There is nobody that can tell you what tire you need here. A FED is a different animal than all other cars. Your car and mine to are different than even all others here. Depends on how stiff your chassis is, how much it flexes, weight distribution, power, converter, tire, wheelie bar, weather, track and a bunch of other things. I had to go through 5 different tire combinations to get one to work good and you have to do a bunch of testing with tire pressure and moving weight around before you know if that combination will or will not work. I had to go back and stiffen chassis, add bars, lower rear end in the chassis and raise cage. I had to move a bunch of weight up to the nose. After all that work and money my FED would hook up and go right down the track every time. Still it is difficult in the short, rough shutdown tracks. Some of these FED's are flimsy and flex like crazy, some weigh less than 1300 race ready, some have stiffer chassis, some have full bodies that may stiffen chassis up some. Just my battery alone I started with it in the nose, then moved it to the middle and then moved it to very back of car and now it is back in the nose with additional weight.
Even some cars that look similar are nothing alike when you look at all of the variables. If you want someone to tell you exactly what you need then get you a generic 4 link rear engine dragster with a BBC. They are all basically the same but you can pick your own colors but you still have to paint it with the tribal swirls paint job. (you choose colors though).
If you want to make your FED work you are going to have to take it out, try different tire pressures and move weight around and work with wheelie bar until you get it hooking good with out hitting wheelie bar too hard and no bouncing. Then if it does not work you may have to add tubes and if that does not work you may need to change to a different tire. Even with the weight I added up front I am sure under full throttle at the finish line there is very little weight on the nose. Our cars are a 150 MPH unicycle basically and weight distribution is critical. I think in the end you want front wheels to come up a little, chassis flex some and hit wheelie bar light then keep the chassis flexed under full throttle and enough weight on front tires to steer as you are going down track. Basically I am trying to keep almost all weight on the back tires until I let off the gas with out pulling big wheelies. I could set up my car where it bulls big beautiful wheelies but it would pop out of beams and go red and you could not steer it.
