Trouble seating tires on my rental beach cruisers.

I have tried everything to get the tires to seat on the rims of my new Taxi beach cruisers, oil, high pressure, oil and high pressure, grease and high pressure. They still have low spots that makes riding uncomfortable. Any tricks or reasons why this happens? Thanks.

Probably an insurmountable tolerance issue. There is a tool made by Bicycle research, specifically for pulling up poorly seated tires.

I suspect part of the problem is that the advent of hook sided rims has led to some loss of the standards involved. Straight side tires seated on the shoulders of Endrich pattern tims (like car and motorcycle tires). Tires made for hook edge rims seat based on the bead tucking under the hook, and so less effort is made to maintaining the size of the old seating location inside (radially) of the bead wire.

If you can't get these babies to seat properly, try other tires.

BTW- inflating to riding pressure and waiting a week so so, might relax the tire enough for a successful go at reseating.

Perversely, cheaper tires, ie. the generic stuff sold as basic repair tires at bike shops and the big boxes may serve you better.

How so? I very rarely had seating problems with good tires, cheap ones were stubborn sometimes...

My point is that there seems to be little consistent correlation between tire brand or quality and fit. It's become a guessing game. However most better tires these days are made for hook edge rims, but many of the less expensive tires are still using older molds dating to the straight side rim era.

You can ask others using the same size if they have more or less luck with particular tires, or you can do some trial and error.

BTW- If you're not far from NY I still have a decent stock of IRCs that seem to be easier fits, but they're probably not worth shipping too far.

"...oil, high pressure, oil and high pressure, grease and high pressure."

I'd keep oil and grease away from your tires (or any other rubber parts) and rims; petroleum products can harm rubber and won't do rim brakes any good either.
