Hey guys, so I just picked up my new 16 rzr xp1k 2 seater, which is also my first ever side x side. I have a few friends that have them and I am no stranger to offroad as I race with a 6100 truck team with my good friends. Just a few questions I have regarding preventing future headaches seeing that this thing is new.

1.I know the belts fail, and I will be picking up a spare today, which is the best belt I should buy and what holds up the longest? also how many should I keep in my rzr as spares?

2.whats the largest "safe" tire I can run on either a 14 or 15" wheel? by safe I mean not overly straining the trans and motor. I’m not new to gearing and I know what happens when you throw large tires on something that has inadequate gearing, first hand experience.. also which is a better choice? 14vs15" wheel or is it just aesthetics?

3. finally whats the biggest thing to look out for right off the bat on my rzr? I spent all last night looking through threads on clutches and trans issues and all that fun stuff. I saw how some rzrs from the factory dont have the bolts completely tightened as well as other issues, so if theres something I should check now before I really start using it, let me know!

thanks guys!
