Specialized tires have been my go to for a couple of years. The butcher/T9/Grid Trail front and eliminator/T7/grid trail or T9/GridGravity rear combo are great beefy grippy tires that last and ride great. So I tried the GroundControl for my transition Spur. I got the soils searching, Grid casing for front and rear. They roll well and grip is really good but they have no side wall support. They are scarily squirmy at lower pressures, especially on grippy off camber sections and bottom out so easily. At trail speed I have had them fold over on corners and small 2ft drops. So I tried running them at higher psi then I normally do but they are like trampolines, bouncing all over the place. I suspect this may have to do with the soil searching sidewalls because the I can imagine the regular grid casing is this flimsy. I am a heavier rider so this maybe more pronounced for me, but it is so bad I am taking the tires off after a dozen rides because the casing performance is just so bad

The Ground Control T7 Grid has fantastic grip and damping that punches way above its light weight! It also a very fast rolling tire.

Really happy with these tires on my Rockhopper. Perfect blend of versatile performance on all terrain and they looks great! Super fast shipping from the great folks at specialized.com a bonus!

Handles fast xc and semi gnarly tech terrain well at high speeds. Have these on multiple bikes. Casing feels durable and light. Cornering control is predictable

Not going to lie, I originally bought the tires for the color. But dang I love these tires. Get up to speed fast, rolls east and grips great. Great trail bike/single track tire. Running this on a 23’ Stumpy, front and rear.

I run these front and rear on a Orbea Occam (specialized, I love y’all, but your bikes cost too much). Perfect tire for Florida trails as a good compromise between rolling resistance and grip, and they don’t wash out in sand (within reason). They even handled Black Mountain in Pisgah with no problems. P.S.- bring back the alloy Epic.

These tyres in 2.35/ T7 compound/Grid make for an excellent and surprisingly fast rolling trail tyre. Very fast ! They are almost XC in speed yet have enough general bike to handle blue to black trails. The casing lacks support and the edge knobs lack bite in heavier/gnalier terrain but that is not their purpose. Adding Cushcore allows them to be pushed somewhat harder if required. As a comparison they have better feel, precision and grip than say a Maxxis Rekon and roll faster too. They are a step below the control provided by say a Maxxis DHR2 in maxterra but really not all that far behind. Very impressed.

Grips and rolls

This tire just about exceeded my expectations. After trying a few different front tires, the Ground Control Grid T7 provides reliable grip, great rolling speed, and the casing has so far held up against jagged rocks, wet roots, and some smaller drops. I pair this with a T7 Grid Fast Trak on the back for a very smooth rolling rubber setup on my Ibis Ripley here in the southwest. From town rides to the high country, this tire performs. Would recommend, especially for the price!

Call me crazy, but I am running these front and rear on a Stumpjumper EVO Carbon Comp. From the gnarliest trail in Pisgah to the fastest flow I can find. I can hit any of it at full speed and not even question what traction I may have. They grip and will hookup. They are fast both up and down. I absolutely love these tires.
