Dunlop SP Sport Maxx GT
Experience quick, connected responses with the Dunlop SP Sport Maxx GT, a summer ultra high performance tire for sports cars and powerful sedans. A focused compound and tuned tread work together for crisp turn-in, planted cornering, and confident wet braking. The reinforced casing keeps the contact patch stable under load, so feedback stays clear at speed. Whether you are replacing OE rubber or chasing a more precise feel, the SP Sport Maxx GT delivers control and a refined ride for daily drives and weekend runs.
Key Features and Performance
The SP Sport Maxx GT is built around the essentials of UHP summer driving. A silica enhanced compound grips hard in the dry and delivers confident wet braking. A responsive pattern with a solid center rib and sturdy shoulder blocks supports quick turn-in and balanced cornering. Wide grooves move water away to resist hydroplaning, and a reinforced construction keeps the tire steady at speed and wearing evenly when alignment is on point. The result is precise steering feedback and dependable grip in warm conditions.
Sizes, Fitment & OE Notes
The Dunlop SP Sport Maxx GT comes in popular performance sizes for coupes, sedans, and sports cars. Common fitments include choices such as 245/40R18 and 275/30R20, with select staggered setups available. For the best match, follow the size, load index, and speed rating on your door-jamb label or in the owner’s manual, especially if your vehicle uses different front and rear widths or factory run-flat equipment. If you are replacing an OE tire, check the sidewall for markings like MO or RO1 to maintain the tuning your car was built around.
OE fitment tips for SP Sport Maxx GT
Many performance cars ship with OE specified versions of the SP Sport Maxx GT. Matching those codes helps preserve handling balance, ride quality, and the way stability and traction systems are calibrated. On staggered setups, keep the specified front and rear sizes, and make sure both tires on an axle match in brand and model. Switching between standard and run-flat types changes puncture behavior, so check your owner’s manual and follow the vehicle maker guidance before you buy.
Run‑Flat (DSST/ROF) Options
Select SP Sport Maxx GT sizes come in run-flat form, typically labeled DSST or ROF/RFT. Self supporting sidewalls help the tire carry the vehicle for a short distance after a pressure loss, so you can reach a safe spot or service bay at reduced speed. Use run-flat tires on vehicles engineered for them, and replace in axle pairs when possible to keep handling consistent. After any puncture, follow the speed and distance limits in your manual and have the tire inspected internally before reuse.
How run‑flat technology helps in real use
Run-flat versions of the SP Sport Maxx GT support limited mobility at reduced speeds after a loss of pressure. That can spare you a roadside change and keep steering more predictable than a fully deflated standard tire. Internal damage is still possible, so every puncture requires an inspection. Rely on your TPMS, observe the speed and distance limits in the vehicle manual, and replace run-flats in axle pairs when you can for consistent response.
Tread Life, Noise & Comfort
As a summer UHP tire, the SP Sport Maxx GT puts grip and steering precision ahead of maximum mileage. It performs best in warm weather, and it should be stored or swapped out as temperatures fall. Regular rotations, correct inflation, and proper alignment are essential to even wear, especially on cars with aggressive camber. Road noise is well managed for its class, and the ride is firm and composed to keep feedback clear. For the longest life, stick to rotations and avoid cold weather use.
Price & Buying Guide
Pricing for the SP Sport Maxx GT depends on size, speed rating, and whether you pick a standard or run-flat design. OE marked versions can be priced differently based on the automaker spec. For the best value, confirm your exact size and load and speed needs, compare standard versus run-flat, and include installation, alignment, and road hazard coverage in your budget. If your car is staggered, plan to buy in pairs to preserve balance. Check current promotions and stock before you book an install.
SP Sport Maxx GT vs Alternatives
Shoppers in the summer UHP class often cross shop tires like Pirelli P Zero and Michelin Pilot Super Sport. The SP Sport Maxx GT leans into direct steering feel, strong wet braking, and OE friendly fitments, while some rivals favor longer tread life or a softer ride. Your best pick depends on what you value most, ultimate dry grip, wet traction, comfort, or longevity. Compare sizes, speed ratings, and whether you need run-flat capability. If your car shipped with the SP Sport Maxx GT, sticking with the OE tune can make selection simple.
