A customer's Subaru Uncharted needs tires and the ticket just says "Dunlop SP Sport Maxx 060" — is that enough to order?

No. The Uncharted's US fitment uses two Dunlop models across two sizes: the SP Sport Maxx 060 in 235/60R18 103H and the e.Sport Maxx in 235/50R20 104V. Confirm the size off the door-jamb placard and the sidewall for each axle group before you pull stock, or you'll get one position right and the other wrong.

Is Nano Black the technology that handles the EV's weight and torque?

No. Nano Black is a cosmetic blackening process for the brand logo and sidewall engraving — it deepens the black and improves lettering contrast, with no load or torque function. The features doing structural work are the asymmetric tread pattern and the high-stiffness shoulder blocks, plus the silica compound. Don't sell the paint as load capacity.

The spec lists 103H and 104V — are those the speed ratings I should match?

Those are two separate things. The number is the load index (103 and 104, the weight each tire can carry) and the letter is the speed symbol (H and V). On a heavy battery SUV, the load index is the one you cannot undersize. Match both the load index and the speed symbol to the OE figure for the correct axle group.

Can I put a cheaper tire on an Uncharted to hit a price?

Yes, within limits. An economy tire in the correct size with a load index and speed symbol that meet or exceed OE is a legitimate choice for an older vehicle doing low-stress miles. What you can't cut is the load index or the speed symbol — on a heavy EV, an under-rated tire is the comeback you'll see again in a few thousand miles.

Are there known weak spots on this tire I should mention to the customer?

Two are worth flagging. Owner reviews are mixed on warm-wet grip — some report it feeling vague on occasional wet summer roads despite a strong wet-grip label — and at least one owner reported repeated sidewall-bubble failures. Neither is a recall, but on a heavy EV I'd inspect for impact damage at every rotation and recommend road-hazard coverage.

On paper this is a routine trade headline: a tiremaker landed an OE contract, the kind of announcement that scrolls past a parts desk without a second look. Read it that way and you'll bill the wrong tire. The catch sits one layer down. The Uncharted's US fitment isn't one part number, it's two. The SP Sport Maxx 060 goes on in 235/60R18 103H, and the e.Sport Maxx variant goes on in 235/50R20 104V. Different model, different size, different rim, different load index, different corner of the car. Pull only the headline name and a 20-inch hoop comes off the truck for an 18-inch axle.
