    I’m lifting my tundra just traded in my white 14 for a 19 cement sr5, curious about offset on aftermarket rims my last truck had XD monster 18x9 +18 offset with 295/70/18 stt pro! No rubbing took out the fender caps and mud flaps!

    What I’m wanting to do is the Fuel Vapor 18x9 with a -12mm offset. On a 295/70/18 on toytec ultimate lift would i run into any issues going down in offset I’m just confused and need some help and pics of trucks

    Everything I’ve been researching for 295/70 18x8 to 18x9 is +25 to+45 seems like it would work if it’s lifted 2”
    The +18 pushes the wheel out 2” and seems to be about as low of an offset before it starts causing issues that require more modification.
    +30 seems to be best. Trying to find a wheel I like with +30 is turning out to be hard.
    I was looking at the method MR308 roost 18x9 +18 but I wasnt sure if it would work. Seems like your XD monsters were the same size and worked ok so that’s good info to know.

    That set-up will rub like there's no tomorrow. For that tire size, I would not go lower than +18 mm offset. (I m assuming that you don't want to start chopping off your truck). Mine are that size with 18 mm and my tires are verrrry close to the body mount.

    In my experience with my Tundra and my 4Runner and Tacoma in the past, the main variable to clear a bigger tire is the offset and rim width. I am also running 295/70R18 Nittos RG mounted on Method wheels (9” with +25 offset). I barely have a quarter of an inch left between the tire and the cab mount at full turn. So most likely +18 is the most agressive offset you can use with this tire/wheel set up without having to do a BMC/CMC.

    Well with my +18mm monster they were close but since I took the body mount cap off with both mud flaps I never ran into any issues fill turn or anything. I’m just don’t wanna do any chopping on this brand new cement truck if I didn’t have to do it on my old one. The people at the shop want me to go with a +1 offset and from what I can tell it’s to flush with the wheel well I don’t like the look of that I want some stance just not like a bunch I loved the way my old truck sat they just don’t make the fuel vapor in +18

    +1 won't be flush with the fender, it'll be +/- 2" outside the fender. To avoid a CMC +25 with a 295 70 18. Even with that, since the trucks are all sightly different, you may rub and it'll sit slightly outside the fender.

    Vapor D560's are sweet, I'd probably get them in +1. You sure they'll be flush? I've got +18 295/70R18 and they stick out where I need flares or I'll get gravel rash up the sides.

    FYI. There are 25.4 millimeters per inch, so the +1 offset wheels will stick out a little over 1/2 an inch (0.7") more than the +18 monsters while the -12 wheels will be 1.2 inches farther out.

    I am running 295/70/10 Ridge Grapplers on Method 18x9 +18 wheels. I did the CMC before getting the tires. I also have Icon tubular UCA's. Tires do stick out past the fenders an inch or so

    I think I might do the +18 or +20mm just to play it safe i don’t want to do any chopping since I knew it worked on my old truck and it looked good

    I know your looking at 18’s, these are 20x10 -12 305/55. Just a comparison, I have the relentless cab mounts done. They stick out past my fender just a bit. I have RC flares which are supposed are wider then stock

    Looks great ^

    Wheels would stick out way too far without those flares IMO

    But looks primo with them

    Happy Turkey day.

    Trying to figure out what to do.

    I’ve got 6112/5160 set at 1.9” in front and a 1” shackle in back. Should put me about the height of a stock Pro. I read the pro thread with 295/70/18 no one having issues. I know the offset is a factor here.

    I wanted some BFG KM3’s but they didn’t have any available in 295/70/18 so I checked 285/70/18 They don’t have much in that size. I liked the Nitto Trail Grapplers and they didn’t have it in a 285/70/18 so I figured I’d try the 295/70/18 on method roost 18x9” +18 offset. They clear the cab mount ok but rub like crazy up front. I took both mud flaps off the front (because 2 is better than 1):notsure: I heated and molded the left wheel well liner extension as much I could (53806-0C040) <is that the right part number? I may need new ones.

    The right side (53805-0C040) broke on the way home while turning. I haven’t messed with it yet. You can see where the tire tread is inside the plastic 1/4” or more. :eek:D25CEE4E-7AA5-4F93-B74B-D1A6E3DEA86A.jpg
    When I take the lower liner extension off the tire clears the white bumper cover by a 1/4” or so.
    I was hoping this tire/wheel/lift combo would work. It’s not.
    This wheel/tire/lift combo theoretically number wise should work.
    The 1.9” lift gives clearance to the 1.2” taller tires over stock. The lower offset clears the wider tire of the UCA and res on the 5160’s. The CM is cleared (barely) The lower liner extension is F’ing everything up when turning. If I go straight its fine. If it’s off it’s ok (barley) problem with it off dirt/water/mud gets in where it doesn’t need to be.

    Has anyone made or does anyone make an aftermarket lower wheel well extension piece that will use the same bolt/screws the OEM does but gives the clearance you need while stopping the dirt/water/mud?
    Long question. :help:

    What I would like.

    I would like to keep the 6112’s at 1.9” I like the height and ride/feel of the truck there. I like the +18 stance and the look of the method roost wheels. I wanted as close to a 34x11.5 tire as I could. Seems like I went to big :confused:

    I can try to do a few things:

    I can try to get it aligned different but I think if I move the castor it will start hitting the CM and still be hitting the liner extension. (I do not want to CMC)

    I can take the 6112’s up to 2.5” but I don’t know if that will cause the ride to become stiffer and only allow me to clear things until I stuff the tires while off-road then I’ll be in the same boat. Fine for pavement but not functional off road.

    I can get smaller tires.
    Problem is there is only a few 285/70/18 tires available and I don’t really like any of them. Nitto RG is the only one that is ok. Also I don’t know if the 285/70/18 will clear everything... at this point I’m
    skeptical moose
    3F625C03-53D2-4311-8A71-33609F711AEC.jpg
    I can get 285/65/18 but I was running 285/75/16 on my Tacoma and these would be just a hair smaller on twice-ish the truck.
    I don’t know at this point I’m just thinking out loud.
    Any suggestions? :fingerscrossed:
    Pointers from those who have been here?

    I wish BFG had a 285/70/18 KM3 available right now.
    :sadviolin:

    I believe Coachbuilder makes a front bumper shim. Remove front bumper, add shim and replace. This will give the necessary clearance on the front. Definitely seems like the easiest and most cost effective way to get your clearnce. If you bump the coilovers up to 2.5, the ride will get stiffer but its also alot more work.
