All Season tires

primary

This tire has good wet traction, which means that drivers should 
                            expect solid grip on wet roads. As a general rule of thumb, traction can vary based on 
                            driving and maintenance habits and road conditions.

Good Wet Traction

This tire has a great speed rating, which means it can safely handle 
                            speeds between 130mph and 149mph without the risk of failure. As a general rule of thumb, 
                            posted speed limits should always be followed and proper tire maintenance and 
                            rotation can help prevent failure.

Great Handling

Grandtrek PT21

Finding a tire that performs year-round is a must for most drivers, as dry, wet, and winter weather conditions all present different challenges. Fortunately, all-season tires are built to handle these conditions, and the Grandtrek PT21 from Dunlop does that and more for drivers of CUVs and SUVs. Four wide grooves and open shoulders force water out of the tread to reduce the risk of hydroplaning on wet roads, and the Grandtrek PT21's dense siping bites into the road to increase traction. A low rolling resistance design enhances fuel efficiency so that drivers can go longer between filling up their CUV or SUV, and the Grandtrek PT21's symmetrical tread pattern fights off uneven wear for a longer tread life.

Best Rated All Season Tires

Dueler H/P 92A

Kenetica Touring A/S (KR217)

RB-12 NWS

Like  their name suggest, all season tires are designed to give drivers performance year-round. All-season tires often provide strong performance in dry and wet conditions, and suitable traction and grip in wintery weather.

Vehicle

This product is not covered by a manufacturer’s treadlife warranty.

Mileage Warranty

The maximum carrying capacity for a tire determined by the manufacturer.

Load Index

Maximum speed capability to safely carry a load for an extended period of time.

Max Speed

The maximum load carrying strength at the specified inflation pressure, also known as ply rating.

Load Range

The side of the tire between the tread and rim, with cosmetic branding as well as information about the tire including manufacturer, model, size, etc.

Sidewall

Standards that measure treadwear, temperature resistance and traction, example: "640 A A".  The 640 is the treadwear test and it lasted 6.4 times longer than the comparison tire tested against.  The first "A" is the traction rating using straight-line wet traction on test surfaces (see information tables tab) and the second "A" is the temperature rating by testing operation at high speeds without heat-related failure (see information tables tab).

UTQG

Wet Traction is a piece of the UTQG for example if  UTQG is: 500 AA A, the wet traction piece is the second piece, the "AA".

Wet Traction

Measured in 32nds of an inch, this metric shows how much tread life is left on a tire, with the tire's traction & stopping capabilities greatly diminished at 4/32nds and less. Tire manufacturers include "tire wear bars" at 2/32nds to indicate when your tire is worn out.

Tread Depth

The highest inflation pressure (measured in pounds of force per square inch, PSI) the tire is designed to contain, and should only be used when called for by the vehicle placard.

Inflation Pressure

An identifier of a particular tire line and size combination assigned by the tire manufacturer.

Part Number

Tread design (or tread pattern) can affect handling, traction & noise for different driving styles & road conditions.

Tread Design

Tire Weight

The measurement of width from a tires inner sidewall to the outer sidewall.

Section Width

The range of widths the rim of the vehicle can be for this tire to be safely mounted on.

Rim Range

The diameter of a tire that is inflated without any load applied.

Overall Diameter

The Dunlop Grandtrek PT21 tires offer good performance in various conditions, particularly in snow and off-road situations. However, the short tread life and potential for early wear are significant drawbacks for many users. The tires seem to perform well for off-road and winter driving but may not be the best choice for those prioritizing longevity or quiet highway driving.

The Dunlop Grandtrek PT21 tires receive mixed reviews, with some customers praising their performance while others express disappointment with their longevity and traction.
