We take Ford’s hot-rodded SUV, the Explorer ST, and prepare it for off-road and snow life with the help of ALPHAequipt Grenade wheels and General Tire’s Grabber A/TX.
The Explorer ST is Ford’s 400 horsepower, 415 lb-ft of torque performance SUV powered by a 3.0L twin-turbo EcoBoost V6 that features a 10-speed transmission, (optional) All-Wheel-Drive, and a handling-focused suspension tuning.
Ford’s ST (Sports Technologies) vehicles have built a reputation for being extremely engaging and fun to drive vehicles, like the Ford Fiesta and Focus ST. The Explorer ST adds to the lineup and is meant to provide a lot of versatility for any occasion and destination. We must admit that this is one great-handling, fast, and fun to drive SUV worthy of the “ST” badging.
We know that defining the use of the tire is the first step when Sizing and Selecting a Tire for PERFORMANCE. We plan on taking our Explorer ST into heavy off-roading and snow conditions, so we are going to need an “On-/Off Road All-Terrain Tire” with a Three-Peak Mountain Snowflake (3PMSF) rating.
Since our tire requirements called for a tire category that was not offered in the 21-inch stock wheel size, we were on the hunt for a smaller performance off-road wheel to be used with a tire with a fatter sidewall. Fortunately, ALPHAequipt’s Grenade wheels are available in Explorer-specific fitment of 18×9 +35 offset and a 5×114.3 lug pattern. This is the same fitment as the Subaru Forester, Toyota RAV4, Mustang, and is the same width and only 2.5mm more offset than the stock Explorer ST wheel, so we were confident that there would not be any issues with clearance or drivability.
ALPHAequipt has been around since 2019 and are often found on many Ford F150s and Raptors in addition to Toyotas, Jeep 4X4s as well as niche vehicles like the Mercedes G-Wagon, Porsche Cayenne and Subaru crowds in the off-road and “overlanding” communities. We are one of the first Explorers to use ALPHAequipt wheels which have a great size and application for this model. 17×7.5 wheel options are also available with +35 and +15 offsets for Explorers with smaller brakes looking for even larger sidewall tire options.
All ALPHAequipt wheels feature dual-valve stems, one of which is heavily shrouded to protect expensive TPMS sensors from damage during extreme rock-crawling. The Grenade’s lip features an aggressive pattern that adds a lot of character to the wheel.

FYI – the 60,000 mile does not apply to LT tires. The quoted load limit over stock require 80psi. Twelve additional pounds per tire over stock leads me to believe your MPG math might need some work.
Calculating MPG isn’t difficult (Miles driven / gallons used), and after many road trips the result is the same – a negligible difference in MPG with this off-road tire setup, which surprised us. Tire weight does not affect MPG much under steady-state driving on the highway. Rolling resistance is the primary factor when it comes to affecting gas mileage and nearly half is caused by the tire tread and construction and aerodynamic drag also plays a significant role. Thus, the width and tread do not create much more drag than the OEM setup.
Is ALPHAequipt still in business ? I’m ordering a 2025 ST and their website is offline as in really offline
