Tire/rim question

[mrkastni]

I am looking to upgrade/replace my tires and wheels on my old Spartan tilt-roller trailer. The current tire size says 5.3-12 and the rims are 4 hole 4" spacing. I have only been able to find 4.8-12 tires on this rim. Any ideas on what to do or where to find the proper size combination? I would like to upgrade to the whitespoke, but that is just an asthetic upgrade for this old rig. No new boat this year for me, have to make small adjustments as I can. I keep my boat indoors, but I am not sure just how old the tires are. They look fine, but I have heard that they should be replaced every so often for safety reasons. Any input on any of this is appreciated. I am in NW Iowa if anyone can give location within a couple hours, that would be fine, or I can order in.

Thanks,

Mike

Try Fleet Farm in Mason City. At other locations, Fleet carries a complete line of tires, rims and mounted combinations.

Try Nothern Tool, they have all kinds of tires and rims like that, I went to the Tires Plus by my house and they ordered me tires for my boat from a company thats uses them on gulf carts. my 2 cents
