Thanks, John. We've talked about 3K and 4K trucks, but for some reason the boss has been reluctant to buy them.

The floor is smooth concrete and the seams are all relatively close together and even. The building was built in stages, with the oldest part on 10 years old or so.

We did talk to our Yale rep, and I've been waiting to hear back from him, I just thought that maybe someone would have some insight on tire widths. We have several trucks of the same make, but they have different width tires. I'm not sure why, just curious how much of a difference it makes. I think Yale told our purchasing guy that the wider one will dissipate heat a little better, and for $30 more, it's worth a shot.

Yale has done almost all of our tire changes, and the 6" tires we have are all flush with the outside of the rim, so any overhang is on the inside. I haven't seen any signs of wear from them rubbing on the frame. Something to keep an eye out for, though.

Thanks again for the reply.
