255/80R17 tire size

This is my setup. I think these are the trail wheels. Fits perfect with no spacers.

 

+15 is the offset of your FJ/trail wheels. From the looks of the reuslts the position of the tire is only slightly inward and most of the girth your losing in tire width is on the outside..

 

Looks like I am going with 255/75/17 - I don't want E load, so I can go a tiny bit smaller and get Toyo AT3s in C load. I've got a Pro with Pro wheels ('24) so I think I would be struggling with the 255/80 anyways. 275/70 is the only other option I am considering.

 

I was in the same boat as you, I considered skinnies but I like better the width of 265 and up. I wanted C load tires (absolutely didn't want E load).
Also didnt want to modify anything suspension wise for now (might get a small lift eventually with Eibach springs).

I started looking into 275/70 because its the perfect width IMO (not too wide, not too skinny) and slightly taller than stock without worrying about any other modifications (BMC, UCAs, etc..)
as far as I know wildpeak falken are the only ones that comes with load C in that size. I chose AT3W over the new AT4W because several people have said the AT4W are slightly worse in the snow and also I was able to find AT3Ws for $250 cheaper for 5 tires.
After install and alignment I had very minor rub at full lock in reverse. Most people wouldnt care but since I do offroad often and need all the space for articulation I trimmed ever so slightly the front fender for peace of mind (not noticeable).

I had them for about a few days and really happy so far. IMO all the offroad trims should have came in at least that size

Check this thread if you want to see pictures. I added some as well a few days ago

 

Just looked at your pics - those look great.
My big gripe is the Wildpeak AT3W is the weight. 57lbs vs 48lbs for the Toyo.....that's E load range weight right there.

 

…but this story is far from over

I’ll be posting my “nightmare” after I affirm one more event…

Side note:
Headed to other thread with this…what have you done today

 

Yes, anything that is not SL in a 275/70 is going to be heavy compared to pizza cutters. Even more more for the Falken Wildpeak like you said. I didnt care much about weight (even though lighter is obviously prefered).
My main concern with the E load was how stiff they ride compared to C load

If that is a big factor for you then skinnies are definitely better in that aspect.

 

clean clean clean rig! Looks just awesome

 

Thank you!!! It's a bit different that most setups but I love it.

 

Why does no one make a 255-80 in c

 

Too much sidewall flex.

 

But you can get a 33 10.50 in a 15 that's not too much wider and would have at least equal if not more amount of sidewall

 

My guess is because there is no market for it. Aside from a few of us goofballs who like skinnies on our trucks, the size is typically used on work/ utility trucks. They don't want a C-load tire for what they do.

 

What bumper is this? I love it!

The 255/80 was made for dually trucks, to have 3/4 and 1-ton capacity. Look at the rear tires of a F350 or F450 dually. That's the point of the 255/80, and that requires a stiffer, higher load carrying, sidewall.

 

Swore there was a pic in the thread showing the clearance of the spare, I think someone with KDSS(which I have)…put mine back up finally n it is free/clear but close

wondering if grinding down the back of hitch is a thing…might gain +- 1/4”

 

My 255/80 AT3W's on my Runner has officially come to an end. A screw went into an unpatchable area, and since they are no longer being produced I had to decide on tires on the spot. I only had 1 OG AT3W left, 2 were warrantied out due to tread chunking off and the 3rd was my fault slicing a side wall on a rock. My OG tire had 58k miles and was at 6/32's, honestly had plenty of life left. Ended up ordering the Toyo Open Country RT Trails. Was debating going with the 255/85 Baja Boss' but didn't want to deal with fitment issues since it is my winter DD. Maybe next time.

 

Did you go with the same size this time

 

I did. Love the 255's

 

255/80 Open Country RT Trails

 

Looks good I decided to change teams today lol pulled the trigger on 285 70s

 

The guy at discount was trying to talk me into 285's lol

 

I couldn't say no four brand new ko2s for 600 bucks

 

That is a killer deal

 

Yeah

 

You gonna get a spare?

 

Was thinking about just using a 255 75 for a spare.... Unless you have any thoughts

 

Are the new KO2's 255/75? If so, have at it. If the 75 ratio is a different number, your differential (and your wallet) will hate you.
