Pro-Line Trencher HP Belted 3.8" Pre-Mounted Truck Tires feature a High-Performance herringbone weave pattern belt, molded  inside the relentless, tall and grippy tread of the Trencher HP tire. These are not your average belted tires! Made for All Terrain bashing, the Trencher HP 3.8" tires will not balloon or expand during use and will still provide the incredible grip that you expect from Pro-Line tires due to the soft M2 compound. Just like all Pro-Line's tires, they are proudly Made in the USA! Like the original Trencher X 3.8" tire, the next generation Trencher HP 3.8" is destined to become the ultimate, go-to Bash tire for your truck!

Please note that the Trencher HP tires are not meant to be extreme speed run tires and have achieved up to 75 mph or about 3,500 RPM under ideal conditions in testing. Over revving your Trencher HP tires could result in breaking the internal belt, which will NOT be covered under warranty. This can be caused by "diffing out" your tires or holding the throttle open while one, two or three of your tires are stopped, which substantially increases the RPM sent to the free-spinning tire or tires.

The Belted Trencher HP 3.8" tires come Pre-Mounted on the next generation 3.8" wheel design from Pro-Line, the Raid 3.8" Removable Hex Wheel! Imagine being able to replace a damaged wheel hex without needing to replace your glued tires! These Raid 3.8" wheels make this possible by using a unique 8x32 interlocking hex design that is secured to the wheel by 8 M3 screws that are spaced 32mm across. The hexes are included and are also available separately (6345-00). The built-in adjustability and ease of use make this a must-have wheel for bashers everywhere!

Pro-Line Trencher HP Belted 3.8" Pre-Mounted Truck Tires (2) (Black) (M2)
Im writing this review after running two sets of these tires and rims mounted on an Arrma outcast 6s v3 for 5 months. Repeated abuse, high speed runs, and major crashes, cartwheels, and rolls in equal amounts both on rand off road on asphalt, packed/loose dirt, grass, gravel etc.

Cons- Just one.

- Weight- They are on the heavy side and if you do drive like a psycho and diff out, you WILL continue to blow out diff gears, and driveline just like you did with your stock tires.

Noteworthy observations but NOT cons.

- Ride- Almost no flex in sidewall. All landing impact is sent straight to suspension components as there is nearly zero cushion in these tires (BY DESIGN)

- Stock servos' life expectancy will shorten as more tire surface area contacting the ground means more friction and more strain on the servo. Upgrade, and make sure your servo saver is tuned properly or even the high rent servos will fail. These tires grip quite well under normal use as well as throughout the entire crash... cartwheel, roll... etc..... and will murder your servo.

- Ground clearance reduced as ballooning has been eliminated.

- Top speed decreased as ballooning has been eliminated.

PROS- Many.....
Compound- Sticky AND durable. Tires last so much longer when the entire surface is always in contact with the road. Tread pattern is aggressive on all dry terrains.

- Wheelies for miles
On wet asphalt, wet concrete, wet grass, dry everything except deep powder dirt, sand and crushed limestone gravel.

- Ballooning nearly ZERO. Under .100" total diameter @55mph.

- Burnouts - Not really recommended but can be done on driveways with sealant especially when wet or on any surface when temps are below freezing.

- Stability- Increased due to the low profile sidewalls and almost no tire roll in turns.

I would recommend these tires/rims to anyone looking for a universal MT basher solution. Durability, traction, reliability.

I WOULD NOT recommend these to someone aiming for max air >/=20' height and the brutally hard landings that follow.

German Shepherd proof. While they aren't the greatest fit on the Sledge due to its width messing up the steering radius, they are pretty close to indestructible. He's managed to pop a hole through the spoke of the rim, bend the rim near the bead lock, and dead shake and drag my truck around when he catches me slipping up and I haven't had to replace them yet. If you're looking for a dog proof tire for when you let your dog chase it, these are the best ones hands down.

Don't waste your time or money on these over priced over sized Proline tires. First of all there is a video you have to watch prior to using them, Making sure your not ripping donuts or sharp turns in the tires cause it can still cause ballooning, which will blow the belt apart rendering them useless. SO 1st I feel like proline is hiding this from you prior to buying. The tire is completely oversized for any 1/10 to 1/8th scale basher. What i experienced when running these tires is a side to side wobble at high speeds, mostly unstable. On gravel i could not do any holeshots, the truck would always spin out. The tires are also so heavy that i couldn't get any wheelies going unless i tighten the clutch down causing way more wear and tear. I could also hear my steering servos struggling with the extra weight from tires. Then to top everything off amain would not return them cause i ran them for a whole 5 minuets. Wow. So now im stuck with these poorly designed over weight tires, when all i really wanted to know was how would they perform. DONT BUY THEM UNLESS YOU LIKE TOSSING YOUR MONEY INTO THE TRASH.
