Wheels & Tires On The Cheap?

[l008com]

I have a trailer I hook up to my kart. Its the kind of trailer lots of people hook up to their riding lawn mower. It runs on a pair of wheelbarrow wheels. I keep destroying the wheels (I have been known to stick some seriously heavy boulders in the trailer :-) ) So I was at lowes and I found some nice 15 x 6 wheels and tires. I think they are meant to be the front wheels to said riding mowers, but they would be perfect for this trailer. Much larger volume tire, and twice as wide. Lowes wanted $35 a piece though... I think not. Anyone know of any super bargain spot to pick up wheels & tires like that?

We have some in stock with 3/4" shaft somewhere on our website. I bought a set for my yart trailer as well. I think I had less than 30 bucks in both,. I get employee discount too!
