I took the truck to firestone today to look at their Destination ATs - wasn't impressed! They are definitely a step down from the Revos in both looks & functionality.
The good news is that they did a tread depth on the old tires, and found they still had 55% good wear left - not bad for 40,000 miles! The guy commented that there was some minor chunking (due to various off-road trips) but the tire still looked good - and he REALLY wanted to sell me a new set. But after seeing the depth remaining he realized it would be a while. Ye haw! I'm certainly in no hurry to spend tire money, and at this rate they likely will go another year before I start getting serious about replacement. Besides, that's what is supposed to be a real selling point of the high tech Revo - it keeps it's grip & integrity far into the tread wear.
I then went to Costco to do some grocery shopping, and in the mean time have the Revos (which I had a new appreciation for) rotated. Unfortunely Costco doesn't sell Bridgestone any more (wonder if the Firestone dealers complained?), but they said they can order a set of BFGs for about $155 each. They run a special of $15 off per tire a few times a year, so . . .
I figure my top choices now are the BFG, or perhaps even another set of Revos. If this set gets the kind of mileage I think it might (60k+), and maintain their integrity, then that's pretty hard to argue with - even if they are nearly $200 tires! And Firestone often runs $25 off per tire.
So in the final analysis it looks like this:
$170 tire (Revo after $25 off)/60,000 miles = $.0028 per mile
$140 tire (BFG after $15 off)/50,000 miles = $.0028 per mile
UPDATE: Well big dog turd - now I can't find the BFG AT KO in the stock size - only the BFG TA Rugged Trail! The Rugged Trail is much more poorly rated than the KO - double dog turd!
UPDATE2: Looks like the Revo & Yoko Geolander AT-S are my only "decent" choices for stock size.
