limestone flat tires please help

[dave1949]

Our Ford Explorer/Sport Trac has Goodyear Fortera tires. Four ply tread, two ply sidewall. That was the original equipment from the factory and although they are expensive and not a high mileage tire, I have stuck with them for replacements. I like them for their road grip. I think they grip (and wear) because they are a fairly soft tire.

Stone through a tire should be a once in a blue moon thing I think--granite or limestone. I can't guess what is going on there, and I've had both granite and limestone drives.

Have a course of dense grade aggregate laid over the existing gravel, it is dust and fine crushed stone. I have all my gravel roads done this way and never have suffered a flat tire from them. Until you have several layers of this some of the larger stones make work up through it, but you can remove them. If you have a good base and drainage this cover should last for a number of years.

I have used limestone 304 in driveways for decades, and have not ever had any problems.

This seems very strange.

Putting more stone on top is not a good answer. Sooner or later, the stuff you are covering up, is gong to make it back to the top.

It would no doubt help if you could compact it first. That would flatten out the stone, and generally orients it so you have a smooth surface. Don't see how you could do that though, if it is frozen.

Thanks for all of the advice I guess I'm glad you all find this as odd as I do..

I had many people echo the trouble free use of 304 on driveways and it looks just like the picture referenced on page 1, so I'm thinking somehow this load of stone has sharper than average pieces in it. This is obviously going to be a problem because there was 40 ton of it put down and compacted. The ground is thawed today for one of the first times since this mess started so I had to decide on something fairly quickly because I've got Christmas company coming in tomorrow. I had him topcoat it all with 57. If the problem continues he suggested a whole lot of fines or some asphalt grindings. I'm dealing with a fairly steep grade so all the fines would eventually be washed to the bottom of the hill though.

I heard some local people blaming the oil and gas rush in this area for poor quality of stone in the area. Not sure how much weight that holds.
