Random Dually Tire Questions

1) Family budget is tight right now. The dually is a dedicated TV, not a DD. I have 2 tires that really need replaced and four that are at about 35% tread life. Thinking of replacing 2 tires that need it now and 2 a few months later, then the final 2 about 2 months later. (3 sets of 2 tires) Any reason NOT to spread the tire purchase out? At my rate of driving there may be a 5,000 mile discrepancy between set 1 and set 3.

2) Assuming its OK to buy the tires in 3 sets of 2.... should I always put the new tires on the steer axle?

3) Since I will be buying tires in 3 sets of 2 for the second set of two, should I put the good tires on the inside dually or on the outside?

4) I will probably be buying Firestone Transforce or Cooper tires...However, I am open to other brands, anyone have experience with Kumo, Hankook, or other brand tires on a dually? I have heard that the two best dually tires are Firestone Transforce and Michelin's. I really want GOOD tires.

5) I run Simulators on my factory steel wheels. I can check my front tire pressure without removing the simulators, and the outer Dually, but the inner dually is impossible. Can I run "valve extenders" successfully for the inner dually tire?

6) Should I have steel valve stems installed? Currently there is regular old rubber stems. Seem to be ok too.

Thanks!

    Just match them by corner. Yes, I would to front first, then when you do the back, do one side, then the other. Of you mismatch diameters on the same corner, the tall one will wear faster, and if you're towing could get too hot.

    Valve extenders work just fine as long as you have steel valve stems. Tire stores around here usually mandate steel stems on duallies (proabbly since most end up with extensions).

    Best tires I have ever had at Toyo M55 tires. They are a commercial traction tire developed for the NW logging industry. Super good traction and mud, snow, and standing water. Dry traction is nearly as good as the Open Country A/Ts I used to run, and the ride is better. They have stood up well to very primitive rocky-road driving, sometimes at speed. And even towing at capacity at high speeds (80+) through the dessert when its over 110F degrees, the tires never get too hot (unlike the trailer tires).

    Main downside is cost. Also, you can hear them hum when the windows are down, they have low speed rating (89 MPH), and they are a heavy tire so it takes a little extra work and weight to balance them. I get about 50,000 out of my rears, and about 80k on the fronts. That is nearly double what I could get out of the Open Country tires.

    When I bought a new pair of tires for my dually motorhome, I put them both on the same side, so the outside diameters are equal.

    I would start with the front pair, then move to each side as you have the funds.

    However with 4 wheel drive, all the tires need to be the same outside diameter if in 4 wheel drive, so replace all at once.
