I have some 31" skinny ols i wana trade 2 skinny for 2 wides if anyone knows or has some around the houston area let me know thanks

Ok guys needing advise on some tires. Here are my options I'm concidering 29.5 outlaw og1 , 29.5 outlaw 2 or 30 in silverback. I like the look of outlaw2 but I'm not big on the weight of them. The backs and outlaw 1 are real close on weight but I've heard they ride a lot worse then the outlaw2...

I really want to put on 29.5" Outlaw 2's but I'm sure they won't fit without some modifications. What has to be done to make these tires fit?
