Flotation sizes are almost always LT construction, so they share the light-truck band. Speed symbols run low because the aggressive tread patterns these sizes are sold in are rated against heat build-up, not against sustained high speed.
The load-index range shown is the band this CLASS of size is typically produced in — not a list of what is in stock for this exact size today. Load index and speed symbol are printed on the sidewall of the specific tire you are holding, and the required minimum is on the placard of the specific vehicle you are fitting. Read both.

Equidistant from four sizes
| Size | Diameter | Against 34x10.50R17 | Section width |
|---|---|---|---|
| 33x10.50R17 | 33.00 in | −1.00 in (2.94%) | 10.50 in |
| 33x12.50R17 | 33.00 in | −1.00 in (2.94%) | 12.50 in |
| 34x10.50R17 | 34.00 in | — | 10.50 in |
| 35x11.50R17 | 35.00 in | +1.00 in (2.94%) | 11.50 in |
| 35x12.50R17 | 35.00 in | +1.00 in (2.94%) | 12.50 in |
Four codes, one inch away in each direction, and the same 2.94% in all four cases because they are all measured against this size. On width, it is the narrowest of the five by a full inch.
The two 33s below it share its exact section width in one case and exceed it by 2.00 in in the other. The two 35s above it are 1.00 in and 2.00 in wider. So moving up or down this ladder is never just a height decision unless the 33x10.50R17 is the destination.
Why the 34 is empty
Off-road tire sizes are named in twos — 31, 33, 35, 37 — and the odd numbers between them are sparsely produced. 34 is the gap in the middle of the busiest part of the range, and this catalogue's coverage reflects that: six 33s, six 35s, four 37s, and one 34.
The metric codes are under no such obligation and fill the space readily. 315/70R17 is 0.36 in above this size at 34.36 in, 305/70R17 is 0.19 in below at 33.81 in, and 275/65R20 lands within 0.07 in on a completely different wheel. All three are wider than this tire by between 0.33 in and 1.90 in.
The narrowest way to stand this tall
10.50 in of section under 8.50 in of sidewall is what makes this size unusual rather than its height. Nothing else in the catalogue reaches 34 in on a casing this slim, and among the metric alternatives only 255/80R17 — 0.94 in shorter, 0.46 in narrower — comes close to the proportion. Why a narrow casing at a given diameter behaves differently is set out in the section width vs tread width reference.
