We have 7.0 15 Lt on a camper and were wondering if a 225 75 15 is equivalent size or is there one that is equivalent to the old tire

There is not an equivalent trailer tire to your light truck tires that are 7.00-15, which have an overall diameter of 29.4" and width of 7.8". A 225/75-15 tire such as the Karrier # AM10256 is similar, with a 28.4" diameter and 8.9" width.

You will want to use trailer tires, which will be designated "ST" on your trailer because they have a stiffer sidewall and are designed to handle the loads that a trailer will put on them. Just remember to keep the tires inflated to the max psi in order to get the best performance out of them.

A 7.00-15 trailer tire is still a relatively common size, but we do not carry them. The next closest size is going to be an ST205/75-15 such as #AM10245 rated for 2,150 pounds at 65 psi. Both sizes fit the same size wheels.

Good news, I can help you find a tire for your Sundown Horse Trailer. The 205/90-15 is a close tire size to the 7.00-15. The closest size to a 7.00x15 tire that we offer would be a 225/75-15. One 225/75-15 tire that could work for you is the Kenda…

Answer 6

The two tire sizes you mentioned fit the same diameter and width trailer wheel so unless something really unusual is going on with your wheels the new tires should fit. Is it just that the bead of the new tire is not seated on the wheel yet?

Hey Paul! The #AM20504 you looked at with the +0.5" offset is the only truly solid black wheel we have in this size. The closest thing with 0 offset is the Dexstar Conventional Steel Wheel #AM20514 but it has four small cutouts around the edges…

In this situation I would actually recommend just replacing the wheel studs themselves. The studs on your current hubs should be able to be knocked out, working at the front side of the hub. That way, you would be able to compare your current studs…

Answer 11

It comes down to how much weight the trailer will be at when it's loaded and ready to tow and how much capacity the tires have. If you can determine the max your trailer will weigh and then add up the capacity of all of your trailer tires…
