Front vs Rear tire size on Stock Northstar

[New Polaris Dude]

Can anyone tell me why the front 30 inch tires are 10 inch and the rears are 11 inch, both on 15 inch rims; Is there a reason?
Also, which spare should I carry, 10 or 11 inch?

I carry the 10". Not sure why factory does this. Will make the the same when I run out of tread on these.

Agreed on the 10 inch, thanks for the response

I couldn't handle the thought of having 1 spare tire to only fit 2 wheels....so I got 5 33"x10"-!5 Terrabites and one new wheel, you can find them on Ebay for about $200 for the wheel, tires were $205 each thru Amazon. Problem solved, just throw more $$ at it.

OK, here's the skinny; I pulled the trigger today on the expedition. The shop told me the reason for the 11 inch rears is from Polaris who assumes that everyone would be packing a lot of gear in the back and it would be heavy, thus the 11 inch tires. He said just run them down and replace all four with 31 inch when they are gone.

33” fits fine! No rubbing on full turn, adds 1.5” of height. I’m an old guy, so I’m not jumping any sand dunes, could take some clearance off of travel, but absolutely nothing noticeable so far.

I have 33” Coyotes and they rub bad. I had to install 2” forward A-Arms and metal wheel well guards.
