I have a stock 2007 4 door Jeep jk Sahara. Yesterday I put a set of 275/70/18 Nitto Crosstek on my 18 in stock Sahara wheels. I am a Jeep newbie and have no clue what I am talking about but a little help would be excellent. I want the tires to stick out a bit further than they are currently. I am assuming I would need wheel spacers but not sure what size I can get. I saw 1.5 in spacers is that the biggest I can go and if so will they fit the bolts?

 

1.5" spidertrax seem to be the best choice.... They will fit your factory wheels just fine, and are hubcentric..

 

Yup 1.5" spacers will do. Rough Country and Spidertrax are the biggies. Many on here will scare you into thinking that you will surely be involved in a horrible accident (spacer failure at highway speeds) if using the Rough Country spacers, which cost less, but in reality there are thousands of people running them without issue. I was one of them. The RC ones are plenty strong when installed properly, but the SPX ones are significantly stronger. To that argument, do you want to push against hard steel or really, really, REALLY hard steel? Answer - you'll be perfectly fine either way.

 

Actually atleast the Spidertrax spacers are aluminum, not steel

I'm sure you would be fine with the rough countrys (as has been pointed out, about a zillion people do) but I went with Spidertrax because that was one place where I absolutely did not want to compromise. It would be tragic for something to eventually happen and then wonder why didn't I get the best I could??
