The Great Tire Size Question

First of all, I'd like to thank everyone on the forum for sharing your infinite wisdom and taking the time to help others. There is so much information here, that actually posting a question is almost totally unnecessary. That being said, I installed an RC 2" lift recently and have a question about tires (I know it's been asked before so bear with me). I've read virtually every sticky, thread, conversation etc. on this forum and others and I'm still confused. I have a new set of 255/75-17's sitting in my garage and I'd like to install them WITHOUT spacers. Some say it won't work, some say it will. Some say they've tried it and some say they're currently running it. So, is there an answer to this question or is it one of those things I'm just gonna have to "try"??? Thanks all

I've read that page like 87 times but I know there are threads where people claim to be running 255/75-17's with an RC lift with no spacers, so that's why I posted the question.

More Info

Also, this was copied directly from the Rough Country installation instructions: "This suspension system was developed using a 265/70R-17 tire with factory wheels. Note if wider tires are used, offset wheels will be required and trimming will be required." with no mention of spacers which contradicts the info in the sticky. I'm not trying to be disrespectful, I just don't feel like spending the $$$ to have tires dismounted and mounted just to find out that I have to have them dismounted and mounted all over again.

Well, I must seem like a weirdo for replying to myself but maybe this will help people down the road. I slapped the the 255/75-17's on today (on the Wrangler wheels) using a 1/4" slip on spacer in the front to address the caliper issue. Low and behold, they fit fine with zero rubbing (on road). Think I'll just run it as is unless someone convinces me that I might die using the slip on spacers.

Those specers should be fine. what brand tires are they. Even though you can have two different tires with the same size on the side wall doesnt mean they really are the same height and width. So you will find a few people running a certain size tire without wheel spacers when normally you would need them.

Well, I scared myself into removing the spacers and mounting the tires on the stock rims rather than the wrangler rims. The tires are the stock wrangler goodyear wrangler sr-a 255/75-17's. With no spcers, it only rubs only very slightly on the the sway bar on the passenger side at full lock. So far I'm happy with everything, no problems at all and the ride is exactly the same as it was stock nad it feels and looks a little more like a jeep should.
