Time to replace the 4 tires on out fiver as they ar 6 years old... We have the Goodyear Marathon G614 tires LT235/85R16 "G" and have had no problems with them... The place I go for tires is main...
We have been running G614's for the past 4 years without a problem. I would suggest staying with them. They are pricey but the peace of mind is priceless.
