I am looking to get Dik Cepek 17X9 Black DC-1's for my '07 titan. I do have a 2.5 in. leveling kit and i want to put on Toyo M/T's LT295 70R17's. What kind of offset should i be looking for? I dont even know what stock offset is and i was told +5 and -5 from the stock offset is the limit. Im not to familiar with "Backspacing". I just wanna know what would work best to prevent as much rubbing as possible and still provide a good ride. Any input will be greatly appreciated. Thanks. Also is the bolt pattern 6X5.5?

Well the stock specs on the 18X8's is 5.5" BS with a +25mm Offset and for the 17X7.5 is 5 3/8" BS with a +30mm offset.

I am currently running a 17X8 American Racing Mojave Teflon wheel with 4.5" BS and zero offset with stock BFG's and they don't stick out to far at all. I have the leveling kit as well and no rubbing but then again you are going a little larger but I don't think you should have a problem as long as you stay away from anything less than 4.5" BS and NO Negative Offset but being that you are going with a 9" wide wheel I would get as close to 5"BS as possible. And yes the bolt pattern is 6X5.5

I think this is your only option in the 17x9, (for the DC-1 rims):
p/n 979412; 17X9; Bolt pattern 6-5.5" or 6 on 139.7mm; backspacing = 4.53”; offset= -12mm

You might need the pinch-weld-mod, (Kartman's). with a 9" wide rim with 4.5" of backspacing. I'll post a pinch-weld-mod link in a minute ... looks easy and fun. I heard of someone with Nitto TG in a 295/70/17 and Moto Metal 951 with 4.5" backspacing needing it.

Since the backspacing is the same as yscty's but these DC rims are 1" wider, that means your DC's will stick out an inch more ... a hypothetical 8" rim with 3.5" of backspace would stick out the same amount.

Btw, yscty is correct that a 5" backspacing, (0mm offset on a 9" rim), would have less chance of rubbing the inner fender when turning.

Ok if i add a 6" lift and went to 35X12.50R17 will i still have to do the mod?

Yea, more than likely. It's not a big deal though. I had a lot of the pinch weld done when I got everything installed.

My friend has a Procomp stage1 lift and Moto Metal 951s with 4.5" backspacing, and runs BFG MT KM tires in a LT35x12.5x17, and he had to do the pinch-weld-mod, but not too much material removal was needed. Probably not that much would be needed with the 295s and a level kit either. You might get lucky and not have to cut at all, but bottom line ... you need either more backspacing, or a narrower rim if you for certain don't want to cut.

^^^^^^
Agreed 100%. You might get lucky but be prepard to cut a little if your not so lucky.........

Hey man. I just put the ProComp Stage I on my truck and ended up buying brand new wheels because the spacing was off. I put 17" Helo Maxx6 rims on about two years ago. Took it in for the lift, the mech said they would fit, get a call later that day. he tells me the lift is on but the wheels dont fit. So i was pretty much SOL. I ended up buying the exact same rim but 18"s in order to fit. If cutting was an option, we didnt eve talk about it, i just dished out the cash and put the old wheels on craigs list. so take my mistake for what it is. i just strongly suggest double checking with a mech about the fitting before you make any purchase or major mods. :cheers:

Well, sounds like your mech didn't steer you in the right direction. Some know their stuff, but most don't.

You'll get way better information on a model specific forum like TitanTalk.com 99% of the time, IMO. Even with Titans and so many variables it's tough, but for a general mechanic, having to know all cars and trucks, plus various lift and lowering options ... no way.

So your 17x9" or 17x8" Helo's had a 4.5" or 4.25" backspacing? And you 18x9" Helo's had a 5.75" backspacing ... [visa-versa if your new rub was at the new PC spindles, i.e. you had 5.75" and went to a 4.5], that's as much as an inch and a half in just backspacing. But the 17s are also offered in a 5.75" backspacing, so wheel diameter had nothing to do with it for fender rubbing. How many mechanics will be able to explain that, unless they have the same truck.
