Tire recommendation for 85 CJ 7

I purchased my Jeep a few weeks ago and I am going to need to purchase some tires. The tires that are on it are Interco Thornbird 33"x10.50-15 these I guess are suppose to be a good mud tire but I am looking for a tire with a combination of street occasional off road trails and beach any suggestions of a decent tire. I am also wondering if I have limited choices with the size rims that I have.

33X10.5 or 33X12.5 BFG AT The 12.5s if you have 8" rims Just lower the preasure down low when on the sand and the extra width will help also.

Thornbirds are a good street and probably a good beach tire but a good mud tire it isn't.

I have 31x10.5 BFG AT's on wagon wheels. These have been great in all situations except our deep red mud.

I like tall skinny tires because I don't like to spin and then sink as well as mine is a daily driver. I used to have BFG 33x9.5 muds and recently changed to BFG 33x9.5" AT's.

I feel sorry for you with those stuckbirds.... man I saw those 'inaction' once at the local mud pits on the grassy edge of the area. The poor driver had to get his three friends out to push it across the wet grass while a bunch of kids in a Chevette with street tires on it 'literally' drove around him in circles laughing to piss themselves. They shouldn't be allowed to sell such trash.

I second the opinions on the the bird tires;
Recommendation;
Determine your gear ratio (few things kill performance as quickly as tires that are too large).
Match the tire size to your gearing 33s -410s to 4.56. Higher gearing (lower ratio numbers like 3.31) will match to smaller tires.
Match the tread too the terrain; Street mostly/only; all terrain, Off road; mud tires.
Pick a width; this is very subjective, I prefer a medium width tire in the 12.50 section width range (about 9 3/4" of tread width) most of the time. For higher traction demands, off road, I go for a 14" bogger (but it is easier to break parts).
Finally pick a brand (BFGs have given me consistently very good performance and life). Interco tires, at least their boggers and super swampers, are generally known as soft compound off road tires that do not last well on the street.

Enjoy!

...a well prepped, well driven, vehicle should do well in any terrain, including the highway.

Carburetors became obsolete during the last century... do what ever it takes to get fuel injection...It makes bigger grins off road.

Although my CJ hasn't left the garage very much yet, I've got new 35" Pro Comp Xtreme M/T's. My buddy runs the 33" version on his TJ. He traveled to California and back last summer and has nothing but praise for them. Said the wear on them is excellent and they grip like none other on the trails and in the mud. They are quieter than Swampers on the highway, have a very aggressive tread for M/T's, lots of side biters, and are radials. Plus they are damn sexy with all the X's on the sidewalls. He's running 4.88 gears right now with the stock 5 speed and runs about 2k doing 55. I run 4.11's, no overdrive and fair about the same.

I like my 32-11-50 BFG MT's. They're a little noisy on the highway but hey, it's a CJ-5. They ride good, have good road manners and have great offroad traction as well as floatation in beach sand.
