A Model Y picked up a screw on the I-15 south run toward Primm at 5:30pm. The driver looked at the spec sheet at delivery. The car didn’t ship with run-flat tires. It didn’t ship with a spare. The tire lost pressure fast on a 130F shoulder. Tesla publishes tire specs per trim. Most Model 3, Model Y, and Model S configurations in 2026 do not include run-flat tires. The Cybertruck is the partial exception with different wheel-and-tire options. The lack of a spare is the design choice. The lack of run-flat is also the design choice. The freeway shoulder is where both design choices meet the desert.
A run-flat tire lets a driver keep going at reduced speed for a limited distance after a puncture. Tesla has not shipped its mass-market trims with run-flat tires as a standard fit. The tire pressure monitoring system (TPMS) is the published early-warning system. The plug kit and the tow are the published repair.
What Tesla publishes about tires and spares
Tesla publishes tire specifications per trim in the owner’s documentation and in the Tesla app. A Model 3 Standard Range, a Model 3 Long Range, a Model Y Long Range, and a Model S Plaid are sold with specific tire brands and sizes. The published spec sheet for most Model 3 and Model Y trims does not list run-flat tires. Tesla also publishes that most trims do not include a spare tire. The Cybertruck ships with a wheel-and-tire setup that supports more service options, including tire repair kits that differ from the Model 3 and Model Y kits.
Confirm your trim’s tire and spare spec in the Tesla app or in the glovebox documentation. Don’t assume one trim’s spec carries to another.
Why a run-flat would help in valley heat
The official NWS Las Vegas climate record (NWS Las Vegas / NOAA, KLAS) puts the average July high at 104.5F. About 78 days a year reach 100F or more. About 9.4 days reach 110F. The east valley and downtown pavement can run up to 11F hotter than the rim. Asphalt in Summerlin or Henderson reaches well above ambient in direct sun.
A run-flat tire at 130F shoulder temperature is still under pressure for a limited run. Tesla publishes that most trims don’t carry one. The published early-warning system is the TPMS. A driver who sees the TPMS light should pull over. A driver who doesn’t is gambling on a slow leak that becomes a fast leak at 130F.
What the lack of run-flat means in practice
A sidewall blowout on a Model 3 on US-95 near Indian Springs is a tow. The published Tesla repair is a tow toward a service destination. The contractor’s tariff applies. The contractor is on Tesla’s network and holds an NTA certificate under NRS 706. The operator’s bill is the number the driver pays.
A slow leak on a Model Y in a Winchester garage ramp is a plug. The Tesla-dispatched contractor plugs it and reinflates. The driver rolls to a tire shop. The plug is not a permanent fix in valley heat. Roll to a tire shop and replace the tire properly.
The published spare plan
Tesla publishes the tire repair kit per trim. The kit includes a tire sealant and a portable compressor. The kit plugs slow leaks in the tread. The kit does not fix sidewalls. The kit does not reinflate a fully deflated tire.
A driver who wants a spare plan should buy a Tesla-compatible tire repair kit or an aftermarket spare that fits the published wheel-and-tire spec. Confirm the spare’s spec against the car’s published spec in the Tesla app. Don’t guess on wheel size or load rating.
NDOT’s patrol as a backstop
NDOT’s Freeway Service Patrol covers the most-traveled Las Vegas Valley freeways. Quality Towing operates it. GEICO sponsors it. The published hours are 5:00am to 8:30pm seven days a week. The patrol changes tires, jumps a 12V, adds fuel, and provides minor fire suppression. The service is free to the motorist.
The patrol is the no-bill backstop during published hours on a covered freeway. A slow leak on I-15 south near Primm at 6:00pm is a free plug. A slow leak at 9:00pm is a Tesla-dispatched contractor. Same kit, different bill.
What a local operator does that the kit doesn’t
Charge Pro LV is a referral line. We match Tesla drivers in the Las Vegas Valley with independent mobile EV rescue operators. The operator carries a tire plug kit, a portable compressor, and a 12V booster. They can plug a slow leak on a Kyle Canyon Road shoulder at 7,500 ft. They can also handle a 12V that won’t wake after a hot park. They can also add Level 2 miles if the pack is also low.
The operator quotes you before they start. They bill you directly. A typical session adds about 10 to 20 miles of range on a Level 2 charger. That’s Tesla roadside rescue. The same operator who plugs the tire can also add miles. One quote, one truck.
Plan for the shoulder, not the showroom
Confirm your Tesla’s published tire and spare spec in the Tesla app. Buy a tire repair kit if the trim doesn’t include one. Keep a portable compressor in the frunk. Save (702) 935-4699 for the cases the kit can’t fix. Save NDOT’s patrol for the cases the patrol covers on a freeway shoulder during published hours.

Frequently asked questions
Do Teslas come with run-flat tires?
Most Model 3, Model Y, and Model S trims do not ship with run-flat tires. Confirm your trim’s spec in the Tesla app.
Do Teslas come with a spare tire?
Most trims do not include a spare. Tesla publishes a tire repair kit per trim. The kit includes sealant and a portable compressor.
What if I get a sidewall blowout on a valley freeway?
A sidewall is a tow, not a plug. Call Tesla roadside or *647 for an Autura rotation tow. NDOT’s patrol can change a tire in published hours on a covered freeway.
Is a tire plug permanent in valley heat?
A plug holds by friction. Heat accelerates pressure loss around a damaged area. Roll to a tire shop after the plug and replace the tire properly.
