new grizz – 2 questions

I just ordered a new ’16 Grizz EPS to upgrade from an ’04 bruin that has been extremely reliable. (Double engine size, EPS and independent rear suspension – going to be a huge change from the bruin!)

Hopefully the new ride will be in around 2/1. So I am thinking about how to set up and have 2 quick questions:

I just ordered a complete set of ricochet skids. When I installed on my Bruin, I was advised to run a bead of silicone under the frame where the skids will touch to prevent rattling. Is this still recommended? it worked for my bruin – just don’t want to trap water anywhere.

what is the actual height of the stock tires on the ’16 grizz?
I am looking a PB growlers and can’t decide on 25" or 26" in their 6 ply version. Weight is a factor as the 25" will weigh 110 lbs for all 4 and the 26" will weigh 132 lbs for all 4 (this is tires only). I want to install new tires without having to do clutch work.

Thanks!
