Thanks for the compliment, Chris.

I got the Sigma from NTB outside St. Louis. It is a private label distributed by TBC Corp. right here in Memphis but I do not know who makes it.

The Douglas is a Wal-Mart private-label tire mounted and installed by the dept. manager after the shop had closed on a Sun. Maybe not the best tire but THAT is service. I believe it is made by Kelley-Springfield, a division of Goodyear.

I have searched the Internet but cannot find LT-rated tires in my size, 255-70-15 so I would have to go back to the OEM 235-75-15. I bought the rims years ago and could not find a 16" w/ the Chevy 5-lug pattern. Plenty in 6-lug but not 5. These are 8" - will the 235s be OK?

You guys don't want to hear about my REAL towing nightmares. Suffice it to say I had a wheel come off the Tahoe at 75 pulling the trailer between St. Louis and Memphis. Twice!
