I was on Treadepot.com and found a great tire for 250 4X4. It is called the Gator. It looks like a Vampire type tire but it is lighter, cheaper and it comes in 23X8X10 and 24X11X10 sizes. If you have been wanting a good replacement here it is.

 

I put super swamper tsl's on the wife's 250 explorer,what a beast it is now!They are 25's rear 24's frt I thought it would have a large power loss but you can hardly tell.
