They suck on road. I got a set for free and got rid of them. If you get 20k out of them you will be doing good. The middle will be bald and the sides look like new. The tire psi is not the falt its the shape of the tire. Just spend the $$$ and get some good tires. P.S. M&M tire in Waco Tx sells them for $50 each like new. Get the 37" and you will be OK. They last a lot longer and handle good, $125 each for like new.

 

I don't think the 37's will fit on my truck without a pretty serious lift...my 35's rub the inner fender when at full lock, but thats with a stock suspension, and I'd like to keep it that way, except for a couple spacers for the front.

 

Agree 100% one friend has the 37" on a gas F350 and they arent as agressive looking as a set of 36"but the last a lot lot longer. I ran a set of 36 for one evening before I got a new trackbar and could hardly keep it in the road.

 

Here is a link from Michelin that gives a good, very basic comparison of radial vs bias ply tires. Give it a quick look and see if you think they will work for you. As was already mentioned, short tread life, heat build up. Heck, if the price is right, go with them if you want. You'll never know how they work for YOU until you try them. With your driving style and tire needs, they might be perfect.
