I have a 2000 Xplorer XLW with rear dual wheels. We recently purchased the van, and it has Toyo Open Country AT tires. I was looking at the owners manual under tire pressure, and it says the outside dual should be at 45 psi, and the inside should be at 55 psi. I've never heard of having different tire pressures for duals, but then I've never owned a vehicle with duals before. So should I be following these recommendations? Currently all six of my tires are at 60 psi.

I keep all 6 of mine at 60psi also. Never heard of the unequal pressures and I have been driving a dually for a long time.

Here is a good question to ask someone who has been driving a dually for a long time. Have you ever had a flat on the outside dual? I never have.

Never heard of it either, doesn't seem to make much sense. Duels on the truck are all the same, duals on the fiver all 8 are the same.

That has to be one of the dumbest things I have read in a really long time. Inflate the duals to exactly the same pressure. IMHO I would inflate them to max as listed on the tires sidewall. That way you are guaranteed of carrying the maximum load without overloading the tires.

According to the Toyo web site the maximum pressure for my tires is 80 psi. Really don't think I want to inflate my tires to 80 psi, although I suppose I might get better mileage, and a firmer ride, by doing so.

Bear in mind that these are '3rd party' duals, so wisdom from OEM duallie owners doesn't necessarily apply. I believe Xplorer used an adapter kit to add the outers to a SRW axle, and added extensions to the fenders.
This was done (for sure) to increase the load carrying capacity of the SRW tires, and (I think) to increase stability. My own attitude is that if it's in the RV maker's manual, I'd at least _try_ it. Maybe up the suggested pressures by 5 or 10 PSI. Just take note of any odd handling or tire wear.
Also, Xplorer has been thru at least one change of owners, maybe two, since your van was made, but they _may_ be able to provide some info on this. Google to find the current company's email & phone.

I have been driving dualys for 7 years. I also spent some time driving an 18 wheeler. I've never heard anything other than keep the duals at the EXACT same pressure.
I disagree with inflating to the max pressure on the side wall. Look up the load inflation tables for your tires. You should be able to find it on the tire manufacturer's website or have a local tire dealer help you. You will also need to weigh your RV fully loaded for a trip. Then just compare your loaded axle weight to the table and you will know exactly how much air to put in the tires.

Thanks everyone for your suggestions about tire pressure. Yes my dualies are aftermarket. I'm thinking I might check the web site of the company that makes them just to see what they say. For now I'm not going to stress over this, and will leave the pressure at 60 psi on all six tires. Am loading the van up now for an overnight shakedown cruise. I'll try and get by a weigh station just to see what it weighs.

We have the same Xplorer. When we first purchased it in 2002 it had Michelin tires. My husband says that (he can't remember exactly who or what--thinks it was from Xplorer) that Xplorer changed the recommendation from 55 psi to 70 psi. When we first purchased the van we called Xplorer many times.
We now have different tires, of course, and they are Michelin ribbed tires.
We have always kept all six of our tires at 70 psi. Have owned the Xplorer for almost ten years.
