I guess I'll keep the same size tire. I thought, because the size of the tire, it cant handle the weight and is the reason it blew up on the highway.
I spoke to the prev owner and they told me that they never had a problem with the tires, they also load the trailer with coolers, camping gears etc and drive for over 8 hours and never had a problem. They replaced the tires last year
I guess I may of had a leak, I never check the psi when I left the camp
Also if the tires should last 5 years, why should I upgrade to a bigger size??
