you should not mix the 2 on the same axle,IMO

I run 29x15.5x15 on a 12" rim with 165/15 on a 3 1/2"x15 rim on a 85 step side truck with no probs

I also run some 235/15 on 7" rims on the front with no probs

M/T has a wide sreet radial tire also thats new

you could run some front runners from micky to matcha sportsman

IMO,they dont wear that good for street driving.for the front

my sportsmans are holding up good to daily driving and has been 1 1/2yrs now,reg street tire on the front

run em!
