Went for a ride yesterday on Mt. Magazine in western Arkansas. Currently running stock 24" tires on stock wheels. For most rides I can go where all the big boys go until today. Today my little shetland met its match. So I am now looking for some more clearance. What is the best way? I am not worried about width as much as cost so I would like to keep my factory wheels. I was thinking of getting 27/9/12-27/9/11 tires. How much clearance will that really give me? Will the benefit be worth the cost? If I'm to tippy I can add spacers later.
