35" Tires

[AlexJet]

I was wondering what is the maximum tire size you can put on 4Runner. I always thought that with 3" suspension lift 275/70-R17 will be the maximum size without metal trimming. Then I found that couple members put 285/70-R17 with some metal trimming. But what is the maximum???
As far as I know FJ Cruiser has the same suspension, so everything it has will be the same to latest 4Runner. But look at this... How the *** All-Pro managed to fit 35" there? This FJ has only 3" suspension lift (coilovers). I want them on my 4Runner, but how....???

The FJC seems to have slightly bigger wheel wells. However I think the biggest difference is the fact that the front steering on the FJC has been reduced, look at the turning cicrle of the FHC compared to the 4R.

Besides they had to trim the front body mount on FJCs as well to fit larger tires, something you can do on the 4R as well.

So if you want to run 35" trim your body mounts and dont turn the steering wheel full lock ;)

[AlexJet]

So trimming body mounts is the only way to do it??? Is that dangerous?
How much they reduced steering? That's interesting....

Well that is what all the FJC folks seem to be doing. I think it is fine if done correctly by boxing the frame up again. There are various pics on ih8mud and fjcruiserforums on how they did it. I don't think you will fit 35s without trimming, unless you changes the suspension to something very different like TC.

Look at the turning radius of the FJC compared to the 4R and keep in mind the slightly longer wheelbase of the 4R.

Search around a little and you will find all the answers you are looking for. r0cky did run 35s for some time. I would personally not do it till I can regear, the performance in hills and with a heavy load will suck with 35s wihtout regearing. Even worse if you have a V6.

[AlexJet]

I do have V6. :)
I'll look at those forums more carefully, but so far I didn't seen anything there. May be I missed couple threads there.

[chiefiji]

lance is running 35's i think too, with a bit of modification tho :rotflmao: i'm sure you'd be hurting real bad with the v6 + 35s.

Try this thread. Scroll down and you will see what I mean by trimming the body mount. Edit: Might help if I include the link.

If you have the V6 with the 4spd, forget about 35s till you get gears. Look into 33s, even 34s will be pushing it IMHO.

Here is a really nice write up the body mount trimming

I've 2005 V6 with 5spd (transmission is the same as V8).

The link did work. I think their server is down.

I'll look again tonight, but the link should work. Looks like MUD is down a bit.

I ran 35s for awhile - it took a good amount of suspension lift, and a body lift ... and a LOT of grinding on the frame and around the body mount. Even then, it still rubbed and every time I went off roading with them, I felt like I was going to break something. The 275s I ran/run are far better feeling. If you can re-gear, go for it and see how you like the 35s.

I don't think that even Lance stayed with the 35's and he has long travel and fiberglass. To some extent, if you don't have the system to support 35's, you'll only do yourself more harm than good. It's not worth the extra 1 inch clearance over 33's.

:iagree But planning for 35s are good. You dont want to revisit mods in the future to run larger tires. Gearing, etc is important to keep in mind. As some guys have run 35s on the 3rd Gens with relative success I'm sure the 4th Gens and FJCs will hold up OK with 35s if done properly. One thing is that doing high speed desert driving the tire will probably rub the inside of the fender at the top, unless you have a body lift and drop the bumpstops a bit.

r0cky do you know the specs of the wheels you used with the 35s on?
I think wheels will be very important when fitting 35s on the 4R. I think with the right BS, width and offset it might work. Or alternatively do 34s (305/70/17) they are a bit smaller than the 315/75/16 or 315/70/17 which is generally regarded as 35s.

I think it will require a bit more testing and R&D to come up with a good formula. The problem is different people use their rig differently, so what works for one might not be the best for another.

The wheels I was using were American Racing Bajas ... 0mm offset / 4.5 backspacing (if I remember correctly).

Were they the same wheels you are using now? AR 17x8 are normally 4.5 BS and 0 offset for our wheel pattern. If that is the case you will have the most experience (read pain :P) of figuring out how to make them work. Might have to bug you in terms of metal trimming required then ;)

agreed. 35's are a big step in mods to do it properly. Making it work on a Starbucks run and a real trail run are totally different.
