Hey guys, I've got a question about fitment on the BBS RD truck 17's. I've got about 3" of lift in the front. I've already trimmed inner fenders to fit 285/60/18 on

Moto Metals. Does anyone know if the offset on the new wheel is going to rub the cab mount or anything else with 285/70/17? If I'm correct it should be taller than my current setup, but a little bit skinnier. Also who's got pics of these on a SWB?

Here's my truck

I forgot to add I've been told that I will have to cut the cab mount. If I run say a Spidertrax 1.25" spacer will this alleviate my problem?

The overall diameter of the 285/70/17 is theoretically 1.25" larger than the 285/60/18 setup, which means you would need a minimum of another 5/8" clearance between your current setup and the cab mounts to keep from rubbing. The width of the tire will remain the same, only the height will be affected. (note that tire sizes tend to be nominal and actual dimensions can vary based on brand, tread pattern, etc. so keep this in mind if you are planning on changing to an entirely different tire)

My suggestion for checking if you will have enough clearance with 5/8" increase in radius would be to cut a strip of 5/8" thick plywood (or whatever material is readily available and easy to cut) say 2-3" inches wide and long enough to span the width of the tire. Tape this block to the tire in-line with the cab mount to check for clearance between the cab mount and the block of wood. Then turn your steering wheel through the full range while checking for clearance. You could also try finding a ditch and pull into it at an angle in order to compress your suspension and repeat the same process to check for clearance at multiple ranges of suspension travel.

I'm basically talking about offset here because the Moto Metals stick out further than the BBS's are most likely going to. I have a set of BBS Rw's on the truck right now, with 265/65/18 so I can't really do any measuring or anything.

It would help if you could provide the width and offset of both the moto metals and the BBS's in question. I would assume they come in more than one size in regard to width and offset.

I'm not sure of the offset on the BBS's. I know I've seen these on lifted trucks, but not sure if they are running spacers or not. Anybody with these wheels? I think they might be the same offset and backspacing as TRD sport wheels, but I'm not sure.

Those are the Rw's. I have those on some 265/65/18's right now. I'm getting the Rd's in 17's tomorrow. Painkiller, what size tire are you running? How big of a lift? Are you running spacers? Those look really good on there!

275/70/18 Toytec Ultimate 3 in with Total chaos upper control arms. Everything fit great with no rubbing. Until......I thought I liked the look of the wheels sitting out a little bit more and put spydertrax spacers on and then the fun began! Cab mounts cut, ALOT of the inner fender wells on both sides, and I still need to trim more! All was fine until the damn wheel spacers.

Hmmm, I'm getting mixed answers on if I'll have to cut the cab mounts or not. I guess I'm just gonna buy the skinniest 285/70/17 I can find, or just go with 265/70/17 for now. I should recieve the wheels today. Can anybody point me in the right direction of the cab mounts cutting thread?

Where are you getting the 17" RD's from? The BBS website is showing that they are only available in 20" and 22"...

Painkiller: Nice setup!:thumbsup: Could you post or PM a front view shot of your truck so I can get an idea of how the spacers affect the stance?

Bought them from a guy with an FJ.

No vibes, drives like stock.

Ok guys I found out these wheels are 17x8 w 4.75" BS +5mm offset. Any input if these will fit with 285/70/17 with or without spacers?

With 4.75" BS and 285s you would most likely come dangerously close to having the inside of the tire constantly rubbing on the spindle/UCA. If you're ok with using spacers, a 0.25" or 0.5" spacer would be ideal even though I'm not sure that those are available.
