Correct tire size

I currently have Goodyear Marathons on my 2005 Safari (28'). I am looking to buy Maxxis ST 225/75R/15 E1 BSW. As I understand, it is a 10 ply tire. The Marathons I have now are 8 ply. Can I switch to 10 ply without a problem?
Do I need a certain kind of wheel? How do I find out what kind of wheel I have?

I switched from Marathon 8 ply to Maxxis 10 ply. I increased tire pressure from 65 psi to 80 psi.
The only problem I had was the 5 year old steel wheels were rated for 75 psi. One wheel started to leak halfway across Montana.
I replaced the wheels with aluminum wheels and no problems since.

We had the OEM Marathons on our 2005 Safari 25FB. We switched right over to the Maxxis load range E's without any problem. We ran our Maxxis at 80 psi. Our first set of Maxxis went 24,000 miles before experiencing tread separation. We replaced these with another set of the Maxxis. They did not do as well. They only went about 13,000 miles before the tread separation began.

The OEM cast wheels handled the Maxxis fine. Being that you have a 2005 model year, you probably have those same wheels.

Here is a picture of those wheels.
