Tires

Going to standard truck sizes will be far easier in terms of prices and availability. That includes rims. I'd only put larger size if the weight demands it. I'm running 12r22.5 and even those not so standard. I think 11r22.2 is the standard truck size.

Your  fuel milage,top speed will take a hit and they need more air pressure  only thing smaller tires have going is more power on take off and price

Just to let everyone know, I went ahead with four Firestone FS860 tires for the drive axle. They are the full 315 80R 22.5. Thanks for all the discussion on this!

Maybe I should start a new thread, but what tire speed rating do you guys run? In looking at tires, I have come across this. When I bought my tag tires, I bought a speed rating of K, which is only 68 mph. At the time, I didn't know what a speed rating was. Now that I ordered drive axle tires, I'll have to find out what the speed rating is. I believe they are L, or 75 mph. I've heard that the lower speed rating is ok since I am so far under weight. Any thoughts on this?
