    Biggest tires?

    Does anyone know what are the biggest tires (height and width) we can fit on stock RRC rims? I've got 30.5" now and I'd like to go to 33"....

    a 31" is about what you can fit stock. To go to a 33" tire you'll need at least a 2.5"
    lift with trimming. 255/85/16 is a great size. However most run a 33's with a 3" lift and minimal trimmage of the body.

    245/75/16 is about a 31" tire standard would be 31x10.50
    265/75/16 is almost a 32" tire standard would be 32x10.50
    255/85/16 is a full 33" tire depending op tire company and standard would be 33x10.50

    I have a 2.5" lift for the moment, and I'm riding on BFG A/T 245/75/16. Although I dread the thought of buying new rubber when my tires are good and I have a full size spare that's never been used...We starting trailing with a more experienced group and feel (specially in the snow) that my tires are too small. I have a buddy with 33X12.5 on his Tacoma that pretty much gave in so... but they are on 15's. I didn't think we could get aftermarket rims for Rovers (at least not readily around here) but I guess I'm wrong.

    In any case, I'll look at the 255/85/16. Thanks!

    "Typically", the evolution of lift/tire size is ...

    First: 2 inch lift (Old Man Emu) with 32" tires (265/75/16 or 235/85/16)
    No trimming or drastic modifications required.

    Then: 3 inch lift (RoverTym) with 33" tires (255/85/16 or 285/75/16)
    Slight trimming w 255 tire. More trimming w 285 tire. Modifications recommended.

    Any of those tires will fit on your rims. I believe adding an LT230 transfer case with 32" tires will increase your trucks off road capability more so than going straight to a 33" tire with the list of recommended mods.

    Weird. I get ZERO rubbing with my 255/85-16s on an RTE lift with not trimming.


    I did have the 255/85-16s on with my 2" lift, but John is right, that does require some trimming or just not ever leaving the pavement.

    Agreed.

    I hope! As I'm about to go to that size. Maybe with the perfect spacing of the axles on the arms, It will fit without trimming. Really want my 4:11 gears installed before I do.

    Would 255/85 R16 fit a RRC with OME heavy lift and 30mm wheel spacers?
    When my current tires wear down a bit more I'm hoping to bump up a size but I'd like to avoid body trimming. It would be nice if I could fit 33s without a body lift.

    I don't know if the wheel spacers will help or not (I'm guessing not) because width really isn't the main problem with an OME and 255/85's, the height is.

    I had 255/85s on my truck with a 2" lift for about a week while waiting for my RTE springs. It drove fine on pavement, but I never took it off road.

    John,

    These pictures were taken with 255/85-16s with a 3" RTE lift and zero trimming. None of my tires were rubbing front or rear.

    That's cus 255's are only 10" wide and work great on a Rover I am running 33/10/15 BFG's on my RRc and did no trimming either... but as John mentioned a 285 or 12.5 will need some trimming and possibly spacers almost a given on a stock Rover wheel.
