Theory
135edo is consistent to the 7-odd-limit, but there is a large relative delta for the 5th and 13th harmonics.
Using the 135f val ⟨135 214 313 379 467 499], which tends flat, 135et tempers out 32805/32768 (schisma) and [-11 -15 15⟩ (quintriyo comma) in the 5-limit; 225/224, 3125/3087, and 28824005/28697814 in the 7-limit, 385/384, 540/539, 2200/2187, 12005/11979 and the quartisma in the 11-limit; 169/168 and 364/363 in the 13-limit.
Using the 135c val ⟨135 214 314 379 467 500], which tends sharp, it tempers out 1594323/1562500 and 50331648/48828125 in the 5-limit; 126/125, 10976/10935, and 589824/588245 in the 7-limit; 176/175, 441/440, 14641/14580 and 16384/16335 in the 11-limit; 196/195, 351/350, 352/351, 676/675, and 6656/6655 in the 13-limit.
As every other step of the full 13-limit monster – 270et, 135et probably makes more sense as a 2.3.7.11 subgroup temperament, where it tempers out the garischisma and the symbiotic comma.
