well i searched and search and when you guys talk about tire sizes theres 3 numbers for example 21x8x10 or something, what do they mean and how do i know what size rim i have? I would love to add clearance in the back so bigger tires in the rear is a must. its mainly for trails( mud, rocks, big stumps mainly for like explorering) i'd love to get a tire that can do everything i will hardly or never see sand and snow. would be good to recommend a tire that would be good and good on the budget. So opinoins are welcomed thanks guys can't wait. Also i have wheel spacers and one of them have broken off. So theres no lug nut holding the rim only from 3 of them, is that the stud from the spacer or the main stud from the hub? is it possible just to buy new ones and replace one?? thanks guys i have a 1998 blaster..
