If you want more size options, you could try the metric sizes. My 33s (Toyo MT) are not the standard 33x12.50 rather, they measure closer to 33.5x12" they also make a 33.5x11.5 but were out of stock. Dunno what the options are for 34 or 35s but if you feel that you may be pushing it going to a full 12.5" width, see if they can come close to 11-11.5" in the metric sizes.
