help with trailer tires and rims

[rundrave]

so I recently scored a nice little deal on a trailer where some guy named craig sells stuff.

anyways got it wired and only thing it is missing is a spare tire.

I want to go buy another rim and tire for it. how close/important is it to measure the bolt pattern. as you can see in the pics its has 5 bolt rims so I looked it up and on odd number bolt wheels measure any bolt hole center to the point halfway between bolt holes on the circumference (opposite side)

like this pic below:

I believe mine is 5 bolt holes with 4.5” would mean 5 on 4.5". Can I just go to a salvage yard or something and just ask for a rim with a 5 on 4.5" bolt pattern?

Also here is the condition of tires, plenty of tread but showing some cracks? Would these hold up hauling a 600lb load for 300 miles?

Or should I just purchase some different tires? They are 205/70/R14

As long as the center bore will fit over the hub and stud dia are the same then its down to 5x4.50 bolt pattern on a 14" rim.

I wouldn't trust those tires on a short trip!! You better bring two spares.

rundrave, As Surface Tension stated, watch the center hole. The old ('50's thru '70's) AMC, Chrysler product 'fullsize' wheels were 5 on 4.5 in 14" or 15" diameter with about the largest center hole. Look out for the old Ford wheels though, they also were 5 on 4.5 but center hole is about 1/4" smaller diameter. Try to get one that has '0' offset, it'll be somewhat easier on your wheel bearings. The diagram of the 5 bolt wheel is the way to measure them. It's quite easy to get the measurement as there's a good difference between the SAE wheels and the metrics. Before you mount any tire on the wheel, try it on your trailer just to be sure there are no clearance issues. I'd be 'leery' of those tires on any trip with distance/speed, they look pretty dried out. Phred52

well my search for a rim will be a chore it looks like. I found a couple today but the center hole for the hubs is too small. I am gonna go to a salvage yard tomorrow and try to find one.

I got some new tires and will be replacing those as well. thanks for the help
