I have a 78 f250 with 36+14 groundhog tires that i bought in the mid 90's time for new ones does anyone know if they still make groundhog tires if so where can i get them.I had the radial tires the ride was so smooth you could set a beer can on the dash and it would not spill. thanks for any help

 

Doesn't appear that they make them anymore, but I found this link: Off-Road Tires - Quadratec
Pro Comp, Dick Cepek, Mickey THompson names have been around for awhile but can't vouch as to the quality. Not sure where your located but most reputable tire shops can get something similar to what your looking for. Its not a Groundhawg but the BFG Mud Terrain is a awesome tire in the mud from what I hear. Did you look at Interco's website?? Home | Interco Tire

 

Denman in youngstown ohio shut down back in either 2010 or 2011 so the tires haven't been made for years. The next closest tire in terms of looks would be the mickey thompson baja claw or super swamper bogger.

 

TSL Swampers are excellent... Very comparable to the Ground Hawgs.

 

Oh... And the local guys rave about Pitbull tires.

 

Growing up in the 80's and 90's every truck you saw in a magazine ran the Ground Hawgs. I loved the look of those tires. Great tires in the mud--going forward, do not expect to back through mud with them on.

 

I just today put on a set of Pit Bull Rockers 37X12.5R15

 

That is a good looking tire..

 

Nice lookin tires there!

 

I now have 3 sets of the IROK ND's, 2 of 285/75/16 and 1 of 305/75/16, I too loved the Ground Hawgs, wish they still made them! However, I have been THOROUGHLY impressed with the IROK ND's! They only go up to 35's tho,,,
I bought 1st set on a whim, price was great, going on my hunting/woodcutting truck, so I wanted an aggressive tread, went up hunting, middle December, lots of snow and melted snow and mud and clay-ey muck,,, they did better than any than any tire I have had up here in the mtns.! So, I bought 2 more sets for my other trucks!
Depending on what you want to spend, a friend of mine has the original IROK's, and he said he probably wont buy anything else for the mix of everything up here.
