i have a flame red Rubicon, and i want to out a set of 34, mud grappler on my jeep, and i want to have it so its 10 in wide at least. and i mean i dont know to much about wheels and tires, but does anyone know a good set of wheels for my jeep that would work, black wheels and even if 34s will fit on my stock Rubicon

 

34s aren't going to fit without some sort of lift and/or a lot of trimming of the fenders, if you leave it at stock height. Also might rub with stock wheels without wheel spacers (spidertrax)...

As for a 34" tire (295/75/16, 305/70/17) that will work under the above circumstances, you generally will need a 16x8 - 16x10 wheel or a 17x8 - 17x10 wheel with at least 4.5" of backspacing. A 15" wheel MIGHT work if you get it with 4 or 3.75" of backspacing, but read around what works and what does not in 15". General rule is 16 or 17" wheel is safer to run without hassle...

Look around and search and read, but some of the more common wheel brands that will usually work for you are pro-comp, cragar, aev, blackrock, mickey thompson, etc.

 

I agree with redrockin7 - 34s would take some modifications. I stuck with a DuraTrac 285/70/17 (equate roughly to a 33x11.5x17) on Black Rock rims with a 4.5 backspace, as this was my first major upgrade and I didnt want to have to worry about rubbing and such. I get no rub at all sitting completely stock on a 07 Sahara 2 door. Didn't have to worry about trimming anything as well so this size worked well for me.
