So I've decided on 27" itp 589's on itp ss108 or 112 in black. I'm still trying to find the best price. So far it's 835$ shipped, let me know if you find better within the next day or so. I chose the 589 over the xtr because there a little lighter and I can't find a bad review on the 589. The xtr has a lot of bad reviews for weak side walls, one guy said he had multiple plugs in each tire. But I was wondering how wide these wheels will make my machine? Do the wheels have different offsets or are both these wheels the same? If you have either one of these wheels can you post pics here for me? Thank you.
