33 inch tire vs 35 inch tire...

Jas12682 [OP] · 08-22-2007, 01:54 PM

A lift and tires are on the horizon for my fj, in regards to the wear and tear,
how much more damage does a 35 inch tire cause compared to a 33 inch tire?
thanks for your comments

a 35" tire will stress the vehicle a lot more than a 33" tire will.

You will need to do some mods to the wheel well as well with the 35in. tires.

Ask RockCrawler about what has been done to his rig to get 35's to fit. I think in the end, that truck went back to 33's cause it just wasn't worth the hassle. 33's will also decrease the amount of articulation that you have.

Going to 35" depends on whether you want the tire to fit under all circumstances or just for street / light offroading. The 33" is the biggest tire that can fit under all combinations of turn, stuff, and weight distribution. Check out my experiments.

If going with the 35" tire, you will need to re-gear too. All-Pro sells what you need for re-gearing. I will tell you it's a little expensive, ARB front locker, new housing, gears, about $3,500. You will more than likely need to go to a bigger brake too to stop the extra rolling weight. Just my 2 cents.

35's will most likely result in considerable stress to your CV's if you plan on wheeling your FJ much; much more than 34's (or smaller) will (not to mention the added clearance issues). A number of people are running 35's, but probably not for a long enough period of time to reliably test the durability of CV's while running them.

I'm running 34's and while I do like them, my next set will be 33's. I still get some rubbing at full compression when rock crawling.

With the 2.5 or 3" suspension lifts that many of us have, some 35"s won't fit, even with the body mounts chopped. I tried 35" Toyo Open Country MT's with no luck. Ended up with 33"s - kinda glad that I had to go with 33"s ... save on wear and tear.

Although I agree it's a challenge, I went with larger tires than these and have had a stable result after wheel well modification. I have 315/75/16's on 4" backspace (so they don't stick out as far as the 3.75's and don't require as much front wheel well. I've trimmed but not removed the fender flares and trimmed the body sheet metal. I have a 3/4" bump stop drop in back which will soon be removed to see if I can reclaim that up-travel without contact.

35's for full offroad capability are do-able, if you're willing to work for it.

I agree that you can make a 35" sit inside the well for any combination of turn and stuff if you cut, pound, chop everything for a vehicle so long as the vehicle load is evenly distributed (e.g. vehicle is sitting on level ground). The problems come when you roll much of the weight of the vehicle over on to one (maybe even turning, front) wheel. That wheel gets pushed back and into the frame in a number of places (see my photos). This clear fit maximum is about 33 ish " and is not very dependent on tire width. By 35" there would be significant frame interactions. These possibly could be limited by stops that limit range of turn and or stuff. But the (surprising) bottom line results from my tests were that even savagely chopped / cut / removed mounts, wells, and fender flares still limit to tires just over 33" in some perverse (but crawler encountered) situations.

As usual, I'm happy to be proven wrong in well photo-documented experiments, such as those shown on my other link.
