of motion (E.g. slow down to 2mph for speed bumps).
2) Many people report success in fitting 225/85r16 without any modifications.

I have 255/85r16’s on stock wheels without any trimming and I have experienced what sounded like rubbing twice. Both times I was turned hard to the left and dropping off a 2-3” ledge of sand. I debating getting a new alignment that moves my wheel forward a bit.

 

2” is about the limit for an IFS ride height lift on a 3rd gen. We only have 3” of down travel from the factory. Beyond that you need to go to a drop bracket lift which is a whole different ball of wax. There are many options and many threads on here.

 

Thus wheel spacers are illegal in Australia.

 

Great looking truck! Nice and simple

 

nope, clears the cab mount fine. It’s rubbing on the mud flaps again slightly, but I’ll take that over the UCA.

 

That gives me hope I can get it cleared without a CMC. I had to cut some of the fender flare that it was hitting but I can definitely see some rub marks on the cab mount solely on the passenger side. Fingers crossed a better alignment can get things right.

 

I know the 255 with fit stock suspension with factory wheels but will they work with factory or aftermarket mud flaps? Just doing my research going to pull the trigger on tires before winter. I like to run flaps in the winter due to the salt and gravel they throw on the roads around here.

 

That's a mixed bag. Depending on the specific 255 you choose, some have reported issues with mudflaps when articulating or stuffed. Some have been able to fix it with aftermarket UCA's, some haven't. I'm not trying to dissuade you, this is just my knowledge from following this thread for some time now.

 

Thanks for the info. I think I’m going with this size tire no matter what. I loved my 255/80/17’s on my second gen. It was lifted though. I’m not sure I want to lift this truck. But the extra ground clearance from the bigger tire would be nice. I’m not afraid to rub a mud flap or even have to change from the stock ones. Just looking for peoples advice. I think I’m going with the cooper st maxx. That’s what I had on my second gen but I’m also considering the toyo mt and the km3 but I’m worried about the straight up mt since I will be using these all year round. They will see snow and ice. I am using my truck for work and I work for a company that owns multiple rock quarries so I’m on rock, gravel and mud a good bit.

 

so happy I stumbled on this. Now I need to read through the whole thing. Unfortunately the tire options in this size seem a little limited, none of my go to A/T tires seem to be available.

 

It looks like there are more options in a 255/80/r17 size...
If you were gonna buy wheels anyway, would it make sense to go a 17"?
Maybe a 7 or 8 inch with 0 or negative offset?

 

The 25 offset is what makes the 255’s possible on stock. Shift much from that and you may end up rubbing.

 

I'm still digging through the 139 pages, but I eventually am hoping to swap to some the TRD pro wheels which are +13mm. I haven't seen anyone with a set of those + the narrow 33's yet.

EDIT: stumbled across https://www.tacomaworld.com/threads/stock-trd-pro-with-255-85r16-cooper-discoverer-st.465472/page-2 and it looks like I'd probably be able to go with the 17" TRD pro wheels which opens up a few more tire options.

 

I'm on the fence myself. Almost pulled the trigger for the T4R Pro wheels during the 40th anniversary sale. I don't want E's, might accept D's (I think Toyo or Nitto might have a D in one of the sizes I'm considering), but would prefer SL. I'm leaning towards working my up... starting with 265/75/16 first.

 

I didn't jump on a set of T4R wheels (with new tires) on craigslist earlier this year because I thought $1k was too much. Now I'm regretting that a little bit haha.

I think you should just jump on the size you think you'll go to. I unfortunately need to fit in a 7' garage so between tires and my 23" camper shell on order I won't have a ton of room to play with.

 

What's the functional advantage of skinnies in the absence of a rubbing issue? Is there a weight advantage?

Regards,

 

There's an argument for 'not floating' when compared to 285's or 305's in situations where that's better; i.e. cutting through snow to the traction beneath. There's also a really good description of the change in traction when airing down. The tall skinny gets you a longer and narrower contact patch compared to fatboys, which allows the tire to grip rocks etc better. I wish I had the link handy. It's one of the expedition portals where he goes into the science and physics. Pretty good 10 minute read.

I’m getting 255/80/R17 Toyo ATIII’s mounted Friday on 4-runner pro wheels. Truck lifted 2” with SPC UCA’s. Hoping for no rub and/or minimal trimming. Also, tires are ~52 lbs for true 33” E-load. Most 285’s are closer to 60 lbs and have more rolling resistance and around 32.5” tall.

 

Yeah. I might just switch to skinnies. I recently went off roading in my 31 P-Rated tires.. I just don't feel confident going over large rocks.
