I have a prairie with 26 in mudlites that have been on there for about 2 years, my back tiers have about 85% tread left. One of my back tiers is cut up and i cant get the tier to seal. I tryed tubs and everything. So I was wondering if it would hurt to run a new tier beside one with only 85% tread? will the differance be enough to hurt?

 

i wouldent do it.
if you can afford it get two then you wont have to buy another tire when the other one wares out.
plus this way if you screw up another tire youll have a spare.
