I recently put the General Grabbers on the S-10, I like them a lot so far. Not as much traction as the Goodyears (which have more traction than swampers), except in gravel, in gravel they are better. However they aren't bad anywhere and they're supposed to wear really well for street use.
The bonus is that 35x12.5R15 tires are only $200 each at Discount.
I was having trouble with the Goodyear tires falling apart due to the desert bashing I was doing. I put big cuts (1"+) through 3 of the treads within a month, all while Goodyear had them on backorder so I couldn't replace them. Luckily Discount let me cert out the 3 bad Goodyears for the Generals so I only had to buy the one.
Personally, I wouldn't trust a 5 year old swamper unless you've been storing them indoors when they aren't on your rig.
