Do you have fender flares? If it is stock...Id say the widest you can go up front would be 8-8.5. 8 inch wide maybe +40-45 offset and 8.5 im not sure. In the rear 9.5 +50-55 offset. What size were you planning on? Depending on how the rim is actually set up, the lip sizes would be different. I have a set of Jline 19's and I only got around 1 inch up front with a +45 offset and around 1.7 inch with a +55 offset. I believe I could have went a tad lower to get a bigger lip but according to the design, that's about how much lip I can get. But, some others on here has the Iforged with same sizes and manage to get a lot more lip than mine. The hre has a simlar design to the jline 5rl3...it might be the same but I never know.
Search for jline 5rl3 and you will find my pix...
