Den, you're a lucky man. !0,000 miles on 4 year old BFG's? Are you talking front or rear? I might get about that on the front, but my rears usually last less than 4 years and lucky to get 4,000 miles to a set of T/A's . Don't use them for the track or pull hole shots. Just normal use. Dunlop GT Qualifiers were even worse, might have to try Michelin next.

I was returning to Pa. from "SHADES" 3 years ago, Left front blew out at 70 mph. No warning just a loud bang, just like NASCAR. Was a ply separation.Tyres were BFG 4 years old with only 10,000 miles. I worked for Firestone for 15years. Please do not run any tires on your street rod that are older than 4 years.The rubber breaks down, even when your rod is not being driven. Heat builds up inside the tire and the plys start to shift, the older the rubber, more of a chance that the plys will seperate. You may have warning or you may not. Cost me $2500 to rpair front fender on 41 chevy cpe. No spare of course. Got loaded on roll back. Car is very low even with all tires up and rolling. Additional damage to pan below grill and bottom of fenders. Not fun. But please for the sake of your and your familys safety do not run tires the are older than 4 years. If you think about it they are cheap, compared to injury or damage to your car. First thing I did after I arrived home(bought tire at towing garage to get home) I purchased 4 Michelins. Also check your pressure often and feel around the back of the tire checking for bubbles or bumps. This is the start of trouble. Coker radial wide whites are noted for this also soft spots and cupping in the tread area caused by bad rubber, not cured properly. During production of Firestone tires during the early ninetys I production scheduled trear tubing machines. There were age limits on radial tread rubber, had to be minimun of 12 hours old before using. And all treads were scrapped when older than 7 days. Due to the rubber drying out. This is before construction of the tire. Please don;t drive on old tires not matter what brand. Hope this is of help.

Lost a right rear tire on my 38 at 80 mph coming back from Louiseville in 2004. Quite interesting in the mountains. Tire came apart diagonally. 30 second vibration warning.

I had checked all of the tires before I left, no visible defects.

By the way, it was a BFG.

Al., when I replace the Dunlaps with BFG, I went to the BFG website to check out their tires. On their site they have charts with details of all the sizes available in each tire series including the tire width, height, recommended rim sizes, tread depth, etc. I found the the height, width and rim size of my existing tires and then looked to see what else I could get in similar sizes. If the tires you have now, fill your openings, you wouldn't want too much bigger. Smaller would look funny. You also have to pay attention to rim width, cause you wouldn't want to exceed the recommended safe size.

Kind of surprising to hear you have 205r75x15's on the rear, as that is the size I have on my front. My rears are 255r60x15's, previously 275 r 60's, but I dropped them down when I got new rims (8"width versus the old ones of 8.5"). I found the BFG size charts to be very helpful and found that their sizes for various tires were virtually the same for the same size tires from other manufacturers. Made the choice for replacement tires much easier.

BTW, we used to have the Uniroyal Tigerpaws on some of our fleet cars. We got better than 100k on those tires before replacement, and the Tigerpaws still had at least 20% of their tread left.
