Yep this is why I run 12" rims on my quad. Learned this lesson on my truck. Was running a 20" rim with 35's but there is not enough sidewall for good impact protection. Went back down to an 18" rim with 35's and has never happened again. I really do like the look of a 14" rim (or larger) but unless you are running a big lift (4"+) or have a side-by-side 12" is the way to go in my book. Just my 2 cents
