I've done a bit of searching, and maybe someone else can help with that.

Who has installed 35x12.5/315-75 tires on a 7" wide rim? I'm curious as to looks and any bead seating problems. I know recommended is 8-10" wide wheels, but I want to try and stick with OE wheels, which all seem to be 7" wide. Any thoughts or pics?

 

I ran them for two years on a 4runner i just sold. The tire shop didn't have a problem seating the bead, i don't see why there would be an issue seating the bead. I feel like putting them on a narrow rim is like a cheap bead lock. Iv run them down to 8psi out wheeling and drove home on that pressure. You will need to run less pressure even when street driving in the 4runner i ran 25-27 to get even tread contact with the road. If you do go this route, mount them up and drive on dirt then pavment. The pavmant will take the dirt off where there is contact with the tire, adjust your pressure from there.
I didnt just run around town with that set up I visit friends and family in my home town two hours away almost every other weekend, so i would say i put 20-30K miles on them with out a problem.

 

there have been several here who've done it. i loved those wheels when they were on my truck, but i knew they wouldn't clear 33x12.5s on my IFS so I sold them

first YTer that comes to mind is AxleIke who had 35s on his IFS 4runner with the stock alloys. only issues i could see is the contact patch being rounded unless running low psi to compensate, and the extra sidewall bulge that might cause clearance issues (definitely not clearing on IFS rigs without some mods). on the plus side, you get the extra sidewall bulge to protect the wheels and it'll act like a cheap beadlock because it's always pushing on the wheel due to width. also, there may be some issues with warranty claims if the tire isn't on the proper width wheel - but i'd guess it's up to the shop you buy/install from?

to toss another option into the mix, IIRC there are still companies out there who will take your OEM alloys and turn them into real beadlocks. it's definitely not cheap, but can be done and they look fantastic! i'm not quite sure on this, but I think they add the beadlock ring and extra channel to the outside of the wheel, thus making it closer to 8" wide.

wouldn't everyone love this? HELL YEAH!




oh yeah, and if you keep the OEMs, you may want to look into doing this :

 

They don't look to bad. I quite like it.

Although, I travel with my truck, upwards of 50-60K miles/yr. So I'm wondering about the tread wear and evenness.

 

The tread wear can be compensated with lower psi to get even contact patch, but the downfall I see is (depending on what tire you get) you could be fairly squirrelly on the road due to sidewall flex from the low psi. At that many miles/yr I'd personally consider a 2nd set of on-road tires.

 

I'm running KM2s now, and they wear like iron. 70K miles and they're not even halfway worn yet.... And I believe in the "Run what ya brung" mentality, I don't trailer my truck, I drive it for work, I drive it to fish, I drive it to kayak, I drive it to the store, I drive it everywhere my body needs to be. And I don't care about noise from the tires so much. I have a loud stereo to compensate for that. Besides, it's almost a 30 yr old truck, so its gonna be somewhat noisy anyway.

As far as tires, I was leaning towards Toyo Open Country MTs, but they are on back order forever, and I would have to get different wheels(no 35x12.50R15) to get 315/75s or 35x12.5R17. I'm going to a larger tire since I'm running 4" of lift with longer shackles and it looks kinda funny with skinny 33s on it. If I could find a good 35" pizza cutter(my style), I would be all over it. But nothing works...except Swampers. So...

I've been eyeballing the Cooper STT, but get mixed reviews, and its not a very heavy ply tire like the Toyo. Which is fine for my truck, but it'll also be softer if I go lower tire pressure with the skinnier wheel situation.

 

I did run the stock alloys with 35's. No unusual wear pattern, but I only ran them at about 30-35 psi, to avoid bulging in the middle. For better mileage, you'd want to run them at higher pressure.

 

I know they aren't 35's, But I did run 33x12.5's Durango MT's on the original 15x7 alloys for years with no ill affect. I did run them at 30psi for street pressure to ensure even wear, and even aired them down to 10psi off road. As a matter of fact I am going to put the same tires (still have) on my 90 4Runner that I am working on right now.
