The Slate truck's stock tire size is 245/65R17 on 17 x 7-inch steel wheels, 29.5 inches in overall diameter, per Slate's official spec sheet. Slate has not published the bolt pattern, offset, center bore, or load rating — no verified figure for any of them exists, and the 5x120 number circulating on forums is a photo estimate, not a spec.

What is the Slate truck bolt pattern?
Slate has not published it. Not the bolt pattern, not the offset, not the center bore, not the load rating. We checked the spec sheet PDF and the live configurator again on August 10, 2026 and the figures are still absent.
That is an unsatisfying answer to a question people are actively searching, so here is why we're giving it anyway. There are two separate contamination sources feeding wrong numbers into search results for this exact query:
- Forum photo analysis. Threads circulate 5x120, 17x8, ET25, derived from studying pictures of demo trucks. The 17x8 width in that same estimate contradicts Slate's published 17x7. An estimate that gets a published number wrong is not a source for an unpublished one.
- A name collision. An aftermarket wheel brand sells a wheel model literally named "Slate," offered in 17x8 +25 and 20x9 +20 with a 6x139.7 pattern. Those specs describe a wheel product, not the Slate truck, and they surface constantly in searches for Slate fitment. 6x139.7 has nothing to do with this vehicle.
Practical consequence: no third-party wheel can currently be confirmed to fit a Slate truck. If you want a different wheel at delivery, Slate's own accessory sets are the only confirmed-fitment option. This page gets the real numbers the day Slate publishes them.

Why the stock size is a good one
245/65R17 on a 29.5-inch overall diameter is a sensible truck fitment: a tall sidewall on a modest wheel. That's the setup that absorbs potholes, rides quietly, and costs least to replace. The 17-inch accessory set doesn't change the diameter — it changes steel to alloy — so the ride characteristics stay put. Going to 20s is where the sidewall shrinks and the ride firms up.
