Or close as I can find. I make several trips to my local landfill yearly & the trails there are horrible. Metal debris, broken bricks everywhere, boards with nails in them & sharp rocks. You go 3 mph or it will bounce you off the seat. So far no flat tires, just a slow leak one time. It's time for new tires so my question is; are truck tires more durable than car tires? Is there a difference in construction or is it just a different tread pattern? I do about 5K miles a year & usually not highway so ride & handling don't matter as much as durability. Any recommendations? Size is 225/70-15.

 

You can get "run flat tires" but you have to replace the whole tire once you actually use the "run flat" feature because sidewalls do break down, so not for your application

There are tires made with Kevlar making them less susceptible to punctures

You can carry tire sealant, it will seal a puncture and inflate the tire a bit, but it does need to be cleaned out within a few days
So helps you if you know tire is going flat and don't want to get out the spare, or don't have a spare to use
Problem with sealant is that it will pool at the bottom of tire in a clump when vehicle sits, and won't liquefy again until tire heats up, so out of balance tire for a bit if you just leave it in, can also damage rims if left in for long periods, eats away at some metals

And then there is MICHELIN® Uptis tires, aka Tweel
No air, lol, so can NEVER go flat, ever
But not for cars or trucks quite yet, they are available for ATVs, only rated for 36MPH
