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.

Great tire for aggressive XC riding. Plus, rode the Colorado Trail on a set of these and didn't get a single flat.

Enduro bro who recently picked up an Ibis Ripley for XC style riding. Running these front and rear. Tires have super grip on all terrain, fast rolling and lightweight! Tan sidewall looks killer! Definitely recommend. A++

This is my third set of Ground Control tires. For the riding I do they are perfect. (East Coast, Wet Rocks and Roots, Lots of Pine Needles) Fast Rolling, Great all-round traction. Took me awhile to get used to the white walls, but I think they look good, my Stumpjumper Pro., and it is for a good cause.

Loving the tires - got them for the front and rear. Grip and control are great. The tan wall look against the matte frame is a killer look! With the sale price, it’s a no brainer on my Specialized Epic Expert.

Great tire… Cross country and mountain.

Looks great. Rides great. Wicked grippy. Lighter and faster than your typical maxxis DHR/DHR style design. I like them so much I bought a back up set a week after I mounted my first set. I ride mostly single track, no massive drops or jumps.

great balanced tire. run front and rear, rolls great. only a few rides so far though.

They look pretty and also, the most important, have very good grisp when have xc or light trail rides. And for me, the only downside is it's a little bit hard to install for the bead design.

Tire rides real nice!

Awesome tires love it! Highly recommended.

Grippy but still roll decent. Looks fantastic! I have them on my Epic Evo for shoulder season.

My first ride with these I had set the tire pressure at around 20 psi and I felt that they didn't have much grip. But after some deduction I figured out I should be at around 16 psi and that has made a big difference. The grid casing is actually quite sturdy and thick so it can handle lower tire pressure pretty well. I would have thought 16 psi was way too low for a 29x2.35 tire but I was wrong. Now that I've ridden them for 2 months I can say they work great for my riding (dry midwest). They don't grip like a DHF but that's ok. They are noticeably fast rolling and have enough grip for me to still have confidence on hard trails. Super versatile tire. One major downside is they were 10/10 difficulty to mount onto my wheels. It was so hard omg. I had to use a tire lever to just put the first side on... A super gorgeous tire too. Cleanly designed and the tread even looks kinda cool (if that's possible?)

Wanted a faster and grippy front tire for most of local mostly XC trails, tire doesn't disappoint. Tracks really well on hard pack and loose pebbles. Really like the tan sidewall too.

I recently got an ultra light XC hardtail that came with Aspen rear and mezcal front, but I was getting bumped around and rattled after the front tire lost traction several times in the loose and dusty Utah conditions. I switched to these and it completely changed my bike for the better. FAR more grip, no washouts yet, and a much more comfortable ride. As a result, I'm faster on everything except for tarmac and pristine gravel.

Knobs are too too soft. Carcass rolls great, though.

high ground speed, fast rolling, excellent grip. retains sealant and pressure very well.

I love these tyres. Just bought another set. Super-grippy on wet rocks and roots, and hook-up well everywhere else. Very well made with solid side walls and versatile tread pattern. Very easy to bead and inflate tubeless. Hopefully these become a regular item in the catalogue. I use these on my rigid singlespeed across a range of terrain and they work for me.

Quiver killer, do it all tire. The ground control is surprisingly light, exceedingly grippy and predictable, and delightfully fast rolling. It's at home on gnarly trails and even some XC race courses. The ground control is endlessly impressive; especially in the softer T7 compound. Highly recommend

Best trail / XC tire I’ve used to date. Great balance of rolling speed, grip, and toughness. Rubber compound in T7 has been great on wet rocks -

I switched to these after trying some Eliminator T9s as a rear. These were a great upgrade for my riding style. They provide a faster rolling tread and the T7 isn't quite as tacky as the T9, yet still keeps you connected to the trail. I've tested these through rocks, roots, mud and and even a little snow and they've held their own. Big S is on to something with these new compounds, and you can't beat the price!

Amazing grip, surprisingly fast rolling and reliable like a best friend. I don’t feel slowed down at all when comparing these to my past racing Ralphs. The compound is pretty soft for XC tires, but you have enough tread, that they’ll last long enough. I’ve had really bad experiences with control casing so I wouldn’t dare use anything without grid. The extra weight is worth it, and I cannot stress this enough. I personally can’t see needing anymore grip than this tire provides. If feels more aggressive than previous generation. I haven’t tested these in mud, snow, or wet. They were a little tougher to mount than other specialized, schwalbe, and maxxis tires I’ve had, but still didn’t need anything beyond a floor pump and some love.
